I installed a 1996 motor into a 99 blazer. All went well but the truck will not go out of 1st gear and the speed gage will not move. Motor will rev normally when pushing pedal but you can not feel anything trying to kick into a higher gear. Same results in Drive and lower gears for tow. Reverse works. Fluids are fine. Instrument panel works. A check engine light will come on after the truck gets hot. Codes PO-107 manifold pressure and PO-1345 Cam shaft sensor. But how is the speed gage and transmission related together? The transmission senses the motor reving and telling the transmission to go into higher gear but it's not happening. Why and where and what do I check? Mechanical or Electrical?
have the same problem?
