Golf iV TDI manual transmission oil change

Questions pertaining to a VW Golf Mod4 TDI 1.9L engine MANUAL TRANSMISSION OIL:

1) What is the capacity? 4.3 pints

2) What is the specification? (Am planning to replace with AmsOil.) AmsOil 75W-90

3) Manual infers a 100K change interval; is that okay? probably

4) MAIN QUESTION: What is the procedure to replace the maual transmission oil? (I know there is a plug to be checked for fluid level every 6K mile.) http://www.myturbodiesel.com/1000q/a4/manual-transmission-gear-oil-change-Jetta-Golf.htm

There is a drain plug at the very bottom. Don't know about the fill plug as I haven't dealt with that yet but it should be easy to find. Looks like you will need to buy 4.3 litters of oil. This is the amsoil website listing the correct oil and capacity.

Drain out the bottom, fill from the side plug. Both are 17mm hex's. Fill until it starts pouring out (on level ground). Should be a little less than 2L as you won't be able to get everything out.

Here's a thread with info on different oils, I run Redline and am happy with it btw. http://forums.tdiclub.com/showthread.php?t=132884

If you want, here's a nice write-up: http://www.myturbodiesel.com/1000q_how_to/a4/mantrans_oilservice.htm

Good luck.

To find the inlet to the manuel trans:
1. Remove the engine cover (that's to make life easier).

2.On the right front side near the base of the transmission you will see screw plug staring up at you. This is the access to open and fill the trans.

3. The drain plug calls for removing the engine belly plate. Toward the rear of the trans near the axle shaft you will see the drain plug.

When I drained and filled my 2000 jetta I do not recall using 4 liters of trans oil. I vaguely recall using 2 liters. I bought some upgraded oil from Bora, (Vender) here in tdiclub. (It really increased my mpg by 3 miles in 4th gear. A blown 5th gear. That is another story that takes too long.)

It really is an easy job

2 liters - get the VW G60 gear oil (replaces the old G52) - the dealer near me matched the World Impex price...and yours may if you ask nice..

I change mine every 8 years...in another 8 years the VW oil will be up to G90 or something...

I suggest some high temperature [removable] thread sealer for the plugs. My plugs seep a little and I will use sealant next time.

I did this research on my 1997 Cabrio and found out that it is filled with 2 quarts or 2 liters of synthetic. I've decided to let it be.

For manual transmissions/transaxles and stand-alone differentials, I think you're better off to never check them at the fill plug unless you see leakage. Otherwise, you run the risk of introducing some grit. You also run the risk of putting the wrong fluid in there. Been there done that.

On our 1983 240D, its transmission and differential got changed twice in its life (so far with me; new owner now) when one of the seals on them started slinging fluid. Changing fluid stopped the slinging. Same thing for the power steering pump.

Unless you're going for extreme life, I'd consider them sealed for life.

There is plenty of cases of people who have blown their 5th gear by not checking their trans fluid and letting it get too low.

Never checking it at all is probably the worst thing you can do IMO.

My 99.5 shifted MUCH better after I changed it's fluid.

Despite the popular myth that transmissions are sealed for life, they are in fact NOT.

+1 on the checking of the fluid and a little RTV on the threads of the plugs never hurt no one.
