Jerico Transmissions Question
« on: March 30, 2026, 04:04:52 PM »
anyone running a Jerico Transmission.  How do they compare to a Liberty or Lenco?  Thinking about a 5 speed clutch less unit

Thanks

I ran Jerico DR4 4 speeds for over 20 years, but switched to a G Force after Jerico stopped offering replacement parts for them. As far as I know, Jerico is effectively is no longer in business.

Do you have the five speed available to you now?

If not consider a G Force 101A

If you're talking about the Liberty Equalizer, and not their TKX series, and the Lenco, there is no comparison to the Jerico. The Equalizer and Lenco can handle much more horsepower without issues (reasonably speaking, of course). There's nothing wrong with a Jerico for racing, I have a DR4-4, but parts availability would stop me from getting one now. For moderately high horsepower, I'd choose a G-Force. For maximum performance engines, I'd choose a Liberty, but that would require driveshaft tunnel cutting to make it fit. It's wide.

Not to mention that a Liberty or any other clutchless manual transmission will jump out of gear, into neutral is you lift off the gas at all. I have not ever driven a clutchless transmission, but know several people that do (or did), and even just driving around it the pits, on the return road, or to or from the staging lanes, the jumping out of gear is a pain in the butt. That requires coming to a complete stop, putting it back in gear, and hoping that you don`t need to unload the transmission again. You can try to hold enough hand pressure on the shifter to help keep it in gear, but if it does kick out, you could hurt your wrist.
