I have a 1994 Accord LX 2.2 AT that I just bought. Upon driving it home, the D4 light started flashing, speedo and odometer stopped working. No shifting issues noticed. Also, windshield wipers have run without the switch being turned on and don't stop until car is turned off. That only happened twice, though, so isn't all the time. It's been at a tranny shop where they pulled codes on the TCU. He told me it's showing bad shift solenoid A & B, temp control, barametric pressure, both vehicle speed sensor and countershaft speed sensor. Because of all the codes, he's thinking it's not really a tranny problem and more likely electrical, which he can't fix. All fuses test out OK. Maybe a short or a relay somewhere??

Any insight would be helpful! Thank you!

 

Click the link in my signature for the service manual. Hope it will help in diagnosing some of your issues. I just bought a 1997 LX 2.2 to tinker with. Can't beat a Honda.
