2nd Generation Dodge 24 Valve Powertrain

I can get my NV5600 to shift if i am creative enough but it always wants to grind on upshifts. Notably worse between 1st and 2nd, 2nd and 3rd, 4th and 5th. 6th has never ground on me, and rarely a 3rd to 4th shift will. It never grinds on downshifts though. Also there is a rattling sound when idling second, usually when i am turning slow speed through a parking lot...but no rattling when accelerating while going straight. I am positive the sound is coming from the transmission. Any clues? :confused:

Wondering what I can do to help lower transmission temps drastically. The other day I ran a little over 200 degrees pulling a 7 thousand pound trailer. (Built tranny with triple-disk TC, shift kit, and heavy duty bands.) Do you guys recommend transmission coolers/fans? Drop some links in the comments of products that you have or have opinions on. Thanks a bunch! Also, have you guys read about the new Smarty MM3 tuning for 98.5-02's?!?

Just got my truck back two days ago from tranny rebuild. I went to pull out with trailer today and make around 25 miles to fuel station. Tranny temp @ 195*, gears are not catching when putting into D,3,2,1 or R. I shut the truck off and turn it back on and it would make it maybe twenty ft before doing it again. I searched for codes and received the P0500 can this have anything to do with the tranny issue? I know what the code stands for. Thanks for any help

@notlimah just a quick side question so not to get off topic. How do you like the Dynamic Stage 3? I am currently saving for a trans. Firepunk is close to me, but I am considering Dynamic.

I have a 99 2500 with automatic Transmission that was just rebuilt and a new two disc tc. The first time I drove it after the rebuilt the transmission shifts quickly from 2nd to 3rd to 4th(O/D). It doesn’t happen when your foot is really in it but when you accelerate normally it jumps up and the engine bogs down. The transmission guy that worked on the truck told me it was an electrical issue on the APPS sensor but I want to get some other suggestions before throwing money at the wrong problem. Also the APPS sensor is a few months old

Kind of an obscure question, as I was looking at the wiring diagram for my truck. (see link) @Dynamic If you have any input here... I would appreciate it. I am trying to figure out why the trans relay is in line with the alternator field. If you look at the PCM on the left side, about mid way down you will see a GEN FIELD DRV, in dark green. This field runs 100hz AC to the alternator from the PCM causing it to charge. Lower you will see a GEN FIELD OUT, returning from the alternator to the transmission relay. Why would they do this? Why not run the signal for the trans relay directly to the relay? Why allow the non steady state voltage reg…

I read a while back somewheres that there's a resister you can put in to allow for higher trans pressure from aftermarket valve body and torque. Does anyone know where I can get one and instructions for install? Thanks, Donald

Is there a torque sequence and value for putting the auto tranny pan back on after servicing? Thanks.

My buddy that I go drag racing with has a 98.5 with a 47RE in it. After racing this past weekend he asked me when does my converter lock when I'm going down the strip. I told him that it locks between 75 and 80 MPH. He was suprised and said his didn't lock until he wa about to cross the 1/4 mile line at around 94 MPH. He also said when it does that he's only dropping about 200-300 RPMs. Does this sound like he has a problem, and if so can the shift point be adjusted?Thanks in advance for your vast knowledge!

i have o2 3500 47re was working great no problems was hooking to my trailer, looked and need to move just a little, pulled up, and then it would not shift back to revears. binds up shifter, idicator came back to drive but no farther, i unhooked sheft lever at transmission, shifter went freely back to park so i could turn key off, at first i could shift low second and drive by hand at the trans. that is as far as it would go. after i shifted it a couple of times. and tryed a little harder to see if it would jump past whatever was holding, it,. now lever moves freely, anyone know what i might find when i drop the pan, is their any common shift parts that fail inside, any he…

Ok. I'm new here and have an issue I've been stumped on for 2 months. I bought a 99 24 valve that was a 5 spd truck, it came with all the automatic stuff from another 99. I have everything installed and all is good except the PCM. The PCM is the 56040199 which is verified a 99 automatic PCM, however when starting the truck, it acts like a 3rd gen with a transponder key. It starts, runs for 3 secs and dies.... It did that 3 times and now a no start and I know 2nd gens didn't have a transponder key. It has full communication with the obd2 connector but no CEL's and now a no start. I "borrowed" the PCM out of my 00 which starts, runs and drives the truck but I have no commu…

Noticed that my seal was leaking and was looking for a little insight of fixing it i have never done one. The videos I found where for Fords are they both about the same process on change it.

When i am running on the highway @ 45-60 mph with my edge att. box on 1 or 2, (do not have VP pump tapped) and push the pedal down even slightly it seams as if the trans or T/C is slipping. It feels exactly like a clutch slipping in a Manual Trans. mabe not as violent. does not do this running on stock level. T/C was replaced by local Cottman shop w/ what ever brand they carry, was suppost to be HD good for 800ft/lbs torque. Is this a T/C lock-unlock eletcrical issue???

ok about to pull the transmission again ....i think i broke third gear ....looking to see if anyone has any experience in rebuilding a nv4500? i figure that its got to b cheaper than a rebuilt one ...best price i have gotten so far is $3400......also sorry for the long time between posts but between the army and the new job at kenworth truck company I havent had much spare time till now......thanks alot gang

ok need some help here please ......I replaced the clutch and flywheel this past april on my beast ......put in a south bend ....and everything went great until yesterday ....now the truck acts as if the throw out bearing is not completly disengaging the clutch ...ie synchros raking ....stick hard to push into various gears especially 3 rd and reverse.....any ideas other than tearing the whole tranny back out?

My buddy asked me if i knew of a product that would help him, and his transmission have better performance. He is having problems with his truck burning out, and said there is some kind of load management system on our transmissions that doesnt allow us to rev up enough to light them up. I heard advertisemnts of top speed eliminators and a smarty doing something for the tranny, but i dont exactly know what they do for it. Does anybody got a clue on this subject. Thanks for the info!!!

Heres the new dilema with the wifes truck. The darn transmission wont come out of first gear. I got first, reverse,park and neutral. Is there a electronic part in this thing that could make it not shift into second and third. She doesnt haul anything, Im trying to figure this one out. Would changing the fluid and filter help?? Any suggestions on the shifting problem would again be helpful!!!

I was driving down the road last night and heard a big bang. I thought by the sound that I hit an animal. The truck seemed to loose power after that. Today I noticed that there is tranny fluid coming out the front of the tranny by the torque converter. Can anyone give me some insight as to what could have broke or gone wrong.

I have a 01' 24v turbo 2500. Recently I have noticed that the truck does not want to shift at or around the 20 mph mark. I can press the accelerator down and the rpms go way up but no shift or increase in speed. But, if I take my foot off the accelerator , as if I were shifting manually, and then press back down it shifts fine and speeds up, rpm go normal and the succeding shifts are fine as well. Any ideas?

Well life officially sucks again ....the transmission started acting funky last night on the incredible hulk ...ie not wanting to go into second gear ..my normal takeoff gear ..raking bad in third and the only way to go into reverse was shut the truck off put it in third then restart ...so no hulk for me for at least a week the local shop guy says 1500 for a rebuilt five speed ..but he might b able to crack mine open an fix it for about 900 ....any thoughts or ideas ...on price and what might b wrong :banghead::banghead:
