I just bought a 96 spyder convertible and the auto tranny seems to work fine except it doesn't shift into 4th gear or overdrive maybe I'm not sure . If I don't push the OD button on the shift handle it shifts smoothly thru 1,2,3 but if i push in the OD button when it goes to shift it's like there is no next gear, the engine revs like I pushed a clutch in .Nothing! is there some kind of shift module or electronic shift switch on this engine? The guy I bought it from says they replaced the 5th gear and seals in the tranny but still no 5th, any ideas on why or how this is happening. I could see it if it just didn't go out of the lower gear but to shift into neutral basically is strange to me. Any help out there? thanks in advance

 

sounds like the 'end clutch' needs to be replaced

 

Shift syncros go out first. Just had to replace mine. same symptoms, plus no reverse after a while

 

I read an unauthorized Mitsu forum and several people said it was the "overdrive clutch pack " and that it was accessible to replace without removing the tranny , like its located on the outside of the case maybe, anybody heard of this? I need a repair manual specific to this car , don't like Haynes too much but if thats all there is. It really seems like it"s electronic, like a shift solenoid or something similar, all other gears are smooth as new , Rev, 1,2,3and then 4th and 5th nothing, even tho the actual gear itself was just replaced. thanks for the assistance .

 

the overdrive clutch pack is the "end clutch" like i said. My brother had the exact same problem. And yes you can replace it without removing the whole transmission since the end clutch is just that...on the end of the transmission.
