In my OB I notice each time I put the car into Reverse I get a MEAN clunking sound (4 Speed AT). Whenever I have to drive my car somewhere the parking brake is engaged, I set the gear selector to wherever I need to go (foreword or backward) then disengage the parking brake. Does this method put an excessive amount of stress on the transmission or the mounts?? The clunking sound is louder when the car is fairly cold but if I'm driving around and go to the store park it, then eventually have to leave the clunk is less noticeable. There was another method for "muffle" the clunk as well: Put the gear selector in P, 3, then R and see if the clunking is still there. Checking underneath the car I notice the trans mount has rubber material on the inside (maybe OEM mount?) Should I replace it with something else or am I overreacting?
