Initial Inspection and Diagnostic Overview

Before suspected transaxle problems can be accurately diagnosed, it is essential that the following general checks be made in order to rule out problems unrelated to the transaxle that may falsely indicate transaxle trouble.
1. Check engine idle speed, ignition timing and overall engine performance.
2. Check selector lever cable adjustment.
3. Check for leaks on the transaxle (ATF) or final drive (hypoid oil), external damage or loose or missing mounting bolts.
Ensure transaxle is properly filled with the correct fluid. Inspect with vehicle level and idling. Check transaxle fluid with selector lever in N and with ATF lukewarm. ATF level must be between the two marks on the dipstick; the difference between the two marks is approximately one pint. If necessary, add only automatic transaxle fluids labeled Dexron or Dexron II. Use only a clean funnel and hose to add ATF and wipe dipstick only with a clean lint-free cloth. Do not overfill transaxle. Inspect level of final drive oil. It must be up to the edge of the oil filler hole. If level is too high or low, a transfer of oil between transaxle and final drive may be indicated. Ensure selector lever is in N or P and parking brake is applied during all tests in which the engine is running except pressure test and stall speed test.

ROAD TEST

Drive vehicle in all gear ranges and under all possible road conditions. Do not road test if there is obvious mechanical damage. Observe shift points and compare to table in Fig. 2. Shifts should be smooth and quick without a lag in power. Listen for engine speed up between shifts which could indicate slipping brake bands or clutches. Inspect for fluid leaks after road test. If transaxle performance is not acceptable, refer to ``Troubleshooting'' to determine possible causes for malfunction.
