Hi all. I hope someone can try to give me some good news on something that I did with my Taurus last week. I did a pan drop,Trans Filter/Fluid change to a 99 Taurus Se 24v that I just aquired from a family member. I used a no name Merc V (I am guessing my first mistake), well actually its Advanced Auto Parts brand Merc V. Now, I notice a very slight shutter at around 40mph. The vehicle has 75000 miles on it. And my dad claims the trans was serviced before. He cant remember when. (I hope around the 30000 mile mark). Is there a break in with changing fluid on a Trans? Would it beehoove me to change the fluid again? Its a long story but I actually had to change the fluid and filter twice (Within a day) I didnt like the way the filter originally sat in its fitting. It was way to loose. So I changed it all out again the following day. Its almost like I ended up changing all the fluid. The guys who read this are going to say "I would never let you touch my car" I cant even chuckle at this. I really went brain dead on this one. Should I change it again? Should I leave it alone? Should I add a friction modifier to it? I am one of those guys who always hear the slightest sounds coming from my car, You know the kind. Okay! Gotta fix it! Didnt you hear that? A backyard mechanic with OCD can be a dangerous thing? Can anyone help me please.. Thanks

Oh, I would not say you changed it too much, you might have gotton more stuff out, the second time you changed it.




I would, at this point if I were you, add a "bottle" of "Trans fix" by Lucas, the stuff in the white bottle. I used it in my 95 taurus, and NEVER had trans problems , in that car, and the trannys were WEAK in that year car!!


I would put a bottle in, about once a year, 10,000 miles, give or take. The car shifted funny, a year or two after I got it, and everyone else who had a Taurus, either was getting a "new" tranny, or getting ready to. It shifted a little weird, now and then, so I knew when to add the Lucas.



It wont hurt, and if it "fixes" the shudder, then fine, if not, you havent lost too much.

With the Lucas, do you drain a quart of fluid out of the pan, or, just add it to the exsisting amount thats already in there?

Every time I've changed my filter the old gasket ring stuck up in the tranny housing. Did it come out with the old filter or did you remove it after taking the filter out?

CujoTom

I removed that ring with a screwdriver and needle nose pliers. I also added a bottle of M/T friction modifier. The shutter is still there. As soon as 3rd gear shifts, its a slight shutter. Thats it.

I usually just added it to what was there, and it never went over the line, for me. There was a certain amount of "give" on the distick, if you know what I mean.



I did this with my 1995, adding a quart,, about 3 times, in 5 years, and no problems--- everyone else with Taurus's, said I was living on borrowed time, but it still shifted good, when I traded it in, a month and half ago.



And now with my "NEW" tranny, have not put any in this one , but might , just to be sure. The stuff worked for me.




When I deceided to put it in, the first time, the tranny was starting to shift SLUSHY, so, I had nothing to loose----and it kept the tranny going, for 100,000 miles, after I first felt the strange shift, -- I dont think that was " snake oil"!!!



Hey, if it dosen't work, you are only out 4-6 dollars!!! ( Depending where you buy it.)
