RE: 4000 CSQ transmission trouble
Before digging in too deep, check to make sure that the shift linkage is
correctly attached to the shift rod coming out of the tranny. Unlike
the FWD trannies, the qs rely on rotation to engage the gears. There is
a bolt on the end of the shift linkage that is used like a monster set
screw in an indentation on the tranny's gear selector shaft ... if this
thing starts backing out the gears will start to get loose and then
eventually go away. BTDT a couple times on the urq (after the tranny
was replaced). Now that I've cleaned and Loctited the linkage and bolt
it's worked fine for many years ...
There are also a couple of plastic parts in the linkage that can
deteriorate over the years ... which can cause shifting problems.
Another linkage problem is where the ball (in the ball and socket joint
at the selector shaft end of the linkage) works itself loose ...
HTH!

BTW, you can see the selector shaft fairly easily by jacking up the
front left corner, removing the left front wheel and looking through the
hole where the steering linkage passes.
