Hey everyone, I'm having major issues that i cant seem to narrow down. I'm currently rebuilding my f22b1 and i have an auto trans about three months ago i went to go out and my trans when cold shifted fine and once it got warm i was at a light and took off and it shifted back forth real quickly, and seemed to lock in 2nd. It always does this now once warm wont shift or go past 45mph, I cleaned the lock up and shift solenoid also checked ohms they both are at 25.2 i was told that its ok even though it says between 12-24ohms. I'm wondering maybe the speed sensors or TCU i changed it out on a good one and it still did. Im lost prob should mention before this problem happen, the night before it was misfiring bad needed new wires havent tried it since that day, wondering if a new trans is needed.

 

This one question will take some research... Welcome to the HAF!

 

also, once warm to it wont even let me manually shift either, seems like in lock mode

 

Be sure engine is running good. A problem there can steer you to think it's atrany issue. check shift cable on trans. More info would help too.

 

more info? what do you need to know? thanks for the help this is driving me crazy!!!!!!!!

 

Have you checked for TCU codes? Read how to get CEL codes thread in the DIY section. For transmission codes, count the D4 or the S light flashes. Post any codes you find on here.
