New Muncie 4 Speeds


Update on new Muncies transmissions as of January 1st 2025.

Paul Cangialosi has been involved in the manual transmission parts and rebuilding business since 1981. His BOOK on building and modifying manual transmissions is an Amazon best seller. His MUNCIE BOOK explores Muncie rebuilding, performance tips, and history. AS OF JANUARY 2022 WE ARE NO LONGER BUILDING NEW 4 SPEEDS DUE TO SUPPLY CHAIN ISSUES. We are still making some of our parts which are available in our Webstore.Feel free to contact us with any questions.

The new Muncie style 4 speed even in base form is a huge improvement over factory units. Each unit starts with a completely new gearset and all internals blueprinted by us. The internals are installed in the Supercase, iron midplate and heavy duty tail. The unit is buttoned up with a new side cover assembly and forks. The side cover assembly has shifter shafts that ride on roller bearings and in some models bushings. This improves shift feel. Every component is new, there is no core charge.

You can obtain a new transmission as a standard replacement unit with a 10 spline input and 27 spline output in M20, M21, and M22 ratios. You can have the same ratios in the 26 spline input and 32 spline output or a mix of spline combinations at no additional cost.
