Recently my trans just got stuck in first gear i noticed that the wiring harness was melted on the exaust maniflod so i fixed and recovered all the wires but still would not shift out of first for a couple of days and one morning it just shifted like normal and then wouldnt shift back into first and even manually shifting wont help and there is a noise when i put into park ,if i manually shift it only goes to second and then third and then my check light comes on . Can anybody help with this

 

You have a governor that is sticking. The plug on transmission is just for the lock up converter.

 

Can u please tell me a lil bit about the governor ?its a shame that im a mechanic by trade but for some reason have never really fooled with transmissions except for pulling and replacing .what kind of a job is it getn to the governor ,and if the wires were burnt and grounded out to the manifold could that have done something internal

 

Watch this video. It will walk you through the process.

 

About the only thing that would be effected would be the lock up solenoid. Won't cause shifting issues. If bad or not working you will notice RPMs a little higher at highway speed.
