the problem I've been having is that my slightly modded 07 cobalt ls 2.2l has now blown its second transmission. i have lost my 3rd gear syncro. love the car but im starting to get tired of putting trannys in it. i was running 2.6qts of RP max atf. from what ive heard the f23s have weak syncros. was wondering if anyone has found a fix to this problem?
