It's a 200 lb transmission that is heavy duty but shifts pretty well, compared to older 4-speed truck transmissions.
Much of the information is online.

www.nv4500transmission.comThe NV4500 has two major problems, lube and 5th gear.
The lube is a problem because it takes a gallon or more and the stuff is expensive.
The fifth gear is a problem because of the original design. Again read up on it online. There is at least one real fix for the problem.
For a heavy 3/4 ton truck the 4500 is the choice for a 5-speed. The A833OD isn't in the same ballpark with respect to strength.
