Started back up and drove fine after. Little scary to lose power on the highway with the kids in the car and traffic all over the place at rush hour. Went straight to the dealer where they put me in a rental and read the check engine light. Came back as incorrect gear ratio. So now they have contacted Dodge engineering and they recommend they replace the valve body due to possible debris causing this error. They were unable to duplicate this problem but as a precautionary measure they going to replace it and all new fluids/ filter. I barely have 6000 miles on the car and it is not modified besides a lmi hammer intake. At the time I was not even driving hard but was in auto stick mode.
Has anyone else seen this problem happen with our cars or older ones? I thought it was limp mode but the dealer has said other wise. As well I have numerous electrical problems with this car since I've bought it. Nothing major that they haven't been able to fix until now that it becomes a safety issue!!
my 2011 did something similar last year. What it turned out to be was a broken support bracket for the valve body. what happens is sometimes when the torque converter clutch breaks/beds in, it creates some debris, which can cause valves in the valve body to stick....they stick until enough pressure builds to release them, and that violent release can break this support bracket. it's not a common problem, but it is a known one. the tranny guy at the dealer knew exactly what it was when I brought it in before they even did the diagnostics/visual inspection, and the bracket needed was on national backorder, but they were able to get one through a transmission rebuilder that apparently buys all of chrysler's stock of this part when they become available.
the service manager said mine is the 4th car they've seen at the dealership with this problem since the LX's were introduced in 2005. the other 3 were all charger cop cars.
Chrysler's warranty procedure is to replace the bracket, and flush and inspect the transmission (and repair any other damaged items, like if the internal tranny speed sensor was damaged, etc). if it happens again, you get a new torque converter. of the 3 other cars that the dealer saw with this problem, only 1 came back a second time with the issue and needed a new converter.
they had my car for 2 or 3 days, IIRC.
