YotaTech Forums - Automatic trans????

So, this is for you old Toyota gurus out there we're needing your help.
I have a 1982 short wheelbase 4x4 pickup that my son and I are building for him that we are putting in a 22r motor, but we need to put in an automatic transmission, but we do not want a computer controlled trans, we have been looking for a Toyota auto but all we have found are computer controlled. Could you give us some ideas of some sort of tranny/trans that we could use?
P.S. the reason we are looking for an automatic trans is that my son has Cerebral Palsy that has partially affected his right side and he has a hard time with the clutch when on hills and shifting.
