The P0734 code implies that something uncommon has been detected by the power-train control module (PCM) with the forth gear ratio in the transmission of the vehicle. Usually this will have to occur several times before storing a problem code. P0734 - GM; Type: Powertrain - Transmission - ISO/SAE Controlled: Description: Transaxle - No Fourth Gear Conditions. Cause: No Speed Shaft, Noise or VSS codes set, VSS input over 3 mph, TSS over 224 rpm, high line pressure commanded, then the PCM detected, 2 times per ignition cycle, that the ratio failure counter equaled 255 at steady state, or that the shift counter was over 100 during a.
– Incorrect transmission shifting
This diagnosis monitors actual gear position by checking the torque converter slip ratio calculated by Transmission Control Module (TCM) as follows:

A: Output shaft revolution signal from revolution sensor
B: Engine speed signal from Engine Control Module (ECM)

C: Gear ratio determined as gear position which TCM supposes
If the actual gear position is higher than the position (4th) supposed by TCM, the slip ratio will be more than normal. In case the ratio exceeds the specified value, TCM judges this diagnosis malfunction.
