    Thread: '02 1.8T Jetta not shifting gears from 1st, when cold

    1. 11-12-2010 10:29 AM #101
      Another to the list! success. fixed and now shifts. I also had another problem with my jetta that i didn't notice anywhere else. It started downshifting itself out of 3 and 2 and reving up to 7+ rpms. N92 fix it as well. took me 14 hrs with a few breaks and problems.... Had alot of trouble with the pan. You need all the wires as FAR BACK as possible. Plus the gasket isn't a lifetime gasket. its just sealant so have some "Just Right" around for the reassemble. Hope this helps. thx to everyone. VW owners need to stick together. This was an amazing thread.

      I had the same problem with hard shifts and not shifting out of 1st gear when cold. I replaced all 9 solenoids from cobra transmission and refilled with Amsoil Synthetic ATF. I did this at 187,000 km's and it now has 202,000 and still running great. One other note is I was only getting an error of implausable signal from my vag but no cel. I actually tested the old solenoids that I took out with a multimeter but couldn't find fault with them??? Not sure why but they were definitely faulty. Anyway, just my 2 cents.

      I have an 04 Jetta that is having the same shifting problems. It is also a 1.8T. Would it use the same parts as listed on this thread for the 02 and 03 Jetta?

      Thanks

      Yes. I would suggest changing all the solenoids.

      6-months ago mine 2002 Jetta 1.8T Tiptronic started showing some shifting problems when 1-2 and 2-3 and little bumps as the tranny shift to 1st, just seconds before stop. The colder the weather the worst the problem and got better after runnning for a while. Going up on a hill while waiting for a green light I must keep the "break-on" otherwise I start going in reverse. Except this reverse issue all other stuff happen 90% of the time, 10% is OK.

      Is there any logical relationship between the shifting/reverse problem and the possible solenoid N92 solution?

      I really will appreciate your comments.

      Your transmission has no function to prevent rolling backwards on a hill. This is not a trans problem.

      All problems sound similar to one i'm having with my 01 gti. has anyone had problems with engine stalling when cold and trying to engage either drive or reverse? The annoying shifting problems almost all seem to be present. Also, car always feels sluggish coming off a stop.once it starts rolling it's ok but feels a bit like tranny slip initially.

      thank you! thank you! thank you! to anyone and everyone who posted the n92 solenoid fix for shifting problems when jetta is cold! my 03 wolfsburg has 190,000 miles and runs like a new one. this winter i started having the shifting problem when my car was cold. if i did not let it warm up for 10 minutes it would not shift from 1st to 2nd. my mechanic originally got a code for the transmission temp sensor and he changed it. turned into a chore since the temp sensor is part of the transmission harness. this fix did nothing to change the shifting problem. took it back and it came up with no codes at all. did not know what else to try. i love and trust my mechanic and refused to take it to a dealer just to have them tell me i needed a new transmission. thats when i found vwvortex. i printed out all of your advice and took it to my mechanic and asked if he was willing to try the N92 fix. he was and im off and running! gonna try to get to 300,000 miles now!! you guys rock! thanks!

      My jetta is stuck in first gear... The malfunction light is on and the torque converter makes a whining noise... Help

      Hello,

      I had the problem also that with a cold motor the gear didn't shift from 1/2 to higher gear. Only after 15 min. with warm engine there was no problem. Also tried with max rpm full gas, it worked (this was a tip in this threat). So I thought I had the same problem like a lot of people here. So I replaced the N92 solenoid this weekend. IT WORKED ! All my problems are over. THANKS
      The n92 was kosting about 70 euro. Not much because a renovated gear inc working will cost about 1500 euro.

      Thanks for the tip, it helped me a lot

      My second post only to thank you kind folks. I was panic struck when I became a victim of N92. Was on a trip and from motel no gear but R and 1. No shift. Who on I-95 knows diesels more/less a vw. I had money gremlins dancing in my head. My beloved 04 TDI 186K is biting the dust and I need this car. Never changed the no muss no fuss forever sealed unit for oil change. Not necessary, Yeah sure. Learned that fable too. At least after it kicked in, and drove perfectly I noted the cool had something to do with this. I searched and you guys were on with a real TIPTRONIC 101 course.

      You folks gave me peace that at least I won't have to drive 800 miles at 20 mph and 3000rpm.

      Bless you and I will be changing that oil just to start the purge process until I can afford the whole solenoid harness. If I go to that trouble, May as well catch the next gremlin. What takes you folks 4 hours will take me 4 days. I hate working on cars although I can. Too old for that now but too broke not to attempt.

      Luv ya all. May stick around a bit. Lynn (I'm a guy) (I know, Alice Cooper has the same problem)

      I was wondering if anyone used a gasket or some sort of sealant on the transmission pan when they reinstalled it. If so, what kind and what was the part number.

      Not knowing, I ordered a gasket when I got my solenoids from cobratransmissions.com. Found out that VW doesn't use a gasket, so I just used silicone sealant when I put it back on. Make sure to get both surfaces clean & oil free. Gasket P/N from Cobra was 98301, but you shouldn't need it (must be used on the same trans from Mazda, LR, Jag ...)

      Thanks for the response Charlie! Did you change out all nine solenoids? How tuff was it? Appears to be pretty limited access. Im only going for N92. Hoping it fixes my "not shifting out of first when cold" problem. Thanks again.

      If you pull the front end into the "service position" you should have enough room - If you want more, pull the front clip off.

      I replaced the N92, which fixed my problem. Then, 5-6 months later, I wound up replacing all 9 because I lost reverse when cold.

      If you plan on keeping the car, I would suggest you do all 9.

      I got the set of 9, replaced 8 of 9. (Last one was behind a wiring harness and it was getting late, so I didn't change that one. It was not testing bad, and I still have it in case I need to change it in the future). Set of 9 is much cheaper than getting them one-by-one.

      I didn't put the front end into service position. If you have done that before and know what you are doing that may be a faster way, but I had just gotten the car so I followed the "09A solenoid change howto" and it went fine. Toughest part for me was getting the pan back on, there is a stinking vent tube that makes it tight. Hint: put the silicone on the tranny surface, not the pan; that way you won't smear silicone on the valve body trying to maneuver the pan into place

      I am also having trouble with the shifting on a 2002 1.8T 09a. I think mine shifts out of first - it goes past 5000 RPM at about 20mph or so - the Vagcom shows that I am in 3m gear, and I can get it to shift into 4th if I race the engine and let of the gas etc... I just hate doing that. Once in 4th it will shift nicely into 5th. Not getting any transmission codes, but I am getting a few engine codes.... 17705, 16891, 16684, 16885, 17544, 16687, and 16686. I also lose communication with the transmission while driving it. It will come back if I try to go to a certain block, show some data, and then lose communication again.

      Here is my main question... First I am willing to try to change n92 - sounds like a cheap fix to a potentially very expensive problem..... Should I change them all? Gets a little more expensive, but looks like a fair amount of work, why do it twice?

      Second, solenoid change - does it sound like it will fix my problem?

      Wish I had more history - I just bought this car at auction. I don't know if the symptoms started out like others on this thread.

      Any advice would be appreciated!

      I have to wait 15 min before my car will shift
      Out of first but after that it's shift fine
      Took to to a shop and they are not finding any codes
      Should I replace the n92 anyways. Because if this don't
      Work I'm just going to trade it in.

      RadLynx,

      Whay would you replace all of the solenoids? I can see it if it is because it is cheaper as a set or that you just want to throw parts at it to solve a problem, but many people replace the N92 solenoid and don't know what it really does. The fellow you quoted did not diagnose the problem and was bitten 6 months later. This may or may not fix your problem, but diagnosing the issue will increase your success rate and save you money, though it often takes more time. Just food for thought.

      Ralph c,

      Why are you replacing N92? If you are just having a problem with the 1-2 upshift and not the downshift or any other shift than I would dig deeper. Do you want to diagnose this or just move on to the next option? The N92 energizes in 1st and de-energizes in 2nd. You will likely never find an on/off solenoid plug during exhaust (de-energized); more often when it comes time to seat and charge a circuit. Do you just get no 1-2 upshift until warm/hot or does the 1-2 shift slip? If you really get into the throttle, will that cause a 1-2 upshift when cold? Any other shift complaints?

      Good Luck All!

      Brad

      yes, your problem is probably caused by the n92. You should probably change them all.

      I'd have to check my credit card records, but I remember this much. Buying 1 (N92) solenoid from the dealer was more than 50% of what the kit of 9 cost me.

      If I had to do it all again, I'd replace all 9 off the bat.

      The only reason why I didn't do so in the first place, was my reluctance to spend money on a solution I wasn't 100% on. If the N92 replace didn't fix the problem, I was going to do a manual swap.

      So far it's been 2+ years, and I'm still pleased with the results. The only problem that still exists is a "flare" between 1-2 shifts when the transmission is cold and under heavy throttle. The car has paid itself off , so I'm comfortable with living with that.

      This thread (and it's contributors) are a wealth of information. Read the posts, educate yourself and save money!!
