What Jatco Box Do I Have?

[Themauler]

Hi all,

Just wondering if anyone can shed some light one how to tell what model jatco box's I have. For the life of me I can't find any model numbers.

Also will an rb30 torque converter work in a rb25det box?

Thanks

If it is a stock car I believe you will find the number on the blue plate on the firewall (although R31 is a few years ago so I can't be sure about that).

The box's are out of the car. Ones an rb30 and the other is supposably an 2b25det box. There are tags on them but they only say jatco 45X77 or jatco 45X11 but that doesn't seem to come up anywhere.

Put a picture up

The box on the left should be a 25det and the one on the right should be a 30

[Themauler]

Sorry I image attached now. The tag is off the 25det box

[turboedsloth]

They are both RE4R01A's by the looks of it

[Themauler]

Is there a way to know for sure? Is it marked on the box anywhere?

[turboedsloth]

They will be on the cars id plates. You can go off the sumps aswell.

Thanks, I'll have to go by the sumps as I don't have the cars they came out of. You don't happen to know if the torque converters are interchangeable by any chance? I'm about to order a 3000rpm hi stall one and want to make sure it's the right one

They would be the same. pull them out and check the snouts, heights, flex plate bolt pcd etc

Thanks, got it sorted now
