Upgrade your truck's transmission tune in order to support added power from an ECM tune, and improve shift points and performance.
You must send your stock TCM file read to sales@dieselpartdeals.com after ordering and include your order #. Please also send us your MPVI3 serial # when sending your stock file.
Product Notes:
- An unlocked HPTuners T93 TCM, HPtuners MPVI2 or MPVI3, and 4 HPTuners credits are required to flash the 2020-2023 L5P TCM.
- Once you receive your new TCM, follow the “Replace TCM” function in VCM Scanner. See instructions here. Then, license the controller and start tuning! If you do not follow these instructions exactly, your truck will throw codes and will possibly be in limp mode.
- After doing the TCM swap, perform a read on the TCM ONLY (do not include both ECM and TCM together in the read) and send us the stock file.
- You must ALWAYS use the latest HPTuners BETA software and resync your MPVI device (HPtuners VCM Editor BETA -> help->resync) , download the latest BETA here
