Hey all
Last weekend I was co-driving a very nice Nissan SER at Sebring built by Russel Mcmullen that we won the last enduro with at Daytona,
Russel ran it in practice and I set out to qualify the car was running great I was on my third lap and just radio'd in that I was going to turn it up a notch when I came out of corner was shifting nice and ez no speed shifting put it in fourth let out the clutch and it was like I was in neutral?????

No loud bang no grinding no metal on the drain plug???? Even with it on jack stands it feels like it goes into gear but doesn't?
All other gears work fine?
I'm a Saturn driver so this tranny is a little different for me any Ideas?
Thanks
O.B.
