Replying to: dustyk (Mar 18, 2009 12:57 am) i am not rplying to this post but i cant find another way of contacting you as you seem very knowlegable on auto transmissions. I am in England, i own a 1998 dodge ram 1500 5.9 pick up with petrol engine not diesel.It is a 4x4 auto. I am having several problems and i believe most may be linked. when driving at steady speed the tachometer will fluctuate 1-300 rpm. if i slow down or speed up it stops? also when driving the transmission appears to drop out of gear then go back up again if i speed up it sorts itself out untill i am at a steady speed again. If i accelerate normally it shfts fine thru all gears. This happens wether in or out of overdrive. Last of all when at fairly low speed ie about 30-45mph and when changing from i think 2nd to 3rd there is a weird noise, it is like a resonating/vibrating noise.again this dissapears if i speed up or slow down. a bit like a loose exhaust baffle but it isnt that, i have been under the vehicle and nothing loose at all. My fault codes ind TCC solonoid and intermittant cdk/cpk. I have ordered trans sump gasket and filter to do a complete trans flush. and i have also ordered a new TPS. any more advice would be apreciated. I am a skilled mechanic but i dont have much experience with auto trans. Many thanks Lee

Replying to: maxamus (Apr 26, 2009 1:26 am) First, how in the heck did a Dodge Ram 1500 get into England? I'm not aware of a right hand drive Ram being manufactured. Is it left hand drive? Based on your symptoms the Throttle Position Sensor most certainly would be high on the suspect list. Also, check for a binding engine throttlebody linkage, and a binding transmission Throttle Cable and linkage that's located on the left hand side of the transmission (driver's side). Regarding your other issue, I'm unsure what it might be. If the TPS is defective, it could be causing an abrubt shift that brings the clutches in too fast. (See my symptom list that follows.) Cheers, Dusty |

The following list of symptoms associated with defective Throttle Position Sensors (TPS) on Dodge trucks are a compilation of actual field experiences, both observed and reported: off-idle hesitation hesitation at speed rough engine idle intermittent rough engine idle rough idle then stalls engine RPM fluctuates at idle engine RPM flairs after start, then stalls engine stalls when placed into any gear engine stalls after start unless throttle pedal used engine stalls when throttle opened engine surges at speed engine performance poor: engine misfires under load/acelleration irratic shifts irratic torque converter unlocking irratic or over sensitive 6-5 downshifts at speed (68RFE) irratic or over sensitive 5-4 downshifts at speed (545RFE) irratic or over sensitive 4-3 downshifts at speed (RE, RLE) 3-4 driveline clunk delayed 1-2 shift delayed 3-4 upshift 3-4 upshifts occurs abruptly after 2-3 shift no 3-4 upshift no 4-3 downshift no kickdown at speed no or irratic torque converter lock up no or irratic overdrive shift Regards, Dusty

Replying to: dustyk (Apr 26, 2009 10:28 am) my truck got in to the UK in 2004 and yes it is a left hand drive. As soon as i get the new TPS i will fit and see if things improve. In the meentime i will check the cables as you suggest. Do you know of a test proceedure for the TCC solonoid or if it is suspect do we just have to fit a new 1? The noise i reported is very weird. i am sure it is something that is vibrating/resonating and i fear it may be coming from the transmission itself. When my other faults are rectified i might have a better idea. Amyway thank you very much for your advice and as soon as the new parts are fitted i will post a positive reply i hope. Cheers |

My ram is leaking in the transmission cooler line right where it meets up to the transmission cooler. There's no nut or anything on there to tighten, just wondered if anyone knew what could be done to fix this leak where the line actually connects in? It looks like it just pushes in there, and of course once I put the truck in gear, it leaks pretty bad from that connection. Thanks!! |

I have read alot on here about 3 to 4 and 4 to 3 issues but haven't been able to find one similar to mine. Hoping someone can help! My truck runs great and shifts smooth through all gears but...... When I start my truck after it has sat overnight, it will shift great (including overdrive) whether I drive if 5 miles or 100 miles. The button on the dash will operate perfectly during this time. It will go into and out of OD without any issues during this time. Once I shut the truck off, if I restart it (either right away or after say a half hour) it will no longer shift into overdrive and the light on the dash switch will not come on if I press it to disengage the OD. The next morning if I start it up it will work perfectly for the initial drive and then not work if I restart. I can repeat this isssue exactly every time I use the truck. I have good clean fluid and it is at the correct level. I have no other issues with the running of the truck. The truck has a new TPS as it was stalling at idle (the new TPS fixed the idle issue. This OD issue existed before and after the new TPS). The service engine light is not on and there are no codes shown doing the on/off/on/off/on check. Any thoughts on where to look would be appriciated Thanks, Art |

Greetings all, Does anyone have any advice on what could be the cause of the following intermittent problem. After driving my 2500 4x4 for 10 or 15 minutes, if I put the gear selector into reverse, the idle gets ruff and the engine stalls. Its not happening all the time on sometimes. Last night after this happening, once, I restarted it and went from 'drive' to 'reverse' again... it happened again. BUT... when I did the restart, I went from Drive to Park and THEN to Reverse... it didn't stall. All advice is appreciated! Thanks! |

| I have a 2001 dodge ram 1500 sport, i've been through 3 transmission!!! The first 2, i mudded the piss out of and i under stand them going out. But the last one was a heavy duty bought from "the transmission specialist" in Tom's River, NJ, it only has 6k on it. It never went into overdrive, but I got the sensor that needs to be replaced for that, but one day i jumped into my truck and 2nd gear was just gone. The rest are perfect, same with the last transmisson that went out. I can't remember if second was gone in it, but it wouldn't downshift properly. The weird thing is, is that i can stand on it and the rest of the gears are strong and there isn't any slipping. Is this a tranmission gone bad? or is it an electrical problem? Like i said this transmission, just one day second was gone, i had it the night before, and i started my truck up in the morning and went to drive it and 2nd was just gone. It didn't slip or anything before. Like i said it was supposed to be a heavyduty tranny, and it only has 6k on it. Please help me out, i'm on my last nerve. Is there any possibility that second is just fine and it's a electrical problem? If so what needs to be done. Also when i put this new tranny in, i flushed the lines and put in a new torch converter. any and all info would be very appreciated. | |
