2005 Ford Expedition

The posts on this newsgroup are astonishing. Where do your mechanics
come from? Get on with your maintenance, get it done. Change the trans
filter and the fluid, do not, I repeat do not let them talk you into the
reverse flush out. If you reverse flush, everything trapped in the
filter will be blown back through the transmission. (I change the fluid
& the filter every 50,000 - My F-150 has 200,000 on my truck with no
problems) I don't think much of your mechanics, they don't want to
change your plugs? Grab the bull by the horns and change the plugs.
It's challenging because you have to remove the coil from each & every
plug. When you re-install the plugs, put plenty of dielectric lubricant
on them before screwing them in.....

While I agree with the sentiment to resist the suggestions to reverse flush
the transmission, it is false that the stuff trapped in the screen will be
pushed back into the transmission. If the hoses are hooked up correctly, the
stuff in the screen will be the first to reach the transmission cooler,
which means it will be pushed out before it can get anywhere else.

I taken it to PepBoys and other local mechanics. The local mechanics say
they can do but it will take all day, plus the price they give me to fix
is the same as the dealer. PepBoys says I need to take to dealer cause
they cant work on my model.
I usually do car repairs myself but after hearing horror stories about
the spark plugs,  I dont want to get in a situation where I need to call
for help cause i cant fix and end up paying more than what I want.

You need to find a better shop(s), or go to the dealer to have the plugs
changed. Spark plugs in that vintage Expedition can be a problem, but Ford
dealers have the tools and procedures to handle replacing the plugs. The
local shop I use also purchased the necessary tools.

I'd change the transmission fluid, but avoid any sort of reverse flush. A
fluid exchange machine is fine, but not a reverse flush machine.

I will probably just take it to Ford and have them do it correctly.  Its
pricey but at least they will do them correctly. I dont think I have
much of a choice if I dont want to do and other shops I called wont either.

Thanks
