1968 manual transmission
I have a stock 4 speed manual transmission and was hoping someone could tell me which 4 or 5 speed would be the best and easiest to swap with this one. We have an inline 6 cylinder 292 motor.

Re: 1968 manual transmission
With the 6 cyl I'd go with the NV3500

Re: 1968 manual transmission
Stock vintage set up w/ 292 L6 would be SM465. M-Y '68 was first year for 465. That's the granny gear-2-3-4 four-on-the-floor, cast iron case. Ultra reliable and bombproof.

Re: 1968 manual transmission
68OrangeSunshine, yes it has a granny 1st gear, 2,3,4. We are looking for something more efficient to put in.

Chevy used them in the '80s, ending with the '87 MY in trucks and Blazers. There's an 11 page thread about the NP A833: http://www.67-72chevytrucks.com/vboa...d.php?t=670789

Re: 1968 manual transmission
Look into the AX15 5 speed trans also. Novak makes an adapter to put them behind a standard GM pattern bellhousing. I am installing the newer version of the AX15, called the AR5 in my '67 GMC with a V6. Novak's adapter works on that trans also! Sourced the trans from a 2009 Colorado 4 banger truck. The Jeep guys beat the snot out of these transmissions and have few issues!

The Jeep AX15 or the Toyota Supra Turbo R154 5 speeds.(basically the same trans) The adapter is a little pricey but it is milled, and the kit comes with a GM front bearing retainer/throwout sleeve and mounting hardware. I have the AX15 in my '34 Ford Coupe behind a Chevy 377 stroker motor. I haven't driven it much yet but it seems pretty smooth. LockDoc
