Have a 96, 4.0 ohv, 114000 miles on it. Transmission flares when
shifting from 2nd to 3rd under light load. This does not happen all the
time, but enough to have me worried. Seems to happen only when trans is
at operating temp, never when cold. Have read up on this problem, some
say a bad gasket on the valve body or loose valve body bolts will cause
this. I have a B&M Shift-Plus electronic shift kit that is supposed to
tighten up the shift. Would it help to install it? I don't hot rod, just
want max life out of the truck.
Thanks,
Jack

Jack,

I have a 95 with same motor/trans. with 121k. What do you mean by
"flare". Mine shifts less crisply than before. I have changed the
trans fuild 3 times (55k, 80k, and 105k) as I ocasionally tow. I feel
that my torque conv lockout tends to unlock alot at around 65mph
briefly raising the ending 500rpm. This isn't a shift from OD. If
search under "intermediate band" or "A4LD" you will find alot of info
from this group.

Flare is a slight increase in rpm's when shifting, sort of like slipping
the clutch. A sluggish shift. I put in the B&M shift plus, and it
tightened the shifts right up, not too tight in position 2, seems just
right. It has 3 positions, 1 is off-unit is not working normal shifts, 2
tightrens it up a little, but not real hard shifts and 3 a lot harder
shifts. 2 seems like it's shifting like it should for me.
