: 96 Fleetwood - Soft 1-2 shift and Climate control diagnostics not working

08-14-11, 04:55 PM
I have a 96 Fleetwood with 130K.

It has been shifting extremely soft only on 1-2 shift.

It also displays -- when trying to pull PCM codes through the climate controls. All others read codes as they should. It will give the codes when using a code scanner.

I have checked the ground on the head. Replaced the PCM and did the ground update. Still no dice. I have had it at 2 transmission shops and spent a lot of cash just throwing parts at it. Parts replaced - added corvette servo, reman valve body, shift kit, PCM and the ground fix.

Anyone have any other Ideas? I'm about to start selling parts off a car I love. :(
