TH350 Slipping???
Hey guys, I have a TH350 behind a 400 small block in my 72. It feels like the tourqe converter isnt working correctly, but i have to give it some gas to make it move forward or backward. almost like i have a clutch and im letting it off slowly. Just wondered if you had some advice for me. Thank you in advance.

Havent actually had it on the road yet, have taken it down the pasture road and seems to shift up and then immediately shift back down.

Re: TH350 Slipping???
What speeds on the pasture road? May need to get in the service manual and follow the pressure check sequence. It may have a stall converter you don't know about possibly.

Re: TH350 Slipping???
Speedo said 30~ very well could be a stall converter. Will follow pressure check procedure.
