2002 Volkswagen Passat Repair Question
My Passat only upshifts and downshift at high speeds/RPMs when in Auto Mode
Yeah, flush it. Brown is bad.
I took the car to VW for a flush and they do not do flushes. They said flushed have a tendancy to be followed by more problems or failure altogether. I did find out that the transmission fluid was actually fine. The tech was kind enough to bring me to the back and compare my fluid with fluid from a brand new sealed bottle. The fluid that VW makes to put into these trannys is brown brand new. I described the problem to him and he believes that it is a solenoid in the valve body that is getting weak. He explained that it could be worn out to the point where it doesn't respond to the electronic pulses sent for regular shifting but that the pulses for tip mode are longer so it still responds to them. Made sense to me, reminded me of having to adjust pulses on an aftermarket keyless entry system to trigger factory locks. He said replacing it is a job that anyone who know his way around a car could do but I am unable to find such solenoid. Would you have any insight about this solenoid or where i could find it? Thanks!

No. I wouldn't not off the top of my head, and I'm unable to access our online reference material at the moment,
However, the valve body is easily reached by draining the trans and then pulling the pan. But he is correct. A worn solenoid can cause what you're experiencing.
If the fluid smells like something that's been overcooked, it has.
Hi, would there be any way to find out what the solenoid is that I would need? I know you were unable to look it up last time but I just wanted to ask. Also, I can't find the flippin donate more to this question button. How do I do that?

I just looked through our reference materials for about an hour and couldn't find any mention of the solenoid. It's an electronically controlled that is usually located under (above) the valve body in the transmissions I've worked on. It might be somewhere near where the input speed sensor is.
I'll let the admin know you're looking for a "donate again" button. Thank you.
We appreciate you considering us for another donation. We should have a donate again button installed soon.
