3rz manual to auto box what bolts up?

[speedstar751]

After options on what the best way to change from manual box to auto is I have a 93 I've converted to 3rz from 22r has w59 bell housing and g52 box at moment.

I can get 2wd auto box complete with bell housing torque converter etc can I use marlin crawler adapter and gear drive transfer with reduction gears?

I have a r150f box complete would the transfer case from it bolt up to a 2wd box?

Would a complete box with chain drive transfer from a diesel surf or v6 4 runner bolt up to the 3rz 2wd bell housing?

I'm in Australia if the vehicle models don't make sense sorry.

Thanks in advance

It would be best not to use a 2wd trans since this requires more cost in adapters.
The A340 auto trans has interchangeable bell housings and you should be able to bolt up a 4wd trans to that. Changing t-cases is a simple adapter for the older cases.
Mine is a 22re trans with a RZ bellhousing and a 3VZ torque converter. I have this info all in a thread here.

Ok thank you the 3vz is the v6 isn't it so if I get a complete 3vz auto set up with the torque converter and 3rz auto bell housing and flex plate i should be right to bolt it together then just have to work out wiring and ecu etc? Obviously pedal and shifter changes.

The front pump spline on my 22re trans was different than that of the 3RZ trans. The issues were two different spline counts on the trans, two different bolt patterns of the TC and I have a selection of trans so I just mixed and matched til I had all the parts that worked. If you have all the right 4wd 3RZ parts then you would have no worries as far as bolting to the motor. Then just deal with what transfer case setup you want.
