Hey I have a 1994 auto 4x4 IDI stock turbo truck I dont no fer sure what kind of trans it is but it does have the over drive on the shifter and I think its a E4OD The problem is that it dont shift right you have to let off the gas just a hair so it will shift and the overdrive light blinks on and off the whole time but It will go out of overdrive if you hit the button. I was wondering if anyone can help me out thanks
