727 identification #

I have a 727 that has these number on the driver side just above the oil pan:

28920891 26373 9183

and this # stamped on the tail 24669?? #7 and 68 under that..

It also has753-4 in large numbers stamped on the housing.

The main question is: is that a good tranny to have rebuilt? I know some trannys are lock and none lock up... not sure what this one is.

Thanks in advance guys.
