When it comes to optimizing the performance of your diesel truck, Transmission Control Module (TCM) tuning plays a crucial role. One of the key decisions in TCM tuning is selecting between the standard or elevated shift point file. Each of these options offers distinct advantages tailored to different driving styles and preferences. Let’s dive into what each entails and help you decide which option might be best for you.
As technology gets better, we see transmissions in trucks with more and more gears. Recently the Allison 6-speed was replaced with the 10-speed version. For older trucks, this can set them behind the competitors, both in terms of performance and fuel efficiency. A 6-speed conversion kit can take LB7 and LLY trucks to a whole new level of performance and drivability.
If you are already in need of a valve body replacement due to slipping gears because of a weak or bad solenoid this kit is exactly what you'll want to swap in its place. The kit comes with an upgraded valve body combined with a 6-speed TCM. This upgraded TCM comes with updated shift schedules customized to your truck for the new gearing . Calibrated Power has been able to design one of the smoothest shifting 6-speed conversion kits there is. This kit will have your 15-year-old truck shifting like a 2018 model. It's also relatively simple to install and can easily be installed by someone who knows what they're doing in the shop or at home. Another option is to have Calibrated Power install it themselves in one of their upgraded transmissions (DT550, DT750, or DT1000), which is what you'll want if you're trying to make big power.
If you're looking for any of these qualities out of your transmission then a 6-speed conversion is for you:
- Better MPG's
- Quieter Exhaust Drone On The Highway
- Smoother Shifting Transmission
- Engine and Transmission Longevity
- Narrower Cruise Range to Meet Emissions Requirements
What crashes an LB7 and LLY ECMs?:
If you have a 2001 - 2004 (LB7) or 2004.5 - 2005 (LLY) Duramax and have been thinking about tuning it, this article is for you.
As you're probably aware, ECMs have some small risk of crashing during a tuning flash. Browsing the forums online you definitely already picked up on the fact that the LB7 and LLY ECMs are more suscepitble to the issue.

How does Allison 1000 TCM Tuning help with towing?
TCM Tuning is the modification to the programming calibration of a Transmission Control Module (TCM). Ever since 2001 when the Duramax was first offered in the 2500 and 3500 GMC and Chevy HD truck it has been paired with the Allison 1000 transmission.
These trucks are designed for towing and if you use it that way, you can probably think of a few ways you would like your transmission to act differently. That is where TCM Tuning may be able to help.
Common Complaints About Stock Transmission Tuning:
- "When I try to pass and I am in 6th gear, it is very reluctant to downshift."
- "While merging on the express way it seemed to take a long time to get from one gear to the next. It's even worse with a trailer on."
- "Even with tow haul mode on the truck doesn't seem to shift well since I put these larger tires on."
