Update...a bit late but I thought I should update the outcome.
I decided to give them a final chance as this was the place I bought my vehicle from.
So, I brought it back the next morning and they kept it for a few hours and called me back. They said they would only have to replace the shifter knob and shaft (no kidding!

) but the part was not available anywhere in the country. They said they would have to order it and that it would take several weeks to come in.
They did actually call me back a few weeks (about six weeks later) later and said they had the replacement shifter to fix mine. I took it in first thing and they called me back about a hour and a half later saying that it was ready. The original knob/shaft was never so nice and tight. I think it must have been a little loose from the beginning as I never remembered the action of the shifting being so positive and stiff. (no suggestive jokes!)
In addition....the new knob seems to be slightly shorter that the original...maybe 1/2 to 3/4 of an inch. Makes the shifting less of a chore.
Anyway...it all ended well and they didn't give me any more crap after that first time...other than rolling eyes when my CB antenna bangs against the sheet metal door in their service garage every time I drove in. LMAO!.
