P1790, P0700, and P0733 codes on a Dodge Neon SXT, what does it mean?

Question

The car is automatic and will not shift above 2 gear (can only go up to 30 mph). We have replaced the Transmission Speed Sensor (Input and Output). Also replaced the transmission control module. Neither had any effect.

P1790, P0700, and P0733 are all the codes appearing.

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.
