Re: the gears are slipping on my 1.9 tdi auto passat ??
This procedure is not recommended, first of all it is not gear oil. it is automatic transmission fluid. this is why VW has made it difficult for the incorrect fluid being added. also the fluid is added from the bottom of the transmission and is only added if the transmission is at a certain temperature.

Unfortunately this is not uncommon and I hate to tell people bad news but the problem is in the transmission. It sounds like the reverse is not locking in like it should. There is a pin inside the transmission that is supposed to lock it in place when you shift to reverse but that may have rounded off or seared off which would cause your problem. A clogged filter will also cause this issue. If you had that transmission back flushed, the normal method used today by shops that cost around $140 or so, then I can tell you for a fact that it needs to be rebuilt.
STOP the engine immediately !!! There is an oil pump failure of 2.0 TDI engines ! Remove the oil pan and the oil pump & balancer shafts assembly.
Either the shaft driving the pump from the balance shaft rounds off or the balance shaft drive gears eat themselves. The same issue ... low oil pressure warning light, noisy rattling engine, and the turbo has gone. Diagnosis: oil pump balancer shaft assembly ...
Many Passat show excess chain noise and wear anywhere from 50,000-100,000+ miles. Cars have broken the chains/tensioner as low as 65,000 miles. This is just a range of cars that have been reported, diagnosed, and repaired. The actual statistics on dealer repairs or failures is unknown and I've heard cars over 100,000 miles that, in my opinion as a non mechanic (most mechanics wouldn't recognize this sound and problem either), aren't noisy. From what has been reported, noticeable noise/chain-tensioner wear/greater risk of breaking is around 60,000-150,000 miles. Your case may vary. The most obvious symptom is a rattling loose noise from the oil pan. Unless you listen to a Passat TDI with a tight chain and one with a loose chain, it's hard to describe the difference other than rattling chain noise. The reason the gear drive oil pump modification was started is because a few mechanics who specialize in TDI have seen many worn oil pump chains/sprockets/tensioners. There will always be a few defective parts that come off the assembly line and all mechanical components like chains wear out sooner or later, but in my opinion, the failure rate is abnormal considering the number of Passat TDI sold versus the number of reported oil pump failures. This does not necessarily mean that every or even most Passat TDI will have this problem, just that the reported failure rate is high enough to consider this part a design failure. Nobody, not even VW-Audi knows the average time between failure for these parts and the percentage of cars that will have this problem, but they changed this design and if you want to not have this specific failure, the only sure way is to swap to the geared module.
Hi Craig, I'd suggest that the oil seal which seals between the torque converter neck and the gear box casing is damaged and will need replacing. The job seems simple but in fact can result in breaking the gearbox oil pump, when the torque converter is refitted to the gear box. the neck has to align with the gears inside the gear box and the oil pump, if the torque converter is not fitted correctly the damage I've mentioned will take place when refitting box. If you would like to proceed let me know. Regards Johngee10
Dose the clutch pedal drive in gear 1" from the floor OR 1"" from the top when you let it out. if its drives when almost out and there is a vibration on the pedal then the clutch needs replacing and it has nothing to do with the gear box or oil
But the gearbox has to come out before you put a new complete clutch in
