I took the JK into the woods today. The following has been covered before, but I post this for review with numbers included.

Outside temp 88F.
Dirt roads in various conditions: moderate hills; several washouts; and other items making the max speed 10 mph.

4hi, transmission in "D", OD off, trans temp started to climb from the normal 130F range (stock cooler only). The transmission never got to 3rd, so the TC never locked up.
When it got to 180, and was still climbing, I switched to 4lo, OD still off.

Maintaining a prudent speed for the terrain, the trans shifted right up to 3rd, the TC locked, and the temp immediately started to fall. It settled in at the 165F area.

Since the engine and transmission were not hot enough to call for the radiator fan to come on, I forced the fan to come on by turning on the AC.

The transmission temp dropped another 10F and settled in around 155F.

Regarding the swaybar disconnect:
I was not into flexing nearly enough to "need" to disconnect, but disconnecting made the ride much more smooth.

 

how did you get these tempatures

 

AeroFroce gauge. And an in-pan sender and gauge.

 

Did you know you didn't need an extra sender with the Aeroforce for trans temps? The OBD II already has a sensor that rests in supposedly the hottest part of the transmission. That being said are you also running an external cooler plus how much extra weight (mods/recovery gear) are you running? That and elevation will make a huge difference in the temps you run.

 

Please read the 1st and 3rd posts more carefully. The answers to your first two questions are in there.

As far as added equipment, I added a front skid plate. Inside, two people and two gallons of water, snacks, etc., for the hike.

The original post was to illustrate to those who may not know, the benefits of 4lo and AC on, concerning automatic transmission temps. As I said, for review.
