Thanks for checking on that Slartyblarfast. I was going to suggest hooking an OBDII scanner up and seeing if it shows up anything.

I did some searching and found someone that also had a problem above 2500 and it turned out to be the transmission. Here's what was said...................

I knew it was going to happen someday.
Everyone seems to agree that Chrysler auto transmissions suck.
I punched it after leaving a toll booth this weekend. About 85% throttle.
Tranny slipped, got off it and then continued. Seemed okay. A few miles later a MIL.
Car goes into failsafe mode when trying to shift above 2nd gear.
There were/are no noises from the tranny.
Topped off the fluid, disconnected the battery, its fine for a few blocks (till I go over 2500rpm) then its back to failsafe mode.

Went to Lee Miles for a free diagnostic.
Scanner showed - P0733 Gear 3 Incorrect ratio
Lee Miles tech says its a mechanical issue in the unit.
He wants $400 to drop the tranny and find out, around $1500 when its done.
