Okay well i blew my car up yesterday and went on the hunt for a car and i found a late 90's ford explorer for pretty much free.A buddy had ran into motor problems and had replaced the motor and the transmission for 900 from a salvage yard.I watched him work on it and when it came down to it the truck fired right up but heres the problem once u put the car in drive or put a load on the motor it like stalls out n just turns off?He also isnt to familiar with transmissions but had mounted this one so im thinking its something simple that he cld have missed or maybe a sensor?Idk..If any one has ideas to what it cld be have no hessitation and lmk your opinions...thanks
