So...I've been searching this for months. I have an 87 4runner 22re with an a340h tranny and a 92 v6 with an a340h tranny. Can i put the a340h from the 92 into the 87? I have seen 1 write up from a guy who says he's done it and multiple write ups saying "I don't think so" or "prolly not". In the one write up it says to use certain parts from certain vehicles...here's the write-up: http://www.pirate4x4.com/forum/showthread.php?t=872238.
My local gurus have mixed opinions so any info would be amazing!!! Thanks in advance!
