I've got the same kit in my FMX. Is your's a full manual shift? When you say it slips, do you mean it's slipping out ouf drive into neutral? Or that the tranny is slipping? If slipping into neutral re-check the linkage. If your not shifting properly, how old was the tranny when you put the kit in? Did you rebuild the whole thing? The he\ard shifts could be taking their toll on the old clutch pack. New torque conv? At first mine was not shifting into 3rd properly until I realized the new convertor was not filled all the way. The fluid in the pan was going into the conv, leaving none in the pan to shift. Go figure. There is only 1 kit for an FMX tranny so it's not like you could have ordered the wrong one. And, since it shifted right in the first place it was installed correctly.
