How much power can a built NV4500 handle?

Registered. The NV4500 will not hold up to steady towing even if you limit it’s input to less than 300HP. If you limit application of power to everything but 4th it should hold up pretty well. Every other gear is on the countershaft, and the countershaft is the weak link of the transmission.

How do you convert 2wd NV4500 to 4wd?

To convert it to a 4wd just swap in a 4wd mainshaft and add the transfercase adapter in place of the 2wd tailhousing. If you don’t want to spend the money for a fully splined mainshaft you can put in a used stock mainshaft that had been replaced in favor of the fully splined variety.

The NV5600 is the workhorse trans that has tighter ratios (ending with the same final drive) than the NV4500. The gap between 3rd and 4th in my 4500 is considerable, so towing lots of weight uphill takes forethought on what gear you wanna be in/what point you need to shift, but nothing crazy.

Will a NV4500 bolt to a NP205?

The output shaft on the NV4500 is the same size/spline as the NP205 I used. I also used the ‘coupling’ from the NP205 to join them together, and as far as the cases go, it is a direct bolt-together.
