The tranny in my 60 Hawk dosen't shift right.In normal driving its OK,except
theres no kick down,gear reduction for passing.
Also,by starting out in L and switching to high thers a definite slip where
the tach jumps,but the tranny dosen't shift right away as it should.
Also if you floor it in drive the same thing occurs,a very quick shift to
high then what seems like a moments slippage.
Would a fluid change help?
Seems to me there must be some adjustments needed.

Sounds like the throttle-to-transmission linkage need adjusting (assuming
the fluid level is ok). I can never remember which way to turn it, but
moving it a few turns will definitely affect the shifting (tighter, quicker
shifts and no slipping plus you should get your kickdown back). The Shop
Manual details measuring pressure to set it correctly, but I think most
people use the "seat of the pants" system.

Second that. I'm not sure about the BW trannys but a lot of trannys
use the throttle pressure linkage to adjust shift quality as well as
shift points. A fluid change and band adjustment probably wouldn't
hurt as well. If the throttle pressure linkage is out of adjustment
you definitely won't get passing gear kickdown. I would adjust so it
upshifts at normal acceleration at about 30 MPH or so and then see if
you have passing gear, if you do then see how the shift quality is and
if it's still bad do a band adjustment.

Sounds like you need to *shorten* the linkage, FWIW. Follow the whole
setup procedure in the shop manual from the carb. back. Are you using
an Edelbrock? If you are the linkage *needs* to be in the big hole for
the adjustment to work correctly otherwise the tranny will never see
"full throttle." The hole that is about the right size is too close to
the shaft, it shortens the pedal travel. Goes without saying that you
should be using the spring loaded throttle linkage.

good luck

Shorten the length of the rod for a later upshift. Also, sounds like a
band adjustment is in order..

Sounds like the throttle pressure linkage is disconnected.
