At what temperature does the HOT OIL indicator come on?

220 degrees I think

joe002

Thanks. I haven't seen anyone post the temp - 220 is hot but doesn't seem extreme?

Here ya go



33

Yeah, 220 doesn't look too extreme to me. I guess if you hit 220 then stop and idle to cool it down then you really shouldn't have to worry about damage.

Don't put to much faith in Chrysler sensors it could be 250 or 150 or 350

It's not 150, my transmission has hit 190 with no HOT OIL indicator. 350 would be a killer.

I use my Bully Dog to monitor the tranny temp and in Summer it normally hits 190 to 200 during traffic jams without activating any alarms. Of course, it is relying on the Jeep's temp sensor and the computer to display the measured temperature. But it has been quite consistent.

Nonetheless, the Summer temperatures in Seattle are very mild. I imagine this would be quite higher in the South.

I monitor what the Jeeps computer says is the transmission sump temperature with an AeroForce, and also have a probe in the pan with a gauge on the a-pillar. The gauge and the AeroForce gauge consistently agree when I check one against the other.

I have the gauges too. Mine has gotten up to 220 in a chicago summer traffic jam, no hot oil light. I have the cooler now and it only gets up to 170ish and that's all :-) prolongs the trans life!
