Were these transmissions, particularly the ones like the '82 model Supras had, come in any other Toyota vehicle? The reason I ask, I was wondering if there was a possibility that there might be a speedo gear for this transmission to work with a 4:30 rear gear. I would prefer to use the 4:30 gear for my personal application instead of the 4:10 that the automatic car came with, but plan to keep using the stock auto transmission. if one of these speedo gears exists and can be bought, please let me know! Thanks in advance!
