1st time engine swap. Drove 01Runner into garage. Vehicle was left in neutral w/ E brake on. Engine cranked by hand no problem. Removed old engine. Replaced TB & water pump on donor vehicle engine cranked by hand no problem. Installed donor engine into runner. Turned crank to align machined key slots in Torque Convert and slid into postion. Tightened all bolts on tranny. Put all parts back together. Tried to crank by hand and won't budge. Check to see if its in neutral
still won't turn. I can push the car in neutral. I am lost as to why it won't turn. Any ideas appreciated.
