This has to be the dumbest post yet....

I can't find the dipstick to check the transmission fluid! I found the oil and power steering dipsticks but for the life of me I can't find one for the transmission. Surely there is one, and if by chance there isn't one, how do you check it?

(and I didn't mean to call anyone Shirley)

1972 convertible
Straight 6

 

Passenger side at the rear of the engine, it should be sticking up from the trans.

 

If its a stick it might not have one a auto will be on the firewall like said.
