Hi guys ,
I put the wrong friggin lubegard in my recently acquired 2004 Jetta with the 01m transmission. The original fluid had never been serviced, so I serviced it, and accidentally put lubegard black in with Mobil 3309. Mobil 3309 is already an ATF+4 with HFM, so lubegard black which adds more HFM wasn't the right additive. I only added roughly one ounce per quart though. This car has 120K miles, and I suspect the valve body is starting to go out as demonstrated by hard shifts.
So it's extra slippery in there for sure. I do slip going up hills, but not any where else but it could have been doing that before. The slip is rev up the hill->downshift as expected->back to upshift immediately. Is slipping a function of the valve body or the transmission itself, or both?
