Picked up and installed the MP TCM this morning, before work, at the dealer 40 minutes away from work... then drove to work.

Mopar Performance Transmission Controller (TCM) - Transmission Control Module - Part Number : P5153332

Comment on the experience:

UN - FREAKIN - REAL

More later, when I am not at work.

I agree... :wtf:

It's not right I tell ya!! spill it!!

Beans are good... LOL.

After installing it, and going through the TCM "Learn" procedure (You know that the manual says to do 10 minutes of driving without WOT, going from 0-65 lots of times to get the adaptives set?)

Okay.
Spill.

I don't get "odd" torque management bits anymore. the engine always feels like its trying to make as much power as is requested, at all times.

Autostick: Anytime I am under 23-ish MPH, OR, anytime the RPM is below about 1400 rpm, the Torque converter is UNLOCKED. anytime those conditions are NOT met, its LOCKED SOLID. EVEN against the stroker. not a hint of slip. I can be driving 55 mph in 5th gear, go WOT, and my RPM won't change: the engine will bog against the locked trans and try to accelerate. I can slap the stick to the left, get a shift to 4th gear, and it will shift DIRECTLY to 4th, it WILL NOT act like it unlocks (it will nail the 4th gear 1:1 rpm, and not move until the car starts accelerating). Same with 3rd gear. Shifting in autostick is constant, quick, and very reliable. I DID hit Limp mode in 1st gear, but going into limp mode is no longer a "BANG" just kinda... a wimper. I dont' like it. It probably then, means, it has something to do with the ECM. (which ya'll might have known, but I just didn't for some reason).
Shift Hammer now will be a good addition to the car, as autostick is pretty much a stick shift that you don't have to use a clutch.

"D" Drive: Drive is MUCH better. it is "weird" compared to before. The engine does NOT bog when stalling against the converter in first or second, and hooking up anywhere is hard to do. The "Weird" part is: The converter "Locks" in every gear as it drives, but it unlocks on shifting. Accelerating to 55 feels like there is 7 or 8 'shifts' in there. While thats feels weird, it doesn't jolt you around, and everything seems like it SHOULD be there. I have a feeling my 3200+ stall converter is responsible for all the torque converter... behavior... but I am not complaining. My dashhawk says the trans temp never got over 165F.... so... okay, right?
Shift is crisp and a good kick in the butt compared to the other trans computers... I wonder what a B&G with all TM removed would do... probably knock the head rests into the back seat.
MDS in "D" is very odd. It unlocks the converter in 5th gear, but then its like it doesn't know what to do, so it lets 4cyl drive unlocked for a little while. eventually, it locks the converter again and all is good, cruising along is nice. Same thing happens when it kicks out of MDS back into 8cyl. It seems to have been getting better at the transition with more miles.

Shifting from "P" to "R" or "D" is fast, and like it should be in the first place.

Okay. Start asking questions. I'm off to a party so I will answer when I get back. (Can't say the answers will be good tonight, though...)

TCM's that I have tried, and how they compare:

Note: All TCM's that I have tried so far have NOT liked my 3200 stall converter with the engine in front of it. ALL requested torque management, always at inappropriate times.

Stock '06: Shift points are blah. (5700) Torque management and shifts are blah as well. torque converter lockup at part throttle behaves poorly and jolts the car.
Updated '06 (AKA, "new SRT"-ish stuff that everyone likes more than what came with their car): Shift points are *better* (5700), and it seems to "learn" how to be a good driver a little bit. Still poor Torque converter control.
Heat Stage 1 TCM (Un-updated 04 computer I think): Better shift points from the start, (5700) but it smacks rev-limiters on shifts and still has torque converter stall issues.
Updated '06 + superchips: Better Shift points. (6200-ish) Better shift quality. Doesn't smack the rev limiter in "D" or "Autostick". Torque management is especially bad... (Like.. REALLY REALLY AWFUL.) Shifting gets only a little better with time
Heat Stage 1 + superchips: Excellent shift points. (6200-ish) Better shift quality. Doesn't hit the rev-limiter in "D" at WOT, but will hit rev limiters at 3/4 throttle (weird). Still bad Torque management. Shifting gets better over time.
Fast56K flash: Excellent shift points. Excellent Shift quality. MDS seems to transition smoother too. Autostick got changed, seems to drive like a "standard R/T" (no "5", and will get a downshift when in a gear). Driving more DOES get better shift quality also. Torque management is all over the place, at least for the higher-stall converter, unfortunately.

So, first off: the Mopar TCM is my favorite so far, for all applications, save the weird MDS thing when cruising on the hiway.
The Fast56K flash is GREAT for daily driving and the dragstrip in "D", but Autostick experience is quite diminished.
The Stock computers with Superchips flashing just don't match up to those two TCM's, anymore. They are better for Autostick than the Fast56K flash, but overall just don't match what I'm looking for.

Now, All I need is to get the Mopar TCM up at 6500 rpm shifts when in Auto-stick, and Have Paddle-Kick.... and also sort out the MDS oddity... and I will be golden.

I've had this TCM for a year now and it has worked without problems. One thing to remember, the Mopar TC is 2400 to 2600 stall(the Supercenter wasn't with one). This may the reason you are seeing the issues.
 
#11 ·
Well, I put mine in this afternoon as well and I have to say I am very impressed so far. The TCM really matches the Pro Torque TC and the gear changes are much more pronounced.....and at WOT it is a solid push in the back, not the slide into 2nd and 3rd I had.

My only comparison is to a stock PCM/with update and Superchips flash.

What is the PN to order this TCM please.
 
#14 ·
Pretty sure its 5.7 only.

It was plug and play, no Starscan needed.

It *may* be possible to get one, and do the "Trans Cal Procedure" in the Starscan, and coding an SRT VIN in there... I don't know how it would react tho, and you may end up with a light-plastic paperweight...

Would this benefit a slightly modded car?
 
#18 ·
It would benefit ANY car.

The *Only* issue I see, is the shiftpoints in "D". you NEED to have your Engine Computer Rev limit WELL above 6200 rpm... I don't know if superchips alone would do it....

This may be a bad memory but I was thinking the Mopar TCM required the Mopar PCM?? Was the PCM, TCM, and higher stall convertor supposed to be a "package" from Mopar? Maybe a dealer was corrupting what was left of my mind. :)

For me auto stick is fine but it seems like in D during normal driving it shifts to fast to get to 3rd and bog and lug just like the others. Maybe it will addapt more I was a little dissapointed
 
#20 ·
Hmm.. I guess my 3rd gear was so bad before that I am happy it is what it is now... lol..

the Fast56K flash DEFIANTELY is better on RPM on that 3rd gear shift, better than anything else I have tried (including the MPTCM), but the Torque management I get is just so severe....
 
#23 · (Edited)
Hmm. The only reason I had not considered one of these was because I thought it would require Starscan (and my local dealer is an ass). So now I'm seriously thinking about it, because even with Superchips' settings, this car has the worst shifting transmission I've ever experienced.

Has anyone here tried the TCM that HHP sells? For whatever reason, theirs requires Starscan...

Ok, so do you need the Mopar TC installed or will this TCM behave fine with the OEM stuff.

How is the Torque Managment - compared to the stock TCM with the flash and SuperChips.

Install is easy? and is it worth the money for those who just have SC tuner and a few light mods?

DaveLeck - if you think the SC trans coding is bad, my guess would be that you need some TCM updates or something. The Trans coding is the only reason I have kept my SC this long. Firm crisp shifts, AK or AH RTM and raised Shift points.. Yummie
