Last season I had some valve body issues and corrected that with a manual Turbo action cheetah unit. Today I get to the second round start the burnout and roll out in third gear. Get the car staged and take off. Then about 50 feet out it I get a bad chatter in first gear. I shifted to second and feels fine. By that time I know the run is junk so shifted to third and back to the trailer. Got home and drove it in the garage and in first and make ugly sounds  really not looking forward to pulling the trans but... I think the sprag took a dump what do you think? Is it possible that it got hurt during the burnout?

Nice car  If it the sprag do yourself a favor and get the sprag with more rollers. I put one in 3 years ago and no problems but I am very carefull about burnouts too.
If the MODS did their job I would not be hitting the notify MOD button. LOL

A few years ago when the trans was built we put a sprag in with all the extra rollers. In the video that was 2 runs prior to  Didn't get any video of when it happend.

with drive shaft disconnected transmission in neutral try turning the end to the right then left if it turns easy in both directions i would think the sprag is shot. if you have an spare slip yoke use that to turn it or the drive shaft itself

So the trans already has either the A&A Ultimate sprag or the Coan Super sprag with 16 rollers? (vs the 12 roller Chryser).
It is likely that the valve body can be changed to low band apply, check with John Cope at CRT. He has done some in the past, but not all valve bodies can be changed.

....so are we sure the t/a valve body "corrected" the issue you were having? You just don't hear of this issue much with their manual valve body being used. I know I never had issues with mine. Too bad I don't live near you. Sold my race car, but still have the "back up" trans sitting here which I used for years prior to going full race trans. It has a TA valve body and I never had sprag issues.

Thanks for the offer. The prior valve body was a homemade manual one that a buddy had laying around let me try. Some times it it would work fine and the next pass wouldnt leave in first gear. 
After changing to the turbo action unit been fine. Its got around 30 passes on this one with no problems until now.

It's awfully hard for pieces that big to get suck through the filter
