sea foam

Is it ok to to add seafoam to my tranny before i change the fluid and filter or should i not even worry about doing it 7.3 2001

I wouldnt add anything, seafoam is another snake oil product. It may have some
limited specific uses, but I would nt use it as a general "cleaner"

Problem with the trans is that som eof that stuff you do not want to mix around. That
is the reason you never want to flush the trans. Just drain the oil and let
teh pump push out the old stuff in same direction it always has. Way to
many posts of tranny flushes and then they fail 5k later.

I've never heard of it!

That is BS!!!! Internet MYTH!!!!! Yes it is true that on some auto trany's that have gone long durations without maintenance that a power flush can cause the trans to fail sooner. This didn't cause the failure, it just made it apparent sooner. Supposedly all the old cluthc material and what not is what is holding the thing together. But this isn't a issue when you do proper flushes and the proper intervals!!! This is another one of the internet myths that seem to spread like wild fire, that and the CPS will cure any problem on the 7.3!!

Another very good product--> Lube Control

The only time I have ever used seafoam, is when I change my fuel filter. I pour in 1/2 a can into the fuel bowl, then install the new filter.

I'm calling Bullsh*t!!!!!!!!! I've used Seafoam for years. Don't use in trans. though. I add to my oil about couple hundred miles before I change it. I add it to my fuel everyso often. I own a jetta tdi as my commuter car, tdi owners will tell you to use it religously. Added to the fuel it keeps the intake from getting carboned up.

Well I just ran Seafoam trans tune in mine. From what I read, you dont want to run those type of cleaners and not flush and change the filter. They say that the additives can loosen stuff up and then clog the filter later down the road. I ran seafoam for a couple of days, then flushed the fluid and changed the filter. Seafoam is not a snake oil. I have been using seafoam in my gas cars for a while now in the gas, oil and trans with no problems. It has always made a diffeence after each use and is the only general pupose additive I use and never a problem. Just be careful how you use it and follow the directions.

If you have no problems with the additive, you would have had no problem
without it. Regular service is all your vehicle needs. All the "magic fluids" just
move money from your pocket and make you feel like something was done. I have seen
engines ruined from additive, all of them "cleaners". They moved sediments around and
clogged galleys, end up with burnt bearings and the such. Regular service would have
not allowed the sediments to form in the first place.

Just like changing the HP oil, but could cause problems.

Yep, I believe it has. Get jug of Marvel Mystery oil while you are at it.

I am sure they are all tested for the modern seals and materials in your PSD.
