First I must say thanks to all the people who were at VW Show and go on April 15.
I was the one with over 250 bad reverse gears on my table (Mt. Reverse), a few sample stripped gears, and a few trans.
I answered every tech question concerning transmission 020, 02J, 02A, 02M, etc. the best I could.
As for the guy that broke the axle while racing the MK4 GTI, you are a lucky man...luckly I was there with the impact gun, jack, my friend with the axle nut socket, axle bolt tools to remove the axle. And his friends for helping as well as poking fun.:laugh: No right side axles were available in the swap meet, so the guy went out shopping at the part store, found one. Jacked up the car, pulled the axle, installed the new one and whalla... she's done. Saved you alot of $$.
Keep the trans concerns coming, there are many of us on here that can :laugh:help y'all out.
hey i recently changed the fluid in my 07 GTI @125000km (75000mi). The old (original) fluid was black, smelled bad, and there were some little gold colored filings in it. Having said that- my gearbox never felt bad in any way, shifts always been precise and smooth. I re-filled with the OEM fluid and it's as smooth as it's always been.
Question is- how often do you think a MT fluid change interval should be?

I just sent you a pm regarding this question but I will also post up here.
I am looking at doing the 020 5th gear conversion and I saw that there are 8 possible 5th gears on http://brokevw.com/020ratios.html so my question is if I currently have a .805 5th gear how tall a gear could I go to without having the 4th to 5th shift be totally unbearable? I have seen that .75 conversion is very popular but I am very curious about the .71 as this would be a way for me to get some MPG's back that I will likely be losing as my car is going to be turbo'd in the next 1000 miles. Small Saab 95 turbo to start but I would like to do my research and make sure that whatever I do will be reliable.
I'm a bit of a novice when it comes to transmissions so bear with me if my questions seem stupid.
Atleast 17,000 to 20,000 miles, providing there are no leaks, and it depends on how you drive. Grandma type driving is ok at this mileage to extend trans life, my type of driving, drags here and there, car club runs, 150 mph here and there, definately change it then.
Trust me better to ask questions than saying, dam I should have asked... we are all learning still.
I would run the .75, reason being, the ring and pinion is a 3.67. The .71 or 2 might be a big drop off in rpm, power like this , Blaaaaaahhhhh 4th gear, shift to fifth Bloooooooooohhhhhh, big rpm drop in the shift.
But some people like that though. Try a .75, if you are happy leave it, if not a .71 might be good for you.
Better you check the linkages first or cables if its an 02J/A trans. See if there are anything in the way like hoses, etc. Check the bushings on the shifter, etc. Disconnect the linkages or cables at the selectoer shaft. Then try to engage the gears by hand to see if its still hard to go in.
Hey HGB I have a question that was answered with many different responses...
I have an 03 Jetta 1.8T EHA 02J 5-speed.
Normal driving shifts good, but at higher rpms (3500+) there can be difficulty in shifting.
Especially in first gear, but it happens in 2nd and 3rd as well (haven't gone fast enough to know about 4th) the transmission doesn't want to come out of gear, I have to yank on the shifter to get it out of gear (have only done a few times) or I have to wait for the revs to drop until it will come out of gear. I can however get it out of gear if I time it perfect with pushing in the clutch without any extra force. But mostly in 3rd and 4th shifting into those gears at higher rpms it will grind, and sometimes will deny access getting into gear. Also sometimes I'll have the clutch pushed in and right before it goes all the way into gear it won't grind but will "bounce" the shifter as though I've let off the clutch a bit but it's to the floor.
I can still daily drive my car without issues, but it's annoying to know I need this fixed before I even think about a tune or upgrading. Any help would be greatly appreciated
Yes, they can be swapped over, pull the entire selector shaft out and transfer it to the other trans.
Compare the height on both shafts, if the height is different, also remove the VW embled lower support and swap that over.
If the lower support on the 02J trans has a clip on it, discard the clip and install the flange...more on that later on.
If you are putting the 02A in a car that has the 02J trans, remember there is no spot for the dog bone mount.

Ok, this sounds like the clutch is not fully disengaging. Try to bleed the clutch master and slave cylinder first and see if that solve the problem.
Synchros can cause grinding if they are cracked or worn, but I dont think this is the case with your trans.
The other thing is gear oil level and type.
Other thing I have been finding on 02Js is the clip on the lower support of the selector shaft, it will cause jamming, etc... more on that later.
I just changed the fluid in the trans <5k miles ago. I used some Valvoline 75w90, nothing special was free. I plan to put some MT90 in it when I feel like pulling the trigger on the fluid and a funnel that's long enough...
And which clip are you talking about exactly? I had my shift linkage adjusted here at the dealer when I bought the car last August and that definitely helped a lot. I had to put it into gear at an angle instead of straight on.
BUMP for my man HGB!! dude is the best! i'm still saving up for one of your custom geared trans and a diff! sorry missed show n go...we gotta do waterfest--i think i can get ya a pass again! chat soon bud.
So I'm going to bleed my clutch again and check the master cylinder for leaking. Then I'm taking the shift boot and console off and having a look up under there and adjusting my shift linkage again. Maybe buy new ends with bushings.
Then I'm getting a VR6 clutch with G60 flywheel, because it'll be nice to do even if it isn't the problem, but if it is. Win-win-win
I just finish a Transmission swap on my Scirocco 16v I installed a mk3 020, all my gears work fine except reverse, when I pull the clutch it sounds like its going to exploded, is there any special adjustment or trick for this transmission? Any help would be appreciated thanks.
My brother and I just bought 96 golfs. His is gti vr6, mine is 4 door gl. Both have an issue sometimes with going into first gear. Sometimes it works perfect, other times it won't go into gear. At that point you have to shift into 2nd then up to 1st. Sometimes it goes first try. Sometimes it takes 2 or 3 times. Any ideas?

Disconnect the linkages rom the selector shaft, try to move it to neutral, standing in from of the car, turn the selector arm slightly to the left, this should neutral.
If it move to neutral ok, put it back in reverse, press the clutch, start it slowly let out the pedal and observe what happens.
Try to use the selector shaft arm from the scirocco as they might be different om the MK3 trans.
02a goes in all gears but still moves like its in neutral manualy put it in reverse and all gears i hear the clicking.. but when i let off the clutch.. it does nothing ?
i checked the clutch master and its in working condition..

Its possible there could be diff issues, check your axles also first. Lets say you put it in gear start it up, have someone slowly let the clutch out and observe the axle flange and axles, on jack stands. Or if the clutch is really worn it can do the same thing.
