Just bought this truck a couple weeks ago most of it seemed fine to the naked eye some cosmetic problems, door locks, muffler, and power steering pump, and some other minors. however i was doing some light 4x4 in our back lakes aria and thew truck shut off ue to over heating. let it cool down put some water and coolant in it and got it home. replaced radiator, top and bottom hoses, thermostat, and then found out the leak was the water pump. replaced and problem solved... however now when in drive reverse or any other gear that makes the vehicle move, it does not. maybe an inch or two. its almost like trying to drive with the e brake on. yes i have checked that, also changed tranny fluid and filter. I am at a loss and have put all the money i have into this and am missing out on work. is there anyone who can help me with this? again its a 96 Z71
