Just interested in the reliability of the 5 speed manual gearbox (LT77) in a 1987 Range Rover. Quite rare to see them in manual guise - is this for a reason other than all the city folk prefer auto.

Only problem is that the splines on the end of the mainshaft where it meets the input gear of the transfer box get flogged out due to lack of lubrication.

You can check this by pulling off the inspection cover/PTO cover on the back of the transfer case.

There are a couple of fixes, LR brought out a splash lube plate which goes on the end of the shaft or you can fit a cross drilled transfer gear. However, a 1987 vehicle will have probably broken and been fixed by now. Anoher way to tell if there is a problem is listen and feel for a clunk in the transmission when engaging the clutch. (Although this can be other things like a worm A-frame ball joint).

The general consensus is that the 5-speed is not as robust as the previous 4 speed, especially when the horsepower and torque ante is upped with a bigger capacity engine. Most that do transplants, usually change the gearbox to either an auto or another brand altogether.
