Title: auto 2nd to 3rd........... Post by caprimanuk on Oct 13th, 2007, 7:52pm Help.....just bought a scorpio ultima estate 2.3 16v automatic . the gearbox is so lovely and smooth that is appart from the change between 2nd and 3rd , if driven very very carefully its fine but keeping your foot on the throttle will cause the revs to rise another 1000rpm then go into 3rd with a thump . If your quick you can take your foot off the throttle which stops it going in with a bang . fluid is fine up to level , and is not brown . all other gears work A1 no probs . Does anyone know a cure , is this going to be expensive ? |

Title: Re: auto 2nd to 3rd........... Post by caprimanuk on Oct 13th, 2007, 8:47pm thanks for the reply , but all other gearchanges are really smooth cannot be felt really . You think that cleaning that would cure 2nd to 3rd thumping ? |

Title: Re: auto 2nd to 3rd........... Post by caprimanuk on Oct 13th, 2007, 8:55pm can you give me some examples maybe ? Just seems weird why cleaning that would cure it . Its had full ford service history and apparently theres nothing at all wrong with the box so they say . |

Title: Re: auto 2nd to 3rd........... Post by caprimanuk on Oct 13th, 2007, 9:16pm thanks will give it a clean tomorrow , I really cant understand how this would cure the one gearchange problem though when all other gears perform correctly . |

The MAF is wondrous but ( like teenage children ) slightly cranky and high maintenace, and controls many of the gearbox's functions. Give it a clean and get back to us. ::) |

Title: Re: auto 2nd to 3rd........... Post by caprimanuk on Oct 14th, 2007, 11:49am well I cleaned it . couldnt remove it from the main plastic air filter housing though . still same problem , and to be honest it wasnt really dirty . |

Title: Re: auto 2nd to 3rd........... Post by ADroste on Oct 14th, 2007, 3:33pm @ caprimanuk Are you sure that it's between 2nd and 3rd? Could it also be between 3rd and straight coupling? I'am thinking about the overdrive function. Overdrive reduces rpm by 1000 1/min. If it is this, than pressing the green OD button in the lever would have no effect. Regards Armin |

Title: Re: auto 2nd to 3rd........... Post by drawlings on Oct 14th, 2007, 4:30pm Hi Caprimanuk, I have a similiar problem on my car, the connector to MAF sensor was dirty. Cleaned it and it was ok. HTH |

Title: Re: auto 2nd to 3rd........... Post by pappa on Oct 15th, 2007, 8:13am Hi Caprimanuk. Believe it, the MAF has a great effect on these cars. I just cleaned mine (almost a brand new one!) and it smoothened my ugly gear change to "not so ugly". It's not good yet (I recently did a huge engineswap operation on my Scorps) and I'm looking for the reason for it. In your case, adjusting the break bands could help, but check the more obvious and easier things first: - MAF cleaned with a non residue electric cleaning spray - Auto Oil level checked with the engine in normal running temp - Have it scanned - DTC's may give more information Others will no doubtly give more good tips. |

Title: Re: auto 2nd to 3rd........... Post by Simmo on Oct 15th, 2007, 9:12am I would not use carb cleaner on the electrical connections as it is likely to have an adverse effect on the plastic. If you couldn't remove the MAF from the main air filter housing ( it's only two clips and then it should pull out although the 'O' ring may be sticking but a spray of WD should sort that), how did you access the elements of the Maf to clean them?. The link put up by Andrew shows them in detail. ???. |
