Installed new Chip, no longer shifts
The other day I installed a new chip, the chip was to reduce the engine temp. Since I installed the new chip, the auto trans will not shift from 1st to 2nd. I went back to the stock chip and still have the same problem.
Any thoughts?

Re: Installed new Chip, no longer shifts (85shark)
Welcome to CF. The 85s dont use the PROM for shifting. All it does is engage the torque converter. Sounds like you have a coincidencedental tranny problem. You may want to post this on the tech/performance section to get more suggestions.
