Good Luck
I thought shifting to 2nd might resolve the problem, but it tends to jerk back on decelaration every 2-3 seconds, again at slow speeds.
I also noticed a vibration when pulling a trailer (5000lbs). At first I thought it was the brakes, but without touching the brake pedal, I feel the vibration right before it down-shifts to 2nd. This is in the tow/haul mode.
Seems like all three problems might be related.
Are these problems normal? Last time I took it to the dealer they said it's known software problem that they are waiting on a fix for.
Well I wanted to let those that may be interested of the problem resolution.
I am Sending this out as information just so anyone with the same problem has something to go on. I have a 2003 3/4 ton Cummins diesel not sure of the transmission type. I had noticed that I had too high rpm and it was not going into O/D and CC was not working. After a few visits to the dealership they found:
No codes that there is a problem Scan JTEC and seen that TPS was bobbling from 5 volts to 2.6 volts while driving. Ordered PCM and wiring harness. PCM had some corrosion and trans harness corrosion in JTEC connector. Replaced PCM and Trans wiring harness. Replaced neutral Safety switch due leaking oil out and into wiring connector. Road test trans shifting and CC working as designed.
I wrote all this as it was written on the Dealership report. This was all covered under an emissions warranty. There was a recall on some seals about 3 years ago that related the wiring and during that replacement corrosion may have been reintroduced. I have found a lot of good information on these sites in the past so hope this may help someone.
1# new governer pressure solenoid
2# new governer pressure sensor
3# Insist they replace the pressure regulator valve with line to lube sonnax valve
4# insist they replace manual valve with line to lube valve
#5# MOST IMPORTANTLY removal of the checkball and spring from the cooling line at the radiator failure to do this could result in a failure in just a matter of days leaving you on the roadside with your geartrain lying in the bottom of your trans's pan if your towing consider having an aux cooler installed also
Information on the above listed valves can be found at www.sonnax.com transmission id= 46RE
I have a 2001 1500 4X2 with 5.9(360) \ 46RE. It began shifting erratically the other day (sometimes it shifts fine, other times it refuses to shift out of 2nd gear). Before this happened I knew that I had to replace a failing neutral safety switch because there was trans fluid leaking from it. I took it to the shop, there were no engine codes but the mechanic told me that during a road test when the trans failed the Gov Pressure was reading 5psi and he said that it should have been between 45-50psi. They suspected the governor solenoid and governor pressure sensor. They quoted me $600 but after reading these posts I figured I can do it myself for a third of that price. I dropped the pan and looked inside - only problem is I have no idea if the deposits that I am seeing are normal for 140k miles or if it is terrible and I should not waste any more money trying to repair it (the gasket was in pieces so I do not think the fluid has been changed in a while, if ever). If anyone out there could take a look at these photos of the pan and share you expertise it would be greatly appreciated.

2006 5.7 Hemi with about 60,000 miles. Two problems:
1) Tranny shifts into OD when I take my foot off the gas and will stay there - down to around 20-25mph or until I push the gas.
2) When accelerating from OD, the tranny makes a shuddering/vibration sound. It sounded to me like the heat shield on the exhaust.
I've taken it to AAMCO - they found no errors on the diagnostic machine. They suggested the first problem may be that the tranny is going into lock-up which may be a result of an on-board computer problem. They said the computer needs to be flashed.
They also said the shuddering/vibration is clutch chatter but offered no fix for this problem.
Any ideas from other Dodge owners? I'm out of warranty for replacement.....
My pickup stopped shifting and remained stucked in the first gear. in the beginning it would occasionaly jump to the next gear and then shift normally up to the other's. I had it scanned and was recommended to change the output shaft sensor which we did today, but the problem remained the same it is not shifting at all no more
Does anyone have an answer, suggestion on this issue?
P0720 Output shaft speed sensor circuit. and also
OD Park, Neutral, Drive, Low Switch Circuit High 61 passenger Door lock / Unlock switch Input Circuit high. DTC Ignition Run/ Start Circuit Rationality
Kindly what are your recommendations based on the above codes?
The problem was the Universal joints.
In the past 3 weeks my truck has been shifting gears really hard.
Only going up hills...
When it wants to shift down when going a a hill it clunks really hard.
Only going up hills.
Flat land no problems.
Changed trans fluid about 25,000 miles ago.
Any ideas out there???
Thanks....
thanks lots
