By far the most common issue with the 6HP26 is faulty solenoids.

I did as above earlier in the year. I sent my valve body to a firm in Luton (can't recall the name at the moment), they tested it and found some faults which they repaired. I reassembled with new seals, sump and oil and then reflashed the software using my IID tool. Almost 12 months later and the problem I had (similar sounding to yours) hasn't reappeared. |

not the same car but I had my TD6 box reconned with a new torque converter 4 years ago and paid just shy of £2000 at an auto box specialist with 2 year/24,000 mile warranty (whichever came first) |

I've had exactly the same issue on a similar car and gearbox, luckily I became one of Phil's guinea pigs. All of the problems were down to one solenoid. Yes, just one of them!

Thanks for the response guys! RRphil, if I was to remove the mechatronic unit, send it off for testing is there a cheap way of re flashing the gearbox software now I've reset the adaptations like a fool? cheers |

If you have an IID tool you can do it with that, for a small extra fee. |

Thanks to the contributors. This has solved my problems by IID TCM flush and replaced solenoid valves. |

This fixed my problem couple of years ago. Now it is coming back intermittently. Reset fault and will go back to normal for a month or two. Now it also reads bank 1 rich sometimes. Can the bank 1 rich code and the transmission fault related? |
