You should find the Gearbox Serial Number Stamped on a machined flat near the Drain Plug area, please see the picture below.
The Number Consists Of :
• A Prefix e.g. 56A
• A six digit numerical

You can also tell an LT77 Gearbox from R380 Gearbox by the position of the Reverse Gear on the Gearstick:
• If Reverse is next to 1st gear you have an LT77 gearbox (or possibly LT85, see LT85 section).
• If Reverse is below 5th you have an R380 transmission.
