That Kelvy is very, very similar to the mid-80's Frigidaire TL I had, with a different agitator design. You're getting more rollover than I did. I always felt the rollover would improve if the tub didn't index. The tranny was giving out by 1986. It used to have to drain half the water before it would start spinning. The circle-fill was very cool, but otherwise I was glad to move on.
Thanks for the video, though, roto! It's always fun to see machines at work, regardless of brand or personal preference.
