Product Info: All gearboxes will come thoroughly washed on a wooden pallet WITHOUT oil in them because of shipping requirements. The NSG 400 is a very tough and custommers have it on cars with more than 600hp running for a few seasons without issues. These gearboxes fit all V6 and V8 engines from 1998 all the way to 2015. As of our knowledge they are direct fit to all m112, m113, m156, m272, m273 and om642 engines. NOTE! All gearboxes are from scrapyards and not being rebuilt. Buying a gearbox does not guarantee you gat a new rebuilt item that will outlive your build.
