I am in the process of rebuilding a "A" type overdrive transmission for my TR3A. I have read lots of posts regarding warpage of the adaptor plate particularly along the lower contact area. Obviously I am keen to ensure that I don't get an oil leak in this location & I was wondering how much distortion is too much? When I lay a streight edge along the lower mating surface I can just get a 0.003" feeler gauge to slide under in the middle area of the ruler. Would this be a problem of would there have to be a much more significant "gap" to cause a leak?
Many thanks, Neil.
