I looked in my car, and seen that switch. It should be relatively easy to get at, but if I tinker with it, and something is wrong, will i need parts on hand, or is it just possible adjustment? I'm hoping to look at this tomorrow, and I want to be prepared for whatever. My hope is that I can use this car for a decent sized trip to take my kid to a different city for summer camp. I don't want to be on the side of the road. This is sort of a time sensitive trip. The car runs fine except sometimes from a stand still it struggles.
From what I understand this is because that switch isn't gearing it properly for the situation? )Please correct me if I'm wrong. Would whoever answers take a car such as this on a 600km in one day trip?
Whatever help I can get I will take. My options are becoming limited.

Today is my last day to do anything about this. Please, any information that will help. I'm scared I will take things apart, and not have what I need to finish it. Kind of hard to run to the city for parts with a taken apart tranny .

Heh, well never mind, I just took a good close look at my car and the pictures, and this is a simple looking job. Maybe that'* why I didn't get a reply huh. Everyone laughing at me lol.
How do you remove the gear selector arm, its in my car and buried by obstructions. I cant get a close look.

OK well the whole assembly was on pretty much finger tight. I couldn't see the dot Bill was referring to, but i made sure all was OK and tightened it back down. That strange wtf style buzz when in gear is gone, and the car ran way better. Still a slight bit chuggy. When it cools off I am going to go **** with its location a little. Start in center and move whatever way shows improvement? he he.

You didn't get a reply because I was moving mulch. You'll need a bright light and remove the nut on top (15mm) to see the dot. Line er up and you should be good. If not.. new switchy.

Well just to wrap this up properly, I made the trip to drop my son off at camp. did 650kms in a 11 hour period, and short of a few hiccups here and there, mostly on bigger hills, the car did quite well.
If your car is acting stupid in OD, or chugging from a stop, I would seriously recommend checking this part for yourselves! I have been harassing my motor and fuel systems and vacuum lines and etc etc etc, for months, and it turns out to be a loosened transmission piece!
It seems the nuts had probably vibrated loose, as there was no real signs of it being recently touched. Amazing that 8th of an inch that it can move, can make such an impact on your car. It was doing it at random. Sometimes it sat right, sometimes shifting moved it off point.
Well anyways, all should be well after I get a moment to find this elusive dot!
Thanks a lot bill, I think I can finally trust this car now.
