Transmission Repair Parts
Transmission Gears
Replacement gears for manual and automatic gearbox repair and overhaul — supply coordinated from China, with specifications and fitment confirmed per inquiry.
Where These Gears Are Used
Transmission gears transfer engine power through the gearbox, setting the speed and torque delivered to the drivetrain. In repair and overhaul work, worn, chipped, or damaged gears are replaced individually or as matched sets to restore shift quality and gearbox service life.
We coordinate gear supply for B2B buyers such as auto parts importers, gearbox rebuilders, and parts distributors. This site does not publish fitment lists — compatibility is checked against the gearbox model or part number you provide.
Gear Types & Applications

Spur Gears
Straight-cut gears used in manual transmissions and transfer cases, typical for reverse and low-speed gear sets.

Helical Gears
Angled-tooth gears for quieter, load-bearing constant-mesh gear pairs in manual and automatic gearboxes.

Shaft Gears
Gear-and-shaft integrated components such as input shafts, countershafts, and output shaft gear sets.

Specifications Confirmed Per Inquiry
Gear specifications depend on the gearbox design and the supply resource assigned to your order. The parameters below are confirmed with you before quoting — no generic data tables are published.
- Module / diametral pitch and tooth count
- Helix angle and hand (for helical gears)
- Material and heat treatment requirements
- Tooth profile and surface finish requirements
- Individual gears or matched gear sets
The items above are parameters to confirm, not published specifications.
Model & Fitment Confirmation
Where reliable application data is available from the supply side, we share it with your quotation. We do not publish OEM numbers or vehicle fitment lists on this site.
To check a gear for your application, send the gearbox model, transmission type, or the reference number of the part you are replacing, plus photos and key dimensions where available. The supply side verifies compatibility before we quote — fitment is not determined from appearance photos alone.
Quantity & Quotation
Both distributor stock orders and workshop-level quantities can be evaluated. MOQ, unit price, and lead time are confirmed per order against the gear type and quantity you need.
Submit the product name, gearbox model or part number, quantity, and destination country through the quote form — drawings or sample details can follow by email.
