LML Transmission Tuning

-Second gear converter lockup

-Increased line psi to help hold the power and overall trans life

-Shift points refined

-Optional shift point adjustments for those with bigger turbo setups.

Our trans tunes can be installed with one of our PPEI AutoCals OR any V2.

 

DISCLAIMER:  If your trans is already hurt - it needs to be built. We also can not guarantee that you will not blow your trans... ANYTHING can be broken and stock components still fail!

 

2011 - 2015 A50 TCM Tuning

The A50 Allison follows a pre-determined torque model in which all factory LML Duramax’s follow. As throttle input and load increases, so does the calculated torque the TCM estimates. Following this estimated torque amount, is line pressure. Line pressure in factory form is PERFECT for a factory tuned engine, however, once torque is increased with tuning… The predetermined torque model is higher than what the transmission estimates and results is lower-than-needed Line PSI. With PPEI TCM TUNING, we increase the line PSI to a torque model like it would have come with from factory – Which gives the transmission the line pressure it needs for the torque increase of the tuning.

**PPEI TCM Tuning - We recommend this for all A50 controllers. It has an aggressive Line PSI slope which will model a torque curve 100% above stock. The line PSI is modified in such a way that the truck will still retain good mileage, yet hold high line psi (Close to 245-300psi under full load) following this torque curve. Line PSI is increased higher across the board, so as a result, mileage may be a little lower in some cases.

2015.5 - 2016 T87 TCM Tuning:

The T87 Controller follows a pre-determined torque model in which all factory LML Duramax’s follow. As throttle input and load increases, so does the calculated torque the TCM estimates. Following this estimated torque amount, is line pressure.

Instructions for install:

  1. Verify your LML indeed has a A50 (2011-2014 and some 2015’s) or the T87 (2015.5 - 2016)
  2. Read out stock A50 or T87 file using your AutoCal or V2 before installing PPEI transmission file.
  3. Full Flash in PPEI TCM tuning.
