Just wondering where I can get another gear for my speedo? The Fiero store doesn't sell them. My friends '86 is not the same. Any ideas please and thanks, Andy |

The dealer should sell or be able to get them. This is going to be a more common problem now that our cars are getting older. Having a good knowledge of trannys and what gears went with what tires, it is sometimes possible to get a gear to make an aftermarket wheel and tire swap read more correctly on the speedometer as well. ------------- Capt Fiero 88 Fiero GT 5spd V6 Eight Fifty Seven GT V8 5spd. |

| The plastic gear I'm looking for was connected to the little shaft on the sensor. Does anyone know if any years are compatable? |

No one can answer your question without a few more details.
What Year do you have What Trans Do you have If a 5spd is it an Isuzu or a Getrag What colour is your stock gear ------------- Capt Fiero 88 Fiero GT 5spd V6 Eight Fifty Seven GT V8 5spd. |

| '85, getrag 2.5 5 speed, bought the car without gear, so don't know color. My friends is bright red, it doesn't fit on mine. |

There's something else wrong then - as they'll all "fit" - the speedo just won't read correctly! Each color is just a different tooth count. |

Hi, I'm still looking for the plastic gear for my speedo. I don't know the color it was. It's a 2.5L 5 speed tranny. 1985 notchback. Thanks Andrew |

Unless someone has gone to a great deal of work, all 4cly 5spd cars used an Isuzu trans. Just go to your local dealer and ask for a new one for your car, or hit up a wreckers and find a 4cly trans and pull one. ------------- Capt Fiero 88 Fiero GT 5spd V6 Eight Fifty Seven GT V8 5spd. |

I checked the wreckers and called GM, it's discontinued. I even called across Alberta to all the wreckers. No fieros in stock. Any more ideas? Thanks |

It doesn't NEED to come from a Fiero - All the trannies from almost all GM products are going to use the same sender - just the tooth count is different. If you check your RPO sheet there will be various codes - one of which will be what the original sender and tranny was. The trannies are: MD9 3-speed automatic transmission (THM125C) MG2 Transmission, manual, 5-speed ( MG3 Transmission, manual, 5-speed ( MM4 Transmission, manual, 4-speed, provisions (84-86) MM5 Transmission, manual, 5-speed, provisions (85-88) MT2 5-speed manual transmission (Isuzu) 3.35 ratio MV9 3 speed automatic transmission (THM200C) MX1 3 speed automatic transmission MY7 4-speed manual transmission (Isuzu) MY8 4-speed manual transmission ( M17 4-speed manual transmission ( M19 4-speed manual transmission ( The senders are: D4N Gear, speedometer driven (N) 29 teeth 10041031 (red) D4O Gear, speedometer driven (O) 30 teeth 10041032 (purple) D4P Gear, speedometer driven (P) 30 teeth 25519845 (blue) D4Q Gear, speedometer driven (Q) 31 teeth 25519846 (white) |
