99 Mustang V6 Auto transmission problem with overdrive
Hi all, long time viewer first time poster. Thanks for any help I get and for the info I have already found on here over the years.
I have a problem with my automatic transmissions overdrive. When I have the pedal down to pick up speed it will shift extremely hard into overdrive. To the point where the whole car shacks/shudders (kinda similar to driving over those speed bumps that are really small but there are 5 of them in a row) Now it wont do it when I let off the gas a tad when I know it is about to shift into overdrive. I have driven the car for many years with it doing it. I just have been watching when I is about to do it and just release the gas a bit. I have done numerous searches on here about it and the only things I could come up with are either the overdrive band, overdrive servo, or the MLP. Do any of you guys think or know it is one of those or is it something entirely else? Thanks for any help.
