54-56 Ultramatic Parking Gears

Posted by humanpotatohybrid On 2024/1/27 18:16:01

Recently the question came up about the styles of parking gear on the twin ultras. I figured I would take a look at mine. The parts books and counselors give:

450227 - 54GS, 55
424275 - 55 (revised)
6470248 - 56

However mine clearly says 470102 which is not even a number for anything.

My trans serial is 52491.

Anyone know if this is normal?
