    07 Tundra TRD 1st gen
    Hello! I have a few questions: (1) How do I know if my 07 Tundra SR5 is a 1st or 2nd Gen? and (2) My transmission overfill valve will not turn when pressure is applied.

    07’ Tundra would be a 2nd gen. If you have a 4.7L you will most likely find more out about engine related questions here in the 1st gen section.

    Definitely 2nd Gen then. You have the 5.7 and the newer body style. Best to ask any questions you have on that forum. Bievenido.
