My car is due for the transmission oil change and I understand the sump pan has to be changed because the filter is built into the pan. When I ordered one I was prompted to buy a service kit for £77 in addition to the £220 for the pan. I queried what was in the kit as it lists replacement bolts, a gasket & the filter ?? If the filter is built into the pan why is it also in the service kit & why do the bolts securing the pan need replacing. Has anyone else come up against this? I'd appreciate any guidance, happy to buy what's necessary but seems strange that my indie dealer has not listed this service kit as a requirement if I get them to do it. Am I being unreasonably suspicious here [/b]
