Can I add non-slip transmission additive to Lincoln ls

You do not put anything in any transmission except
the correct fluid

In your case Mercon V

Your trans is done,worn out,need a new one.

Fluids & additives fix NOTHING

first locate the dip stick for the transmission under the hood, after that start car and let run for 1 min,( car has to be running to check transmission) pull dip stick out and wipe it off the stick it back in and check the level again, if it is low you will have to pour the trans. fluid in thru the dip stick hole, add a little at a time and continue to check fluid level until it reachs fill mark on dip stick also the do not make a manuel for the Lincoln LS you can order a disk from Helminc.com that covers all related thigns for this car I had to order one for my LS good luck

If you have no leaks,get under it & check it over

Then you have a bad Pressure Control Solenoid Pack
inside the trans pan,common on an LS

IF,I repeat IF,it is has been slipping at all & you drove
it at all,even a couple of days,your done,the trans
will have to come out.

I have an LS & also once own a trans repair shop

Now I fill mine from a 3/8" Allen Plug on the rear extension
housing

The factory way is to remove the 1/8" pipe plug in the center
of the trans pan oil drain plug

Either way you have to have a special container for the fluid
& compressed air to blow it in there.

Thanks for choosing FixYa and welcome to the site. You need to look on the engine and find the transmission dip stick. You can add the fluid there.

no , i dont think it will solve your slipping out of gear, call dealer or trans shop, they will usually check for free.

the transmission is sealed so you shouldn't have to add fluid unless there is a leak find the leak first to add fluid there is a bolt on the right side of the trany i think that's where you add the fluid but you will have to use a pump because of the angle.

you might want to have the filer and fluid changed in the transmission.

look for the red dip stick its usually in the back area ,,the best way to fix that is to use a quart of lukes transmission slip and sealer it is the best on the market and coast about 11 dollars that's a way to start first ...good luck hope this will help

Try some lucas in it. If it has less than 100,000 miles or so, do a trans. service and add 2 bottles of lucas trans. additive. (from napa).

Ford has been using a brass screen filter for a long time. It's not non-servicible but is easily removed and washed off which is likely what they did. Generally if the filter becomes plugged up it is from debris caused by a failure, at which time a rebuild is necessary and filter change would not cure anything
Hope this helps!.
