went to main dealers today to order brake switch/oil seperator and accelerator assembly, reasonable price i thought (£80) so asked about oil change on box.full service including box and engine oil change £300 including vat asked about t/convertor, they cant do that and have never heard a way of doing it!.rang sheffields best auto box specialist(their words)they laughed at me as if i was a fool and said only way was to take the box out and turn it upside down! now call me old fashioned but i cannot allow anyone to work on my car if they dont do their homework. if they call themselves specialists i expect them to be just that ,and that includes main dealers.
