This Muncie M20 4-speed transmission (part number (3851325) is a high-performance, vintage part that fits Chevy, Pontiac, and Oldsmobile vehicles with rear-wheel drive. It is a manual transmission that is perfect for those looking for a performance upgrade.

This transmission looks to be in good working order and has been used previously. It is a universal fitment and can be used in various applications.

TURNS NICE AND SHIFTS THROUGH ALL GEARS. FLUID IS CLEAN. GEARS LOOK GREAT. NO CRACKS OR REPAIRS. THREADS LOOK GOOD. ALTHOUGH I HAVE NOT PERSONALLY USED THIS TRANSMISSION IT SEEMS TO BE IN GOOD WORKING ORDER.  REPLACE THE SIDE COVER GASKET BEFORE USE BECAUSE I OPENED UP FOR PICTURES AND INSPECTION. I AM SELLING AS A CORE TO REBUILD BUT THATS UP TO YOU.  Thanks #6MTRANS
