1983 Chevrolet S10 Base 4 Cyl 1.9L - Transmissions & Drivetrains
My 83 Chevy truck shifts stiffly after changing the transmission
I've got an 83 Chevy truck with a 305 and I just did a transmission swap for a 350 tubro, the guy who had the truck before me put in a different th350, but the truck originally had a 700r4 and now I can't get it to shift right I've been playing with the vacum lines and replacing the old bad ones, but it stiff shifts into 2nd around 50mph and 3rd at 65.

    I would check for clearance around the shift cable and make sure it's routed correctly. Also make sure you have the right A/T fluid in it. Not sure if this applies to your transmission but if it has a transmission range sensor than that could also be the problem. Good luck, let me know what it was when you find out!
