904 Trani

That makes sense. I checked my frictions and they all are the same thickness +- .005. I emailed the guys at Oregon Transmission where I got the rebuild kit to be sure if this is the case. I'm a little concerned about the 7 1/4 rear end too. I'm hoping the surelock will save it. Trying to keep things as stock as possible. The manual is from the Automatic Transmission Service Group. It shows for a 225CID 4 frict + 4 steels front and 4 frictions + 3 steels in the rear.
