Fits Vehicles (including but not limited to)

What is the F40 gearbox?

The F40 is a 6-speed manual transaxle used across the GM Delta/Epsilon platform in Vauxhall/Opel, Chevrolet, SAAB and Cadillac models. It is a common gearbox for workshop rebuilds due to widespread use and age of the fleet.

Why do I need to check tooth count before ordering?

There is no universal part number reference for F40 gears. Tooth count and synchro pitch angle vary between production variants. Always verify the 49T tooth count and pitch angle match your stripped gearbox before ordering.

Does this kit include the 2nd gear itself?

Yes. This is a full master rebuild kit that includes the 49-tooth 2nd gear as well as all associated synchromesh, hub, circlip and hardware items.

Is this kit for the input or output shaft?

This kit covers the output shaft side 2nd gear position.

Can you help me confirm compatibility?

Due to the lack of F40 reference data, we recommend you strip and measure the gearbox or contact us with photos of the existing gear for confirmation. We are unable to confirm compatibility from a registration number alone for this gearbox.
