Hello,
I have a 2004 Itasca Sunova 27C Workhorse P32 chassis 8.1L Vortec engine 4L85E transmission.
Can the 2004 4L85E transmission be swapped to a 6L90E transmission? Any info would be greatly appreciated.

Swapping a modern transmission for an older one can be difficult and expensive. Most require a TCM that communicates over the CANBUS with the ECM and other modules. There might be an aftermarket kit? If not, you would likely need a lot of custom work, equipment and programming. Also, a local company here in San Diego makes over/under drives for motorhomes. Check out Gear Vendors.
Has anyone used GEAR VENDORS. There product looks good. Has anyone tried to use GEAR VENDORS multiplier on a 4L85E transmission, p32 Workhorse chassis 2004 27C. Any comments are greatly appreciated.
