Hey I just bought an automatic 95 GT but it doesn't shift gears correctly I had a friend from a transmission shop check it out and they replaced the tranny but the issue slowly reappeared... Took it back n he said that it the tranny isnt causing the issue... He suggested a computer or wiring issue .. Ne one have any suggestions as to what to check or how to fix the issue? The exact issue is. The gears lag to change; gears rev too high and won't shift on time or sometimes not until I let off the accelerator......if I.don't let off the gas the gears slam in an jerk the whole car .. also the check engine light comes on and I recently realized that the odometer doesn't work :/ ... It's my first car and I'm hoping to keep It for a.long time or until I can learn to drive stick and switch to a 5spd.. N e help would be appreciated thank u ..
