Thanks for the advice. Why is it that a MAF sensor will have such a big impact on the gearbox. I have a reasonable knowledge of car ecu control systems and components but just thinking about it I can't get my head around why it should be. I understand that MAF sensors get sluggish with age. They measure air volume and mass entering the engine. If sluggish you can get an incorrect reading and this a weak or rich fuel mixture. This will though be picked up by the O2 sensors and the fuel trims altered to bring back to spec.
I'm sure you are right with what you say as I know engine management systems and components do all kinds of less obvious stuff. If you could help me understand I would much appreciate it, just for my future knowledge.
Thanks
