BW 271 adaptation

[Defecater]

Is there a way to easy/quick way to change the input on a 271F so it can be used on pre-superduty transmissions?

Not sure about the answer to your question, but it's not a Borg Warner case it's a New Process. So it's an Np271. The also go by Nv271 since New process is or was new venture.

Not trying to nit pick, just figured that might help your Google search
