Confirm Crossmember Location Exhaust Routing And More in Your Allison 1000 Transmission Swap When it comes to popular engine swaps like LS swaps Coyote/Godzilla swaps and Gen III Hemi swaps most builders opt to update their transmission at the same time. Let s face it who wants a modern fuel injected engine with a notchy old four-speed behind it? Especially when you can run a stronger manual or automatic transmission in the tunnel to support your increased power level and still make it look old school cool with a period retrofit shifter of some sort. The typical 5- or 6- speed manual or automatic transmission found in the same donor car as your engine swap fodder is usually the best place to start for adding a modern transmission behind your swap engine. The Allison 1000 electronically controlled automatic transmission found behind GM s Duramax diesel engine in the Chevy Silverado and GMC Sierra pickups from 2001-2019 has become one of these popular modern transmissions to swap. Part of it is the torque capacity at well over 600 lb-ft of torque capability and the other reason is the standard GM V8 bellhousing pattern it uses makes mounting it to a GM V8 a bolt on affair. Even the torque converter bolt pattern makes life easy as the Allison uses the 4L80-E six bolt pattern. Of course there are several adapters available to fit the Allison 1000 transmission to other engines as well with the Cummins to Allison conversion being one of the more popular options. The 5-speed Allison transmission was used in 2001-2005 models and featured five forward gears (5th as an overdrive). The 6-speed Allison transmission was used in the 2006 and up Silverado/Sierra and was upgraded to six forward gears with double overdrive. 2010 saw a change to the output shaft so most swap enthusiasts utilize the 2001-2009 versions of which use identical transmission cases. Being electronically controlled you will have to use an Allison 1000 standalone controller to handle shifting just like any modern electronic automatic you may use in your project. Traditionally building something with a transmission that was never meant to be installed in it would require the actual transmission a floor jack or transmission jack and a spotter or two keeping things in check while measurements were taken parts tack welded and so forth. It s not an easy or quick process and it can be dangerous with a 300-plus pound Allison 1000 transmission being carefully balanced on a floor jack. There is a better and safer way to mock up your Allison 1000 transmission in your project and that is with the patent pending Speedway Motors SoloSwap® steel Allison 1000 mock up transmission. Laser Cut Steel Plate for Strength Simplicity and Easy Storage Unless you re a commercial shop doing a lot of transmission swaps it is time consuming and complicated to disassemble the Allison 1000 transmission down to a bare case to shave enough weight to make it manageable for fabrication use. Most enthusiasts are using a good used Allison 1000 transmission from a Duramax powered Silverado for their project and the last thing anyone wants to do is crack it open and mess with the magic inside. Using a replica transmission to mock up your transmission swap for your project is much safer and your back will thank you for your efforts
