Question

recently had tranny rebuilt, changed the input speed sensor., when I connect the output speed sensor rpm goes high. this code came up after all this was done. What else could it be?

Answer 1

The existence of DTC P1790 indicates mechanical or hydraulic (not electrical) related problems. It should be noted, however, that all mechanical problems don't necessarily result in DTC P1790. When this DTC exists, diagnosing the system should be based on the associated DTC and only mechanical causes should be considered.
