i have a 02 trailblazer ltz the 1-2 servo i think the outer cap is rusted in i have the ring clip out and the cover cap will not spin or go in and out so what will happen if i start my car and put it in gear to blow the old 1-2 servo out of the trans will it do anything to the trans itself? ---

The factory manual states this tool must be used to remove the servo cover. [http://www.handsontools.com/Kent-Moore-J-29714-A-Servo-Cover-Depressor-J29714-A\_p\_24318.html](http://www.handsontools.com/Kent-Moore-J-29714-A-Servo-Cover-Depressor-J29714-A_p_24318.html) It also states that the servo cover can get hung up on the servo cover O-ring. If this occurs, cut and remove the servo cover O-ring. Tester ---

The trans case is aluminum. No rust to speak of. Surprising how o-ring will get pinched and hang up the cap.
