Werks Transmission Tune

Dave just sent the new tune for the GXP charity car and it is really great! Shifts are much cleaner and firmer without all the "wandering" I experienced before (I believe the stock tranny feels worse after a performance tune, BTW).

I highly recommend it for auto GXP's out there -- he can adjust many levels of firmness and shift points. Dave knows what I like, and he seems to have nailed it.

He also gave it free of charge (as well as the intercooler).

Only two small bits remain - Wildwood front brakes and the turn signal not resetting (which will be a warranty dealer fix since they did it once before).

Looks like the car is going onto a local dealer lot, on the showroom floor of a dealer who is a big hospital supporter (Mike Yates GMC/Buick - formerly Pontiac).

Stay tuned and thanks again, Dave and Werks.

Glad you like the TCM tune Sbindley!

Showtime - The tune is easy to install if you have HPtuners or access to an HPtuner device. Additionally you can send us the TCM out of your car, we program it and ship it back to you.

You would need to either purchase an HPtuners suite here - HPtuners interface or you can ship us your TCM and we can program it on our bench and send it back to you.

More info on the TCM programming is found here - WERKSracing TCM Tuning

I have this tune for the auto. Dave tweaked it and I run consistent 13.2's
Eliminated torque reduction and increased pressure.

Before tune, 13.5 to 9, same track, same night.

Recommend it.

Me too

I don't like the way my transmission works too. Just bought it, a 2007 base. No interest in a hot rod. The car will be a daily driver. I just want it to shift better and not wander.

Give this TCM tune a try, you will not be disappointed...

Are there downsides to an auto transmission tune? Wouldn't faster, firmer, or harder shifts cause more wear & tear on OEM gears, possible leading to auto failures?

I think it could be looked at both ways ChopTop. My concern is doing away with something called Torque management in the transmission. What affect would that have. I am not a mechanic at any level.

If it improves the transmission only for a racing mode, most likely not interested, but if it stops the occasional hard down shift when descending down a steep grade I can see the advantage to that. I drive mine on very steep, curvy mountain roads, with climbs of 4K in less than 15 miles and on 74 descents from 6K to below sea level in 25 miles. That is where my auto does the strange things occasionally.

There certainly could be a degradation in longevity of the auto transmission with the addition of a TCM or even an ECM tune. Anytime you modify the drivetrain there are reductions in long term sustainability of the components. With that said we have done 50+ TCM tunes and have not had any issues. We recommend more frequent transmission fluid changes when modifying the kappa drivetrain, not just with a TCM tune but also with any ECM tune that cranks the boost up a lot more versus stock...

While I can't comment on the tune as my car is a manual, I have to warn anyone looking at shipping their TCM to werks that the address listed on their website page for it is incorrect. This was quickly sorted out after I found out my package was unable to be delivered, however I will still end up wasting a week and the cost of shipping. Hopefully they correct this soon as it is incorrect on all the tunes on their website I have seen.

I apologize,

If you can send me a copy of the shipping sales receipt I will offer you that amount in store credit towards your next purchase.


I just changed the address to our new address on the TCM page, sorry again for the confusion!

Let me add, my shifts very normal (soft), unless I plant my right foot and hold it down. If I do, it chirps the tires and completes a very clean solid shift. This and lowering the rpm shift point kept the stock motor in the powerband. 13.2 in Florida's humility is pretty good for a stock car and an amateur driver...

Remember, the shift pressure and time are tied to throttle position, so it is only adding pressure and reducing expected shift times when you need it.

I have had zero issues and believe I was the second tune, Dave correct me if wrong...
