what do most of the Ally's run on a hot day pushing 75mph or so? Mine was around 200 and some oil (filled too much) out the vent. The past owner had about 2 quarts too much in it. What fluid should I run in it? It had Amsoil but the dealer said it calls for Dextron III. Thanks for any help. Please email me with fluid suggestions asap, changing tomorrow. ([email protected])
