When i put the car in drive and let of the brake the car goes no were it just sits there, and if you press the gas down it just revs. i think the ecu is senseing it is in neutral but i am not sure can anyone help me i need help asap i dont have a car now


-thanks Robert

 

it might not be an ecu problem but a pressure problem in the transmission. What could be happening is there is no pressure building up in the transmission, so the pistons dont engageto driveyour input sun gear, and your output carrior is not being held. What you should do is have the transmission pump checked to see if it is at least moveing fluid. If that checks out fine then what you should check next is the friction and steel plates that hold and drive your planetary gears, they could be worn down so much that even with pressure applied to them from the piston they dont have enough material to grab on to.
