Post by: chuckie3225 on September 03, 2015, 08:47:00 pm

77 K10 with 350SB coupled to TH350. When I put the truck in reverse is moves just fine under the truck own power idling but if I give it throttle the RPMs just climb with little output from trans. also I just noticed that it's not shifting into third..  ready ..set...goo.

Third and reverse use the same clutch pack, which may very well be burned out in your trans.

I actually just finished rebuilding a TH350 where that was the case.
