I have a 2004 cummins with a 48re transmission and when im done with collage in about 3 weeks i am going to convert it to a 6 speed as a little present to my self...ive done auto to nv4500 swaps plenty of times but never 6 speed with all the electronics on a commonrail....i was wanting some advice on what all i will need to make it work and whether to go with the nv5600 or the g56 tranny thanks guys

 

A new flywheel, the hydraulics, and the tranny and clutch of your choice.

You might have to have the dealer reflash it to complete the switch from the auto to manual, but that's about it.



Oh, and a lot of time and patience.

 

dont forget to over ride your neut safty

 

if you search i posted this swap on here all info ya need good luck

 

Thanks guys very helpful information but is there different harness you have to get rid of or change because of the automatic or anything like?

 

remove the shift cable and tuck/tie up wiring, for reverse lights get the run a power to the on side of the switch on the trans and a wire to the reverse light from the other side of the switch

 

ok thank you red sled

 

I was reading somewhere you have to replace the hole wiring harness and i was wondering if you had to do that?

 

na i just pinned my N safety and wired up reverse thats all i tied up the old auto harness

 

did the same minus the reverse who needs back up lights
