alright guys im looking at a complete motor & tranny out of a 03 harley and was wondering if & how hard it would be to convert the 2wd 4r100 to 4wd. or could i jus keep my built 4r75?

the motor & tranny come with all wiring, instrument cluster and computer which is why i was wondering if i i could jus keep my 4r75 with the harley computer or easily convert the 4r100 to 4wd

thanks alot guys

anyone?

 

Might wnat to look at a 4R100 out of a Expedition with AWD.

 

If you run the 4r75, you will need to run your curent computer and just have it tuned to run the Harley motor.
This is the way I would do it!
To change the 4r100 2wd to 4X4 you would have to totaly disasemble it, install a 4X4 tail shaft and housing. Then totaly reasemble the tranny.
Plus there is a LONG list of things to change in order to swap from the 4r75 to the 4r100!!!

Sorry yall not sure why I said 4r75.
Can I use my existing engine harness with the Harley motor without having to add anything to it or just be simpler to use the Harley harness?
Also it comes with the instrument/gauge panel. Will it just plug and play in my truck and is it possible to put 4wd indicator lights in it?
Oh and it comes with the fuel pump. What all will I have to do to make it work in my truck. Ive seen in the owners manual spots for relays for fuels pumps an things only for Lightning/Harleys.

Thanks a lot yall! I'm just trying to see how much work this is gonna be before I make the jump, buy it, and am stuck without my daily driver.
