check the level of your trans fluid... if it isn't low maybe try changing the filter could be defective...

try changing your throttle position sensor. it's about $25.00 from the local parts stores and may cure your problem for short money. The TPS doesn't toss codes but will make your 4.7 and tranny do odd things when it's all munged up inside. It only takes about 2 minutes to change it if You have the proper torx bit driver handy. Before I replaced mine on my 2000 Dak with 4.7, there were no codes, but the engine wanted to idle at lower than normal rpms and the transmission was acting strange. also, before You start Your Dak, pump the fuel pedal from closed to fully open a dozen times before actually starting the truck. You might just have bad contacts (munged up) and it's causing Your problem when it's cold (as mine did) and when it gets warm it makes a better connection inside because the components have warmed up and expanded and making a much better contact.

I was thinking the same thing.
 
There is no single component on a Dodge truck that can cause so many varied and strange symptoms as the Throttle Position Sensor.
 
However, I would first suspect the transmission cable sticking, especially since the symptom is related to temperature.

no cable from the tps that I know of. the function of the cable is in the TPS itself. all transmission shifing is done by throttle position, engine load, and road speed.

Did you try changing the TPS. My 00 Dakota with the 4.7 was downshifting very hard when I slowed at stop sighs. The engine would idle near 1K and the gas miliage wasnt very good. I didnt have a scanner so I continued to drive the truck even on long tripps until one day I was driving to college and the torque converter kept coming unlocked and the trany eventually started down shifting on the freeway. I towed the truck to the shop I work at in the summer and checked the codes. The engine code said incorrect voltage for the TPS. The trany code said, tps voltage and map sensor voltage dont match. I drove the truck around for two days before I fixed anything. The problem didnt come back until I headed back on the freeway to school. I got almost the exact place on the freeway when the trans started down shifting again. I pulled to the side of the road and changed the TPS and had no problems the last 80 miles or the past 3months.

In the Dakota of recent years there are four automatic transmissions used: the 42RE (six cylinder), 45RE (318 V-8), 46RE (360 V-8, R/T only), and the 545RFE (4.7 Magnum V-8).
 
Each of these transmissions have what Chrysler calls a Throttle Valve Cable. This cable is used to controls shift speeds, shift quality, and part-throttle downshift speed (sensitivity).
 
Look closely at the Throttle Body Lever where the accelerator cable is connected. You will notice a second cable attached to this lever that routes downward along the right side (passenger side) of the transmission.
 
There is an adjustment procedure for this cable that must be followed precisely. If out of adjustment, slipping or shift flare, rough shifts, premature or late shifts will occur.
 
If the Throttle Valve Cable linkage sticks, usually at the transmission end, it will cause your symptom. There is also a return spring on the cable bracket at the transmission. I've seen these broken or completely missing. In cold weather I've also seen the pivot shafts sticking causing long shifts. These get gummy after some years from oil and road grime.
 
By the way, this very common problem accounts for many Mopar transmissions being "rebuilt" by shops that are less than honest.
 
Good luck and best regards,
Dusty

99 Dodge Dakota R/T Sport Transmission Problems by jmbrewer1

A few months ago, I purchased a 1999 Dodge Dakota R/T Sport with a 5.9L V-8(360)engine. Up to this point, I've had no problems. Yesterday, I noticed the engine revved to between 2500-3000 rpm when changing from 1st to 2nd gear. I thought to myself that I might need to have the transmission fluid flushed and filter changed. Later that day when I backed into my driveway, I could not get into Park. The indicator that shows what gear I'm in (P-R-N-D-2-1) is now off by a mark, ie. Neutral now shows as reverse, etc. The truck is still driveable right now but will not shift into Park. Any help would be appreciated.

Hi, I just rolled 140,000 miles today and my transmission started to make a low clicking when stopped at a light, only in drive or reverse not neutral, and today as I was pulling out of a parking space it hesitated it felt like I had let the clutch out to fast this seemed weired cause I have an automatic. It stopped as soon as I shifted to neutral then stalled out as soon as I put it in drive. I checked the fluid and it way above max then checked it again after it cooled off and it is at max when cold. The color was dark and smelled like motor oil. I have been losing oil, about a quart a month, but I have NO leaks any where and the exhaust dose not smell like burned oil. Could my oil be leaking into the transmission? And if so what would cause this?

The 45rfe, 454rfe, and 545rfe are all electronically controlled via a solenoid pack inside of the transmission. the throttle controlled valve body went the way of throttle body injection and carburetors. The TPS serves to control fuel rate and shift points of the tranny dependant on TPS position and engine load and rpms.
 
I've read several articles regarding the valve body control cable system, and for the life of me I couldn't find one on my 2000 Dakota Sport or my new Ram 1500. The health of any flavor of these transmissions is dependant on many factors. number one being maintenance. Anybody with a Dodge that uses this family of transmissions should follow the maintenance schedule in the owners manual and have them periodically checked by a good transmission repair shop or the dealership. If all of the procedures for maintaining these transmissions are followed, aside from periodic TPS replacement, they should provide decent service for the life of the truck.
 
 The reason why I toss TPS into the equation is because it will in fact cause the transmission in late model Dodge's to act erratically and possibly cause damage to the transmissions. The 2000 Dakota I just traded in required two replacement tps's in the two years that I owned it. in both instances the TPS and battery cable removal cured my truck of erratically shifting, hard shifting, and disconnecting the TCC at hiway speeds.
 
 Another item on maintenance is; for the life of Your Dodge truck, DO NOT USE DEXRON type fluids. Use CHRYSLER SPECIFIC fluid that is formulated for these transmissions. I have encountered many people who avoid Dodge's for transmission problems, and 99% of their problems were self-infliced by using DEXRON.
