Ya I had 3rd gear go in two mtx75 transmissions. My suggestion is look for a used one dont bother with trying to fix it. If the gears on the output shaft are messed up its a pain to even attempt to fix. Its all press fit and you can only buy the syncro's and bearings, if you try to buy any press on gears the dealer will tell you they are "non-serviceable". You can imagin my reaction to the parts guy when I walked out to my car and brought him in an entire box with a "non-serviceable" output shaft fully disassembled in it.
