I had my mechanic install the ck performanc shift kit. A.J. owns a performance and pcm calibration shop and retired as the head tech for the local GM dealership. So he is very knowledgeable but can't say he's a 200R4 expert or turbo buick expert.
He install the kit per the instructions. When he completed the work, he said it shifted well and very firm as I would expect. But when drove it, the shifts were very soft. So soft it was hard to tell when it shifted gears. And from a standing start at full throttle it will not shift out of first. He drove it and confirmed it's not shifting firm like it did when he drove it.
So he has it back in his shop.
Any ideas from you guys what is the likely problem?
