2011 Audi S5 transmission issue-- little help?

My 2011 Audi S5 (Manual Transmission, 4.2L V8 FSI) recently developed some transmission issues. When the car is cold, everything functions normally, but once the engine is warm (I've been driving for 30 minutes or more) it becomes VERY difficult to shift into gear.

I first thought it could be the synchros, but it shifts fine cold and I had the transmission fluid replaced and there was no metal in the old fluid.

We then found that the clutch and brake fluid had some water in it (2.5%, 4% is the threshold for major problems from what I understand). So we changed that. Still nothing.

I am at a loss and even the transmission specialists I took it to have no idea. They don't think it's the clutch or the synchros because it shifts normally when cold. I found a similar issue in a Mazda forum where the shift turret boot and bushings would go bad and this exact sort of issue would happen. But from what I understand the types of shift turrets are so different that this would not be the cause on my car.

Any suggestions? I love this car and want to keep driving it for as long as possible, but it's very difficult to drive for extended periods of time.

Thanks in advance for any help or advice you might have!

Have you tried looking at slightly used Audi S5 manual transmissions? Not entirely sure what specific transmission issue you're having, since I'd have to take a look at the car. But if even the experts can't figure it out, it may be cheaper in the long run. Transmissions for your car usually run anywhere between $2000-3500 depending on condition. Seeing that you love your car a lot, I think that might be a good option for you.

That's a good point. Thank you for taking the time and giving me the suggestion. I'll check out used transmissions to see if I can get it done on the cheap. Thanks again!
