Hello all. I have a 2013 automatic JKU and I am considering either a supercharger or V8 swap. My question is, should I replace my trans or is there any upgrades available as far as clutch packs or something. I have 125000 miles and I dont want to do all this and have it go out right away. I figure there has to be something out there to add a little extra holding power. I do drive it pretty hard and go to the dunes. I have 37" tires and 4.88 gears. Thanks

 

With the supercharger I think you should be good with the stock transmission.

If you go with a V8 Swap get the transmission with the motor that way you know they work well together and most important mate up with out an adapter.

 

What Canvas said.... likely you would get a better market for the 3.6 w/ the transmission than without.

 

I guess my main concern is either way the trans has 125000 miles on it. How much more power or even use can it handle. Im leaning more toward the super charger. they seem to be putting out really good power. I just dont want it to be burned out 5000 miles later.
