Knew I Shouldn't Have Bought An Auto...

[BridgeyBoy]

Hi all
First post on here..

Just bought a 52 plate 1.9 TDi Auto with a slight gearbox problem (well I hope its slight!)

Was driving normally but it has started to occasionally stick in 1st gear and refuses to change up. After stopping, switching on/off this seems to clear it but it is still doing it occasionally. Any thoughts?

Cheers

Dave

I dont have any thoughts, except that doesnt sound too bad... switch off and on to rectify suggests it'll be an easy fix.... do please let us know because I'm a believer in Autos and twould be useful for others

It would be worth looking at the fluid level if nothing else (the condition of the fluid while your at it wouldn't be a bad idea to check). Theres some info here from the faq section

might also be worth a look with vcds lite if you have a lead to see if any faults are being logged?

Don't dis the gearbox straight away, these boxes rely on input from the engine ecu, if the engines going into limp mode this will also affect gear changes.

Scan your car for fault codes and see what's occurring.

Hi Dave,

I recently watched a Wheeler dealers where they had a Range Rover with an auto box that was sticking through the gears,all they did was drain the auto box fluid and replace with new oil and clean the strainer.The old oil was really nasty and this cured the problem.

Hope this helps and I would check this first.

Have you scanned the gear box ECU  with VAG-COM? That's best before you move on with looking for the concern - it might only be a sensor ... stuck in first can be many things the AG5 box you have has a couple of weak spots BUT installed in the Galaxy - there are some traps that can get people caught out that "make" them change or overhaul the box for the wrong reasons.

 

Scan first then report back.

 

Regards,

The cabling to the auto box has been known to chaff through where it passes over various metal surfaces causing shorts and making the gearbox ecu go into limp home mode. Check the wiring for any evidence of wear.

 

Limp home mode for the auto box is normally 3rd gear selected.

Thanks all..

Realised the issue was only from cold. Allowing the car to idle for 5 mins before moving off seemed to do the trick.

Decided to change the gearbox oil as a starter for ten. Used the info on here and two hours later job was done. Took it for a test drive and works perfectly even from cold. So far, I'm a happy man. Need to give it a good run but did 5 mile test in it and changing was fine. I used Dextron 3 spec fluid. Only drained and filled once so I know it will not be clear yet as it only took about 3.5 litres but now has to be better than the black tar that came out!!

Anyway, thanks again for the advice.

Just need to fix that alternator tensioner now.... Judder, judder, judder!!!
