I pulled my 22re engine and put another one in and everything seems to be running fine accept my yota wont go into 4 wheel drive. I didnt pull the transmission and the only thing i can think of that there was a wire connection going to the front axel and i double checked that it was plugged in and the 4 wheel drive was working fine before the old motor blew up and now since the new one is in iits out. any ideas????
