Frequently asked questions

What is the FTC1791 5th gear for the LT77 gearbox?
The FTC1791 is the mainshaft-mounted 5th (overdrive) gear for the LT77 5-speed manual gearbox. Located at the rear of the transmission in the 5th-gear extension housing, it transmits drive at an overdrive ratio to lower engine speed during motorway cruising. This item is the Suffix G specification.
Which Land Rovers use the FTC1791 LT77 5th gear?
The FTC1791 LT77 5th gear fits the Land Rover Defender, Discovery 1, and Range Rover Classic equipped with the LT77 5-speed gearbox. The Discovery 1 application typically starts from VIN FA393361. Confirm your gearbox is the LT77 and check the suffix before ordering.
What are the signs a 5th gear needs replacing on an LT77?
An LT77 5th gear typically needs replacing when its teeth are chipped, pitted, or worn, often showing as whine or the box jumping out of 5th under load. Damage usually follows a worn 5th synchro or bearing failure, so inspect the synchro assembly and bearings at the same time.
Why does the suffix matter when ordering an LT77 5th gear?
The suffix matters because gear specifications can vary across LT77 production, and 5th gear must match its paired layshaft gear. This FTC1791 is the Suffix G specification. Mixing suffixes can cause incorrect ratios or poor engagement, so verify your gearbox suffix before fitting.
