    Has anyone looked into taking the 5-speed manual from the Tacoma and putting a 6-speed in its place? Will, it not work? I am the new owner of a 2007 Tacoma, and I go on the freeway with it quite a bit. I was curious to know if anyone has ever done this or looked into this.

    What would be the issue if there are any?

    Thanks

    I don't think it would be possible. The 5 speed was on the 4 cylinder and the 6 speed came on the V6. It would take a lot of fabrication for very little gain, if any.
    I did some searching and here are the ratios for each transmission:

    5 Speed:
    1st 3.95
    2nd 2.06
    3rd 1.44
    4th 1.00
    5th 0.81

    6 Speed:
    1st 4.17
    2nd 2.19
    3rd 1.49
    4th 1.19
    5th 1.00
    6th 0.85

    With the 6 speed your engine will rev slightly higher. I don't really see any gain from this. You would be better off looking into different gearing in your rearend.
