I need to buy 2 AOD transmission 3-4 accumulators(some call them servos). I cannot find them anywhere. I can find the 2-3 but no-one has the 3-4. I have contacted every transmission shop that google gives you when you type in this info and they have never heard of a 3-4 accumulator. I must have them for a 1986 Mustang 302 transmission. I will not give up. I must find them for my boss--I cannot fail at this! Please help someone!! I will pay shipping charges or whatever it takes. I will upload a picture showing where this part goes in a tranny. Thank you, Kathy with a "K"
