Winter transmission builds
A friend of mine runs a brand x car with an air shifter and has an onboard compressor in the car , I have seen several cars with them . I also saw recently that Biondo Race Products now offers an onboard compressor setup. This would eliminate the having to worry about full CO2 bottles. I considered an air or electric setup for my Cheetah shifter but after research I found that I would have to change shifters and / or the valve body in the trans . Just an FYI : my 904 has been in the car for 7 years with no problems running 11.50s at 115. I have a really good trans guy I had him build me a complete identical 904 as a spare several years ago .. I haven't needed it !
