I don't think they'd put the TCU in unless it was going to be an auto but as far as I'm aware the only factory auto 4.2 td were 94 that's with Nissan Aust on the compliance plate .
Have seen one that had been converted to a manual so it's not impossible but the compliance plate will tell you country it was sent to and transmission it had .
