Replying to: dustyk (Feb 22, 2009 9:39 am) 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. Thanks, Nate

Replying to: ndc (Feb 22, 2009 10:51 am) 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. Best regards, Dusty

Replying to: dustyk (Feb 22, 2009 7:16 pm) 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. Thank You, Nate |

Replying to: 02flhtc (Feb 24, 2009 5:51 pm) I would first replace the transmission filters, both the Primary Transmission Filter and the Cooler Return filter. The Cooler Return Filter looks like a very small spin-on engine oil filter. Chrysler became extremely sensitive to debris management with the RFE transmission series. It incorporates an exceptionally fine filter media that traps debris down to 6 micron. Unfortunately, this is a high efficiency filter with a relatively low capacity and it can clog easily if there is a lot of debris in the fluid. Also, if its ever been replaced, there were some Cooler Return Filters that were bad for a while. If this does not solve the problem, try disconnecting the battery for two minutes and go through a relearn. If that doesn't work, have a Dodge technician put a DRB3 diagnostic tool on it. You may have lost the shift algorithm or need a flash update. Regards, Dusty

I have spoken with a few mechanics and they all agree the Dodge 45RFE is a solid transmission. But if you goto some of the shops they will say you need a tranny straight up. From what I have read, the TPS can be a issue, also computers become corrupted and need to be reflashed, about $100. The other issue is the transmission input and output sensors and there are 2 filters that need to be replaced when doing the trans service. There's a flat one and a spin on inside. I have done changed everything but the two input/output sensors. Each time the trany has improved but still issues, hoping the last 2 sensors do it. Will replace this week

Replying to: rx2man (Mar 01, 2009 7:14 pm) There was a loose accumulator plate problem on some early versions, which would cause the plate to eventually bend, I've heard of a couple of marginal sensors, and yes, the Cooler Return Filter can get clogged very quickly on these trannies. But all these problems can be resolved on the vehicle. Regards, Dusty |

Replying to: ndc (Feb 27, 2009 3:06 pm) Based on your numbers there is something definitely wrong. The Low Reverse clutch pressure is too high, the 2C clutch and Overdrive clutch pressures seem within range. I consulted with a Dodge tranny tech and he thinks the Underdrive clutch pressure is too low. The 4C clutch pressure doesn't make any sense since you say that after being warmed up it drives okay. Basically at zero it's telling you that the 4C clutch requires absolutely no pressure to apply which doesn't make sense if it drives. This could be an erroneous reading I suppose. The rebuilding quote seems unreasonably high. Heck, you could probably buy a brand new complete transmission across the parts counter for nearly that price. Unless this transmission's been abused, I would suspect that most of the hard components are still good (panetaries, shafts, etc.). You might need clutches or maybe a valve body, but that would be just speculation. You really don't know until you pull it apart. You know, it might pay to get a second opinion. Regards, Dusty
