Back to the puking shifter dilemma.
It's 5 a.m. and I just finished putting the car on stands and checking the oil level via the fill port. Checked for level, subframe was at 0* no oil weeping from fill port.
The shifter's shift rod mounts in the front position directly over the gear (aka oil slinger)
Here is the underside of the Hurst (L) and White Lightning (R)
So the transmission vent does vent based on my hillbilly pressure test, yet when I parked the car after the first test drive at took this picture 2-4 minutes after it was parked you can see the air bubble next to the shift rod pivot ball, watching it live the bubbles developed very slowly, like 2 in 5-10 seconds, so not a lot of pressure but there is pressure.
The Tremec vent line has a venting aluminum cap, I don't know if it's calibrated to control pressure. I do know with compressed air pressure applied to the case my guage peaked at about 2.5 psi.
Is the vent line getting oil slung into it an negating it's function?
Is the cap too restrictive?
Does the shifter need a baffle to protect it from oil sling?
Do these shifter designs need a seal?
