Can a 97 SC300 auto trans work on a 98 SC300?

I am asking because i think the gears are faster on the 97. And maybe its an easier trans to build rather than the 98 trans, also have a better launch with the 97 trans.

According to some quick googling they are the same, the ratios are 1st:2.804 , 2nd:1.531 , 3rd:1 , 4th:0.705, Reverse: 2.393. The tt supra auto had a different first gear and reverse.

The transmission is an a340e, I searched for "a340e gear ratio". That will bring up tons of links to all kinds of informative sites.

As far as obdI vs obdII, the obdII sc400s in 98-00 are more powerful.

He's right they are different, you have to research all the harnesses and see if any pins for the electronic tranny are different etc
