This is not a cheap swap, expect to spend a minimum of $2500 plus whatever the rebuild cost you.Ĭurrently there is not a transfer case adapter to fit the NP205 transfer cases. I guess for most cost is going to be a concern. It is all handle by clutch to clutch switching. There are no clutch bands in the 6R80 like the C6 has. In stock form can easily handle 500-600 HP with a good quality rebuild and improved clutch discs. You can use a 2WD model with just swapping the tailshaft housing as the output shaft is the same.ĭo not think of this transmission as a weak late model transmission.

Naturally if swapping into a Bronco you would be looking for a 4WD model, but don't worry if you can't find one. So far my research has turned up the following donor vehicles. Salvage yards may want a premium for a late model one. No you might not find one in your local Pull-A-Part or LKQ. These transmissions can be found in a variety of vehicles. The 6R80 torque converter is a lockup style and aftermarket convertors are available with multi-disc lock up. First gear is lower than what the C6 or AOD would offer and about the same as the ZF5.

Hoping for something around 2000-2500 rpm. The 6R80 has a double overdrive so engine rpm can be lower at highway cruise speed. Besides my old legs and hips just can't handle city driving with a manual transmission. Currently my plan was to use a ZF5-47 manual transmission, but behind the modified Big Block Ford I think it's life would be short lived. I have been considering swapping to a 6R80 6 Speed automatic transmission. If mods think it belongs elsewhere please move it. Not really a section for this so chose to post this in Nobbie section.
