Not being expert on transmissions I can only go by the statements of the guy who rebuilt mine and the QA part of me agrees with this. He said the type of fluid used in a rebuild of older design auto transmissions should be the type that works with the type of material used in the clutches and or bands.
His feeling was that the newer materials better suited to newer fluids. Also said he felt it was better to use the same brand if fluid needs to be added. All of his comments made sense to me and if need to add fluid. Most old car owners carry a few extras with them just in case such as engine, trans, oil brake even brake fluid. I try and keep the same brand just being a little more cautious.
