Vent hole ?? Muncie trans 65 FI

[Jerry G.]

I have a 65 FI car with the original trans. It appears to have a vent hole in the side cover(707). It's on the rear of the side cover and goes from inside(main case) to atmosphere. It's about1/8 inch in diameter. Is this supposed to be left open to atmosphere? Why doesn't it leak or spit out tranny lub?

I'm not aware of any vent hole that was originally used on the side cover of any Muncie transmission.

I Think the hole you are referring to is supposed to have a solid pin in it to align the side cover to the case before tightening the bolts.

I believe the transmission vent is a small hole in the driveshaft yoke, but the differentials have a vertical vent with a loose fitting metal cap that's suppose to keep windage from expelling oil.

There might be a vent hole on the underside of the front bearing retainer. It is on the surface where the throwout bearing rides right at the base. (or am I all wet on this one?)

There should not be a vent on the side cover as far as I know.

Re: Vent hole ?? Alignment Pin??

I could see this being an alignment pin hole. can anyone confirm that there is an alignment pin on the side cover of a 707 side cover?

The hole that you refer to is the oil drain-back hole, but it might also serve as a vent. I don't think that the transmission requires a vent since the space between the main shaft and the front bearing retainer provides plenty of ventilation through the front bearing which is a non-sealed ball bearing.

All Muncie sidecovers have provisions for an alignment pin.
