Anyway to tell if a trans is "new" or "cleaned up & rebuilt"??

A friend of mine thinks he found a new 700r4 for me, through a friend's friend. So obviously, this sounds like a bad sitcom episode... is there some special marking, like a warranty #, or etc, that woudl tell me if the trans is new, or just rebuilt and painted? My friend said the trans looked brand new... but maybe it's just got a shot of aluminum paint on it.

Thanks!

New 700R4 have not been available for almost 10 years. It has most likely been cleaned up & painted.

Since the engine produces too many heat, an old tranny has "coocked" (burned) the plastic pieces like the TCC switch connector. If you remove this connector from the case and it broke for no "flexibility" you'll know that the tranny was hot in the past = USED.


(Since the case can be cleaned completely without paint and a damaged oil pan can be changed, a used tranny can looks new!)


Other posibility: An old tranny system into a new case. Very difficult.
