LT77 / LT77S / R380 Gearbox Serial No. Location
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, then a six digit numerical, followed by Suffix Letter. Suffix A to H is an LT77 Transmission, Suffix J onwards is an R380 Transmission. 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.
