Transmission: 175hrs @ $7500 = 43$/hr

I had my '08 Cup engine rebuilt at PMNA in July 2012. They replaced the intake and plenum which I thought was very strange. Wonder if this was the reason or now a problem.... phone calls to make!

WTB 997.1 gear box core

We are looking for a "back up" gear box for '08 Cup. Would prefer a "timed out" unit to rebuild vs. buying one already done.

Let me know what you got!
