Can anyone provide really clear instruction so a novice and adjust the shift linkage. I have a problem with it jumping out of second gear.
Pictures would help too.
thanks Rick

Rick: I am attaching a TSB article explaining how to adjust the linkage.
Unfortunately, to say this is all that is involved would be an understatement.
With the number of u-joints, spline rod ends, the support bearing and the turnbuckle, much of the adjusting is trial and error.
You may want to remove the shift plate as a starting point just to see if second gear will hold; however, make the adjustment with the shift plate attached.
The support bearing needs to be tight with no "wobble."
Check to make sure the rod splines are not slipping in the u-joints.
The turnbuckle has a left hand thread and right hand thread for adjusting the rod length.
There is a u-joint under the console just behind the gear shift lever that many times is overlooked.

In my experience....
If it will stay in gear if you keep your hand on the shifter, and it typically pops out when you are letting off the gas, then it is likely an adjustment issue.
I had a problem (mine was with 3rd gear) that was caused by the splined shaft slipping on one of the linkage U-joints.
I agree with making sure those are tight.
The adjustment is typically a two person job, but I thought I remember a thread here where one of the members made up a fixture to hold the lever centered in neutral to get the adjustments right?
I found that the trunnion bushing (Jag calls it the support bearing) works better when it is lower, as well... The trunnion bushing housing will also twist slightly when you are tightening it. Use a big crescent on the housing to make sure it's aligned to reduce drag on the shaft.
I think it might have been Marlin that had the thread on the lever-holder, because I think he was the one 'splaining the difference between a bearing and bushing to us!
Good luck

just my ramblings...
I would think that the gate to shifter over travels (X & Y) should be well known.
thus to tweak the linkage adjustment would be shove it into 2nd, adjust turnbuckle to get the expected "X", lock the turnbuckle, shove it into 3rd and if "Y" is less than expected, you have looseness that needs to be fixed.
anyone care to share their "X & Y"s
