Dear 6packers:
I just finished installing a rebuilt A-type overdrive in a 1972 TR6. Some of
you previously answered questions I had on cable routing - again, thank you.
The good news is the box shifts well and the clutch works great with the
Gunst bearing. The problem I have is that the overdrive kicks in and out
just fine while the vehicle is on jacks, but while driving, under load, it
will not. Believing I put everything together right (all new seals, springs,
bearings) and adjusted things properly, I put a pressure gauge on the
operating valve tap. I get just over 300 pounds at 60 MPH. By the way, the
overdrive is an early A-type from a 1960 TR3A. It has the large, simple
accumulator. Some things I read say that 300 lbs. is too low. Has anyone had
a similar experience?
Much appreciated.
