Bought the car with 109k now has 111k looked at fluid smells a little burnt and its a brownish-red. Thinking about doing a fluid change but afraid it might be too late, because of the past 100k just run the same fluid rumor. However, the tranny doesn't have any problems shifting or in overdrive. Fluid was burnt from a surging problems which turned out to be bad plugs. Anyways, you guys safe to do the fluid flush/change? I am thinking of using dex/merc synthetic with maybe lucas stop slip to thicken the fluid...in case the rumor is true.
*EDIT* Car is a 99 Buick Regal gs
