Transaxle Codes and Gear Ratios
Reference table of 924/944/968 transaxle codes with complete gear ratios and final drive ratios for all known variants, including LSD options and regional differences.
Finding the Transaxle Code
The transaxle identification code is stamped on the top flange of the transaxle, near the front. The location is not easily visible — you will need an inspection mirror and a flashlight to read it. Wipe the area clean of road debris and grime first.

Note: LSD = Limited Slip Differential. M220 denotes the factory LSD option code. ROW = Rest of World (markets outside USA, Canada, and Japan). FDR = Final Drive Ratio.
Note: Aftermarket LSD upgrades are available for 944 transaxles. The Quaife ATB (Automatic Torque Biasing) differential is a popular bolt-in replacement that provides progressive torque biasing without the lock-up characteristics of a traditional clutch-type LSD.
