To be honest with you I would not be suspecting the transmission just yet.
 
On 47REs the operation of the torque converter clutch is initiated by the Power Train Control Module (PCM) and very dependent on engine performance, load conditions, and driver input.
 
It would be very helpful to have a trouble code, which is accessible by the operator.
 
I would recommend checking the Throttle Position Lever that's mounted on the transmission for sticking or binding, or a broken or missing return spring. This problem can also be caused by an out-of-adjustment throttle cable. A bad Throttle Position Sensor can also cause this problem. Lastly, converter lock-up problems can be the result of poor engine performance.
 
Regards,
Dusty

Possibilities:
 
*Throttle Valve Lever on transmission stuck or binding, or cable kinked, damaged or binding.
 
*Throttle linkage sticking/binding.
 
*O/D switch circuit inoperative or switch defective.
 
*Engine not coming to full operating temperature, or defective Transmission Temperature Sensor.
 
*Transmission Valve Body - Low/Reverse Solenoid accumulator or switch valves sticking or leaking pressure, warped valve body or leaky separator plate; dirty valve body.
 
*Weak or defective TCC Solenoid.
 
*Worn Torque Converter Clutch.
 
*Bad PCM.

Dusty

I have 6000 miles on a brand new tranny, shifts fine through 1,2,3 and overdrive until I keep it at a consistent speed (from 45-65). Then the tranny constantly shifts between 3rd and 4th. I just bought a tps because the dealer and checker diagnosed that to be the problem but it did not help.

Assuming that the work on the transmission was competently performed, I would strongly suspect that the Throttle Valve cable and/or throttle linkage is out of adjustment. This adjustment is quite sensitive and should be done exactly per the service manual.

Alright well like I said I had the tranny went through last year and a new TC when it went back in. And I got the Chrsyler parts #'s of what I replaced a couple of days ago that didn't change anything. #4617210 solenoid, 52118500-AB solenoid, and 56028196-AD transducer. I dont know if that will help you any or not. And as far as the engine performance of the truck, there's nothing happening there. The engine is real strong and does great, I got a couple of performance upgrades on it- an Edge EZ chip and a K&N cold air intake but other than that its stock. And on the TPS it was replaced about a year and a half ago, so I would hope its still good. I dont know about the Throttle Position Lever or the spring on it. So man if ya got any other ideas let me know. I really appreciate the info so far.
                                                                Thanks Nick R.

99 dodge ram by ptonyt

Bought a 99 dodge ram quad cab with 80k on it last tuesday. First time I took it on the highway the shifting seemed a little funny but being my first truck didn't think to much of it. about 100 miles later... I was no longer able to go 75 on the highway... when the truck shifted into 4th or 5th it maintained speed at 65 ish at 1800rpm... when I tried to accellerate it would drop gears and sit around 3000 rpm and not accelerate with the pedal to the floor. Then when I got off the highway I could drive fine in 1 and 2 but as soon as I give it more gas and it drops a gear I got it to 4000 rpm.. but no power what so ever.... just kinda stayed the same speed.... Just bought the truck... guy said he never had a problem with it... and its never towed anything other than a single 4 wheeler.... any thoughts what this could be?
 
Thanks!
Tony

Did you ever find out the cause of this. My truck wont go into Park or Reverse so I'd love to know what was wrong with yours.
