Any discussion yet about the recently announced recall? It applies to all Auto Trans equiped JK's from 06-08. I would think it's a pretty serious issue for guys here. I'm particularly interested because I'm somewhat peripherally involved.
When I was working at Dana in 04-05 designing underhood plumbing, there was an issue on the Dodge Ram where it was the only large pickup made that did not have a transmission temperature sensor. Ford and Chev both had one. In the Dodge, if you're doing heavy, slow off-road, the transmission builds and builds heat and can't shed it well. That part is normal. What was abnormal was the lack of a transmission temp warning. The driver could work the truck with no indication of a problem. Transmission oil temps could climb well past the working limits of the fluid. They could keep climbing to levels that would eventually melt the rubber hose on the trans cooler lines, with obvious consequences.
Looks like the same issue applies to the Wrangler. I'm not sure why all the sudden they decided to recall the Wrangler now, when they've had this same flaw on other vehicles. I'm not sure what has changed since I got out in 05. it might just be that the Wrangler is the only vehicle used off-road enough where this problem attracted the attention of the NHTSA. The recall states that it's a problem with the transmission overflowing out the vent, and the fluid drips on the cat and catches fire. I don't think that's the extent of the problem.
Apparently they are going to install a temp sensor in the vehicle, and reprogram the PCM to give a warning on the driver display. I wonder how they plan to wire it?
I would recommend anybody with one of these vehicles get this done.
