727 TRANS ID

Anyone know Mopar performance trans numbers I have a 727 and trying to figure out if it’s a over the counter Mopar performance trans number is 3878001. M4977 8775. It was behind a 67 Hemi , had some kind of Blue fluid in it ,

Fluid is probably B&M trick shift.

can you post a picture of the drivers side pan rail stamped numbers?

Which is type F with blue dye.

3878001 is a race BB 727 offered through the old Direct Connection, and, yes the blue fluid is Trick Shift or the old Chevron type F.
