Transmission is fixed
After tearing third gear to little bits at the Edmonton Indy, we pulled the transmission out of the car to assess the damage. The transmission is a T5 with a G-Force straight cut dog-engaged gearset and the damage was bad. Third gear was toast on both the mainshaft and countershaft. As well, the countershaft bearings had oblonged the case. I had to buy new gears, new bearings and seals and a new case. It is all back together now and ready to go back in the car.
