First lap of heat, motor suddenly revved up....
Pulled in and shut car off figured tranny was shot
today i pulled the tranny completely apart and clutches all looked good, planetary unit still looked good... pump hasn't been taken apart but when we got the tranny out of the car i put the coupler shaft over the pump ears and i could spin the p ump easily.... in gear... is the pump bad?

rules do not allow...
i'm going to a three speed mini clutch setup but would like to replace whats bad in this thing and keep the ball valve, tranny, and coupler for a backup in case i would roast a clutch or break a tranny

Do the clutches or steels look like they've got heat checking? If not then they either completely disengaged (i.e. acted like in neutral) or were completely engaged when the tranny was in drive (i.e. stripped internal splines on the coupler or coupler not engaged properly.).

Does the tranny work in low/reverse after it slips?

Have you checked and cleaned the valvebody? Checked / replaced the filter?
Is the fluid clean or is it burnt smelling?

after i pulled off the track, i could still move in high, but all the tranny did was slip... im now wondering if i was low on fluid...it had been leaking out of the front of the direct drive coupler shaft a little in the shop then stopped one day and i checked fluid level and it appeared to be good... the clutches have no signs of burning or slipping or heat checking, still lots of life left on the clutches...

since the clutches weren't heat checked they weren't slipping - I'd suspect the drive coupler or input shaft splines. Also - are you sure that the coupler is being held into the front pump? The snap-ring is installed and the pump drive isn't backing off and slipping?

100 percent sure the coupler was in there good
input shaft doesn't look twisted or missing splines

you stated the pump didn't get taken apart yet.... but the spline on the input shaft are fine..... did you pull the input shaft out??? I suspect that is what broke.

You can pull the input shaft out without taking any thing apart....wiggle-wiggle-pull is the normal method of removing the input shaft. if the shaft is broke the early stock inputs with 6 cylinder motors with 4:11 gears had a stronger input shaft, these are better than the after market ones.... Harder to order, but less expensive and better in the long run.

3 things to do that will fix it #1 get a mini clutch and hardware #2 go to a junkyard get a saginaw 3 speed (MAX 50 bucks) #3 put the F U C K E R in and go racing

I don't feel there is a need to use that sort of language on this form, I don't feel it should be used anywhere........ But it does get used at OTHER web-sites, that's why I don't visit those sites...

I'm sure OUR web master will edit or delete your post for you, then maybe even give you a black flag.

You would be better served to just edit you post your self.........

I have run glides for quite a while and recently have been experincing problems with low gear and /or reverse going out. My transmission man tells me it is from Low gear starts and quit doing em. Without low gear starts it really takes away any advantage in using a Glide, Anybody else have this problem and a solution?

We were running them on asphault and kept burnning up reverse, a different older trans guy showed a friend where to drill the reverse drum to dump some pressure and we never lost another.

If you cannot run a bert or something, your best thing to do would be to get a clutch, hydraulic throwout bearing, and 3 speed and use it.

Had this happen to me and found the dogs sheared on the front pump. Now we carry a new front pump and slam hammer for spare.

We just won a feature and found when we went to unload the car at home that it was hard to push. Took it apart and found a fiber disk on the rear clutch had broken and wedged the shafts apart making it too tight. Nothing else wrong.
