Hi Folks,
I have a '74 MGB that I recently installed an overdrive transmission ('75
according to the little blue nameplate on the overdrive unit) in.....
Mechanically, it was a bolt up slip in deal..... Now I have two problems:
1) the speedometer reads about 15-20% too slow; and 2) the overdrive doesn't
work...... I have focused mainly on the overdrive functionality so far with
no success. The solenoid valve gets power in 3rd and 4th gears and does
actuate (although I have no idea how much force to expect).... I have not
(yet) dismantled the oil pump and other then pulling the engine back out
and dismantling the overdrive I'm out of ideas (except, of course, to
dismantle the oil pump which I can do 'in car'.....
Any ideas or personal experience would be welcome at this juncture.....
