TH350 shifting troubles

Caeadiel · Oct 13, 2024

After getting the transfer case issue figured out(grinding going into park, needed gaskets replaced and fluid topped off), I am now having issues shifting. Sometimes shifting from park to reverse it will go, with a clunk, but sometimes I’ll need to shift to drive, then try shifting back to reverse and it’ll engage, again with a clunk. Sometimes I’ll have to keep trying to get it to go. While driving there are no issues with it shifting from 1st to 2nd and so on. Just want to know what would be the fix here? Rebuild trans or what? I did check the fluid level and it looked fine.

Check your external shift linkage for anything loose, etc. If nothing out of the ordinary is observed, drop the pan and see if you have a bunch of burnt clutch material at the bottom...If so, it's likely the remains of your low reverse clutch pack. Trans would have to come out for overhaul.
