th350 wont drive truck. forward reverse.. nothin. pulled a line off cooler and plenty of fluid is coming out so the pump is fine. any other tests i can do before i pull it? thanks

You may have snapped the mainshaft. I did it in my Blazer with 38 in tires. I upgraded to a TH400 and it never happened again.

try putting the transfer case in gear.

I went through about 4 th350 with my K5 on 38.5" swampers. Never though much about it just went and rebuilt them and went on with it.

that's exactly what it seems like. i was all ready to pull it out but i gave it one last test and all of a sudden it started working again. it didn't last long though. is the tranny toast? thanks

yup time to pull it. everyone of mine would burn up forward gears and would at least leave me reverse to get out of the trails. It was hard but I made it (Most of the time)
