I am trying to find my transmission fluid fill port, but I can't find the cap shown in how-to videos. Has anyone seen a clamped rubber cap (as seen in the pictures) covering their fill port? Would that be my fill port? Thank you!
Sorry about the blurry pictures

 

If that is the only "cap" looking thing on the top of the transmission, yes.
It is actually a vent cover not meant to seal.

 

No that rubber cap is on the thermostat housing, your fill port for the transmission will be to the right a bit and forward.


There’s the thermostat housing up on the left, see the threaded hole that’s the full port

The cap in place



It’s hiding straight down from the tip of your finger
