You bet I'm doing the same thing. I feel like I'm not using my leg strength/power at all in my jumps. I just raise the chest and "jump" which is as retarded as it gets. I know it doesn't look like that in my videos but living in my own body (weirdly enough) I can tell you that's true.
The thing is - how do you correct it? That's why I liked a lot what Rippetoe said about the low bar hip-driven squat. When I heard him say "don't drive the chest up, use your hips" for the first time, I was like "bingo, that's what I have been doing all along".
That is NOT the same thing as driving with the glutes, hes cueing a hamstring dominant move if anything there, and vectors are much different than a jump as well. You want to learn to use your GLUTES, to drive yourself UP, not drive your ass into the air leaned over.
A true "glute dominant squat" would look like a good morning. You would sit way back, and not drive UP, youd drive your hips FORWARD like a kettlebell swing.
This is similar to Lou Simmons reccomendations, however its NOT what we use the squat for as we NEED KNEE EXTENSION FOR ATHLETIC MOVEMENT AND THE SQUAT TRAINS THAT WELL.
The glutes primary role is at the end rom, when the quads are at a huge leverage disadvantage to contribute. The glutes are also put under a maximum stretch this way, and definitely get tons of stimulation.
This is why front squats hammer the glutes as hard if not harder than squats.
Now don't live under the impression that I was "manipulated" into thinking that - I know I have always "raised my chest" but it never occured to me how to put it into words.
The problem is - I have no idea how to cure it.
When I deadlift I raise the chest.
When I clean I raise the chest.
When I squat I don't though, weirdly enough. I put a lot of quad load instead (I don't really push my hips back because I'd just fall backwards)
When I KB swing I can use my hips pretty well.
When I RDL I raise the chest. I feel the same tendency to fall on the back when I RDL as in the squat (or even more really) - it's really, REALLY annoying.
Any ideas on how to fix this? Box squatting could be an answer but I don't have any boxes in the gym and using a bench that's very narrow I could easily miss it and just have a big accident happen. In fact, because of my fear of missing the bench, when I was doing "bench squats" I was even more quad dominant than in a free squat.
So as you can see, I'm a really weird kind of guy. But hey, you already knew that didn't you? 
Everything you think regarding how to fix glute driven movement is wrong man. The key to fixing this is keeping your PELVIS IN NEUTRAL. In a sl clean, your torso and hips should make a straight line, not in lordosis.
When you load this way, you have no choice other than glute driven extension. The squat is primarily a KNEE HINGE. Youre supposed to raise the fucking chest.
What Rippetoe is doing, is getting the hamstrings tight and more involved, making sure they are on stretch through a longer part of the rom. The glutes work regardless, as long as youre deep enough.
To fix it youre going to have to get strong in that movement pattern, with SLOW movements first, then progress down the speed spectrum. I would start with glute bridges prior to cleans or sl cleans/sl bridge.
This really fires up that movement pattern, and helps the glute driven extension. Once you get that down, progress to sl bound complex w glute bridge (sl).
The thing with the sl clean and sl box squat is, they tend to do this automatically, if you do them right. Ive seen lots of sprints and jumps change for the better with those exercises alone.
You have to do whatever you choose CONSISTENTLY, and RIGHT though. Post videos, when you see it, it always helps. You can get this though, its not some super elusive thing to master.
Ive taught some pretty slow minded individuals how to use their glutes in athletic movement before, its really not as hard as youre thinking it is.
