The following data was pull out of a previous thread on the subject, kudos to Lynnrockonsmile :
1987 911 G50s have an 8 digit code stamped in the bottom, for example 'G50/0073H'_'12/00050'
* G50/00 = G50 trans
* 7 = trans for 6 cylinder
* 3 = 5-speed Rest of World; 4= 5-speed USA/Japan/M298)
* H = 1987 model
* 00050 = serial number
A 1988-89 trans has a 12 digit code, such as 'G5000 1 J 00903'
* G5000 = trans type (see below)
* 1 = normal differential (0= no diff, 2= ZF ltd. slip diff)
* J = 1988 model (K= 1989)
* 00903 = serial number
Transmission types:
* G50/00 = 911 Carrera, R.o.W.
* G50/01 = 911 Carrera, USA/CND/J/AUS
* G50/02 = 911 Switzerland (very short gear ratios)
* G50/50 = 911 Turbo world wide, 1989 only
* G50/52 = later Porsche turbo boxes ZF ltd. Slip

G50/01...1st-3.500...2nd-2.059...3rd-1.409...4th-1.125...5th-0.889 after 1988, 5th gear was 0.892

G50/50...1st-3.154...2nd-1.789...3rd-1.269...4th-0.967...5th-0.756 Beefier internals, differential cover, and case
G50/52...ratios are identical to G50/50, however, doesn't have the beefed up internals, differential cover, and case
The structure of G50, etc., 12 digit serial numbers goes as follows:
G5001, G5002, G5003, etc. = transaxle type
The next digit indicates variations in that particular transaxle, eg., 0 = no differential, 1 = "normal" differential, 2 = ZF limited slip
The letter code designates the model year. H = 1987, J = 1988, K = 1989, L = 1990, M = 1991. The model year "letter" was
omitted, as of 1992.
The last four digits designate the serial number of the specific gearbox in question.
Some Porsche tranaxles had 8 digit serial numbers.
The first digit (7) indicated that the transaxle was built for a 6 cylinder car.
The second digit indicated location (4 - USA, Japan----3 - rest of world)
The third digit indicated differential type - 0 = no differential, 1 = "normal" differential, 2 = limited slip differential (40/60)
The letter designates the model year.
The final four digits designate the serial number of the specific gearbox.
The following is a list of which cars the different transaxles were installed in, where, when, lube oil capacity.
G50-00 - 911 series---worldwide---since 1987 model - 3.4 liters SAE 75W90

G50-10 - 911 Carrera RS---worldwide---since 1992 model---factory installed limited slip (40/60) - 3.6 liters 75W90
G50-50 - 911 Turbo---worldwide---1989 model---3.7 liters 75W90---beefed up internals, differential cover, case, some factory LSDs
G50-52 - 911 Carrera---worldwide---since 1990 model - 3.6 liters 75W90 - same ratios as G50-50 - some factory LSDs

930 through 88 was a 4 spd.
930 for '89 was the 5spd G50/50 as seen in chart.
