1990k15004x4
Newbie
I have a 1990 k1500 I’m doing a restore on. I got the engine running (350) I pulled a 700R4 out of my 91 k1500 that I had rebuilt recently. I fired the truck up put it in gear and nothing truck doesn’t move in any gear. I put it in all gears and tried pushing the truck and everything acted like it should. I have checked everything multiple times now. I did pull the transmission lines to see if fluid was pumping and nothing came out. Anyone have any ideas?
