    Hello all! Hope everyone is doing great as always!

    For reference: I drive a 2012 4.6L 2x4 that uses the A760E 6 speed

    Was wondering if anybody knew the transferability of the A760E transmission from one model of cars to another (with a different motor). I wanted to start working on a backup transmission for a more painless (and fearing inevitable) breakdown. So far I’ve found some fairly cheap, used, Lexus IS transmissions that, as far as I can tell from the pictures, only differ in serial number.

    Wikipedia states the A760E is used in:

    2005–2007 Lexus GS 300
    2005-2013 Lexus IS 300
    2005–2013 Lexus IS 350
    2006–2013 Lexus GS 350
    2010–2019 Toyota Tundra 4.6L
    2010–2019 Toyota Sequoia 4.6L
    2009–2019 Toyota Mark X (GRX133)
    2004–2008 Toyota Crown GRS182
    (If no drive is specified, it’s 2x4 or RWD)

    Would the computers communicate? or will it just get bombarded with volts and fry it (or not enough volts at all)?

    Will it even bolt to the engine and driveshaft?

    I didn’t notice any differences in function or components listed in the A760E ATSG manual, but I could’ve overlooked.

    Would love to hear your guys’ thoughts! Thank y’all for your time!

    in theory it should it ,
    the tail housing an out put shaft would have swapped over depending on what it came out of.
    and any other little external thing that's different in a side by side comparison.
    also probably the torque converter if there's a variation in stall speed across any of the platforms

    but other than that I don't see why not unless there different generations of it in that time period.
    if the A7060E is also used in 4x4 Tundra it should be a matter of swapping out the rear housing and output shaft.

    hope this info helps in some way or another :)

    Thank ya for the perspective! I can’t find anything about differences in the A760E transmission throughout different models, so I reckon all the housings bolt up the same. The external (and really all) components of the transmission worry me, for all these different models are using different sized engines (and maybe even different differential gear ratios?). If these are possibly adjustable/replaceable (Or I have an obvious misunderstanding that’ll inevitable hit me as I research on), I’m all game lol.

    I’ll keep reading and looking and will keep it all posted on here as I learn more. Thank ya again for the insight friend!
