2001 Dodge Ram 3500 Diesel Transmission problems/shutters on 2001 Dodge Ram 3500

2001 Dodge Ram 3500 24 Valve Cummins Turbo Diesel 4x4. It feels like the transmission slips when driving around 45-55 mph, with or without OD. Tranny filter and fluid changed. Truck also has a Dyno Power chip. What could cause this? Could it be a throttle position sensor or idle position sensor? Or could the clutches just be burned up?

I found this on Repairpals common problems page for your Ram Drive Train: POWER TRAIN:AUTOMATIC TRANSMISSION Service Bulletin Number: 1800602A NHTSA Number: 630803 Model Years Affected: 2000, 2001 Date of Bulletin: 04/2002 Bulletin Summary: SUBJECT PERTAINING TO SURGE, LACK OF POWER IN 3RD GEAR, AND NO 3/4 UPSHIFT AFTER 4/3 DOWNSHIFT. My 1998 Ram Diesel Had a shifting problem and Dodge had to reflash the computer and said it was a recall item and its been shifting fine ever since

IN MY 2001 3500 RAM AUTO TRANS. DID THE SAME THING BUT MY TRANS CAME LOOSE AND LOCKED INTO LOW RANGE WHILE GOING 60 MILES AN HOUR AND WOULD NOT GO BACK INTO OVERDRIVE. BLEW TRANS FLUID ALL OVER THE UNDERCARRIAGE AND STOPPED. BATTERIES AND CONNECTIONS HAD NOTHING TO DO WITH THIS PROBLEM. RE-BUILD WITH SHIFT KIT HEAVY DUTY TORQUE CONVERTOR,AND PUMPS. REPAIRED,REPLACED @ $3500.00. GOOD LUCK WITH YOURS.MINE SUCKED!. WHAT HAPPENED TO THE ALLISON TRANS?.
