I have an 06 3500 with an automatic trans, I just changed the trans fluid and put a fresh filter in it. I have 32K miles and the truck has never towed anything heavy. When I am driving and not hard on the gas, it feels like the trans bounces between first and second gear a couple of times before shifting into second. If I am hard on the gas it doesn't do. Any help would be appriciated, and any other trans info would be nice as i have heard of the nightmares about dodge transmissions.

Yes you can just take it to a dealer and you need to just tell them you want that particular TSB done because your tranny is hunting for 2nd in low rpms.

I don't know if your truck has adjustable bands or not. When I service the trans in my brother-in-laws '03 I always adjust the bands too. He says he can feel the difference in shift quality and firmness instantly.

I had the same prob with my 03. I took it in after I smoked the stock tranny an had new VB, TQ, OP-shaft, an my truck still does it. It has to do with a TPS prob with all CR an newer. If you search there are more post that state the same thing. :peelout.

i think mine is starting to come back. I am going with an aftermarket valve body and torque converter to tighten up the trans

help needed

My truck will take couple of seconds to react and start moving when shifted on reverse, this is happening typically if the truck has not been driven for a few days, also the tranny feels erratic sometimes when going low rpm's. Has anyone have encountered the same problems?, Thanks.

Sounds like the converter is leaking down. Try holding your foot on the brake, shift it into drive, wait a second, then to nuetral and wait a second then into reverse and backk into drive. Each time you do this you should the trans shift into gear harder. If i leave mine sit over night or for maybe 2 nights it doesnt want to move. I do this every morning regardless if it feels like it needs it or not. A bad converter can reek havoc on the trans. Fill out your sig and it will help see if anything is done to your trans that will help pinpoint this a little more. I suggest a aftermarket torque converter and valve body. I am gonna do this as soon as i get a little extra cash

I am guessin its out of warranty so they will most likely charge for it. On the first page of this post there is a step-by-step procedure for this. It has the part number for the solenoid right on it. You do not need the gasket, you can reuse your old one. I would get a trans filter and replace that since you will be in there too and then the fluid.

the only part of the warranty that runs to 100,000 is the cummins engine. I think that only pertains to new 07's and 08's. Which i think its still called powertrain, but or course thats not the drivetrain. Its all a joke, and it is pretty easy to do, but anyways i hope this helps
