Determining the installed transmission type from VIN alone has traditionally been hit-or-miss. Not knowing the transmissions installed in the vehicles in your inventory can present a number of challenges. Unfortunately, the existing VIN standards do not require OEMs to encode transmission information directly in the VIN.

This article explores four common questions about VIN decoding transmission data, and provides suggested solutions for significantly increasing the match rate of decoded transmissions in your inventory or data feed.
