I have an Accent 2002 with over 100k miles on it. I want to flush the
tranny and was wondering if there is a "screw/bolt" (like the one on the
drain pan) i can use to flush it or do i have to do major work for that?

You can drain the transmission and fill it using the two drain plugs (one
on the pan, one on the differential) and refilling through the dipstick
tube. This will change about half the transmission fluid.

To do a flush (or fluid exchange), you'll need to remove the return cooler
line and place in a container to catch the old fluid. Add a couple quarts
through the dipstick tube and then start the car to pump fluid out.
You'll need to do this for about 12 quarts for a good flush. This will
replace almost all the fluid in the transmission. Repair facilities have
a machine they hook up to the cooler line that will exchange the fluid.

Although I don't understand why? most good auto mechanics (one, the car
Dr Ron Annanian) DO NOT advise changing the fluid or flushing on a high
milage car?Like I said I don't understand,but I do trust him.

The theory behind recommending not changing fluid is that very old fluid
will have metal particles in it and will result in higher friction than
the new fluid. When the new fluid is introduced, it can accelerate
slipping of the clutches.

By the same token, continuing to drive on the old fluid will acclerate
wear. If you've run your car too far beyond the service interval, the
damage has mostly already been done. It's then more a choice of which
method of failure you'd prefer.

I was told that a flush of the transmission would help my slipping problem.
Also, would additives help at reducing the slipping? The 'Lucas' brand was
suggested. Any ideas.

Thanks for the replies.
