It has a cracked aux transmission case and it needs replaced. I pulled out the old one but am having a hard time identifying what kind it is so I know what would be a direct bolt in replacement box. The only markings is has is ‘NP2T’, ‘WA 1’ on the case, and ‘13442’ on the rear cast mount. If anyone could identify it that would be very helpful! Also any advice on maybe a better replacement. It has an Eaton RTO11609a in front of it now. NTC290 small cam in front of that. Thanks for the help. Not sure if this is posted in the correct place.

    You probably need to contact Cam out in California. He has a lot of older Peterbilt stuff with twin sticks.

    Seen a box like that a week ago in a wrecking yard in Kentucky, think it was a 700 ft lb though on the input shaft…..

    Thanks for the information everyone. I did see that ad before but he wasn’t sure on the model either. To my best knowledge, it is an Eaton 3H92. Now to find a replacement for a decent price. Will have to see if it makes sense to swap direct or look to other options.
