Hi all. Just did an '08 transmission pan/filter upgrade. I also put in a PTP Modified Direct Clutch Solenoid.
This is a straightforward job. I am doing this quick writeup to help anyone who is doing it next.
The parts/price list is:
- '08 Pan is Motorcraft 8C3Z-7A194-B - I bought from Sunrise for $65
- '08 Pan filter is Motorcraft FT180 - I bought from RockAuto for $36-discount
- 03-10 TP filter is Motorcraft FT145 - I bought from RockAuto for $22-discount
- 3 gallons of Mercon LV - I bought from Meijers ($16/gal, I think)
Note: I reused the pan gasket. The Motorcraft FT145 filter does NOT come with the housing o-ring. I reused that too.
Step 1 - Run it to temp
Ummm... run it to temp. That's it.
Step 2 - The external filter
The external filter in a canister not unlike an upside down oil filter canister. It is straight back from the passenger side lower radiator corner.
Here is a pic:
That is not my truck. Too clean. My pic did not turn out well.
When you pull the external filter housing/cover off, use an impact. It is not on there very solidly, so cranking on it with a ratchet will bend the lines. It's prolly 22mm, but 7/8" was pretty much dead on.
Just remove the cover. Pull the TP filter off. Move the spring cap from the bottom of the old filter to the bottom of the new. Put the new one in place. Lube the o-ring with some trans fluid. ...and spin the housing cover back on.
Step 3 - The pan/internal filter
First, drain the fluid from the plug (13mm) and then pull the 20-ish pan bolts (10mm). The pan drops easy with not much mess.
You pull the internal filter out by pulling straight down. When you pull the filter, more fluid will spill out, though. There is a orange seal that is around the neck of the filter. This is what it looks like:
Like other instances on these trucks, you need to fish the old one out before putting the new one on. I had to.
Here is the old and new pans/filters side-by-side:
Pan is slightly taller but there really is a huge difference in the filter.
Step 4 - Modified Direct Clutch Solenoid (optional)
This solenoid is the middle in the bank of three. This pic from the installation doc shows it:
You just pull the capture clip, unplug the solenoid, slide it out, slide the new one in with the connector at 6 o'clock, turn it to 7 o'clock, reclip and reconnect.
Step 5 - Pan installation and fluid fill
The pan is light and easy to put in place. As stated, I reused my gasket. I moved around while tightening loosely to be sure that it settled. Then moved around again while torquing to 11ft-lbs.
Filling stinks because Mercon LV stinks. Literally. Don't say that you weren't warned.
I filled the amount I drained and then added as needed. Easy.
That is all. I have been driving around and have not noticed the hard shifting that some have mentioned with the solenoid swap. It just shifts smooth and nice.
