Any s10 tranny guru's on here?

[Bamm]

Hey guys. I've got a '95 2.2 5 speed S10 and I want to swap in an automatic. I know that the "official direct swap" would have to be a '95 only automatic from behind another 2.2 (they are year specific), but what I am hearing from other tranny guys locally here is that the 2.2, 2.5 and the 2.8 all have the same bell housing bolt pattern and that if I get the right year model 700R4 from behind a 2.8 or whatever (supposedly from '87 to 92 because of the speedo hookups) that I can just buy the flex plate and swap it right in with an aftermarket shifter. Can anyone here verify these facts for me? Thanks guys, ............Jerry
