Hi All,
Came across an early (1978) publication from G.M. to do with Chevy/GMC vehicles fitted with NP435 transmissions. I believe this to be related to vehicles around the 1970 era. The transmission in question apparently wasn't used by G.M all that much, but must have had some relevance to be included in the workshop manual.

Anyone know or familiar with these transmission applications? I would hazard a guess and say the reomte tower would have been used in something like campervans, small buses or maybe general cab forward delivery vans.

I was told on another forum that if there had been any kicking around, they would have well and truly been crushed for scrap by now. Seems no-one collects these things anymore. I find that hard to believe given not only the sheer size of North America/Canada, but also the population, and your well known love for your "pick-ups"

Would appreciate any help, Cheers, Dave 64 (Australia)

The US military "Gama Goat" used an SM420 transmission with a remote shifter.
Various cab over engine trucks had long bent shifters or remote linkage depending on the model.

Hy Dave 64, that transmission was used behind V6 gas 351 and diesel V6 478 in 1966 and 67, in 1967 and 68 40 through 60 series with 6 cylinder engines except diesels and 1967-72 50 through 60 series with V8 engines. The remote shift transmissions were for cabover trucks, hope that helps.

Thanks, Guys,

The SM420 mentioned is not really the one I am interested in.

However, the references that 3B gave were. Any publications or forum sites that you could recommend to pursue this a bit further?

What would be the chances of anyone having any of this NP435 stuff squirrelled away? Bloke tried to tell me on another forum that they (remote controls) are virtually impossible to source. Other than posting onto forums like this, any clues as to how I could either locate one, or at least a proper download of them? My parts book for the G.M. version is sketchy to say the least.

We have had them, the normal NP435 by the hundreds in both Australian built Dodge Ford and International, but to my limited knowledge, never had anything fitted with the remote mentioned.

Cheers, Dave 64
