2000 Tundra V8 4x4 transmission replacment | Toyota Tundra ...
A340F is the model number that Toyota provides. The major part of the transmission that includes all the internals, minus the bell housing, tail housing and maybe some connectors is the 30-40LE part number provided by Aisin. This number can be found on the side of our transmission. i believe it's a blue/silver metal tag.
