I know that the NV3550 to 6speed swap is very easy and also that the NV3550 to 4500 is not hard. What I want to know is if anyone has done, or looked into the 6 speed to a NV4500 swap. I already understand the wider rpm spacing between gears and shift logic penalty of losing two usable road gears and it's a trade I'm willing to make.

 

Out of curiosity, what don't you like about the 6 speed? Are you having strength issues?

 

For right now I just like the 4500. Life changes have made it possible for me to start shopping and modding after purchase but I do plan on having strength issues.

The long story is that I'm thinkin about a blown up or oil burning 3.8 to save cash up front and go straight to the V8 swap. But if I buy a driver I like building from the axles toward the engine chasing the weak links forward and the ProRock axles are already my preference. Tons of possibilities out there and I'm doin a thousand brain storm scenarios a day lol. Buy with bad motor do V8/4500 takeout, bad tans do 4500 swap, driver do 4500 swap and V8 later or turbo/supercharger instead. Iduno my head spins but I do want to completely understand my options before beginning to weight them against each other. It won't affect my purchase but will change my plan of attack after.

Anyone know what it takes?
