Replying to: mtndewdude (Mar 09, 2009 12:34 pm) The following items can cause or contribute to this problem: *Engine not coming to operating temperature (bad thermostat) *Throttle Valve cable misadjusted, sticking, or binding (A common problem on older, high mileage transmissions) *Defective Throttle Position Sensor (common source for a whole bunch of problems) *Defective Reear Wheel Speed Sensor *Weak, defective, or intermittent Overdrive Solenoid *Dirty or worn valve body. Sticking O/D Check Valve, clogged Overdrive Clutch Bleed Orifice. *Low hydraulic pressure (leaky seals, defective Governor Pressure Sensor or Governor Pressure Solenoid) *Worn Overdrive Clutches Did your rebuilder gave you an itemized list of parts they replaced? Did he replace any clutches? Unfortunately, at 130K miles I probably would've replaced the valve body assembly unless everything looked very, very good. These are often found to have worn or scratched valve bores once they get over 100,000 miles. Regards, Dusty

Replying to: dustyk (Mar 11, 2009 4:34 pm) I believe that the engine temp is normal, the thermostat was replaced about the time the tranny was rebuilt. It warms up to about 190 and doesn't move from there, regardless of load. Not sure about the throttle valve cable, TPS or solenoid, will try those next if needed. I replaced the speed sensor (it was the one on the under side of the tranny, two wires, about $18) and disconnected the battery for about 5 min. I test drove it and took it up to 75mph, and everything seemed to be in good working order. The shift happened when it was supposed to, but had almost an intermitent stage. As soon as it shifted out of 3rd, it dropped slightly in RPM, but didn't seem like it was totally in OD (torque converter?). After I let off of the gas, it dropped in RPM again and was definately in 4th. I don't remember it doing this before this whole problem, but maybe it was supposed to? By the way, I called the transmission tech. He pulled up my bill and said he remembered working on my truck (gave an accurate description, so I believed him). He said he did a standard rebuild, replaced the clutches, and disassembled the valve body. He didn't see any scratches/grooves in the walls and said he cleaned it all very well. So the dirty valve body, sticking valve, and low pressure are unknown at this point. Dusty, thank you very much for all of your help. I try my best to fix something myself and it can be VERY difficult to find someone to answer [what seem to be] simple questions. Your help is much appreciated. Derrick

Replying to: rresa (Feb 20, 2009 6:56 am) Just following up with the issues that I experienced with my transmission. After replacing the TPS and getting the trans fluid flushed, the erratic shifting issues are no longer an issue and the fuel economy has improved dramatically. Thanks for the tip on replacing the TPS as it took car of not only the tranmission shifting issues, but corrected the erratic idle issues as well. It was $29.99 at Autozone with a 2 year warranty and takes on minutes to replace. Regards, Rich R.

I posted this about 1 1/2 years ago and no one had an answer, hopefully someone may be able to provide some insight now  I have a 2002 Dakota Quad 4x4 8cyl 5.9 w/ 86,000miles now 105,000 Recently when coming to a stop the transmission will either fail to shift from 2nd to 1st or will downshift to 1st but jump back up to 2nd after I come to a complete stop. After sitting for a minute it will sometimes shift to 1st ok, other times it doesn't and I have to manually shift it to 1st.(no problems with manual shifting) sometimes it now does not shift until i start to move again, even with trying to force it to 1st This is a rather intermittent problem, sometimes it will act up for the whole day, sometimes I can go for 5+ daysor months and not have any incident. I took it to a local shop, they ran tests, and pulled the pan. Tests came up clean. They claim the pan had some metal flakes in it. I unfortunately was not there to verify it. They want to rebuild it for about $2000. I am going to take to somewhere else for a 2nd opinion as I think having to rebuild a tranny at 86,000miles is absolutely nuts. However I wouldn't be totally surprised as there has not been much done in the way of maintenance. never did get the 2nd opinion Could this just be a case of neglect on my part and I just need to pony up for the rebuild or is there hope for a less expense answer? Thanks in advance for any suggestions. -Glenn

Replying to: glenn973 (Mar 18, 2009 8:37 pm) Before making assumptions or declaring a rebuild on this transmission, there are a number of things that should be checked before ripping it out of the vehicle. First, we need some vehicle history. What kind of transmission maintenance have you performed? Have you replaced any engine or transmission parts? What actions, if any, have you taken to troubleshoot the problem? You say this is going in to Limp mode. How do you know? Regards, Dusty

Replying to: dustyk (Mar 22, 2009 10:48 am) Thank you for your reply. Maintenance: Honestly, very little maintenance has been performed to the transmission itself aside from monitoring fluid levels. It has been serviced once(when I took it to the transmission shop to investigate the problem). I have not replaced any transmission parts, there was as issue with acceleration/jerking that sounds alot like the TPS issue I've read so much about, the dealership fixed that quickly. As for the engine, within the first year there was some issue that caused the dealership to replace the heads and I recently replaced the water pump & belts. Other than that it's been pretty trouble free. Troubleshooting: I have taken it to both a local transmission shop and the dealership, niether one was able to pinpoint the issue(nor were they able to get it to act up while it was in there possesion) Basically, they both said to drive it until it gets worse or just get the rebuild... I say limp mode because that is what the dealership said I was describing(if i remember correctly) The transmission shop said that it most likely was metal flakes floating around getting attracted to a magnatized silinoid(or something like that), causing the gears to get stuck. They said they could just replace the electronics, but weren't confident that would solve the issue... Let me know if there is anything else I can answer, i really do appriciate you taking the time to help me troubleshoot this issue. -Glenn
