Nothing special, just sharing what I found and what I fixed.
First off, my symptoms:
- Wont shift to higher gear after a downshift (ie. 5th to 4th, 4th to 3rd)
- Loss of ALL gears except manual 2nd/1st when at a stop
- Regained ALL gears for a short period (1- minute) after vehicle restart
- Regained ALL gears for a longer period (20+ minutes) after full vehicle cooldown
- Transmission "limp" mode engages while flashing OD OFF
Parts bought:
- EPC solenoid XL2Z-7G383-AA
- Valve Body Service Kit (Ford TSB Valve Mod) 3L5Z-7M203-JA
- 98/00 4.0L SOHC Valve Body Separator plate 1L5Z-7Z490-HA
- Revised bracket - XL2Z-7L491-AA (I bought this before tearing into my trans. I later found my transmission already contained the bracket. I changed the bracket anyways.)
I replaced both the separator plate and EPC Solenoid, and performed the Ford TSB Valve Mod(Thanks out to Glacier991)
Now to all of you with the same model as me - 1999 V6 SOHC XLT - the cat is below the transmission pan, making it impossible to drop without unbolting that section of exhaust pipe OR unbolting the crossmember that supports the transmission-transfercase. My exhaust pipe bolts were rusted into place and rounded so I dropped the crossmember and unbolted the manifold-pipe bolts instead. I then could slide the pan towards the transfercase.
After dropping my pan I then went onto the valvebody. THIS VIDEO helped me figure out dropping the valvebody and replacing the seperator plate - BUT I DO NOT recommend using airtools on the valvebody like he did, much too fragile in my opinion.
Upper part, whats above the Valvebody after removal. Nothing special here but Id thought Id take a picture anyways to show.
Found my problem. Facimeor was right "Whats more likely... a VB gasket or servo seal blowout." The gasket around the servo blew out pretty good, Im surprised I even got 20+ minutes out of it each cold start. Blowout can be seen at top right.
I finished the repairs and valvebody is now back in the trans. Since Im doing this at college during class, I ran out of time today. So Ill finish up Monday and let everyone know how it goes.
Torque:
- Valvebody bolts - 70-90 in.lbs
- Separator plate torx bolts - 62 in.lbs as directed by Ford TSB Valve Mod instructions
- Transmission pan bolts - 10 ft.lbs
