LT230 Transfer Box R Type & T Type
The LT230 series Transfer Boxes were introduced in 1983 with the LT77 5 Speed Gearbox range. The first boxes were known as the LT230R. These were updated in 1984 with a change to the Intershaft and Intermediate cluster to enable stronger Taper Bearings to be used. These later boxes are known as "T" type boxes (LT230T). Although there are some common parts to the two types of boxes there are some items that are now either unavailable or expensive to obtain. The good news is that the LT230T type can be fitted as a unit in place of the original LT230R. This also makes good sense for subsequent replacement of spares.

The Serial number of the LT230 Transfer Box should be found either on the bottom side above sump by drain plug or sometimes on the end face. See the examples above.
The LT230 unit has a serial number consisting of a prefix, 6 digit number, and suffix. This serial number will determine the type of box & ratio. The suffix will determine the approx date of manufacture and gear design used. Below you will find a table showing most of the common variations.
