John K, excellent picture. Thank you.

Bill, thanks for the clarification. A follow up question. If I drag race with a stock VB and shift kit, do I risk over-spinning the trans in the water box in first gear?

I got the bolt in sprag ordered and on the way. I'll be busting my hump getting the assemblies cleaned, inspected and reassembled with new parts so that they are ready to assemble monday when the sprag gets here. More to follow. Thanks guys.




With a stock Valvebody when you pull the trans down into Low it applies the rear band. The only time you risk overspinning is if the trans in in 1st and the sprag has failed , band not applied , that is when things will spin backwards thru the geartrain in the trans and potentially overspeed the drum.

Buy the super sprag , problem solved, the stock replacemtn bolt in is a complete waste of money , and you are half way to the good one.




Yep.. the production VB is a LBA valve body but like
John said.. its only applied in manual low.. if left
in drive it is not applied... and the super sprag
is worth the cost over the bolt in stock style
