Spider69 16 Report post Posted August 20, 2013 Hi, I have a mach 1 69, but I don't know which kind of gearbox is installed. In fact initially this car was sold with a manual gearbox but one of the previous owner changed for an automatic gearbox. On the documents I have got with the car I can see information about FMX, C4 and C6!!! How can I be sure which kind of gearbox is installed? Thanks for your help.

RPM 1,190 Report post Posted August 21, 2013 A pic, engine, tranny numbers would help. A C6 is one piece aluminum, C4 is three piece alum, and FMX is three piece with alum bell housing and tail and cast iron center section. Bob Quote Share this post Link to post Share on other sites
