I can’t be sure that a bad ground is causing the problem, but here are some diagrams to show where to look for grounds if you need it. It looks like it’s under 31/7, and the second attachment shows it’s near the drivers side by the frame.
I see. Well considering the difference in miles, and color, I think my situation would be more likely to yield positive results. If it was a dark color, I don’t think I would want to change it. Also I believe I’m nearly on the service interval for changing it. Thanks for the input.
Also, with the whole issue of possible failure, I’d like to find someone that has had a trans fail, even if the trans fluid looked good before it was changed, if possible.
After doing some reading of people’s opinions, some say it’s the difference in fluid that causes the transmission to act different after changing:
“The fluid that has been in the transmission all this time has become dirty and gritty. This gritty fluid is actually providing needed friction for the worn internal parts of the transmission. Changing the fluid and replacing the filter would remove this friction that the internal transmission parts have become dependent on. If you have not been regularly maintaining the transmission throughout the life of the car, you might actually be doing more harm than good if you replace the transmission fluid at this point. For example, putting new clean slick transmission fluid in an older high mileage vehicle could cause the transmission to slip.”
How I see it, is if the fluid is dark, it indicates an evolving problem, and changing it makes it come out. Since mine still looks good, I don’t think I have a problem, so there shouldn’t be anything to uncover. Plus the new fluid may not be a whole lot thinner than whats in it now. Opinions or more input is appreciated.

The manual says to change it at 50K if under severe driving conditions, or 100k if under normal. So even if I change it at 110k, I hope that wouldn’t stretch it far to the point of causing possible damage. My cousin recommended a flush, but I’m not confident enough to do that. I’ve seen Grand Prix’s get a flush and fluid change at 130k and be fine, so hopefully that will be the case for me if I just do the pan fluid/filter. It’s shifting just fine right now. I heard that if there’s a problem shifting before, that increases the chances of something changing afterwards, good or bad. So I just hope my chances are good. I mean, is it even a “roll of the dice” if you do it at 50k like many manuals say?

Sorry to bump the post, but I have a related question. Although I don’t understand why the transmission would ever fail after a fluid change, I am thinking of doing a fluid change on my 2002 Pontiac Grand Prix GT. I don’t know if the risks are higher if: It has more mileage, the fluid is a darker color, or if it’s because of the amount of time in between changes. But, I bought this car used with 108,000 miles on it, and I’d like to change the fluid because I have no knowledge of past trans maintenance. I can tell you what I do know. It has 109,000 miles, upon checking the level and color, the level is in the middle of the two lines, and the color is a normal translucent pink/red color. Since the fluid is a bright red, I would like to just drop the pan and change the fluid/filter. Is it recommended, and what would the risks be, providing the details I have given?
