If you have a JK with an Auto Trans, don't try to change the fluid and filter yourself. The exhaust pipe hides the rear four bolts on the trans pan to the point where it is darn near impossible to remove them. There must be a secret tool or some secret procedure to removing the rear four bolts. If you know the secret, please advise. I had a secret clearance in the Army, and I promise I won't tell anyone else.
