Went to install CSI trans shield and it is obstructed by the trans vent, Would you notch the shield or relocate the vent? The front pump vent is still there are 2 needed?
Thanks, John

Modifying the shield will keep it from recerting if you had any interest in that.
I have a shield on mine and I have the vent in the tail housing near the speedometer drive.

Plug your vent. Relocate it here; Doug I like that location (from the Griner instructions), and have used it successfully. I also ground a little drainage in the rib below the new vent (yellow arrows). Some cases have better or worse relief in this rib for drainage.

You shouldn't need 2 vents and you shouldn't need to relocate the vent from the front unless you are running a trans brake. We installed our vent in the top of the tail shaft housing near where it meets the case and ran a rubber hose up to a vented puke tank. This way if it pushes fluid out the vent into the tank it can drain back down into the trans I do have a brake, so your saying I should plug the front vent?

I also ground a little drainage in the rib below the new vent (yellow arrows). Some cases have better or worse relief in this rib for drainage. I plug the pump on any race unit and relocate it there. Drain is a good idea. The rear support covers most of that area to help prevent oil from blowing out, I use the plastic rearend type vent with the cap. Never had one leak or blow oil out. Cutting that shield will void the certification, and weaken it.

If the results don't match the theory, change the theory.

Plug your vent. Relocate it here; Doug Dumb question time...can the relocation drilling/tapping be done to an already built transmission like OP's (or mine), or should the case be stripped beforehand??

I don't know what shifter you have but my strap goes between the NSS and the linkage bracket. I use a turbo action cheetah shifter. Its a little bunched up in there but it works. Unfortunately due to my exhaust system that area is impossible to photograph, I can't even tell you what it looks like just what it feels like LOL.
