power surge
Purchased this truck with a bad transmission and had the transmission rebuilt.
Truck surges around 35mph (coast and go) Like maybe shifting back and forth between gears. There are no trouble codes showing up. Motor seems to run fine otherwise so don't think it is in motor. maybe something wrong with rebuilt trans. Can a speed sensor cause this, is an abs speed sensor and speed sensor the same thing just different vehicles.
Thanks for any help I can get
