[Supras] 1978 Toyota Supra GT

[Eric Boeck]

Hey,

Quick question?  Does it go into first without pumping the clutch when cold?
(Without doing reverse at the start?).  You know that reverse doesn't have a
synchro, so the gears have to mesh pretty close on their own.  By lifting
the clutch, you're spinning the input shaft to the transmission, which
changes the alignment of the gears each time.  When they finally line up,
they mesh.

My 91T has the probem at times; won't go into reverse for 4 or 5 times ...
lift the clutch, spin the gears, try again, roll the car a bit so the
"output" gears move too, repeat if necessary :)

HTH's.

Eric
91T

I own a Supra and this is my first post. People say first Supra GT was 1979,
but my pinkslip says 1978. There are no others like it known in the
Portland, Oregon area.

Engine is 20R connected to a five speed transmission. Very fast off the line
with good top end torque. There are no known modifications from factory
specifications.

Runs good, but having a peculiar problem shifting. At start up have to pump
clutch several times to mesh into reverse gear. After that shifting 1 thru 5
is smooth with no detectable slippage of clutch. Shut the engine down for
two hours or so and have to pump the clutch several times again.

Master and slave cylinders are new, and fluid is up. Why does the clutch
keep losing pressure? Any ideas?

Thanks all. Does anyone else own one of these originals?
