The transmission identification tag is usually attached by the lower left extension attaching bolt or under the lower front intermediate servo cover bolt. The transmission identification code number is found on the bottom of the vehicle certification label. The transmission tag shows the model prefix and suffix, assembly part numbers, and build date code. The first line on the tag shows the transmission model prefix and suffix. A number appearing after the suffix indicates that internal parts have been changed after the initial production start up. For example, a PEE-FL model transmission that has been changed internally would read PEE-FL1. Both transmissions are basically the same, but some service parts in the PEE-FL1 transmission are slightly different than the PEE-FL transmission. Therefore, it is important that the codes on the transmission identification tag be checked when ordering parts or making inquires about the transmission.
