Driving home truck was running fine. check engine light and trans fluid lights come on. pull up to a stop sign and the truck jerks on take off and will not go over 40 pushing 2800 RPM. Get it home cools for two hours take it back out truck runs like it just came off the lot. codes P0700 and P0740 show up. New transmission or a sensor somewhere?
Yeah, generic "circuit malfunction" codes, it's a bad solenoid or two or valve body, either of which can be fixed by a HONEST transmission guy with high end diagnostic gear CHEAPER than a new tranny. OR...you can check solenoids yourself as you replace tranny fluid/filter, new fluid and filter did it for me once

same thing happened in my dodge, come to find out it was the transmission module in the computer, computer needs changing out. I got the true reading from auto zone, transmission shop couldnt get right reading for a year and a half, try auto zone first, they can pinpoint your problem and its free, good luck

replace the input speed sensor to transmission and the wiring pigtail all are available at your chrysler dealer take your vehicle registration in to the parts counter so they have your vin # to get the right part and it is the front of trans by fluid linres to radiator.

It may have a "loss of prime" code that usually follows a service of the fluid and filter. After you're sure the fluid is full at operating temperature, disconnect the battery for a few minutes and reconnect to see if the code resets. I hope this helps.

1st try and search for a vaccum leak, due to the fact that these vehicles have had some bad problems with the length of wires and hoses, if there is a vaccum leak in the vehicle somewhere that will trigger other malfunctions in your vehicle. Using a can of starting fluid or Brake cleaner spray lightly spray around our engine til you hear the motor rev-up and the spot you have sprayed will determine where your vaccum leak will be. And then check under your distributor cap for any moisture be sure to take a rag and wipe and residue off. Also check the firing order on your distributor.
