Ford guys

I have a C-6 trans with three fittings on the passenger side. Which of the two are for the cooler lines. One is at the front of the trans and another is in the middle just above the tranny pan and another parallel to the front one just in front of the tail shaft housing.

 

I think the one by the tail shaft is the speedo drive.

 

^ yup thats right
IIRC

 

The speedo drive is on the drivers side. The trans we took out only had a place for two cooler lines on the passenger side but this one came with three plugs in it and no fittings so I'm not sure which two to use.

 

Jr. - kinda like SBF pulleys, too many options!

This link pretty much shows everything about a C-6 transmission.
Hope it helps.

 

I believe the one down by the pan is a pressure port for running tests on the trans and should already be plugged
