Transaxle Identification
The 42LE transaxle identification code is a series of digits printed on a bar-code label that is fixed to the transaxle case as shown in Fig 1.
For example, the identification code K 821 1125 1316 can be broken down as follows:
- K = Kokomo Transmission Plant
- 821 = Last three digits of the transaxle part number
- 1125 = Build date
- 1316 = Build sequence number
Depending on date of manufacture, some transaxles will utilize a new identification label located in the same location as shown in Fig 1. This label can be broken down as follows in Fig 2:
