I took the stock air filter that sit on top of the computer out and replaced it with a free breathing high performance type filter. Since that day, it runs in "limp mode". The transmission stay in second gear and won't change. Can just changing the air filter cause it to run in limp mode or was that just a coincidence? We changed the transmission oil filter and put ATF +4 back in and that didn't fix it. Thanks for your help.

Sounds like a coinkidink.
Most common cause of limp mode is a bad speed sensor.

We changed both sensors on the drivers side of the transmission. That didn't help. What else can cause limp mode?
A TRANSMISSION SCAN TO READ THE INTERNAL CODES IS THE NEXT LOGICAL STEP.
Actually, I'd say that was the logical step before replacing both the speed sensors.
I agree, but you can't undo what was already done...so this is the next logical step before replacing any additional parts.
I had the computer scanned at a Dodge dealer and they charged me $81 to tell me third gear had gone out. I told him that when I drove in. He said it would cost around $2500 to rebuild it. I guess now it's the junk yard for a transmission.
