A240E/A241E/A245E questions

[Piloter]

For my 7AGE build, the weakest point for the eventual turbo addition is going to be the A245E transmission. Now, I've been doing my research (as always) and have found a possible answer. It appears that the Mk 1 MR2s had as an automatic option the A240E or A241E boxes, the difference between these being the A241E's LSD. It also caught my eye that the gear ratios for that 241 and my 245 are absolutely identical....and as they're both A series trannies, they'll both bolt up to an A-series motor.

First question:
Was the A241E an option for the supercharged MR2? Or did the SC variant only come with a manual box?


Second question:
Would the axles be identical? Would they be transplantable?


Third question:
Should I be even pursuing this route (shift kit on a 241E, giving me speed and a LSD) , or would looking at an upgraded valve body for the 245 from Level10 be a better choice?

Any feedback would be greatly appreciated.

To answer my own question, the A241E was the automatic transmission option for the 1st-gen SC MR2, the NA Mk 2 MR2, the 90-93 Celica GT/GTS, and the 96-97 RAV4. For anybody else out there silly/dedicated enough to go this route, a 241E should be relatively cheap and also capable of handling the normal output of a bigport-based 7AGE.


That, unfortunately, still begs the question of how to control said auto tranny. Doing a manual swap would almost certainly be cheaper in the long run.
