after driving for a while the automatic transmission stop working normal, like the gear start to slip but once it is cool down it start working normally.
does it sound like the computer on the transmission is bad or going bad?
I dont think is the transmission itself because of the way it work so fine.

 

How long has it been since the fluid was changed??

 

not long, last winter then now in the summer. honda atf ofcourse

 

one more thing.
do hondas have a cable linkage connected to a throttle valve in the transmission
or use a vacuum modulator?

 

I take it you are talking about how it knows when to shift. What year is the accord??

 

yup 1996

 

Now I dont own a 5th Gen. But last I checked, it's controlled by the TCM or TCU, which takes speed, RPM, and throttle signals to determine shift points.
