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 5th gear ratio, it is detected as a malfunction of the hydraulic circuit or the 5th clutch. The actual gear ratio must match one of these conditions for at least 12 seconds with the 5th gear command. Actual gear ratio is greater than the 5th gear ratio by a factor of 1.2 Actual gear ratio is less than the 5th gear ratio by a factor of 0.75 NOTE: Before you troubleshoot, record all freeze data and any on-board snapshot
