When A/C is off.. transmission runs smoother? Why?
Earlier this year I had my 722.3 transmission on my 92 400se replaced with a rebuilt AT. Since then, after the car reaches operating temperature, I experience "hard" shifts.
The independent mechanic doesn't seem to have the knowledge to diagnose or address the hard shift problem. It is interesting when the air conditioner is not operating, the shifts are much smoother. I have checked the vacuum line and connectors from the engine to the modulator valve with a vacuum tester. The line will hold presser. Any suggestion would be appreciated. Thanks, Russell
