I have a BRF that is slipping in 1st and second. I got another tranny from a buddy that is coded "OG", I know the OG was behind a 307 motor and are not desierable. So, I swapped the governer, servo and valve body from my BRF to the OG. Will this work just to get me back on the road while I'm rebuilding the BRF and do I need to move any check balls around to go from the OG valve body to the BRF?
