Just bought a 88 4 runner with a auto tranny....First auto I've had..Are they worth anything? The truck runs great and shifts good but I'm thinking about converting it to 5 speed. Is there several different auto trannys and If so can you point me in the direction of figuring out what it is...I know It has 4.30 gear if that helps.
these autos are really reliable. people don't know a lot about them, so they tend to bash on them. it's the same auto as in a jeep. i think the jeep autos are call an AW4 or something like that. they come out of the same factory from all the research i've done. i had one behind a v6 in my 90 runner. it was awesome. you can install duals behind it too. both inchworm and gearslug have a conversion. then regear the axles like mentioned, mine had trouble pushing the 35 mtr's i had on it with 4.56 axle gears if that helps.
in case you want more info there is an article on 4x4wire.com were Marlin did dual cases for a guy years ago, but the adaptor from inchworm is a much more simple swap now-a-days.
good luck!
