X2 on replacing the burned out bulb.

The torque converter lock up is pretty noticeable. On a flat road, drive 70 mph steadily and then slowly push the gas. The tach should jump up quickly a few hundred rpm when the converter comes out of lock due to the extra load. The opposite should happen when you ease off the gas. In either case, to me it almost feels like the trans is shifting into another gear.

Appreciate It!
 

:):)Jim/Roader,
You guys are awesome! I joined the forum expecting to get nowhere, but you've made the difference. The advice seems to be on-target.

So, I am trying to find out if the tranny has been changed out to a DX or LX model. I will try to get the D4 light working to see the code. On the latter, should I try to short-curcuit the D4 light at the instrument panel (I assume) or TCU?... I know the TCU unit is located on passenger-side floorboard, if I can get the electrical schematics for the 93 should I try to check there first? Sorry for all the questions!

I will also check to see if the torque converter is doing what Roader says it should shift on freeway @ 70 mph.

Again, thank you very much! If I lived nearby, I'd buy you guys all you can drink and/or eat! :)

Take the cluster out and put a new bulb in. It's probably a T5/74 bulb available at any auto parts store.

The quick test for the D4 bulb is to unplug the electrical connector to the TCU and ground the proper pin.

You may want to take a look at your TCU. On older Hondas, there was a sight glass with a LED that would flash the codes. They stopped having the LED by the 94 accords. Maybe the 93 still had the LED, so you can check codes that way?

Yet another thank you! I will be able to have someone look at these matters early next week so I will share all the information provided by forum members.
My sense is that you have saved me a chunk of change! (Probably not enough to fly back East to treat you all to the beer and food, though. :o)
