This approval gives you full access to the site, to pictures, and to post, among other things.

'62 215 V8 with Dual Path: How bad is Dual Path?

Discussion in 'The "Juice Box"' started by halfmoontrail, Sep 15, 2009.

    Newbie on here, I have a '65 GS vert project, a '72 GS350 project; and I just picked up a '62 215 4-bbl and attached Dual Path automatic transmission.

    Based on its small size and weight, and because it is still attached to the 215; I'd like to use the dual path in my Triumph TR7 V8 conversion.

    How bad are they, and can they be built for better results?

    Thanks,

    Steve

    Well, first it is a unique little transmission. Very simple in theory, and a little ahead of it's time. The dual path statement is exactly what it is. Lo gear (in L or Dr) has a planetary reduction and uses the torque converter, whereas when in Dr, the upshift to high gear is direct drive, literally. The direct drive clutch connects the tailshaft to the torque converter, but there is a lockup clutch in the converter that is used in high gear. So when in Dr and in high gear it is simply a mechanical connection from engine to driveshaft.

    Now the pros and cons. Pros: small in size and weight and is compatible with the 215. Cons: Two speeds, parts are very rare and might have to be fabricated.

    Conclusion, you may want to look into a more modern Rover transmission that is compatible with the 215 bell pattern.

    That was a great explanation that goes far beyond what I understood about this transmission. Having rebuilt one, it's a very simple transmission, even to someone who doesn't normally tackle such a task.

    I would say a nice litle trans for a cruiser, not for high-perf. No-one ever said an automatic 215 skylark was impressive, however, almost everyone I have known who has had one with a manual said it was an impressive little car!

    Adapting a 200-4R would be a great match for this engine, IMHO. They are kind-of heavy though if weight is a real consideration.
