At G Force Transmission, we provide full-service inspection, repair, and rebuild solutions for the industry’s most trusted racing transmissions and quick-change rear ends. Whether you run circle track, drag racing, road racing, or off-road competition, our service department delivers factory-level precision, OEM parts, and unmatched technical expertise.

G-Force Racing Transmission Service

We offer complete service, rebuilding, and performance refresh packages for the full lineup of G-Force transmissions:

• GSR (G-Force Street / Race)

Full teardown, cleaning, component inspection, gear evaluation, shim setup, bearing replacement, and reassembly to factory spec. Ideal for racers demanding maximum durability from their Pro-level dog box.

• G101A (4-Speed Racing Transmission)

Comprehensive service for the legendary G101A, including dog ring inspection, gear tooth evaluation, center support checks, shift rail and fork alignment, and optional ratio changes.
(Note: G101A units do not use an internal oil pump; our service includes external lubrication path checks.)

• GF2000 & GF2400

Professional refresh and performance optimization for the high-load GF2000 and GF2400 platforms. Includes gear cluster inspection, bearing upgrades, internal clearancing checks, and dyno simulation where applicable.

• GF4A (4-Speed Racing Transmission)

Complete GF4A factory service—including the internal pump system, dual-bearing center support, mid-plate sealing surfaces, and all shift mechanism components. Ideal for maintaining reliability under extreme racing conditions.

TEX Racing Transmission Service

G-Force is the official source for TEX Racing service and parts—because we acquired the TEX Racing brand years ago and continue supporting all legacy products.

• T101A

Full OEM-spec service, dog ring inspection, gear ratio changes, bearing replacement, and case evaluation.

• SR-1

Professional rebuilds and maintenance using authentic TEX Racing components and G-Force tooling. Each SR-1 receives detailed fitment checks, blueprinting, and lubrication path verification.
