Brand new AC Delco TCM pre programmed to your VIN. Just install and go.

Requires core shipped in advance.

Please note: I did not diagnose your truck. If the new unit does the same thing as the old unit then it's a misdiagnosis, but the transaction is final as there are no returns on electronics once installed.

We keep these in stock and program to your VIN so you can just drop in and go.

Used replacement model A40 TCM module for the 6 speed Allison transmissions in LBZ and LMM trucks from 2006-2008. Programmed to your VIN and stock calibration.  30 day replacement warranty.

The 2009-2010 LMM and 2011-2014 LML trucks used the A50/T14 module. Please be sure to check what your vehicle has in it. It is etched into the case in very fine detail.

These things used to be commonly available, but suddenly in short supply so the price has gone nuts. Standard pickups and vans should use the NEW units. Kodiaks cannot use the new ones so we save the used ones for those vehicles. -JK

This is a good used replacement TCM loaded with the proper file to match the VIN and stock calibration of your 2001-2004 LB7 or 2004.5-2005 LLY equipped truck.

Requires core return. Note: I did not diagnose your vehicle. If the TCM does the exact same thing the original did then odds are you misdiagnosed.

This is the OE Genuine Allison Filter. Fits 2001-present Allison 1000 series. Be sure to transfer the ring magnet onto the new filter!

This is a special TCM file that has been proven to improve track times. We will be programming customer units for exchange, or we can often supply a good used core. It is in no way a custom tune. It is simply Allison programming that we have customized and found to work very well. Shift speed programming runs much like the Tow Haul mode on the factory TCM. Shifts are generally much firmer as the TCC remains locked during upshift and downshift operations. Easily swapped in a matter of minutes. Overdrive lockout will not function and 2001/2 trucks will likely not show the gear position highlight when shifted to OD on the selector. It will be in gear, the highlight will just go blank.

"This TCM begins service with a clean slate memory. It has no adaptive data and therefore will likely shift extremely aggressive until it adapts to your vehicle. Test Driver Pat McSwain (aka McRat) has reported consistent .15 to .20 second improvement in E.T. by simply swapping in this module. He keeps the Kennedy TCM out of service for daily driving and swaps in at the track. This keeps the TCM adaptives nice and crisp and prevents it from picking up any bad manners (lazy shifts) on the street. Brandon Meyers (aka BMDMAX) and myself use this same TCM day today on our 2002 trucks. I also prefer to use this TCM for Truck Pulling in my 2002" -JK

Rugged PML deep pan adds 3.25 qts over stock. Uses standard filter with a built in support ledge.

"The PML pan is my own personal favorite. The drain plug is moderately sized and oriented in the lower front wall to promote complete, controlled evacuation of the fluid unlike others that use a huge plug in the floor with a tiny internal hex drive. -JK

This brace is designed to relieve the stress placed on the tail housing by the transfer case hanging on it. Fits 2007.5-present LMM, LML, etc with Borg Warner transfer case.

"While the number of instances with cracked housings has not been excessive, this brace is an excellent insurance policy." -JK

Fits Allison 1000 with standard/shallow (black) filter. Retains filter eliminating potential for filter to drop out.

"The factory pan and PML pans typically use the short filter. Please verify which unit you have before ordering. We will not be responsible for making this decision for you." -JK

This brace is designed to relieve the stress placed on the tail housing by the transfer case hanging on it. Fits 2001-2007 Classic (LBZ) with New Process transfer case.
