How to install valvebody, and butt dyno testing

This is for installing a Ford Racing valvebody (M-7100-FVB) into a '05 focus, with a 4F27E transaxle. Other years, and valvebodies may be similar.

These are pages from Alldata, and a few pictures.

Tools needed:

8mm socket
1/4" ratchet
in lb torque wrench
brass, or plastic pry/scraper
funnel
drain pan
jack, and jack stands



Parts needed:

valvebody
6 qts mercon V (used 5 1/2)
gray RTV sealant
trans filter
I bought VB gaskets just in case, but didn't need them.











See the size difference? There are only (2) longer bolts, and they are #3, and #4 on page 5



These are the (2) accumulators. You'll have to hold the valvebody in place when removing the last bolt, or they will fall out.



They go back into these holes.





See this thing? (Manual control valve shift lever)



It goes in here. (Obviously the long end is in the valve body, not in your hand.)





Before installing new valvebody, I had to transfer these two O-rings over to the new one. I checked the torque (80in lbs) three times. The second time around, a few weren't in spec. The third time, they were good.



Plug the connectors back into the right solenoids.

Butt dyno

It does seem to have firmer shifts @ WOT. And, a slightly better shift feel during nomal driving. Of course, this could all be in my head. The next time I get out to the track, I will update this thread with the results.

I've installed the Lentech valve body into a Zetec (looked like exactly the same process) and WOW did it firm up the shifts!

I kinda figured they would all be the same, just wanted to play it safe.

Wanting to let the RTV fully cure before I beat on it, I took it easy yesterday. But, today was another story! Checked for leaks, and the fluid level...yada yada... Then WOT everywhere I could. Definitely a difference! I can't wait to test this out at the track. I did have a tune already, and was told that I wouldn't have to get it retuned for this. Not sure how this would feel without a tune. But, I like it!

the only thing i would have changed is to use synthetic tranny fluid. it should help it stay cooler.

One thing, we used the rubber pan gasket only as RTV sealant is usually not recommended on automatic transmissions in case a piece breaks off and lodges somewhere. IDK if it changed on the new models (as in no gasket) but that's the general rule..
