I'm working on a 2006 LCF which came from an auction so I have little information on its history. It's the 4.5l V6 Power Stroke diesel and has 132K miles. I checked the fluid today and it had good color and looked clean...except for the small black flecks on the dipstick. I'm figuring that's all friction material and means big transmission problems. Someone tried driving it today and complained about trouble climbing a small hill.
Anyway, assuming the transmission needs replacement, does anyone know which ones would be comparable? It's a work truck. It does tow some but doesn't do any mountain driving.
I moved you here as I don't believe anything in that truck relates to current SD Ford trucks.
Is it the 5R110W?
Does this truck have an OBDII connection?
I'm thinking it's stamped somewhere but I don't know which transmission it is. I think it does have a DTC code or codes but I plugged in my Innova scanner and it couldn't establish communication either with ignition on it with truck running. Check engine light is on but it also had no coolant so I'm sure was overheating. It sounds pretty good though when running. I did add some water before starting it but it was driven at least once for a short distance with low coolant.
Thanks guys for the responses. I doubt I'd even go for a reman but could get a used or even a junkyard one. I'd plan on removing the transmission filter cover to be sure the replacement unit isn't trash as well.
Which of the SD series years and models would be likely to have the 2006 LFC transmission?
It appears that was used in SD trucks behind the 6.0 and 6.4.
However, I would buy one that was in an LCF or a reman for an LCF.
Who knows what subtle differences there are.... Either none, or just enough to make it shift like two train cars hitting each other, or like a well worn Powerglide....
Looks like $1000 to $2000 on Ebay and other used truck places, or $3500 +/- from Advanced Auto and others.
I still can't make my OBD2 scanner talk to the 2006 LCF. I plugged in a different scanner today and got the same Failure to Communicate message. I did measure battery voltage at the lower left pin and some lower voltages on other pins. Anyway, no CEL on dash so maybe the overheating problem is the complete issue.
I did add 2.5 gallons of water or so but need to verify cooling system integrity. What is the system pressure spec and can I rule out leaks (including EGR cooler) with a system pressure test? I drove it about 10 miles today, mostly city but some freeway. Temperature was around 65 outside and gauge was at 185 on surface streets 190 or so on the freeway.
I did verify battery voltage at the cigarette lighter. As shown in the photo below, there is one fuse which lacks the small silver spheres visible in the other fuses, although it does have continuity. This is the second one up from the lower left.
You will NOT be able to "talk to" the PCM via OBD II. You need a scanner "talks to" Navistar truck engine controls using the round grey connector adjacent to the OBD II port.

I believe that's the transmission but one auction note said the transmission had been replaced perhaps 4 years ago. Would the stamping be on the underside? It does have an OBD2 port and I did measure battery voltage on the lower left pin. But, I tried two scanners and neither of them could communicate. On the plus side, there is no CEL on the dash. A major leak in the radiator leads me to believe someone left it outside on a cold Kansas night with weak or nonexistent antifreeze.

Although it does have an OBD II connector under the instrument panel, it is NOT used for scan tool communication to the PCM on this particular vehicle. As previously mentioned above, you need medium duty truck software capable of communicating with Navistar truck engine controls, connected to the grey round connector beside the OBD II connector, in order to scan this truck for codes or do any kind of diagnostics.
