Default Sports light on + shfting problem - 10-16-2009 , 08:13 PM






Hi all,

I have a 1991 Accord. The sports light comes on when I start the car,
and remains on, though the sports switch is in the 'off' position. The
acceleration of the car from a stop is much slower, and the
transmission is not shifting at all.

Has anyone had this problem? What is possibly wrong?

Thank you,
Fijoy

It's probably in limp-home mode giving you just two gears.

As Dan has written is might be your transmission control computer. The other
possibility is a faulty sensor that is monitored by the transmission control
computer. It would be instructive to know the code that the TCU
light-emitting diode is flashing. The module itself is probably under the
carpet under your passenger's left foot. It has a small window through which
the lamp may be seen. Don't confuse it with the adjacent engine control
computer.

Do a search in the Honda newsgroups for "TCU." That will lead you to some
details of diagnosis.

Thank you all for the responses. I found this page which describes
diagnosing and fixing TCU problems: http://techauto.awardspace.com/transmission.html
