P0733
Definition:
Problem in 3rd Clutch and 3rd Clutch Hydraulic Circuit (3rd gear incorrect ratio)
Description:
The powertrain control module (PCM) computes the ratio of the input shaft (mainshaft) speed to the output shaft (countershaft) speed. When the ratio is not the 3rd gear ratio, it is detected as a malfunction of the hydraulic circuit or the 3rd clutch. The actual gear ratio must match one of these conditions for at least 12 seconds with the 3rd gear command. Actual gear ratio is greater than the 3rd gear ratio by a factor of 1.2. Actual gear ratio is less than the 3rd gear ratio by a factor of 0.75. NOTE: Before you troubleshoot, record all freeze data and any on-board snapshot.
Cause:
Low or dirty transmission fluid
Faulty shift valves A, B, and C are stuck
Faulty ATF pump and the regulator valve
Inspect the strainer for metal debris or excessive clutch material, if present
replace the transmission
