Hi guys wondering if any of you could steer me in the right direction, on my way home on m6 today car was running great no problems then as i came off at my junction i lost all drive , it was as if the clutch was slipping but mines an auto , anyway managed to crwl it most of wayhome but at a juntion lost all drive exept for reverse but it dosnt feel right, feels like its engaging gear when you put in druve bu just revs....any ideas please

Has it dropped the auto fluid?

no mate doesnt seem to be any leaks ? was fine then entered roundabout and just reved then came back but then went all together, does occasinally engage a gear but not for long
