1999 Legacy Outback with 137,00 miles. When put into forward gears, will hesitate (Slip) for a few seconds b/4 engaging. Will go into reverse just fine. This has been an ongoing prob. I did a fluid drain and new filter awhile ago and it helped a little. Now it has gotten worse, will not go into forward for a longer duration. I cannot find the band adjusting screw. I'm going to try to drain and refill with Castrol high mileage. Another prob. has been the speedometer has worked sometimes, but now seems to not work at all. Any other suggestions?
