hi,
there is an article in the new CHP issue about installing a hurst shifter on a Muncie. I have to rebuilt my M21 this winter, i bought a complete rebuilt kit unit. there is also a strange problem with the Muncie and i recently better understood what is going wrong (i faced this 3 times) : when downshifting rapidly from 3 to 2 , it is possible to do it wrong and avoid the neutral point, engaging the second gear while the third gear is still in gear. That result in a 2 gears the same time engagement, and the transmission stays in second gear, it becomes then impossible to shift . The thing i have to do to 'repair it' is raising the car and from under it i smash with a rod agains the attach points of the shifter to the linkage and try to move the 1/2 rod or the 3/4 rod linkage again to neutral position. it is sometimes very hard to move and i really have to bang on it. with a hammer or something. when it is again on neutral, it is ok and i can shift again.

I guess the possibility of engaging a "false" second gear is a shifter problem. it happened 3 times so now i feel better what goes wrong when it happen : and it is obviously like enganging a "false" gear that 'd lay right between the 4 and the 2 . you really feel it with the shifter when driving. if you engange that "false" gear, you surely jam the tranny in second gear. It is always in second gear that it jams.
Anyway i want to fix that problem when i 'll restore the tranny. I personnely think it is a shifter problem. do you know how to fix it? CHF talks about shifter adjusting bolts but they don't explain how. Oh yes : i already have a hurst shifter installed.

Also about the article in CHP : they say the Hurst shifter nylon bushing kits reduce noises. i though of letting a friend custom built bronze bushings while restoring the tranny and shifter unit. Do you think bronze bushing isn't a good idea? about noises in the tranny .... I uses the car for fun in the summer, alos sometimes as a daily driver. but i surely don't race the car.

Please tell me a lot about it

Thanks

Marc
