Frequently asked questions

What does the 1st/2nd synchromesh do in the LT77 gearbox?

The 1st/2nd synchromesh assembly matches the speed of the gear and mainshaft during a shift so 1st and 2nd engage smoothly without crunching. It's mounted on the mainshaft of the LT77 5-speed manual gearbox and works with the baulk rings and selector hub in the 1st/2nd gear train.

What are the symptoms of a worn 1st/2nd synchromesh?

A worn 1st/2nd synchromesh usually shows as a crunch or graunch when shifting into 1st or 2nd, especially when cold or shifting quickly. Baulking or refusing to engage cleanly points the same way. It's typically renewed during a gearbox rebuild once the synchro cones wear.

Which gearbox does this synchromesh fit?

This synchromesh is specific to the LT77 5-speed manual gearbox, fitted to the Land Rover Defender (1987-2006) and Range Rover Classic. It's the 1st/2nd assembly on the mainshaft. Confirm you have the LT77 rather than the later R380, as the internals differ between the two boxes.

Is replacing the synchromesh a specialist job?

Replacing the 1st/2nd synchromesh is typically a specialist workshop job. It sits inside the LT77 gearbox on the mainshaft, so the box must come out and be dismantled to reach it. It's usually done as part of a full gearbox rebuild rather than on its own.
