I just got my transmisson back from the tranny shop. I have a 442 Olds its a KZF on the ID tag. Question is that my 2-1 downshifts almost never happen. He says its my governor so I got one from CK performance. Is this true or can it be something else? I had him do everything he could to BULLETPROOF this thing. He had assured me he has done many and the governor is the Culprit. ALSO when I got the governor I expeccted only on spring in it but it came with two should I leave the two in there? I had taken the old one out before and it only had one spring what gives.
