Would that be the same pin and color wire on a '02 model?
I'll give it a try!

alright guys, i tried it! i disconnected the wire and it definitely firmed up the shifts. it chirped second pretty good and felt like it wanted to chirp third. i didn't burn first anymore than i did before. i noticed one thing though. when i got to speed limiter(about 97mph) i'm usually still in third gear. well, now it shifts into forth at about 95mph. i felt like it was still going. i had to hit the brakes cause of traffis on the interstate, but i think the speed limiter might have went away. is it possible that the torque limiter and the speed limiter could be tied in together. i'll try it again and let ya'll know for sure.

Good Job!!!!
Every little bit counts for the goal of getting our
4.7's into the 13's NA. That should knock off a
tenth. As far as the speed limiter is concerned,
if you come up on it real fast, you can get it up
over 100 before it cuts out.

the speed limiter is still on. i went back and hooked up a toggle switch, so i can turn it on and off. i raced a 318 single cab tonite. it has the mopar perfomance 318. it's pretty fast. he says it runs 14.2 with the slicks, but i whipped him by about a whole truck length. i was suprised big time cause i saw him beat r/t pretty bad.with the wire disconnected it felt like a double clutched second. hopefully the cams and intake i ordered will come in this week so i can whip some more ass.

Some guy refered me to this thread as a joke I think.
But this sounds tempting. However when my '03 4X4 4.7 Auto busts the tires lose it sometimes rips them all the way up the street. At times it has done this when pulling out in BUSY traffic when I would much rather it just hooked up and took off. I dunno if this is for real or not but I would like the shift to be harder when I'm really on it. A tranny shop a while back told me that when the tranny shifts it actually RETARDS the spark timing to back off the power a tad. Seems that some people don't like the neck jerking shift at full throttle!
If it works on our trucks, I need to do this to my FWD Chrysler as well!

Did this fix this afternoon and it certainly made a difference for me. First of all the wire is a yellow wire with a green trace (stripe). It's not dark or light green, just green. The module that it is plugged into that has a yellow/green wire going to pin # 10 is the module to the left of the radiator.(looking at engine).It's easier to remove the airbox and using the correct size socket , unscrew the retaining nut and the connector will slide back from the base. Pull the end back under the bracket that holds the cruise control unit and carefully remove the tape from the connector. Once that is done you can peel the plastic tubing away and there are the wires. Find the yellow, green trace wire, cut it and insulate the ends. Put it all back together. Before I did this the gear changes were taking longer (it felt like the change was sliding through.). I originally thought that the change was taking too long but was in fact the sound of the engine retarding. I had a shift kit in my 95 GT Mustang that was a hard quick shift and this fix is almost as good. In fact the gear change now is what I would have wanted had I put a shift kit in. I will keep you posted if anythin related to this modification comes up.

Graphite,glad your looking into this. I kid around with you but do respect what your doing.
Allan, How is the drivability? I would like mine to shift firmer but not if it`s slamming the drive train around. No check engine light?
The dealer flashed my truck for hard up shifts. It would slam the drive train if I accelerated into traffic then slowed down. The trans would up-shift while I was slowing and bam.(the flash worked well)
Does anybody know if this mod would nullify the flash? I assume it would if the flash modified the torque management. Could they tell you messed with it by checking the computer memory?

jeremiah,
The only difference that I could feel was probably only the engine not retarding. In fact it could still be a little harder. But I was used to my Mustang banging into the next gear. But I did not want to have another car that changed that hard again. No drivability problems. No check engine light. My question is is that wire the signal from the TCM to the engine(PCM) to retard. If that is so, are there any other situations where the TCM would request that the engine retard? If this was done in the RAM's was it done the same way?

ok testing is complete, most definately shifts much harder than with the pin in. but! if you want a good 1/4 run you have to manually shift it and have the od off to get to speed, with it on and in drive, it shifts hard but tooooooo early in 3rd and at 75 into 4th.it does not kick down into 1st from a 20 roll like it used to, it doesnt kick down into 2nd from 3rd at 40 like it used to. if you manually drop it down as you smash the gas it shoots out like a beast... my suggestion hook it up to a switch so you can turn it off for the launch and 1st -2nd shift then kick it back on and let her go. i must say i did leave a nasty 2nd line when i went from a stop and manually shifted up to 2nd.. i really liked that!!! hope this helps..

OK. I Took one for the team!
Someone was refering to a TCM and it being seperate from the PCM and that it was just forward of the PCM.
This does not seem to be so on my 2003 Dak 4.7.
So finding a PIN 10 isn't that easy.
Anyway. There was a Yellow wire with a Green stripe coming from the PCM. SO I spliced into that. Then wired it so temporarily into my cab.
So I took a drive to test it. I unhooked the wire from within the cab while cruising at like 30 and immediately the CHECK ENGINE light came on. Also I no longer had 1st gear. Damn! As I drove it more I noticed that it started in 2nd. WHen it shifted into 3rd I could only get it to downshift into 2nd if i pulled it down and it did HARD. If I'm off the gas at 35 MPH or so and pull it into 2nd it BARKS the tires from the instant downshift. Hmm... ANd when I get on it it shifts a lot quicker into 3rd but it's still wacked.
So, the test kind of failed, but sounds like we're ont he right track. It DID shift from 2nd to 3rd HARDER and alot QUICKER.
So, I drove home, unplugged the battery to reset the PCM. Hooked the wires back together and watched it on my voltmeter. When stopped you're sitting at 12 VDC (13.8 on the meter). I noticed when you are NOT on the gas much and it starts to downshift the voltage goes to 0.
Anytime you gas it enough to downshift or hold the gear longer, it goes back up to 12 Volts. Hmm... I'm curious to try a mod to hold it at 12 Volts to see what happens but I've got to be very careful.
This may be a waste of time, but I am curious as sh*t now. Our Chrysler Cirrus does this "retard at shift" too and I hate it.
Sooo. back to the drawing board.
But here's some PICTURES as always to show what I've done.
Anyone in here who has ALLREADY done the mod, what year was it? Mine is a 2003, nothing looks like the TCM you mentioned before. I may have a different PCM as well.
I sure did go thru a LOT of work. I did this as if it was going to be PERMANENT. This was the 1st mod in a long time that didn't work the first time!
My PCM.
I found this wire going to the PCM. It's the Yellow wire with the Green stripe.
I cut it. Soldered in a roll of twin lead wire so I can open and close the circuit from inside the cab.
I even shrink wrapped it.
And hid the wires in the wire loom where the dealer would never see it.
And ran the wires into the cab.
Here's the trouble code I got if anyone who has the list would care to look it up for me.
And here I am watching the meter as I drive. HArd to do while driving by yourself!
OK. I'll mess with it some more, but I don't have much time today damn it.
Those who did this, compare my pics to your truck and let us 2003 guys know if this is different.

Thanks Andrew. I knew WHY the colde came up. Just didn't know what it was. It always went away when I cleared the PCM by disconnecting the battery.
I swear, next thing I may do is to find the main power to the PCM that I can switch off and on from with in the cab so I can clear the codes any time I want without getting under the hood out in public LOL!
Anyway, since I went through the trouble of connecting the wiring like I did I went thru some more trouble to experiment.
I brought the wiring into the front seat like shown above. Then I experimented with the signals.
The signal seems to stay at 12VDC at a stop. It goes to zero when crusing. When you gas it and it downshifts it goes back to 12.
So I tried holding the signal to 12VDC a little longer manually. Funny a$$ sh*t here. I used a allegator clip to junper the 12VDC to the pin then took off full throttle with the tranny kept in 1st. I hit approx 5000 RPM's when it shifted out (even tho the tranny was selected to 1st) and barked the ever living sh*t out of my tires!
But, it threw that trouble code and every time it does it is in some sort of LIMP mode and starts in 2nd gear, shifts into 3rd and never goes into 4th.
So, then I grabbed my small box of electronic parts and drove up the street.
I made a small circuit with a transistor, resistors and a capacitor. I built a very simple circuit that basically would delay the signal from going from the 12VDC to zero by a fraction of a second. I experimented with different cap values to change the timing and it DID HELP reduce the shift time. The change in the exhaust as it is retarded was less but not gone. If I caused the delay to be too great it would throw the trouble code. Each time it does this I have to pull over and clear the PCM. That sucks.
Anyway, I'm not even sure if it is worth it or not. If this was a regular cab 2WD and I DRAG raced it WOULD be worth it.
But mine is a 4X4 QC and I TOW so I think this mod I may leave alone or perhaps make a switch to change modes. I still have the wires zipped up under my dash for later.
I hope this helps anybody interested, and if anyone knows more about the 2003 wiring let us know.
