The code they gave me is on the invoice, i'll check later, but it did state on the invoice that it was to do with the soleniod it the gearbox.
I have no interest in changing any ECU's, done that on a previous car and its a pain, all i want to do is find them to make sure there isn't a loose connnection again and get charged £144 for the pleasure when taking it to Lexus for them to do that again.
The £500+ is what they want to change the soleniod plus labour, and if it is just a loose connection i dont wanna get mugged off.
I'll give it a go on manual and maybe check the oil, cheers.
