Tranny cooler
Ok I read a bit but can't find my answer. I just bought a trany cooler for my 09 jku auto but am unsure if I need to keep on the old cooler or add this one to it. It is the best one autozone had for 65$. Can anyone help with this? I had the hot oil light once already and don't want it again.

The instructions should make it clear. All the coolers I've installed (none on my JK yet) have kept the stock cooler in service.
Even with the cooler it is good to keep the tranny from generating unnecessary heat. Do this by running in 4-low when possible. This keeps the tranny cooler because instead of running, say, 2200 in high range and first or second gear with the torque converter unlocked, the engine will run 2200 in low range and third or fourth (OD) with the converter locked up. A locked converter produces much less heat.

You keep the original cooler in the circuit. Cut the line that returns fluid to the transmission. This way, the fluid goes into the original cooler, then into the aux cooler, then back to the transmission.
It's the top line on the side of the transmission that is the return line.

You will be cutting the return hose, so two double-ended barbs will go there.
Most people say some extra hose is needed, too.
