Trans ?
Hey all, I bought my truck about a month ago with 150k miles on it. I am not sure about the previous owners maintenance so i figured it would be a good idea to flush the trans. The mechanic i talked to told me that for some extra $ he would re ground the trans. He said that Ford does not ground there trans good enough and that it adds to the early failure of a lot of them. Has anyone heard of this or is he feeding me a line of BS to try and take some more of my $. Maybe it is common to do and i just have never heard of it. I dunno, i am new to this diesel thing and tryin to learn.
Thanks everyone.
Dustin

Not sure on the ground thing. Never heard of it. But i don't know much. But i would do the tranny maintenance. Pull pan,new filter, dump TC. the whole nine yards. I had my serviced for $119. Oil/filter/labor while i was having the TC changed. If your not having any trouble i would just do the maintenance.

Is it were they take a black wire & self tap screw to the bottom of the pan and run it to the frame or the negative post on the battery? 
And charge you $150?
Maybe someone else will have a grounding answer. But i never heard of it.

OK unless someone can tell me that this guy is not full of %#@$ i dont think i will be having him work on my truck. I will probably just do it my self. Is this what everyone recomends?
Changing ATF Fluid in a E4OD and 4R100 transmission .: Articles
This method does not stir up stuff that could be in there like a flush machine does that could lead to new problems, Correct?
Also i have read use merc 5 dont use it only use merc dont use it and on and on. What fluid do i use since i do not know what is in now and i assume some of it would mix with the new doing it this way.
Thanks again

I think that is an excellent write up.
I've done it many times. It doesn't stir up things in the trans, but then again, neither does a flush machine. Both the flush machine and that procedure change the fluid in the same way.
When it was written MERCON V was a no-no for the 4R100. Ford changed MERCON V and dropped MERCON, so MERCON V is now the right fluid.

I'm in the same boat you are -
Bought my '01 with 130K & no maint. records.
That's the procedure I plan to use.
I want all the old stuff out !
Start fresh.
I'll be buying a valve body soon, already have the cooler and 24 qts
of Mecon V. ($.50 off / qt at Auto Zone.)
Planning to do it all at once.

A couple of things. That is an old wives tale. Secondly, if you flush your trans way after it is due and you take poor care of your vehicle, you should not be surprised if the trans breaks. Usually people have a little issue with the trans and flush it in hopes of it fixing the trans and when it fails, the flush broke it.

You can add a ground strap yourself very inexpensive. With all the solenoids in today's trannies it is probably not a bad idea. Remember that your tranny and engine mounts are usually insulated with rubber. Make sure your engine has a good ground strap. There are problems when someone replaces a drivetrain and forgets to reconnect the ground to chassis.
