Stalls when engaging to reverse, when engine is cold. It is ok after driving 10 miles or so.. HELP
How many miles on the vehicle?
Regards,
Dusty
Thanks for your past help. It saved me a lot of money.
Thanks for your time.
Thanks,

This same guy next orderd a MANUAL xmission (same type of Dodge ram truck)and never again had transmission issues while doing the same work that the automatic xmission whimped out on.

1. In O/D the transmission acts like it wants to downshift all the time.
2. with O/D off the transmission shifts up to the next higher gear but does it slowly( high RPMS), if I shift it into nuetral and back to drive it shifts correctly.
3. It always downshifts properly when I come to a stop with O/D off.
4. Occasionally when I am stopped at a light it surges forward for a secon then stops
I have been looking for the cause because I had taken it in to get the fluid replaced and the dealership told me the fluid was fine. Since it drives differently in O/D than without it I think it is electronic. I have read the TPS fix and taking the negative lead off the battery which I am trying now.
Please let me know if anyone might know what is going on with my truck. I just bought it used a month ago and I love it but dont want to replace the transmission if I dont have to.
GENERAL INFORMATION
The transmission throttle valve is operated by the valve body throttle lever. The throttle lever is actuated by a cable connected to the engine throttle body lever. A lock button at the engine end of the cable provides for cable adjustment.
A correctly adjusted throttle valve cable, will cause the throttle lever on the transmission to move simultaneously with the throttle body lever from the idle position. Proper adjustment allows simultaneous movement without causing the transmission throttle lever to move ahead of, or lag behind the throttle body lever.
CHECK
Turn ignition key to OFF position.
Remove air cleaner.
Verify that throttle body lever is at curb idle position. Then verify that transmission throttle lever is also at idle (full forward) position.
Slide cable off attachment stud on throttle body lever.
Compare position of cable end to attachment stud on throttle body lever:
Cable end and attachment stud should be aligned (or centered on one another) to within 1 mm (0.039 inch) in either direction.
If cable end and attachment stud are misaligned (off center), cable will have to be adjusted as described in following procedure.
Reconnect cable end to attachment stud. Then with aid of a helper, observe movement of transmission throttle lever and lever on throttle body.
If both levers move simultaneously from idle to half-throttle and back to idle position, adjustment is correct.
If transmission throttle lever moves ahead of, or lags behind throttle body lever, cable adjustment will be necessary. Or, if throttle body lever prevents transmission lever from returning to closed position, cable adjustment will be necessary.
PROCEDURE
Turn ignition switch to OFF position and shift into Park.
Remove air cleaner.
Disconnect cable end from attachment stud on throttle body.
Verify that transmission throttle lever is in idle (full forward) position. Then be sure lever on throttle body is at curb idle position.
Insert a small screwdriver under edge of retaining clip and remove retaining clip.
Center cable end on attachment stud to within 1 mm (0.039 inch) and release cable button.
Install retaining clip onto cable: housing.
Check cable adjustment. Be sure transmission throttle lever and lever on throttle body move simultaneously and as described in cable adjustment checking procedure.
This does NOT mean that the clutch needs to be replaced.... but it does not make sense to replace throwout bearing and not clutch while it is torn apart.
It is also possible that a noisy throwout bearing can last a long time.... just spend as little time as possible with the clutch pushed. It is good driving-habit with manual trannie to NEVER sit still with clutch pushed... if you are not shifting, DONT have the clutch pushed.
In many years of driving manual xmissions I have never EVER worn out a clutch nor throwout bearing. (To save the clutch, do not touch throttle pedal until AFTER enguging the clutch... it takes practice - but it is possible.)
I appreciate any help.
The 42RE, 45RE, and 46RE transmissions use solenoids to shift gears in a normal upshift pattern, but utilize a Throttle Valve Cable to control part-throttle kick down and shift speeds. That is why Jknisley (post 167) has three cables at the throttlebody. One is the accerator cable, the second is the cruise control cable, and the third is the throttle valve contol cable.
Only the 545RFE ("FE" = "fully electronic") does away with the Throttle Valve Control and relies solely on various electronic sensors for complete shift control.
Bests,
Dusty

The battery is less than 6 months old. It's as if the transmission controller got into some anomolous state. I'm not sure if I was in a "limp" mode or not, since I don't know what the "limp" mode is like for a 45RFE.
Did you check for an open IOD fuse? If this fuse is open the transmission will operate normally for a while, then cause the transmission to go in to limp-in mode. The IOD fuse supplies memory keep-alive current for all vehicle control modules when the ignition switch is in the off position. Your symptoms are very common for an open IOD fuse.
The IOD fuse is cavity 12 of the junction block on the left side of the instrument panel in the 2003-2004 Dakotas.

Dusty
My first suspicion id a clogged transmission filter and/or low transmission fluid.
Regards,
Dusty
You may want to consider a full and complete xmission service including all filters. Also consider using the synthetic fluid of the 2001+ xmissions. (ATF+4)
Make CERTAIN that only the proper DODGE xmission fluid is used. Using any other fluid (like dexron) can really mess up a Dodge xmission due to the different clutch friction the wrong fluid imparts.
A cold start delay in to gear usually indicates low pressure.
Do you know which transmission you have? Either a 545RFE or the 46RE.

Dusty

In electronic language I'm pretty sure the O/D switch is a momentary contact, normally closed device. The switch must be closed in order for the solenoid to allow a 3-4 shift in normal operation.
The switch is removed by using a small tool (screwdriver) to pry the switch away out of the end the gear shift lever. There after the switch can be checked using a multimeter.

Dusty

I'm thinking you have a 42RE, or the 3.9L V-6 motor. Please let me know if this was an incorrect guess.
It could be in the "limp-in" mode since it's trying to start in second or third gear. If you got a MIL illumination, that usually confirms it.
Check all of the fuses in the vehicle. I'm not sure about a 2000, but on 2002s and up the IOD fuse is located in cavity 12 of the instrument panel junction block. An open IOD fuse will cause the transmission to go into limp-in mode.
If all of the fuses check good, disconnect the battery for approximately one minute, reconnect and drive the vehicle. If the transmission shifts okay you could've lost the shift algorithm If this does not fix it, then I suspect you've got a governor circuit problem, either electrical or hydraulic.
I would then check the connectors at the transmission, the Transmission Control Module, and the Powertrain Control Module. Also check for damaged wiring. You'll need a schematic, but I would check all of the circuits coming from the Shift Solenoid Pack in the transmission back to the PCM, TCM.
Also, check the ground strap to the transmission and make sure the transmission is properly grounded. These get corroded on older vehicles. Use a good digital meter. There should be zero ohms between the transmission housing and the engine and the bulkhead ground circuits.
Good luck,
Dusty

Yes I have 42re trans and a V6. I have check everything that you recomened Checked all connections, for cut or broken wires nothing that I can see. I'm sure the power relay is working because overdrive is working goes in and out overdrive. I do get p0748 when scanned. check fuses and grounds. I guess I will take in have the Dodge dealer look at it. any other things??
Thank You Mike
