KEEP YOUR AUTOMATIC CRANKSHAFT! Little known fact, if you try to put a T56 behind an LT engine that had an auto behind it, you need to replace the crankshaft! They are not machined for the T56 input shaft! However, where the LOJ Pilot Bushing Installs is compatible with BOTH LT Manual and LT Automatic crankshafts!

This is simply the best 6-speed option for your Chevy Truck or Hotrod next to the T56 transmission! The 2005+ Nissan Frontier 6-Speed Manual Transmission shares its architecture with the robust Nissan 350Z CD009 transmission (The 350Z transmissions have been proven to hold 700+HP). However, the Frontier version is in a case that makes it much better for swaps into classic muscle cars and trucks. Why? Because it has a top-mounted shifter instead of a remote shifter, and a bellhousing large enough to accept a clutch and flywheel assembly that is the same size as a stock LSx application. 

The LOJ Conversions Gen III/IV Small Block Chevy (LTx) to Nissan VQ40DE (2005-2015 Xterra / Frontier) Manual Transmission Adapter is the first of its kind produced for the LS Swapping community.

      Frequently Asked Questions:

      • Will this kit require any modifications to my transmission?
        • Yes, a small reinforcing rib inside of the transmission will need to be removed to make clearance for the LS Starter snout. This will not effect the ability to use this transmission on a VQ40 again at a later date.
