Lack of power from the engine intermitantly while increasing speed from mergin into traffic..speed around 35 -40 mph , trans is shifting but engine stumbles with difficult recovery, then picks back up..problem accurs once to twice in a 100 mile or so run..!

Thats gonna be tough since you would need to know exactly what gear the trans is in to figure speed based off rpm I would suggest just repairing the speedo or vehicle speed sensor which ever has failed

Did you check the universal joints. Then try a transmission shop if you think it's the trany. Should not be shifting into 3rd at 20 mph for one thing

Sounds like 2nd gear in the transmission is slipping. Cars usually shift at 15-20 mph from first to 2nd. First check the trans fluid.

Check your Tran oil pump or torque converter

real cold tranny fluid maybe,,., r u letting it completely warm up first?

Hi, the late shift, and late overdrive issue may not be trans. related, if you need to feather the accelerator to achieve your shifts, and you have a late sift, or loss of power, you may have a restricted fuel filter. The lack of fuel volume can result in what feels like a trans. issue, but in actuality, you are starving the engine for fuel. I would check this first, as it is an easy, cheap possibility. Good luck...Coop

It will shift out of overdrive upon increasing throttle , pulling hills and so on. Your overdrive probably kicks in around 35 to 45mph and kicks back out as you increase throttle. Electrically controled speed sensor to control the response. Overwise the engine would bog down to a stall. Over drive is just that. It changes the gearing ratio to over drive meaning less then final gear 4 to 1 down to 4 to 3 etc more direct drive ratio to lessen consumtion of fuel with less stress on engine. Have shift speed sensor adjusted. Don't drive in overdrive in city if most driving is under 45mph

It has nothing to do with the transmission, it's your engine mount thats bad.

Yes, the speed sensor is really easy to get to after you jack the car up. The trans. computer is detecting something is wrong and puts the car into "limp in" mode. I've seen alot of these speed sensors go out on the Chrysler products.

Your speed sensor in your trans. needs to be checked out sounds like its not working or not getting a good signal until its generating enough power and speed to start until it reaches 30 MPH. Check that out sometimes it could just be some dirt on it. It all makes sense the ABS light is on because its not reading the speed of the tires, and the AOD light is on because It has no idea when to shift into overdrive without knowing how fast its going. I sure Hope that Helps You Out, And Thanks, Bear001
