    Wondering which is better... what features does the NV4500 have? For some reason thought it had a built-in winch type O deal on it... but I'm sure I'm wrong.

    I'll also look for some info on the net... But any help would be great. Thanks!

    <font color=blue>Both have a low 1st gear, but the NV4500 has an overdrive. The 465 is PTO (power take off) compatable and I'm pretty sure the NV4500 is too

    Anyone know the 5th gear ratio in the NV4500?

    Looks like the 5th gear ratio is 0.73... Check out some more info at <a target="_blank" href=http://www.jbconversions.com/pages/nv4500/>JB Conversions</a>

    NV 4500 does have PTO provisions. Not that anybody runs a PTO winch these days.

    Once you have the NV4500, you won't want a SM465 again. Shifting is just great, short throws, nice &amp; easy and quiet. The 5th gear is a bonus and you drop about 700RPM's from 4th gear. Not cheap but worth it! I've run one for about 2 years now and love it.

    A good firm grip is my idea of gun control!

    Aside from the first 2 years of Chevy versions having different gears, there are a few differences between them. Don't know if it applies to Chevys, but on Dodges the '98 and ups have much shorter shifter throws (front-back and side-side) than the '97 and earlier. There have been some internal upgrades over the years, but unless you're running a seriously built motor or towing lots of weight, it probably won't matter. The only big reliability issue I'm aware of is the 5th gear nut backin off, but as far as I know its only an issue on Cummins applications.

    I am worried though that the NV4500 says its only capable of 450ftlbs of torque... my motor should come near 500ftlbs... Should I be worried?

    I am not sure where you have gotten your info, but the NV4500 is the tranny of chose for Dodge behind the V10 and Cummins Diesel. GM uses this tranny on the Big Block and Small Block equipped 1 ton trucks. I really dont think you have much to worry about.

    I may be slow, but I sure am fat!

    Not at all. Mine holds up fine to 800. Lots of guys on the TDR running more than me, the only ones with problems (other than 5th gear nut) are the ones who are really abusing them hard (sled pulls, solid-hub clutches, etc).

    Its also interesting to note that all of the 98.5+ 5 spd Cummins trucks are rated at 460 ft lbs stock.
