727 transmission

The trans in the pic is a big block 727B behind a 413 or 440 from a class A motor home (the big ones). They have a parking brake on the trans output. The case is the same, and the internals should be the same as any hemi trans... The bigger drum, 4 pinion planetaries, the deep forward clutch basket, etc. There is no internal difference between the two cases (the 727A small block unit and the 727B big block HD truck) but the tailshafts and mainshafts are totally different but can be replaced together. So you can take the small block mainshaft and tailshaft and have them installed on the HD truck 727B so you end up with a damn near indestructable big block unit.
