I have an 87 GT sbc 5 spd. Am I right in thinking the trip odometer is electronic just like the odometer. My odometer works, the trip worked until yesterday. Probable a wiring issue? or is there a mechanical drive between the odometer and the trip? Looks like another "winter" project. The list so far is headliner, convert to fuel injection, enlarge gas tank, add side scoops, paint the nose, work on fuel gauge sender and the trip odometer.

Thanks, Woody

On every fiero I've owned, you have to push in the reset button, and let it out slowly for the trip odometer to work right. Don't know why, but if the zeroes aren't all lined up right when you let out on the reset button, it'll just click.

Try resetting it slowly, and see what happens. It's a Fiero Feature.

I.have also found that reseting the odometer slowly while moving helps as well. I usually do.this as i am pulling away from the gas station.

It's a common problem for the trip odometer to not work correctly. I have to do the same as what is mentioned in the previous two posts - roll forward a little bit while slowly depressing the button. If that doesn't work then I have to mash on it a few hundred times.

It's fun relying on a half-working trip odometer when your fuel gauge doesn't work

What he said works for me. If I do it sitting still it will usually get stuck.

Just got my '88 GT and it has the same problem. Is there a fix, or do we just have to live with it?

My son's 87 GT has a similar problem, you can reset the trip odometer in the usual manner, but it will sometimes slip over time and jump up to show several hundred miles. A local speedometer repair shop told me they are not repairable but I don't know if that means replacing the entire assembly or just the trip odometer part of the gauge? I will probably try to find one in a local junkyard sometime and experiment for myself. I find it hard to believe that this subject isn't covered more on Pennock's.

I think it has something to do with the way the trip odometer is connected to the regular odometer, that is mechanical I believe and works by gears from the regular odometer. I could be wrong but that would be my guess as in if you do it several times it works fine. anyone have a spare dash board they can actually look at from the back and see might be able to shed some more light on the subject. I know the old ones where mechanical and with car manufacturers wanting to save every nickel they can during assemble I can see it never have changed until they went to digital odomiters and trip odometers like they did around 2000.
