The Transaxle Identification Number (TIN) is stamped on a boss that is located on the left upper transaxle housing.
In addition to the TIN, each transaxle carries an assembly part number. On manual transaxles, the assembly part number is located on a metal tag at the front of the transaxle. On automatic transaxles, the assembly part number is located just above the oil pan at the rear of the assembly.
