GSM Stage 2 TCM Installed!

[greatone61]

My car:

2006 300C SRT-8 with the mods below. I had the TCM TSB in my car, which with the mods sucked. So I decided to finally try the GSM Stage 2 TCM. Scott from GSM was a Spring Fling so he did a few installs.

My Thoughts:

This TCM is badass in my opinion, especially in autostick (which is what I've been doing alot of). My shifts are a lot better, they seem to be firming up the more I drive the car. There is no hesitation in the shifts at all, those of you at the Rumble saw what my car was doing, that is completely gone. The gears are also holding longer, and are in the right gear everytime I need to kickdown or brake and go. I personally think if you roadcourse or drag your car this would be an awesome addition. At first I didn't think anything of a higher stall with this TCM, but it really seems as the stall has increased.


Props go out to Scott at GSM, this is one awesome product, its worth every penny. Thanks!

Was this the TCM that was a rebadged Mopar part, or was that something different?

[DanRealtor]

Yeah, it's the rebadged Mopar part.

I just ordered mine today.

Thanks greatone61 for your comments on the TCM. I value your opinion.

I will report back after mine is installed.

You'll love it Dan, but now I'm actually afraid. I could hardly keep up with your driving skills before, wtf is this going to do? LOL!

Who did you order yours through Dan? How much? Thanks

[marmaduke]

Also interested in this item? Who? What? Where? Etc...

You can call Ryan or Scott at GS Motorsports, 888-GSM-HEMI.

Just like Dan, your comments on GSMs TCM finally convinced me to order one.

I was hesitant because of the price, but I have the Heat TCM and I don't like the automatic upshift. I also had the TCM TSB done on my stock unit and I feel there is still room for improvement.

You'll love it, I noticed that since my PCM was reset when the install was done it took some miles to notice how well this thing shifts now.

Scott installed my TCM at Spring Festival with StarScan in hand.

I'm liking it more everyday. I'm afraid of autostick a little, my motor revs very fast in 1st. Been compared to a NASCAR motor.

Every TCM is a Chrysler unit. Seimens make them all. Everyone reflashes them, no matter who sells them.

Don't worry, I'll wait up for you! JK

Your car is still faster than mine (at least on the drag strip).

Like all of us, practice on road courses will get you faster and faster. I have run my car at Sears Point (aka Infineon) Willow Springs, California Speedway, and DCX's cars at Laguna Seca and Firebird Raceway. Experience on road courses, there's no substitute.

I also have 1330 hours of seat time in my car. Practice, practice...

Yeah, but one of the companies wasn't doing anything to them other than marking them up... that was my question.

The TCM that the Eng. got was one that had not been flashed yet by GSM, it was also the Stage I TCM that GSM took off the market even before the Chat session had red flagged it....

This is the new GSM Stage II TCM and it works wonders.... Especially on the heavily modded sleds....

I too have recently had mine installed and my shifts are smooth as silk. Before the Stage II my sled would FALL flat on her face going through shifts. Now, woo hoooooooo.... Now more powerband loss going from 1 - 2 or 2 - 3...... It is a great product that works wonders....

Hope this answers your question.

This thing has the Tranny-Nanny still right?

This thing has the Tranny-Nanny still right?

It does not do the auto 1-2 shift in autostick. Shifts firmly at 6,200 in drive. Will go to rev-limiter in autostick or limp mode, whichever comes 1st.
