jgrow Posted January 6, 2014 Report Posted January 6, 2014 Just getting into dirt drags. What weight and oil type would you recommend for a 421 cub with overide and lock up? Thanks. Quote

04_blu_shee Posted January 6, 2014 Report Posted January 6, 2014 ATF Type F everyone has their brand and type Quote
trickedcarbine Posted January 7, 2014 Report Posted January 7, 2014 Any performance synthetic ATF is ok. You will find one you like for every 15 you don't like though. So once you get one that works keep using it as different oils add another variable in clutch tuning. Quote
