Engine/Transmission (1998.5 - 2002) 6 sp out of a 04 for a 5 sp 99

[jhoughton]

Just wanting to know if anyone has swapped a 6 sp out of a 04 to a 2 nd gen 99 with a five speed. I can get the trans and cross member. Do I need anything else out of the 04 to make this work? Want to make sure that my transfer case will bolt up to it before I spend the money for the trans. Oo.













99 Red 3500, 5sp, LT235-75R-16, Gooseneck hitch, Gauges EGT, Boost, Fuel Pressure, Rhino Liner, K&N Air Filter, E-Brake, Edge Comp, 4" SS Exhaust, Mach 1. 6 Injectors, 60,000 miles, SB Clutch soon.

As long as it's a NV5600 and not a G-56 it will bolt right up to the engine and transfer case but the driveshaft will have to be lengthened and shortened, etc

Thanks for the quick response. I will check on that.

You'll need a clutch with a 1 3/8" spline to run with the NV5600.

With my latest upgrades of injectors and the Edge comp. I have already noticed the clutch slip with the comp on level 2. So before I buy the 13" clutch upgrade to the 5 sp I am looking at putting the 6 sp and clutch all at once.

You don't need the crossmember, and FYI, the 04 crossmember doesn't work on a 99. Front driveshaft lenghtened, rear shortened, 13 inch clutch, and the flywheel redrilled for it. Or get the flywheel and starter from the 04.
