Do you have an auto or manual? If auto you will need to "waterproof" tranny. I would guess auto is in the same family as the 2000-2001 models. These auto's have vent hole behind the torque convertor. When water is deep enough that torque convertor touches water it throws it up and water works it's way into transmission. Friend had this happen twice to him in his 2001 TJ. I'm planning on doing a modification shortly to my 2000 TJ to correct this engineering screw up.
