Not to nit pick wit you Azie, but a sprag is not the same as a roller
clutch. A roller clutch is just that. The springs are not necessarilly
accordian like, in the Powerglide torque convertor (and other
applications I am sure) thay are coils. A sprag serves the same
function but is heavier duty and more expensive so they are rarely
used. I had a drawing of one but I can not find it. It is more like a
set of cams in place of the rollers, I believe there are no ramps like a
roller clutch.

It is best explained with a drawing, I think.

I don't know if there are any high performance parts being sold as such
but the usual case with automatic transmissions is that one part from
this year and another from that add up to a good transmission in the
end.

Hi guys this is my first post so if I screw something up.....oops sorry!
Well IM not sure if it helps or not but I have a haynes book for overhauling
c-3 through c-6 including aod and it says that there are three types of a
sprag which they call a one way clutch.

#1 has two end bushings, a retaining cage, 16 springs and rollers and can be
completely disassembled.

#2 has one end bushing, the retaining cage and spring assembled as a unit
and only the rollers can be disassembled.

#3 has both the end bushings, the retaining cage, springs and rollers as an
assembled unit and cannot be disassembled at all.
