transmission issue in reverse

I put my 2002 A4 in reverse yesterday, and as I was backing up I gave a (very) little throttle, and got a slipping feeling and sound. I tried it 3 or 4 more times and got the same thing. All forward gears are OK. I've had the car for 6 months, 30,000 miles, no mods, I don't know when the trans was last serviced.
Could this be old fluid, low fluid, or an ominous problem rearing its ugly head ??

If you are going to do this yourself, I suggest you use the procedure in the service manual.

Not a good thing, first check oil as mentioned above.
But the bad news is reverse applies the direct or third gear clutch the weak link in the A4.

It may be time for an upgrade to a RPM trans, I hear their having a sale right now.........

Are you getting kick backs from RPM, why would you recommend an upgraded transmission when the first step in troubleshooting has not even been performed yet?

Wow! I'm pretty sure he was just making a statement of fact.

To the opening poster. I agree check the fluid level then go from there.

Good luck.

Talked to my mechanic (hes not a 'Vette mech per se but he's really GOOD) and he said to let it go until it gets worse, which could be 3 months or 3 years. I'm going to have him change the oil in a week or so, and Ill also have him change the trans fluid. Should I have him change the differential fluid as well ??

This is an FYI on the fluid check. The Service Manual calls out a VERY specific trans fluid temperature range that you can check the fluid level at (IIRC it is like 87 degrees F. - 122 Degrees F.). I tested mine when it was hot (~180 degrees) and it was full. I let the fluid cool to the proper temp and I found I was 22 oz. low!!! That is why I was slipping.
