Default Transmission Flush

I need to change my transmission fluid and I have 120,000 miles on it. The fluid thats in there now is brown, Should I flush the transmission or just drop the pan and change the filter and replace the fluid. I've heard with higher mileage I could run into problems with a flush.

You should be good to do a flush on it. If it has never been done then you might run a slight chance of bringing out a leak or 2. That's the only problem I've ever had.

if the tranny is going to go out it will. i would flush and change the filter. it will probably run 150 bucks at a quicky lube, but with the miles on it i would do both. lucas would probably be a good idea too

its and additive. the name is lucas transmission fix. i put it in all my cars with over 100k. good stuff especially when you suspect a possible transmission problem in the future. like brown transmission fluid for example. your tranny has been neglected and lucas might help it out some(with a fluid change of coarse)

Lucas, Trans honey, etc is a temporary fix for transmissions. To keep the correct viscosity and lubrication properties, unless there is slipping, just go with the recommended fluid. Don't do a flush. Do a new filter and a full fluid exchange. Many are very leery of flushes with unknown maintenance and high-ish mileage.

Stick with both. Unless you plan on taking apart the transmission. A full fluid exchange and filter change is impossible without a flush. As an owner of one of the quicky lubes. The flush machines used nowadays are designed to run off the transmission pump not create their own pressure. As lubricants and additives go. It's your call. The fluid required is more than enough. If you add the Lucas transmission fix it won't hurt. Is it required? I find in my experience a lot of additives are either a band aid to a problem that will eventually get to strong, or preventative measures to avoid those issues. Just take a side and go with it. But to some it up do both.
