    My only concern is... I am not a mechanic extraordinaire. I tend to have my work done at shops or by friends. I'm not sure that is a job I can do in my driveway safely. If I'm taking it somewhere it would be a quick lube place that will hook it to the machine. That's $100. I'm also not sure that they are going to use the correct automatic transmission fluid. I'm willing to try the friction additive to get it to stop. I don't have the money to do the $100 change right now. If it will stop shuddering long enough for me to save up the money... Like 1 month from now... I will do the change then.

    As long as your fluid is fairly clean and glazed friction surfaces are the problem the Friction Modifier will fix it in just a few miles and it will last quite awhile......if it doesn't fix it you'll know you have bigger problems!!

    Ford Techs in Charlotte used to recommend the Friction Modifier treatment first and if it worked you could do a flush later........inexpensive experiment that WILL NOT HURT A THING!!

    Your issue is most likely the infamous torque converter clutch shudder. Adding the friction modifier will certain help in the short term, but it is a bandaid. If the FM additive is depleted, then so are all the other additives in the AFT that protect the transmission. Best course of action is to get a complete fluid exchange, using Mercon V only. Do not let anyone tell you they use some "universal" fluid with an additive to "make it into Mercon V".

    If you can't find a shop that will do a complete fluid exchange and replace the filter, dropping the pan and changing the filter is very simple, even for someone not "extraordinaire". If you can change the oil in the engine, you can do this. No special tools needed, just a 10mm socket.

    Bob.....it may be a Bandaide but I've seen it work for a couple years IF the fluid is not burned!!

    Like I said....it's an INEXPENSIVE way to find out if clutches are glazed....heck I put a bottle in my Marauder every 15K miles......NEVER a problem!!

    'jack, I didn't mean to disrespect your suggestion. It's a good way to see if the issue is caused by depleted fluid or if it's something unrelated to the transmission.

    My parts store didn't have the Ford friction modifier. They pointed me this direction. It seems to have fixed the issue.

    I figured that. I'm going to have the fluid changed this coming Friday. I'll put the original Mercon V in it and call it a day.

    Why not get parts and service at the Ford dealership?

    I don't want to pay the exorbitant labor rates when I can do the work myself. I have a buddy that used to own a shop that knows exactly how to do this stuff. He's going to help me out. Free labor.

    I was just referring to your comments comparing the correct friction modifier vs whatever the parts store has, or the quick lube fluid change that may not use the right fluid vs the Ford dealer's service dept that knows which fluid to use.
