Long shot But does anyone know if the gear changes on a Auto Mx5 are ECU controlled ? Thanks Dave |

You can get an MX5 with a slush box? WHY? I suppose the US market, where "driving stick" is an art few possess, might have a use for such an abortion! I would guess that earlier cars would have mechanical control as fully ECU controlled transmissions didn't really get mainstream until the mid 2000s. Having used (and had a lot of bother with) the GM 4L30E ECU controlled trans in the Dolomega, next time i'd use something less complex, or even stick to manual transmission if a suitable mechanical control trans wasn't available!

As far as I know, the MKI & MKII Have a conventional mechanical auto box. There is a mechanical selector lever connected to the box in the normal way. There is an electrical switch on the selector arm, (Mazda call it the range switch), but all that does is the Neutral/Park starter inhibitor and also the reverse light switch. No sign of any autobox ECU. Peter |

Steve My brother wants a MGB GT but auto, auto MGs are hard to get ive seen a manual car, and i know someone who has a mazda MX5 auto, it was an import thats rusty he want rid off, The MG auto use BW35 which is a 3 speed box where this MX5 is 4 speed, thats the idea Dave |

My GM 4L30E box has a mechanical select rod that needs to be adjusted for exact positioning and also has the inhibit/reverse switch in the selector quadrant, along with a park lock deactivated by the brake light switch and switches for "sport" and "winter" modes.There is a mechanical selector lever connected to the box in the normal way.

No sign of any autobox ECU. Peter It also has a massive trans ECU (bigger than the engine ECU) but it doesn't live in the equally massive relay box under the bonnet with the engine ECU. In the original Vauxhall fitment it was hidden behind the dash on the drivers side right up under the bottom of the screen. Unless you were really looking hard, you'd never find it! I've shortened the loom considerably and mounted it behind the glove box on the Dolomega. Steve |
