I re-positioned the Tremec shifter to the forward position... so I removed the shifter.
Now I can see how the aftermarket shifters that don't have any seals would leak oil. In the forward position the shifter is directly above the gear and would have a direct spray of oil. I'm suprised they would have designed and sold a shifter with no seal
Here is a shot of the Tremec shifter from underneath. This shifter has a nice designed oil seal.
I went with the forward position so the shifter would fit through the console.
