how would i tell if my jeep has one of these? my liberty did not come with the tow package
and i called my dealer to ask them how much it would be to add a trans cooler and hitch they said i already had a trans cooler but i thought it only came with the tow package.

What year do you have? Libbys that have the 42rle tranny have the cooler already.

thanks i went and got my window sticker and it does say that it has the 42rle.
now what about towing with a lift in the owners manual it say's not to do it but have any of you done it with no probs im looking at getting a 2 1/2" lift with 28 1/2" tires..
would i still be able to tow my quads?

Umm, well, you can tow just fine with a lift. The 28.5in tires would look kinda stupid though. Mine came with 29in tires stock and with my 1.5in lift, they looked decent. it looks really good with the 30" tires. I wouldnt tow with my 30"tires, but it does just fine with my stock tires. I dont believe quads weigh that much anyway. I would say around 700-800 a piece?

sorry i must be confused maybe it has 28 inch tires and after the lift i can go to 30 1/2"
im still a noob trying to figure all this out

All auto trannies have a cooler, if you live where it's hot or tow a lot, you can add an auxillary cooler to the front of the radiator to help with the extra heat. Get one sized for your frontal area and max load rating. It plumbs inline with your existing cooler lines so the plumbing is easy. Your rig will tow fine, but a little slower in the hills, brakes will wear a little faster due to the larger tires. People tow travel trailers behind their lifted KJ to Moab, etc. so you should be fine. If your pulling more than 2500 lbs, total weight, than I'd get brakes on the trailer and a brake controller on the rig to help you haul all the weight down due to your short wheelbase, and wear and tear on your rig's braking system.
