Frequently asked questions

What is the STC3378 gear kit for?
STC3378 is a 5th speed layshaft gear kit for the R380 5-speed manual gearbox, fitted to Defender and Range Rover P38 models. It replaces the 5th gear components on the layshaft during a gearbox rebuild.
What does the kit include?
STC3378 supplies the 5th speed layshaft gear components for an R380 gearbox rebuild. Check the parts breakdown with us to confirm it covers everything needed for your specific rebuild, since gearbox kits vary in scope.
Why does the 5th gear on an R380 gearbox wear out?
5th gear on the R380 typically wears from high-mileage use or a history of clutch slip loading the gear teeth unevenly, leading to whining noise or gear jump under load. It's a well-known weak point on the R380 box.
Does this fit both Defender and Range Rover P38?
Yes, STC3378 fits the R380 5-speed manual gearbox used in both Defender (1987-2006) and Range Rover P38 (1994-2001) models.
