Hello all,

 

My automatic transmission in my 84 GL hatchback is not shifting gears when in drive. I can manually shift them from first to second with the shifter but it will not do it on it's own in drive. I have it at a transmission shop and they said they tried replacing the modular and checking for the compression (which was fine) but it still is resisting. Would anyone know what is wrong? Or would someone know where I can look for a transmission for the car and what are some interchangeable transmissions.

Sounds like the governor gear to me.

Where can I get a governor gear?

That I'm not sure, I haven't had to deal with a bad one in a very long time.
