w56 trans are strong A and B are top shift C is forward shift stay away from D and E
g52 is ok but w56 is stronger. theres a 4runner in northern mi for trade or sale with 3.4l 76,000 rolled auto trans
like they said 3.0 sucks go for the lexus v8 way more power than all these little motors. dont bother with the 3.4 if your going for power doe the lexus v8! or keep the adaptors and run a 302.
I love the 22r and 22re great reliable little rebuild work only one head gasket one timing chain only 4 to re ring go to v6 and your doing double . id stay with 4cylinder unless i was planning on racing or towing a house
