99 Acura Integra Auto Tranny hard shifts

Just bought a 99 Integra 2 door for my daughter. It has 159000 miles on it.
Seems in very good condition. Oil is very clean and trans fluid is clean
and full.
If you take off kinda slow the transmission has a very hard shift into
second at about 3000 rpms.
If you wind it up a little to say 4500 it shifts very smooth.
Any ideas - maybe the owner before did a computer programming to adjust
shift point. An adjustment somewhere?
Please give me some ideas to look for.

Thanks,

 

Actually - now that I think about it - not sure if it is full or not. I
don't have an owners manual and have not found a service manual for it yet.
There is a place on the dip stick that dips down to flat and then about 1/2"
below that there are about 4 xxxx then a small area below that. The level
w/ it in park and idling is at the top of the xxxx but not above it. I
assume this is right or is it supposed to be to the top of the flat area and
this marks the low area.

 

almost certainly not filed with honda atf when the tranny was last
serviced. drain & refill with genuine honda atf a couple of times - it
will then be smooth again.

 

Might get more responses in alt.autos.acura also.

 

=====================

Engine OFF when checking level, should cover XXX when warm, no higher.
The previous owner put the wrong fluid in it. Honda Z1 has special
friction modifiers that ensure long life and smoother shifts. Drain and
fill tranny three times with right stuff.

order it.
