quickly and informative as possible....
tranny was leaking badly but shifted perfectly
pulled tranny to replace seals and gaskets
found clutch / band material in pan
rebuilt tranny and install B&M transpak stage 3 shift kit (with vaccum modulator still installed and connected)
flushed out lines and torque converter
added type F fluid as recommended
Now in drive trans seems to shift very soon from first to 2nd and possibly a bit soon to 3rd.
Manually downshifting into 2nd works
Manually downshifting into 1st doesn't
starting off in 1st (manually) trans automatically shifts to 2nd
Also in any forward gear there is no engine braking seems to go into nuetral unless to accelerate
checked cable linkage
checked kickdown adjustment
vaccum modulator is new and so is rubber hose
in drive shifts are firm but too soon especially considering shift kit so not as firm as I would expect
BTW this is my first tranny rebuilb and my 3rd shift kit installation. ! was a th400 and 1 was a th375 never had any problems with either one.
