Problem in 2nd Clutch and 2nd Clutch Hydraulic Circuit (2nd gear incorrect ratio)
Problem in 2nd Clutch and 2nd Clutch Hydraulic Circuit (2nd 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 2nd gear ratio, it is detected as a malfunction of the hydraulic circuit or the 2nd clutch. The actual gear ratio must match one of these conditions for at least 12 seconds with the 2nd gear command. Actual gear ratio is greater than the 2nd gear ratio by a factor of 1.2. Actual gear ratio is less than the 2nd gear ratio by a factor of 0.75. NOTE: Before you troubleshoot, record all freeze data and any on-board snapshot.
Cause and Solution
Low or dirty transmission fluid
Faulty shift valves A, B and C
Faulty ATF pump and the regulator valve
Inspect the strainer for metal debris or excessive clutch material, if present
