One problem related to automatic transmission cooler has been reported for the 2007 Jeep Wrangler. The most recently reported issues are listed below.
Chryslers recall for the temperature warning addressed the symptom not the problem. The transmissions are still overheating in the Wrangler. The solution is a $50 transmission cooler. This can happen both when off roading(which the Wrangler is built for) but others in our Jeep group have had the situation happen on road. My situation happened while driving on approximately a 20% grade on a dirt road at 20 mph---hot oil light came on and was forced to stop driving to allow cooling---later found out from the jk-forum online Jeep group that this is very common and that dealerships are not correcting with transmission cooler. . . But it is something you can do yourself if you have some mechanic skills. The issues is. . . If you add the cooler Chrysler can void you warranty. Please look into this as I said their recall under your number 09v436000 addressed the symptom but did not solver the real issue---[xxx] information redacted pursuant to the freedom of information act (foia), 5 u.
