I had the same problem with not shiftig out of 1st on my 99. The first time, it was the transmission speed sensor (side of tranny where you'd expect a speedo cable to hook up.) the next time, it was a speed sensor in the rear differential. Seems both are cheap plastic magnetic pickups that easily go south. I was told that the computer reads data from both sensors and in addition to controlling the speedometer and providing input to the rear ABS, the computer uses that "data" as input to control the upshift. When the two sensors disagree the computer falls back on cable position and internal pump pressure. (or at least that's what the tech told me..) That's may be why as long as you keep your foot down, it won't upshift...

every R/T I've ever heard of does this, it's intended to be a protection for the valve train, to cut off fuel so you don't blow a valve spring, but god its friggin annoying. Governor sensor, speed sensor, same thing, they suck. break easily. KRC performance supposedly sells a aftermarket Computer that overrides this, sounds like a decent otion, for 150 bucks instead of constantly replacing the SS. I was thinking that maybe a shiftkit might work too, by enganging the 1-2 shift faster and firmer, it'd also lower the shift RPM also......

So this problem that everyone has is fixed with the governor pressure sensor or whatever sensor? Or is this something I can fix with a flash computer programmer? If this does this on all r/t's then is the sensor bad at all? Or is this the setup of the truck from the factory? One thing I have learned from personal experience and from this message board thread is that the dealerships are usually not as professional as they should be and half the time just throw parts at a problem's symptoms rather than truly finding the real problem. Does anyone know the real problem? Or if there is one? Other than just the annoying setup...

yea dude the governor pressure sensor (speed sensor) in your tranny is reading wrong...its like...$100 at the dealer for the part and i dont think it's covered under any warranty, however some people say installing a shift kit overrides the speed sensor problem so i dont know which one would be worth it.

Oh my gosh this is a headache of a problem... The dealership I took it to is giving me all kinds of trouble claiming this is supposed to do this (not switch at high rps at wide open throttle while it is in drive). He basically is saying if I take it back there is still nothing they can do...I live a while from any other dealer and I dont want to void my warranty with aftermarket fixes. Is there any recommendations? I called the dodge hot line and all they do is call the dealer...It is the classic hassle that I have gotten from Dodge svc departments in the past...

HEHE... yeah the old, stupid rev limiter issue... again. Jesus, you'd think that since R/T stands for Road / Track, that dodge wouldve checked this out first... before SELLING THESE THIS WAY. ok. rant over. anything that you can do to either bring down the shift point, or extend the limiter will work. superchips or hypertech programmers ($400!!!) will allow you to raise your shift limiter, and eliminate the speed limiter (105?!?! what a joke!) but, its 400 bucks. shift kits, and improving the snot out of performance can bring down shift point, but, it can be overall more expensive than a programmer, or a custom flash, AND you'll eventually run into it again...
I've... Ported, polished and cut my runner length on stock intake, port matched TB to intake, Intake and head ports, relocated IAT sensor, 180 thermo, K&N FIPK, auxiallary tranny cooler, andjusted cranksensor to adjust timing advance, recalibrated TPS and TV cable, autolite 3923 plugs, taylor wires, brass cap and rotor, removed stock clutch fan, punched out post cat, and punched a 1/2 inch hole through precats (hehe.. eliminated the cats, but enough is left to trick O2's into thinking the system is working fine!) and each mod, done seperately eliminated the shift issue for a week or so, only to return... NOW with all this done, it only pops up occasionally, maybe once or twice a month on WOT. I'm finally breaking down to get a programmer soon, since I'm starting to get into the exhaust and valvetrain more, and getting ready to start going to the drag track this season, so I guess its time I've done it...

You have an input and output speed sensor, they will both go bad. No programmer or anything will fix the problem. The sensors are bad, so fix them. Forget about going to the dealer, go to AutoZone and pick up the part for $26.00. Very easy to fix, you don't have to drop the trans pan or any of that nonsense. I have replaced both sensors myself. The first time I made the mistake and took the R/T to a trans shop and they told me I needed a new trans. I spent $1500 bucks. Come to find the problem still remained. Turned out to be a $26.00 speed sensor. When the rear sensor goes out, it is located by the rear plunket. You will loose your rear antilock brakes as well. Trust me on this I have been driving my 99 r/t every day since 1999 and have had all the normal problems and still run a 13.5 with no s/c or nos or head work. As for the guy that re located the ait sensor, you must have been on the KRC web site. That only works in open loop, under full throttle you computer is in closed loop and that sensor relocation does nothing at all. I'm sure that KRC has some 50 cent Radio Shack resistors they would sell you for 50 bucks.

I replaced the sensor on the transmission and when I pulled my old one off out came about half an ounce of trans fluid and the sensor had like oily metal shavings on the end of the magnet part... This doesnt sound good to me, what do you guys think? And by the way my truck still does not shift from first until I let off the pedal...

Matt.....at 55k, the tranny in my '00 R/T lost the kickdown band. Along with it were some pieces of metal I found when the pan was dropped. It would rev up really high similiar to yours. While replacing the band, I also replaced the drum as well, just so I didn't have to do it again later. I also talked to Dodge, which was a complete waste of time. They called the dealer, and the dealer was so helpful they told Dodge it looked like I drove the truck hard. This was the same dealer who tried to sell me a whole rack at the same time for one bad outter and one bad inner tie rod, but completely missed that I needed a new front right hub. Yes, this truck has been a POS and I told Dodge this was my 3rd and last Dakota since they were so helpful with this one. It sounds like you may need to drop the tranny and get a look inside. Just my 2 pennies.

Hey guys I have had all sensors replaced and adjusted the cable and those fixes have not worked for me. I have a hypertech pc flash set at 5000+ RPM and now it still floats to around 6 K and will barely switch there...And that cant be good for power,speed or wear on a 360. So any of you guys that had a dealer fix this under warranty by replacing the valve body...please email me and tell me how you got them to do it. If you could email me or post your email on here it would be greatly appreciated.

This really sucks i was looking here for the same info on the trans thing. I have an 2002 R/T and it does the same thing . I have the hypertech programmer and i increased the rev limit by 300 with this sometimes it shifts sometimes it doesn't its very odd i hate it though!

Message:
The PCM will not know what to do whenever the governor pressure exceeds it's programmed max. limit. On our 44/46RE trannies, this limit range is quite low compared to those for GM/Ford trucks. If the pressure limit is exceeded, the pcm doesn't send a signal for the 1-2 shift.
There is a trick using a resistor which will fool the PCM into 'thinking' all is well though. The resister needs to be a minimum of 100 ohm (some use a 150 ohm). The most important part is that it NEEDS to be a 1/2 watt, NOT the 1/4 watt. It took me 7 years before I found this fix.
Guideline instructions are:
Disconnect battery
Unplug middle PCM connector (might be easier to unplug all three for extra room) and remove back plastic clip of middle plug.
Locate pin #31, top left side of plug.
Clip wire approx 2-3 inches from where it connects to PCM plug and strip off a little of each end of wire.
Solder the resister to each end of exposed wire.
Heat shrink the wire you you just exposed; resister and all.
Re-install back of plug.
Plug all plugs back in.
Re-connect battery.
If needed, adjust TV cable one notch in one direction or another to meet your personal preference.
Basic explanation: Pin 31 sends a reference power signal to the tranny. The governor pressure solenoid sends a return signal back to the pcm equal to or less than this reference signal depending on the line pressure. The resistor reduces the reference signal so that the pcm never sees a returning signal higher than what the pcm has been programmed for. HTH.

Message:
If a new governor pressure sensor does not fix it, it's probably a valve body. We have no proof as to what exactly goes wrong with them. We believe they actually become warped. I've worked with Chrysler several times on this issue and have not come up with anything besides "it don't work right so replace the valve body"
