ford 3.03 question

[1967mercury]

how would i go about changine the fluid in my 3.03 tranny, and what fluid do i fill it up with???

[fordman]

there should be a drain plug on the side of it down low. 80/90 weight is the easiest to find and fill it up with.

[FORDification]

The factory shop manual says to drain the lubricant on the 3.03, you remove the lower extension housing-to-transmission bolt.

To refill it, you'll need a hand pump with a tube (available for $12 at O'Reilly's) , which you insert into the fill hole on the side of the case.





(Transmission shown isn't a 3.03, but you get the idea.)
