DURAMAX-POWERED PLAYTHING

I’m presently considering repowering my 6.2L diesel-equipped Toyota Land Cruiser with a Duramax. I have all the oily bits sorted, but I’m looking for advice in solving the electronics portion of this puzzle because I’ll be retaining the Toyota manual transmission. Seems I can only locate the electronic components for a powertrain that included the Allison transmission. I’m sure that the parts I have located won’t work correctly with a manual. Also, can you recommend any parts suppliers?

Patrick Carmichael Queensland, Australia Through 2005, the Duramax-powered trucks were available with the ZF-S650 6-speed manual transmission. You’d just need an ECM that is programmed for a manual-equipped truck, along with the related wiring harnesses for a manual-equipped truck. If you cannot locate a set of used wiring harnesses, you should be able to buy them directly from a GM parts dealer. Any Duramax engine from 2001-2005 can be used with a manual transmission, whether that engine was originally used in a manual or automatic transmission equipped truck. The EFILIVE programmers advertised here in

Diesel World can help with programming if you cannot locate a factory ECM programmed for a Duramax/manual transmission. Alternately, you could contact PPE Diesel (Ppediesel.com) and ask about their standalone wiring harness and computer kits. They aren’t cheap, but they can simplify a Duramax installation for those unique types of conversions. Keep us posted about your progress. We’d like to see it once you’ve finished.
