Nv3500

I can say the NV4500 shifts so much smoother and faster it's ridiculous. It's easily as strong as the SM 465 too...

IME the 4500 shifts fairly easily and the 465 shifts like a garbage truck. I am impressed by how easily the 4500 shifts.

The 465 is significantly stronger than the NV4500, the OD really opened up a weak spot, particularly on the Dodge models.

FWIW, my tow rig has an NV4500 and the buggy still has the original SM465.

They only came in 4.3L and 5.0L (305) equipped 1/2 tons. The 305 / 5 speed combo is very uncommon around here, the largest majority of 5 speed 1/2 tons I've seen are 4.3L equipped.

Are you trying to be funny?? 'Cause, uhh....I don't know where in the hell you've been keeping your head planted, but there are PLENTY of 350/5spd 2wd and 4wd trucks out there, pre '98 - moreso than V-6 models. I have one. Buddy has one.

There's no difference in the trannies from behind 4.3's and 5.7's. They don't have the low first gear like the NV4500, and don't have the PTO output, but not a bad tranny, IMO, for DD'ing, mild towing, and light wheeling.

Run that tranny behind your SBC in that '60, 77crewcab....it'll be fine.

So should I be worried about raising the hp/tq levels a little? I will probably hit about 350tq. But on the other hand I drive like a little old man.

On a side note, anyone know how the nv3500 compares in size to a T5? Just thinking that if this wont work for my truck maybe I could use it in my 63 Nova. I know a T5 will fit the Nova so just wondering how they compare in size.

I wouldn't be worry about it.....but, like I said, don't enter any truck pulls with it!

Maybe things are different in the states, but I have never ONCE seen a 350 infront of a NV3500 stock. Trust me, I shopped for one for literally months when I was looking to buy a new truck. Everywhere I looked I found either 4.3L trucks or less commonly, 5.0L trucks.

I also recall seeing online in a number of places that GM did not put the NV3500 infront of a 350 stock, why would they put an engine in that generates more torque than a transmission is rated for?
 
Gotta keep in mind that you only use as much torque as you require. So with perfect traction and your front bumper against a concrete wall, you'd want to avoid doing a clutch dump :doah:

Otherwise, with a first gear of 3.49 and rear diff of 3.42, you'd need to hit 2400RPM with a stock 5.7 TBI against a ROLLING resistance of 3580.74 pounds. I don't know the math to figure the dead weight required to get a rolling resistance of that much, but I do know it's a whole lot more than you should ever tow with a half ton or even a 3/4 ton.

Long as you're not into high RPM clutch dumps, you should be just fine;)

Quite possibly, but it's always been my understanding that, at least between US and Canada, whatever is available here is available up there....but even I know that isn't alway true. I understand you may not have come across pre-'98 5.7 5 spd's up there, but, believe me, I drive one everyday, and they're the most common setup for fullsizes with the manuals (meaning 5.7's other other engines).
 
Man, thats interesting. I'd never have settled for a 4.3L if I could have found a 5.7L / 5 speed 1/2 ton truck...

Good to know!
 
Thanks guys, looks like the 60 will be getting the 3500 after all. The price, after a little negotiation was dropped to $125 for everything. So as I understand I should be fine with about 350 ft lbs driven lightly and towing about 5-6K trailer every once in a while.
 
Anyone know what the tow rating was with a 5.7/NV3500 combo with 3.42 gears in a short bed regular cab. Also how much did the reg cab short beds weigh in 94. Thanks.
 
My 88 short bed C1500 pick-up was rated to tow 6000 lbs with a reviever hitch, 4000 using the bumper hitch alone. My 88 had the 5.7 tbi, 5 speed, 3.42's. The truck itself weighed in at 3750 lbs.

I'd say the tranny itself is as strong as the SM 465, but the overdrive design isn't the best. My NV4500 has the damper between fifth gear and the nut which goes a long way to preventing the problem (of the nut backing off). There was no sign of fretting on my mainshaft at all.

The dodge version has the nut right up against fifth gear...with a heavy load behind the truck, fifth gear tends to try and rotate on the mainshaft a little during the transition between on the gas and off. This works at the fifth gear nut until it loosens which turns the tranny into an NV4500 4 speed in a hurry.

To be honest I'd like to see how the SM 465 would have faired behind so many bombed CTD's and the brutally heavy loads they hauled for so many million miles...

Lost reverse in my 88 5 speed

I have an 88 with a 5.7 tbi with an HM290 transmission (the NV3500's older and more complicated brother) and i just lost reverse. I cant manage to get the lever into reverse at all. I understand these trannys are a biatch to work on (with the 4-rail arrangement) so i am going to upgrade to the nv3500. I assume they are interchangable, but i was hoping someone could confirm.
