How can I determine if the tranny is a "powerglide"?
Powerglide as I know it is an old General Motors 2 speed automatic found in the Chevrolet product line. I have rebuilt a handfull of them for friends some 27 yr ago...
That will require the more expensive filter kit.
And also what specific ATF is required for this vehicle? How many quarts?
Seeing this post is in the Hyundai Entourage forum...... there is no serviceable filter on the transmiaaion used in the Entourage... the correct fluid can be had at your local Hyundai or Kia dealer, part number 00232-19012, get 6 qt bottles
