[QUOTE=bjohns86;75126817]dbdedel,

"Thank you for the kind words. I appreicate your vigor and and curiousity, these are qualities often missing from both professional and amateur mechanics........"

Sorry for my late reply Brad, spent some time studying about electricity since my knowledge of these was decades ago and i had to refresh my memory of the ohms, amperes, volts which even during my secondary days were Greek to me.
Actually i am empowered by you and the other kindhearted enthusiast who have taken interest in my problem. All of you are encouragers and i'm learning and doing things i've not done before only because you've motivated me.
I'm taking into consideration the "Sports Mode" aspect of the car. However, there are three terminal at the top and two at the bottom and right now i'm still trying to find in the Bentley diagram their connections so i can work on the principles you've outlined. You're description of the shifter is right, it's PRND321. I'll give a feedback of how it comes out, you're right also in that we should rule out the simple matters first. After of which if the problem has not been resolved i'm going into the information outlined by rychas1.
I hope that your New Year and the coming year will be blest. This is my wishest too for the rest.

[QUOTE=CoolAirVw;75131612]With regards to the 91 corrado dbdedel.

You can scan the trans computer with vag-com. If you have a 4 speed this needs to be your first step. If you have a code this might point you right to the fix.

Thank you for your kind concern, i appreciate your interest and sound suggestion. I think i will have it scanned again because it seems the VW shop i went too the first time did not give me the correct diagnosis. That might make matters a lot easier for me and everybody who have taken interest in this matter. I'll also look under the transmission.

[bjohns86]

dbdedel,

Also, email me (bmjohnson@huskers.unl.edu) and I will send you those PDF's with the wiring data sheets and diagnostic data.

[dbdedel]

I hope everybody (rychas1/bjohns86/CoolAirVw) is doing well and that your tasks are all met with success. Everybody has given their wise share of knowledge regarding this matter and this is just a quick note of give an update of my cars problem. As suggested by bjohns86, i started with the Sports Mode Switch, installed a used one i purchased from a Vortex member and for the first time the transmission shifted from third to fourth. However, I also had the automatic transmission scanned as CoolAirVW suggested and I was given the following readings:
Address 02: Auto Transmission Labels:095-927-731.lbl
Control Module Part Number: 095-927-731 F
Component and/or Version: Digimat 0605
Software Coding: Diagnose VW
VCID: 2142EAA6ABD2CAC
00293 Multi Function Switch (F125) 25-10 Unknown Switch Condition – Intermittent
00518 Throttle Position Sensor (G69) 16-10 Signal Outside Specifications – Intermittent
00529 Engine Speed Signal Missing 35-10 Intermittent
00596 Short Between Solenoid Valve (or Injector) Wires 35-00
00263 Transmission 04-10 Mechanical Malfunction Intermittent
65535 Internal Control Module Memory Error 00-10 Intermittent
The VW technician erased all the codes and advised me to come back after a week to check if the codes come back. However, the transmission often returns to the original problem and I reset the transmission as rychas1 always advised and transmission shifts from third to fourth again. I have yet to check the solenoids. With this initial feedback perhaps somebody could give me an initial idea where the problem lies and what should be my next move.
I appreciate all your assistance and I wish everybody “a good day" !

Thanks to the contributors on this thread and forum.

I'd spent the better part of a year rebuilding the engine in my wife's 99 cabrio and did not have a transmission problem before the engine rebuild.

After I got the engine back in and running I was in limp mode. I came to the AT forum looking for some clues for my 01M, found this thread and kept going back to the solenoid wire harness.

Tonight, I pulled the bracket holding the round connector on top of the transmission and straightened all the kinks out of the harness from there to where it enters the transmission. Took the car out one more time and it shifted perfectly. Cleared the codes and none returned.

I still have to figure out if it was a kink in the solenoid harness or just not making good contact on the round connector. Right now, I've got a big smile on my face. Thanks!

[dbdedel]

I'm glad at that big smile on your face. I hope to have that big smile too, i tried what you did, cleaned both plugs with electrical cleaner but my problem has not been resolved. At least i know that my 096 is now shifting from third to fourth.....occasionally and one day i'll finally have the same big smile. Have a good day and thank you for sharing.

Hi! Good morning, just a quick word that i'm going over diligently on the postings you have started knowing i will find an identical information that will resolve the issues of my 096. Likewise, i'd like to express my appreciation for advising the priority of the Sports Mode function of the transmission since as i have mentioned has made the shifting work. I'm not sure if a new Sports Mode switch is the right approach but i'm looking at all the other concerned enthusiast who shared their experience.

[CoolAirVw]

The VW technician erased all the codes and advised me to come back after a week to check if the codes come back. However, the transmission often returns to the original problem and I reset the transmission as rychas1 always advised and transmission shifts from third to fourth again.

When your trans "returns to the original problem" your trans computer is triggering a trouble code. When you "reset as ryshas1 advised" you are clearing the code.

You need to see what code is coming back.

[bjohns86]

I agree with CoolAirVW, you need to figure out what codes are recurring. From what you posted, I don't think the problem is inside the transmission, including the internal harness. It looks to be harness related, whether it is an intermittent short or open circuit, I don't know. The obvious would be to look for breaks in the protecting conduit around the harness, pinched wires, loose grounds or corrosion. Odd ly enough, even significant corrosion on the battery terminals has been linked to transmission problems on Jaguars and Ford vehicles. You said that you check all of the obvious connectors for corrosion. Did you check the multifunction switch with the data I sent you to verify that all of the contacts are opening/closing when commanded?

Hi all
My daughters 2000 beetle is in drive all the time, IE park,reverse drive and so on. would this be cause by connectors and wire harness? or is the trans and valve body problems ?

thanks guys it's been a great write up

This question really should be in its own thread...forum protocol is that if you problem doesn't directly relate to the topic at hand, then start your own thread, which I realize you dont know if it does or not, which is why you should've started your own thread but .....

First of all determine if your shifter cable is hooked up and working. If your car will start in park and neutral but not in reverse, drive, 3, 2 and 1 then its working. Also verify it latches in park and rolls when not in park. It also doesn't hurt to have a helper move the shifter while you look at the linkage on the trans to verify its working.

Or maybe just look in vagcom data groups to see that the "range" is changing on the range sensor (f125).

After that if its all ok, you should pull the pan and inspect for metal contamination indicating blown up planets. If your pan doesn't look like a silver mine, then look to make sure the manual linkage is hooked up to the manual valve have your helper move the shifter to see that its working.

Planets can break up so bad that the trans locks in forward. Also the forward clutch can burn up so bad that it welds itself together and is on all the time. Usually this makes bind up in reverse but after a while reverse can burn out too and your left with forward movement in reverse.

Probably your gonna need a trans.

[dbdedel]

I agree with CoolAirVW....
Brad[/QUOTE]
Thank you for your advise Brad and also to CoolAirVW, i appreciate it. I'm very sorry for my delayed response, i've been away for days and i just returned. As i have mentioned earlier, i've resolved to deal with the issues notwithstanding the fact that this is the first time i would do so and ironically the matters are beyond my simple know how, not only because i like the car but i think it is because there are kindhearted guys like you trying hard to assist me. I've become morally obliged to make your time worth, i appreciate you guys. I hope that in your kindhearted efforts all your tasks are blest in return. I'm comforted by the fact that the matters to be resolved are becoming more simple, initially i though i would go through the valve body and solenoids. As CoolAirVW advised and as you confirmed it Brad, i will have the transmission scanned to know where the problem is coming from. It might be good new to tell you that when i had the transmission scanned, the technician mentioned something about some wires being shorted. I'd look into that and also the connectors. How do you exactly check that "all of the contacts are opening/closing when commanded?" Have a goo day. david

[CoolAirVw]

It might be good new to tell you that when i had the transmission scanned, the technician mentioned something about some wires being shorted.

If and when you have it scanned again write down the code and the definition.

Clear the TCUs, check all connections for cleanliness, and drive/rescan. If it persists, then address each one separately.

Im planning to replace the wiring harnes ..which is the rigth one?

[super561]

i have a 98 beetle 2.0 it will not shift out of first gear, and every time i accelerate the car stalls. i can only accelerate very slowly up to about 30 mph and still won't shift, and goes into reverse easily. i have seven codes from the regular scanner, they are:
p0753 shift solenoid a circuit electrical
p0758 " b "
p0763 " c "
p0768 " d "
p0773 " e "
p1778 manufacturer control transmission
p0748 pressure control solenoid a circuit electrical
also the ac, power windows, rear hatch, or interior lights are not working and the fuses are all good. the radio is not present. i am mechanically inclined, i have taken apart neon transmissions and valve bodies and fixed and just recently rebuilt a 2001 oldsmobile alero 2.4 engine. i found this thread and starting reading from the beginning. please help, this car is killing me. and thanks to all ahead of time, and these threads are appreciated and very helpful to people like me and alot of others. thanks again.

I know that you won't want to hear this, but you MUST scan with vcds/vagcom because the generic codes and exactly that...generic. I gives you an idea, but not always precisely the direction to go. I recommend, assuming that you just don't have access to vcds, to clear the codes, drive and rescan. If the same codes reappear, start with checking all your grounds. The A/C, windows, and such are not on the internal harness circuit, but they may share a common ground in the engine bay. Check those on the transmission and the front block, and under battery..all of them! The key is to try to isolate the codes before you dig in there. Report back.

Hi everyone. Pardon my noobness but I'm new-ish to imports. Was a strictly american make kind of gal until I got this VW. Had it 5 years now, never had issues with anything major that I couldn't handle. But now I am stumped.... Here's the history:

Took it to a local shop because of "ticking". They replaced the flex plate between the tranny and drive train, the timing belt, serpentine, etc. Nothing major. But they did have the tranny out of the car.. This was between March 8th and 16th this year. Fast forward to March 28th and it starts having shifting issues. Mainly it started with selector problems, P to R fine, R to D would get stuck in N. Seemed just to be a little glitch. Next thing I know, it goes into limp mode on me last night. Display on the panel is solid black in the background after about 2 minutes of driving, definitely stuck in limp mode/3rd. I don't have access to a vagcom but I did get a generic OBD-II on it and it's coming up:

P1778 Solenoid EV7 Electrical Malfunction
P0753 Shift Solenoid A Electrical
P0758 Shift Solenoid B Electrical
P0763 Shift Solenoid C Electrical
P0768 Shift Solenoid D Electrical
P0773 Shift Solenoid E Electrical

ABS light has come on and gone off for months. I'm thinking there's faults in the ABS control module. Maybe lack of communication between the ABS control module and ECM?

I also called the shop that I had taken it to for the repairs mentioned above and they basically told me that I needed a new tranny and that I could set up an appointment. After reminding them that they had the tranny out of the car less than a month ago and now it's suddenly having issues, they told me that there was no possible way that it what they did could have caused this. My gut feeling tells me that when the tranny was hooked back up, something wasn't done right somewhere. I haven't touched it yet. That's basically why I'm here. With the faults being all electrical and all solenoids - I highly doubt there is any way that they could all go bad in one shot like that. So, my question is where do I start? I'm totally willing to get my hands dirty here because I'm sick and tired of being ripped off by mechanics who see a woman and think I don't know anything. I spent most of my childhood and teen years learning american makes and I haven't done much besides regular maintenance on this being that it's an import.. But you gotta start sometime. Figure I might as well learn now.

If I need to get a vagcom reading on it - where can I do that? Are they expensive or do I have to go to the dealership and bend over? Just curious.

Wow. You go girl! As with the thread before yours, start with the basics. A bad tranny ground can cause this, especially after some time to work its way loose. A unsecure connection. VCDS can be had on rosstech.com, ebay, or just look on the vortex thread for vagcom owners. You may find one near by your location. Eliminate the basic stuff and then we can determine if it's your actual harness that's bad.

[super561]

is the vcds (vag com) just a software disc and the cable, and you just upload the software to your lap top? or do i have to buy a special vcds computer tool?

[rychas1]

the former. actually its just the cable and the download from rosstech.com. the ebay cables work fine with the old 409.1 version 3rd party version.

[super561]

the former. actually its just the cable and the download from rosstech.com. the ebay cables work fine with the old 409.1 version 3rd party version.

i just ordered the vag com cable that came with the downloadable software off of ebay but they said it does'nt include the license, so what can i do about that? and i ended up taking my beetle (mentioned above in an earlier post) to a guy that repair only volkswagen, (mostly beetles) but he said when clears the codes from my transmission, after a few seconds all seven codes pop right back up. what could be the cause of this? and my throttle body won't accept the tba. i mentioned the cable but i just ordered it right before i came to the thread tonight and my car is still at the shop, so i have'nt had a chance yet to try the cable myself.

[rychas1]

Did you check all the other stuff mentioned earlier?

[super561]

ok, my car has just been sitting at this shop. before i took it i checked all the grounds except the one under the battery tray and by the driver headlight. (probably the culprits since the car had work done to it before i bought it)
the guy at the shop said he reprogrammed the transmission with vcds and it was good for a minute then all the codes reappeared while still hooked up to vag com. he also told me i needed a throttle body because it would not except tba. i bought a tb and still would not adapt. why would'nt a tb adapt? what could be the nature of these two problems? would the harness let the trans be fixed by reprogramming then go right back to all the codes? please answer, i need my car from this place today after trying to adapt tb he was pressing the accelerator and you could see on the computer screen the percentage i guess of the accelerator being pressed... i dont know.

Just replaced the trans ribbion,and cleaned the valvebody and solenoids,no more codes car seemss to shift smooth so far

has to be perfectly lined up. they are the same size. there might be a fraction of a millimeter of clearance around it.

nope. the numbers are directly from the repair manual.
