Grand wj 4.7 2002 overland 4'' lift. Have a snorkel kit ready to fit, going to exten the axle breathers. Anything else that I need to change/ extend/ waterproof for the wj to run well at wading depth?

 

YES the transmission breather is nothing but a hole behind the transfercase - it is fine for a quick crossing but if you stop you will be screwed.



You need to drop the transmission, tap the hole behind the torque converter and PLUG IT, and then drill a hole at the top of the trans and tap it and add a brass fitting so you can attach a hose to it.

I tried tapping the hole behind the torque converter and adding a fitting because I read a dodge forum post that it worked for someone, but the torque converter hit the fitting when I tried it. I know it sounds like a pain but burning out your transmission after taking water is WORSE !!!!

Here is a link with more info.

spray your motor electronics with wd40....it will help prevent corrosion in connectors, some guys even spray there entire motors with it

 

Put dielectric grease on all connections.
