Re: Transmission fluid change or not?
Bert it the nail right on the head... The transmission has seals, valves, and little bitty pins and ball bearings all over the place that depend on hydraulic pressure to work efficiently. These parts break down and weard down with temperature and hydraulic fluid breakdown. When the fluid breaks down to a certain point (Brown or worse, smelling so aweful it makes you cringe), then your parts are as well, so when you put nice clean thick fluid back in, these parts cant take it. Especially FWD vehicles and 4WD vehicles.So, Pink to red, change it, Brown to black, rebuild it. Believe it or not, its only a couple hundred bucks to drop the valve body and replace these parts before they total your transmission. So if its brown or worse, Save up about 500 or so, and tell them its been to long since its been changed and you need the valve body rebuilt and new bearings and seals. Then you will be good to go for quite some time.
