I have a '92 Honda Accord EX. Just recently the D4 light started flashing. I've been told it was a speed sensor but the speedometer still works. I've also been told the tranny is going out. Any ideas on what is happening? Thanks.

 

In the common DIY thread on top of the gen tech help forum, there is a link to get check engine codes and transmission codes. Get the codes and post them on here.
