Description

If you’ve been dealing with hard shifting or grinding gears, especially when the tractor’s cold or under load, there’s a good chance your transmission’s synchronizer assembly needs attention. This critical component is specifically designed for SLE transmission-equipped tractors and helps match gear speeds for smooth, quiet shifts. When it’s worn out, every gear change becomes a wrestling match that’ll wear you out long before the workday’s done.

What You’re Getting

Precision-machined components that match gear speeds for smooth shifting without grinding
Heavy-duty construction built to handle the constant use of farm work
Direct replacement for your worn synchronizer—no modifications needed
Quality materials that resist wear from hydraulic fluid and temperature changes

Built for Real Farm Work

This synchronizer assembly fits Ford New Holland 40 Series tractors including models 5640, 6640, 7740, 7840, 8240, and 8340, along with TS Series models TS90, TS100, TS110, and TS115 equipped with SLE transmission systems. These mid to high-horsepower tractors are commonly used in precision farming operations, commercial agricultural enterprises, and custom farming services where accurate control is essential for productivity during cultivation, planting, spraying, and harvesting.

Made to Last

The SLE hydraulic system on these tractors was ahead of its time, using load sensing technology instead of constantly pumping full volume like older gear pumps. This synchronizer assembly is engineered to work with that sophisticated system, maintaining the precise tolerances your transmission needs for years of reliable service.

Good to Know

Before ordering, confirm you have an SLE transmission by looking for the electronic shift controls rather than mechanical shifters—non-SLE models use a different configuration. When installing, this is a great time to change your transmission fluid and check other wear items. Professional installation is recommended since transmission work requires specific tools and knowledge of proper assembly procedures.
