I want to change the tranny filter and fluid on my truck because i hear some whining when the motor reaches full operating temperture and because my Low 1 gear will go forward but doesnt hold me back when i let off on the gas. so im guess the pump is starving a little. so what brand filter should i buy? can i buy the $10 filter at autozone or at advance auto? and can i use the Walmart brand tranny fluid? and should i put Lucas tranny fix in there as an added bonus? thanks
