I came across this on another forum and thought it could be useful. If it is, maybe it could be made sticky:

This is another one that should be in there if we don't already have it and I don't remember seeing anything like this. That is quality diagnostic info for sure. Nice finds Ram15002ndgen.

 

.. it describes everything execpt what my transmission is doing .
I've found a ton of useful information on here about what to adjust and how to adjust it, but never why.

No clarification on which thing to turn if it does this, or what band to tighten if it does that, until this got posted. And this post covers a Lot of what if's,, but I didn't see mine on there.

I have 2ndGenDurango that runs great, looks good, everything's in perfect condition Except,,, for the 2-3 shift.

It won't 'catch' unless I take my foot of the gas pedal a little bit and let the rpm's fall back to around 2000.

This only happens under moderate to heavy acceleration.

If I drive it easy, it engages and shifts just fine.

It doesn't slip in any gear After it engages in that gear.

But getting 3rd to catch, is almost like driving a manual transmission.

Run it up to the shift point, when it starts to go into 3rd, take your foot of the gas, start getting back into it after it falls to 2k rpm.

Did I explain that well enough ?

I'm just trying to figure out which band to adjust which way. That's it.

Has anyone else experienced this 'gears not engaging' thing too ?
Did you find a way to fix it?

thnx

thats the transducer and the governer pressure soleniod...mine did that for the ten miles it worked before failing all together....if you take it to autoizone and put it in a code reader you'll know more...(likely a 1741 code)

I saw that same chart when I had my issues....comes up when you use google....even bookmarked it. You probably should have referenced where you got itor who wrote it btw, to avoid plagiarism (I know I know, corny...But I seen a kit car site get shut down once because of a bunch of pics posted that they plagiarized ) And if you wrote it you'd want credit too right?

 

I didn't post that chart it was a quote from a previous poster who did mention getting it from another forum but he didn't say which one, so me referencing his post as my source again, as my post was a reply, would be kinda redundant and just as useless, again.
Stop.
Repeat.

But thanks for the heads-up, I'll check into that Transdohicky and Guv'na Thing.

Maybe this has been covered, but I can be an idoit. I have a code P0750, and I have to get this fixed so I can register, and get my tags. Any help please?? I have been told that this code is Shift Solenoid (P0750). I have also heard this called by the dodge dealer is a Solenoid package ( whatever that is?) To buy this part from a dealer is is $330. I hoping that it is something I can do my self, but sure, because I don't even know where it is. Which leads me to my next question. Where exacatly is this located????? Please help. Thank You I would love to start driving my truck again.

 

thats great but i dont see my problem on there. when i stand on it at highway speeds it kicks into neutral. and sometimes when i put it in park it rolls.

i'm having same issues and am under the gun to resolve it. i purhased a kit that replaces the poorly made solenoid and plan to replace governor sensor as well. I have the following dtc's 138,141,622,743,748,1757,1762,1765.
I think some of these may be due to my tcc switch that was installed on my truck before i got it. guy said it saved him gas and the nuisance shifting issues dodges have with the least little hill etc. i forgot to disengage it a few times pulling of the highway. Any input would be appreciated. I have the code info i was just wondering if anyone sees a pattern other than the governor sol and sensor.

 

Well fooey!

Truck '96 Ram 360 auto 2wd, 130~k miles) has been making a "growling" noise non-engine speed dependent, good shifts (slight week 1st gear shift) and has been getting louder...changed the fluid when I got the truck and made sure I put in ATF +4, and pulled the return line and flushed an extra gallon of fluid thru the torque converter [aka dumped 2 gallons of old fluid, full system flush with fresh ATF +4])...no real heavy debris in pan, the standard small flakes (looks like wet anti seize)

Wife to truck to a reputable transmission guy and he says the transmission is shot and needs rebuilt...ARRRGH, I told the wife I wanted to try this 1st

http://www.transmissionpartsusa.com/...47RHE&CartID=1
SC-46 47RHE Sure Cure Transmission reconditioning kit, pull the check valve deletion and tighten the bands.

I would rather do a couple hundred dollar fix than a $2000~ fix!

Suggestions?

 

That won't fix your problem. You need to open the tranny up, see what the problem is then fix it, ESPECIALLY if it's the planetary gears.
