v5m31 would be the one to have BUT we didn't get it state side but if you choose to import one get if from a pajero with a 4m40 they came with the 4.234 first gear that tranny is a beast!! You'll also need the bellhousing from a 4d56 with the same tranny behind it.

State side v5mt1 came behind gen 1 v6's, gen 2's, and sport's the newer the better once again you'll need a 4d56 bellhousing to bolt to your 2.6 plh has/had one up for sale.
