jasongtr Posted April 24, 2011 Report Posted April 24, 2011 i have posted up for a few months on a few posts about how my gearbox seems like its giving up, after travelling to norfolk this weekend it got a little worse, going there it was ok, although after a few dodgy 2-3 and 3-4 changes (with squeeks and squeals) the management light came on the next day, now i have vag com and can clear the fault, but coming back this afternoon, after about 30 miles it wouldnt go into 4th, and from 2nd to 3rd it wold only change at 4k revs still with a light throttle, it would only go as high as 3rd (but would go from 1st to 2nd and 2nd to 3rd still - so not in limp home mode) for about 45 miles, so we stopped to get a bite to eat for 30-40mins and continued, all was fine again, still a few squeeks and squeals on occassion but with light throttle would change through all the gears at 2k or less revs. so whats the price of a recon box fitted, or would a simple oil change do any good - needs to be a high chance of success for the oil change though, and whats the cost of that likely to be, ive been advised it needs to be done by a garage as it needs to be added at the correct temp, so a home on the driveway gearbox oil change is out of the question.

chrispb123456 Posted April 24, 2011 Report Posted April 24, 2011 If you do want to go the route of doing it yourself you will need Vagcom lead to get the correct temperature as this is quite critical, you can also check if there are any fault codes stored.As its impossible to drain all the fluid in one go you would need to change it two or three times with a drive between changes to get the fluid looking a reasonable colour the five speed box's filter is not possible to change without stripping box, the four speed the sump pan can be removed and filter changed but still not possible to get all fluid out as the torque converter and valve chest do not drain.Do the search for checking levels depending on which box you have.There is a filler cap a drain plug and a level plug, be sure you have the correct one (level plug) Quote
jasongtr Posted April 25, 2011 Author Report Posted April 25, 2011 these are the fault codes that were stored - its a 4 speed auto Address 02: Auto Trans Labels: NoneControl Module Part Number: 099 927 733 AP Component and/or Version: AG4 Getriebe 099 4773 Software Coding: 00000 Work Shop Code: WSC 00000 VCID: 72E1204214294 Faults Found: 00518 - Throttle Position Sensor (G69) 16-10 - Signal Outside Specifications - Intermittent00652 - Gear Monitoring 27-10 - Implausible Signal - Intermittent00638 - Engine/Transmission Electrical Connection 2 03-10 - No Signal - Intermittent01192 - Torque Converter Lock-Up Clutch 04-00 - Mechanical Malfunction still not sure about the temperature being correct/critical, every other post i have read suggests running the car for about 5 mins - that doesnt sound very accurate if its supposed to be critical Quote
chrispb123456 Posted April 25, 2011 Report Posted April 25, 2011 Make a note of those fault codes ,then clear them go for a drive see what comes back,seems like you may have some wiring/connection problems.Having to much or not enough fluid will create it's own problems, how can you say run engine for 5 mins, this is going to vary so much between different engines and the ambient temperature.The recommended temperature range for the fluid is 35 to 45 deg c you have access to VCDS so whats the problem.

jasongtr Posted April 25, 2011 Author Report Posted April 25, 2011 (edited) the problem being i cannot work out how to access the auto fluid temp part in the software, if you can talk me through it that would be great. the faults that came up i think are the same as what came up before, i cleared them last time and after a few miles the management light went out and on rechecking the fault codes they didnt come back until i had the problem yesterday. if i can do the gearbox oil myself with a few pointers on how to run the temp up using vagcom then ill do it myself from what i can tell ill need the oil obviously - enough to do it 2 or three times, and a new filter (in the sump i believe) and i guess some new gasket(s) or sealant for when i refit the sump, im guessing that the 2nd and possibly third time i drop the fluids i wont need to take the sump off, wont the first time be enough for that. thanks for your help thus far, if i can get the vagcom info ill do it this week as we are off for a 400 mile round trip on holiday in a few weeks, if its not done by then ill be hiring a car to go away in Edited April 25, 2011 by jasongtr Quote
