I installed a PTC 10" 3,000 stall converter to replace my stock D5, I also did a fluid/filter change at the same time. The fluid I used was Dexron VI Fully Synthetic, the trany has under 50,000 original miles on it. Every thing was fine and acted normal until I put on a few hundred miles, then I noticed that the trany didn't shift as firm as it used to. It actually shifts like it doesn't have a shift kit , like it did before I had a Art Carr shift kit installed years ago. So after some searching I came up with two possiable reasons:
1) I read that a higher stall converter can make the trany shift softer, I don't think this is my issue because after the install the trany shifted like it did before the swap. Since this is my first TR and my first experiance with a higher stall converter and I don't have anything to compare it too so I am not sure.
2) Some say that switching over to Dexron VI Fully Syntheyic could cause the issue, if so can I drain the trany pan and add Type F fluid to get my crisp shifts back. Is Type F trany fluid compatiable with Dexron VI ?
What do you guys think.Thanks ,Kyle.
