Road Test

This test will verify that the governor pressure and shift control valves are operating properly.

1. Bring engine and transaxle up to normal operating temperature. Place transaxle in Overdrive. Check upshifts at minimum throttle. Note upshift speeds and speed at which converter clutch applies. Refer to appropriateSHIFT SPEEDS  table in this article.
2. Place transaxle in Drive and repeat Step 1). Transaxle should make all upshifts except 3-4 and converter clutch should apply above 27 MPH.
3. Leave transaxle in Drive and depress accelerator to floor (WOT). Transaxle should shift from 3rd to 2nd, or 3rd to 1st, depending on vehicle speed. Converter clutch should also release.
   NOTE: With transaxle in Overdrive, a 4-3 WOT downshift can be obtained regardless of vehicle speed.
4. With vehicle speed above 30 MPH, shift transaxle from Drive to Low and decelerate. Transaxle should immediately downshift to 2nd gear. When vehicle speed drops below 20 MPH, transaxle should downshift into 1st gear.
