Thank-you for the updates as they are most helpful!!!
I found the IOD fuse and it is good, so I will start will changing the TPS then get a trans fluid changed / flushed and get a new trans filter.
One question on the TPS, do you need to reset the PCM and if so, can this be done by disconnecting the battery for a short time or is there more involved. Thanks!

My 2002 dakota sport has 105000 miles on it I have the 545RFE trans. Problem is that when excelerating once I'm at 45 mph the transmission will jerk and seems to kick out of overdrive. If I were to stop shut the truck off and restart it I will have overdrive back. It doesn't happen all the time. If I keep it out of overdrive it runs just fine. The check engine light does come on but clears itself if it doesn't happen for a while. Just change fluid/filters. Still happening.

No, you do not need to reset the PCM after replacing the TPS. However, if after replacing the TPS things are still not right, try disconnecting the battery for two minutes and try it again. Sometimes the Transmission Control Module (TCM) will keep compensating for a TPS problem (Throttle Position Out of Range) and run the computer adaptive algorithm all the way to the end of its value. This can give you irratic or strange shift sequences.
You will lose all Priority 0 through 4 DTC stored faults and learned shift schedule. However, all Chrysler automatic transmissions are at least semi-adaptive (all RFE versions are fully adaptive) and after some drive time will relearn.

I could give you some ideas, but they could all be wrong. Since the CHECK ENGINE lamp has been illuminating, it is going to set a fault code in the PCM. This discussion will benefit greatly by knowing what the faults are.
In the meantime, have you performed any transmission maintenance on this vehicle in the past?

Late model A-series and all RE & RH series transmission have their identification markings stamped onto the edge of the transmission pan flange on the left side of the transmission case. There are three sets of numbers: the first ten digits are the part number, the second four digits are the build date, and the last set of four are serial number of the case. A-series had the model welded on the side of the case. Newer versions rely on the stamped part number. (RFEs use a white label.)
With the exception of the Aisin-Warner Jeep tranny, never use Dexron in a Mopar truck transmission. Never. Yes, Chrysler stamped the use of Dexron on to dipsticks for a number of years, and I can tell you they are real sorry now. They did this to indicate that Dexron could be used in very small quanity to bring the transmission fluid level to specification, however this was not approved in their service manuals. But, many people thought this implied that Dexron was approved for use, and it wasn't, especially in quanties more than one quart. As we know now, one quart of Dexron added to ATF+3 will cause accelerated degradation of the fluid.
If thje Throttle Valve pivot on the transmission is still sluggish, you may need to replace the shaft. I've seen these get corroded on older transmissions, especially those that had a high moisture content in the fluid (another reason to change fluid regulary!).
It sounds like you were reading TPS voltage with a digital meter. The voltages are within range, but you cannot determine a rough spot on the potentiometer wiper (resistive) surface with a digital meter. Here's where an old fashioned analog VOM will do a better job. However, I gave up on checking this after I found that I thought one was good after test, but it proved to be bad anyway. Because of the age and vintage, I would suggest just replacing it. They had a higher rate of defects in those years.
I'm not into tranny swaps, so I do not consider myself qualified to comment on the flex plate issue. However, I'm pretty sure the flex plates are different between a 42 and 46RH.
I think I answered all of your questions.
Good luck and best regards,

I got the truck with 70000 miles on it and I changed the fluid/filters at 105000. I just went and checked the code its reading P0700. Any ideas would be greatly appreciated.

P0700 = Transmission Control System Malfunction
Unfortunately the P0700 code doesn't tell us much, but I have a suggestion on a couple of things to try before going to a dealer and having a DRB3 connected to it.
1. Check all of the electrical connections at the transmission. Disconnect each connector and check for any signs of corrosion, moisture, or damaged pins. Check for damaged wiring. Perform the same checks at the Power Train Control Module (PCM) and Transmission Control Module (TCM). The TCM is part of the PCM and is mounted to the inside of the right fender.
2. Replace the Throttle Position Sensor (TPS).
3. Disconnect the battery for several minutes. This will erase the stored learned shift algorithm. Drive the vehicle and let the transmission relearn.
If these recommendations don't work, I suggest having a Dodge tech. check this out. You might need a TCM reflash. A defective shift solenoid or dirty valve body could cause this problem, as well as a bad coolant temperature or transmission temperature sensor, or for that matter, a bad PCM/TCM.

hey everyone newby here just wondering if anyone can help

Just curious if you ever got any response to your question...I am having the exact same problem with my 98 Dakota V6 3.9 ltr engine...EXACT same problem...fime after it warms up a bit....Transmission place wants $1350.00 to rebuild ( seals, torque converter? ann whatever else...

After checking all the wiring and replacing the TPS Im still having the problem. So today I took it into a respectable dealership to have it looked at. They checked it out with a DBR and informed me that I needed a rebulid ($4300). I have a hard time beleiving this and thought maybe you could either assure me that I need a rebuild or give me more ideas to the problem.
I have some results from the DBR test I thought this could be helpful info. Not completely sure what all of it means. But this is why they said I need a rebuild.
CVI: LR=93 2C=56 OD=55 UD=48 4C=0 (THIS 4C IS WHY THEY SAID I NEED A REBUILD THEY THOUGHT THAT SOMETHING WAS BROKE OFF IN THE TRAN.)
Also, since the last time I posted a message I've learned that the transmission is fine after it warms up.
