After driving around town couple of days ago when I pulled away from a stop sign I heard a whir in the transmission. Didn't feel anything going on but that was a new sound. Checked the transmission fluid level, at idle, and the level was up to the full level. Didn't notice any bubbles but I will check that next time. I'd appreciate any suggestions on whether I have a problem developing with the transmission. That is the first time I have heard the whir but there have been 2 or 3 times that I heard a "clank" as I shifted from low to reverse as I backed into the garage. Pretty sure it isn't the U-joints. Thanks
