Volvo MS Bangs into Gear

I have a md7a tied to a ms reverse gear. Im haveing a problem when shifting, fwd to neutral, or rev. I cannot go from rev to neutral without going to fed and playing with the shifter. Same thing from fwd to neutral, cant do it with out hitting reverse. I have tried adjustign the shfiter cable, No chnage, also tried manipulating the shift linkage at the revrse gear. I had recived a sugestion about checking the shims under the shifter but havent been able to find any documents on the procedure. Any body been there?

Sounds like you might have a lot of cable stretch. Check the points where the cable is anchored and if there's any big loops in the cable. Watch it while someone shifts up and down to see how much the cable moves around. Might be time for a new cable. I had a similar problem with a VP outdrive and ended up replacing the shift/throttle control & cable.

it moves a bit, but the actual amount of movement on the tranny end looks pretty close to the shuufter end. I need to measure it. I did try shifting the linkage at the trans with out the shifter or cable and had simlar results. IT almost feels like there no detent for neutral.

It seems not the MS but rather the teleflex or whatever levers you use:

- disconnect the cables, move ms into neutral, shift forward / reverse by hand,

this is how you will now if the transmission is OK.

Undo the levers, clean and grease and work them without the cables - do they shift smooth?

Re-fit the levers (with the cables attached to the MS in their half-thread pos when the ms is in neutral. Now reconnect the cables at the levers.

If all is fine, no free play, etc. Then you are home.

With the shift cable unhooked from the tranmission the shift lever moves freely and smoothly. When I move the linkage on the transmission with no cable attached, it also moves freely seems to skip over neutral with only the slightest feeling of a detent.
I have tired changing the nunber of shims and really see no diffrence between a lot of shimsand none.
