A833 in GM trucks?

GM transmission code MY6. I have one in my truck. The internals are regular A833 OD. The transmission case, input shaft, input bearing retainer, output shaft, tail housing are all GM specific. It does not bolt up to a regular GM bellhousing as it has a hybrid GM/Mopar bellhousing pattern, so it needs a specific bellhousing. Somewhere along the way they made the pattern all GM apparently. The input bearing retainer is a week spot (I spent two months looking for one that wasn't broken). I would say that if you had a regular A-833 and wanted to change the gearing to an OD gear set, you could probably use the internals, but as a complete transmission swap, it won't work.
