Converting 904 transmission to 2.74 low gear set

no..not a lock up.Just using the 1st and 2nd gears from a lock-up and installing in a regular 904.This also takes the planetary a 5 band assembly. Using this set with a 2.94 rear is like a regular trans with 3.30 rear.Using it with a 3.23 isn like a 3.6 rear through the 1st 2 gears
i know guys that have done this and don't notice the shift from 2nd to drive difference.
