Transmission fluid/issues..?

[mik15]

it is the same fluid but of course with a different part number, here is the list for the same fluid used by different car manufacturers:

ZF Lifeguardfluid 5 (ZF No. S671 090 170)
=> Audi / VW Oil No. G 052162 A1 / A2 / A6
=> BMW Oil No. 8322 9407807
=> Citroen Oil No. Z 000169756
=> Jaguar Oil No. JLM 20238
=> Mercedes Benz Oil No. A 0019892203
=> Peugeot Oil No. Z 000169756
=> Porsche Oil No. 999.917.547.00

The problem was the missing O-ring. I would never trade the shaeffer's for the vw/audi fluid. Synthetic>mineral.

Just for conversations sake, could there potentially be more clutch slip with synthetic than with mineral?

Interesting that you bring that up, I had wondered the same thing, and that is one of the reasons I decided to switch back to the OE fluid (besides getting a more complete fluid change).

It turns out that my transmission is not actually back to 100%... I functions great except for one thing: under hard acceleration, the 1st-to-2nd shift is screwy. It pulls hard through 1st, starts to shift normally and bring the RPM's down as it goes into 2nd, and then it's like the TC gives up and the RPM's jump back up to redline and it feels like the car is just coasting for a bit, then the TC starts to grab again and it lurches into 2nd, not super hard but definitely harder than it should. I'm going to check the fluid level later today, but I'm very sure that there's the right amount of fluid in there. I'll report back once I know if the level is my issue..

For the record, it shifts great from 2nd to 3rd, 3rd to 4th, and 4th to 5th under hard throttle.

What you describe has nothing to do with the TQ. I encourage you and anyone reading this tread to take a 1/2 hr out of their day and head to YouTube and look up some videos describing the basics of what a TQ does - including what a lock-up convertor does. You will quickly set aside many misconceptions people believe are occuring with their rides as being TQ related concerns.

Like the others said, it is not the TC. If it was the TC, it would do it in higher gears more. One you pass the 1800 stall speed it locks up. Your second gear is going.
