Can you tell me where the grounding points are on the engine (3.3 L) and trans (auto) are? I heard that by ensuring proper grounding, the auto trans problem might be solved. Im experiencing a problem only when going forward into 4th where the transmission hesitates then goes into 2nd gear. If I do not put the selector in "D" but put it in "3" then it shift up to the 3rd gear without problems. This means that my max speed would be about 60mph with the engine rpm at just more than 3000. So, will proper grounding of the engine/trans solve this problem of not being able to shift to 4th? Thanks

Have you had a diagnostic scan done to determine if there are any codes stored in the computer? Sometimes the trans will store a code without turning on the light.
