Henry,

Sorry for the late reply but please see my post of last Thursday =
regarding overdrive springs. I=E2=80=99ve seen the issue you describe =
when the problem doesn=E2=80=99t go away after checking the hydraulics =
or electrical. If a =E2=80=9Clong=E2=80=9D spring is where one of the =
short ones should be, it will coil bind and prevent the clutch from =
moving far enough to contact the brake ring fully. It only takes one =
spring in the wrong place to hold back the clutch sufficiently to =
prevent full contact with the brake ring. It may hold intermittently =
but will slip under load, or acceleration. Be sure to check your =
springs for compressed length since they may be the same length =
otherwise and it=E2=80=99s hard to tell a =E2=80=9Cshort=E2=80=9D one =
from a =E2=80=9Clong=E2=80=9D one.

My current overdrive rebuild went so well with me replacing a variety of =
linings and washers that were shot or just not installed by the previous =
rebuilder. I thought all the pressure producing bits looked good so =
mostly left them alone. I did the pressure test when I got it all back =
together and it was close to where it was supposed to be. I drove the =
car once and it seemed to work, drove it again and it dropped into =
overdrive whenever I lifted off the gas and dropped out again when power =
was re applied. This is pretty much what the thing was doing when I =
started the project and I'm sure was the reason for my slower than they =
should have been lap times at the Cup! =20
=20
Any suggestions on what to do next?=20

I have to chime in on issues with the A type overdrive. Thankfully I =
have NO more A types to overhaul since they are a P.I.T.A. to do.=20
The hardest part, as stated, is lining up the 2 splines that will allow =
the mainshaft to nest into the Planetary Gearset and Overrunning Clutch. =
You basically need at least yourself and a helper to put it together. I =
probably did 10-12 of these 2 or more years ago. First time we did one =
we split the adapter plate pulling the O/D on to the transmission. =
Unfortunately it was welded back together and the repair was a weak =
spot. If you force the O/D onto the trans when pulling it back together =
with the 2 nuts on the O/D studs it will break or bend the plate.
=20
The fasteners (6) that hold the plate to the back of the transmission =
are drilled for safety wire. I used stainless safety wire on those after =
torquing. Make sure you repeat the way the wire is routed through the =
bolt heads. I had a couple transmissions leak because I didn't follow =
the routing properly. I mistakenly routed some of the wire near the =
base of the plate fouling the gasket which resulted in an embarrassing 3 =
comebacks on one transmission due to leaks.
Took awhile to figure it out, dumb mistake.
