Those of us that know the Tremec 3&OD transmissions of the 80s will know what to look for but there isn't a lot of information out there on them for the average person who may want one and start looking in the salvage yards. My warning has to include the two different single rail transmissions that were made for Ford by Tremec Mexico. The truck version is not the same as the car version so my advice is to get as much information about them as you can before purchase even for parts. To find the gear set a person wants requires the correct two digit alpha gear code since there are more than one ratio involved with these units. Some may be more desirable to a potential buyer than others depending on the application.

Some folks in both the model A world and the early Ford V8 world are looking for the turret shift type T170 RTS TOD transmissions and they show up less and less as time goes by. Not so many are looking for the single rail shift types but you still have to know what to look for.
