2004 Dodge Ram transmission will not shift?

2004 Dodge Ram transmission will not shift? I was riding at normal speed and something sounded like a pop, transmission down shifted to 3rd gear, just as if you had changed to tow mode. Rpms went up and trans would not shift, stayed in 3rd gear. What could this be and how can it be fixed?

"John, As a first step, have a good Technician scan for trouble codes, diagnose and estimate repair. Takes a lot of guess work out of transmission fault diagnosing if there are codes set.

I hope this helped you out, if so let me know by pressing the helpful button."

I had the same thing happen 3 weeks ago. Cruising speed. 'Pop' (a jerky, kick-down, really). Check Engine Light came on. Now in 3rd gear. Wouldn't downshift at stop sign. I turned off engine. Restarted. Transmission shifted right, but R-N-D shifts with a sloppy 'bang' (like a bad u-joint). I disconnected the battery. Waited 2 minutes. Reconnected Battery. Ck Eng light gone and truck back to normal. After 1200 miles of my regular driving, its fine. Good Luck.

Make sure fluid is at right level because most probably it is caused by improper fluid level or thickness of fluid. Also check your clutch linkage or shift cable and adjust them if necessary. One more problem that causes gear shift problem is vehicle’s computer system that controls the automatic transmission as you see at buyusedengine(.)com. You need to reset it. Resetting takes most likely 30 minutes but if even after resetting, it doesn’t work, time to go for a mechanic.
