Near the end it seem that second gear is make a lot noise, high whine. First and third are fine. So what could this be?

I know I have a similar symptom with that scenario, but usually it is in all gears. Seriously, I'm sure that you checked the condition and level of the oil, right? Does the noise take place constantly or does it fluctuate? If your oil level is good, I would suspect a bad bearing. If the oil has any water in it, you can count on a bad bearing. You can try to drain and refill the oil and hope that it helps.

It will give you an idea if something mechanical is failing inside the transmission. | | | | | Joined: Mar 2011 Posts: 940 'Bolter | | 'Bolter Joined: Mar 2011 Posts: 940 | Mine was loud. Pulled the plug on the trans (3OTT) and it was almost dry. Added fluid and it was virtually silent. | | |
