Please note that, due to core availability, we may not be able to offer the LT77 50A variant Defender gearboxes. It may be that you will need to send your own unit to us for reconditioning or as an alternative you could consider upgrading to the direct fit R380 replacement. If you email us we can advise if supplying from our stock is currently possible or not.

This section covers the LT77 and the later LT77S as used between approx 1982 to 1994.

There are many different types of LT77 used in the Landrover range, the first ones were used in about 1983, these were the suffix D (last digit of the serial number) and were the weakest type. The LT77 was developed through to the suffix H LT77S and was last used in 1994, please have a look at the related “technical information” section for further information on this progression.
