Just talked to Chuck @ FLT (who was NOT my original builder) and he thinks its the intermediate sprag as well. I may be ordering an FLT level 5 4L80E today. I need to see what the warranty status is through my original builder. There goes my tax refund, and then some

How built was the trans and how many hobbit foot miles?

I think it was just upgraded clutches, but I'm not 100% sure. It was supposed to be good to 900rwhp or so.

2 years and about 38,000 miles on it. Only 1000 of those were hobbit foot miles though.

I couldn't blow it up on 15 psi with the old kit, and I broke it on 8psi with the new one

Well I just talked to my original builder....he said he'd tear down my tranny and rebuild it for $400 plus the cost of parts. He's going to soften the 1-2 shift also. With a replacement sprag costing less than $100 I'd only be out about $600 including shipping. As much as I'd like to give FLT my business, I really can't afford the extra $2800 right now. Looks like I'll be pulling the trans this weekend and shipping it off.

I guess on hard 1-2 shifts the intermediate sprag has a tendency to "roll over"...not sure what that means. Anyway, I guess there's a heavy duty sprag available but it costs something like $650

$600 is not too bad. The sprag clutch has a bunch of elliptical rollers that engage in one direction and freewheel in the other. Sounds like yours gripped so hard that it flopped over center.
