They're light and relatively inexpensive and they eliminate one shift. Most of the racers I have talked to relate that they will work well in a car up to about 2800 lbs. If the car weighs more than that, it would probably go faster/quicker with more gears to lower the ratios of each gear.

Stock first gear ratio on a 'glide is 1.76, so when combined with a 4.11 rear gear for instance, the final drive ratio in first gear is 7.23:1. Using the same rear gear with a TH350 trans, having a 2.52 first gear, the final drive in first gear would be 10.35:1, so you can see how this would benefit a heavier car to have a lower first gear as well as another gear before you reach 1:1 in the top gear.

To use the advantage of a glide, you should have a relatively light car and a converter that will work with the glide.

Light, strong, and it does the trick. Many drag cars only need the two ratios for the amount of time they spend on the track. All part of driveline ratio tuning and getting the best match for the car.

1. not really for road vehicles... note they introduced 3 speed autos when the highway system really got established.

2. They're light as said before, and another thing is with fewer parts (only 2 speeds) they are less fail prone.

3. Everything else has been covered really well.

In stock form not that strong but with a few up grades can take a lot of hp. Less moving parts so less hp loss thru trans.

Some of the high horsepower pro-mod guys use a glide to tame the launch, so they don't blow the tires off. I have a friend with a 3500# sbc powered "65 El Camino that lunched three TH-350s and switched to a glide and picked up .3 and 2mph, in the 1/4. I went from 9.24 to 8.942, in a 2600# car, changing from a TH-350 to a glide.
