Mendeola Transmission



Originally known as the Mendeola S4/S5 and revamped by Weddle Industries in 2013, Weddle S4/S5 sequential-shifting transaxles feature bigger gears, larger bearings, and a full size reverse gear. Recent upgrades include: improved casting procedures for stronger cases and housings, an improved shift mechanism, improved oil flow design and an upgraded mainshaft bearing retainer. The Mendeola MD transaxle pioneered the most widely-used aftermarket transaxle and opened the door for higher horsepower and long travel cars and comes in a variety of suitable options PBS Mendeola.
