I swapped in a V6 lockup auto from a 1991 4 door Montero behind my 4D55T in my 1988 Montero. It went right in and took maybe 5 hours to swap.

I liked the non lockup better in town because it spooled up quicker but the lockup was better on the highway. Anyway after that experience i've decided that when it comes time to auto swap my Mighty Max i won't pass on a non lockup, i'll just take whatever i find first.
