Tranny question
 

Hey Guys I'm new here and figured I should say hello first. I own a 88 Mustang LX with the 2.3 that I just swapped a month ago for another, less mileage and no knocking, motor. I now have a weird trans problems among some other gremlins. In the morning after start up the trans will not shift out of 1st unless I pull the shifter down into 2nd. Then it will not shift from 2nd to 3rd until I drive for about a mile or two in 2nd. If I try to manually shift it to 3rd it almost feels like it goes back to first but really feels more like it just slips. After a mile or two I can shift it into 3rd and all is well. Trans will shift normally until you turn the car off and let it sit for a few hours. Any ideas?

I'm not certain if these transmissions use a vacuum line or not. It sounds like symtoms of a leaking vacuum line to me. Look for a line running from the transmission to the intake manifold or the tree mounted on the firewall.

Thanks teach. It does have a line from the modulator to the vacuum tree. I am hoping that is the culprit also. About an hour ago I replaced the small amount of rubber vacuum line because it seemed swollen. Find out tomorrow if it worked.

Vacuum didn't fix it. Was told by someone that dirt in the governer causes this but needs to be rebuilt to cure. That's like $1000 and I don't think the whole car is worth it. Might just have to live with the problem.
