So here recently my transmission has started to act funny... city driving at normal throttle it shifts out absolutely perfect! But for some reason only wen i give it WOT (to the floor) it wants too not shift an is delayed bad an starts screamin from second then it launches into third?? Any of yall trans guys feel free to chime in. the fluid is not dis colored. will changing fluid/filter help any of this? or bad TP sensor? scanned an no power train codes either TIA guys
