TRANS-04, Transaxle - General Information, Codes, and Gear Ratios


Acrobat Printable Version

General Information

If you want to know more about your transaxle, the first thing you need to do is determine which transaxle you have. If you can not determine from the option code sticker on your car, or you believe the transaxle has been changed, then you'll have to get the code directly off of the transaxle.

This is extremely difficult to do on a 944 transaxle since the code is stamped on top flange near the front of the transaxle. To be able to read the code, you'll need an inspection mirror and a flashlight. You may also need a rag to wipe the area clear of debris to be able to read the code. The drawing below is an example showing the location of the codes and how to translate the code.

After you determine the code for your transaxle, you can use the table below to look up specific information about your transaxle. More transaxle information (924s and 968s) will be added as it becomes available.
