Hi, @Nsanendabrain ! I posted the codes below so those reading won't have to look them up.

@Mark Kovalsky may be able to help.

You say your buddy had just installed the transmission? Do you mean you bought the truck from your buddy four years ago?

Did he install a new transmission, a rebuilt transmission, or a used transmission? Is it a 5R110?

How long ago did it start making very soft shifts?

Something you can check until someone smarter than me chimes in -- The P1702 indicates electrical problems. Inspect the harness, especially where the plugs are. The wires can break inside the insulation.

Here is a picture and labeling of the 5R110 solenoids:

What are the Possible Causes of the Code P0730 Ford?

• Low transmission fluid level
• Dirty transmission fluid
• Shift solenoids
• Transmission mechanical problems
• Transmission hydraulic control circuit

What are the Possible Causes of the Code P2701 Ford?

• Faulty Overdrive Clutch Solenoid
• Overdrive Clutch Solenoid harness is open or shorted
• Overdrive Clutch Solenoid circuit poor electrical connection
• Faulty Powertrain Control Module (PCM)

Thank you @Jax .. Yessir, I bought the truck from him. The original transmission had gone out and he installed a used one from an 08, it is a 5R110.

It started the soft shifts a couple of weeks ago and progressed to slipping 1st to 2nd within a few days.

It has been parked for over a week now and I took it for a short drive yesterday, that's when I noticed the 1st to 2nd shift no longer slips but shifts hard, every shift above that is late shifting (higher RPM) and OD will not engage at all. TFT has always read generally around 160 degrees.

 

Thank you @Jax

Well, Mark has spoken! Are you up to replacing the OD solenoid? I'll bet there are plenty of YouTube videos out there.

From what I read, you pull the valve body. It seems simple.

Then you replace the OD solenoid.

 

P2701 means the OD solenoid is sticking. It does not mean anything electrical is wrong. Replace the OD solenoid.

The P0730 is almost certainly due to the bad OD solenoid.

The OD solenoid is used for the 1-2 shift. Second gear is first gear with the overdrive engaged.

 

I learn something every time you post! Thanks, Mark.

 

Here's a video with the valve body out.

 

Thank you for the link man, definitely helps give me perspective on what I'm dealing with. I'm just not sure which one is the OD solenoid, I would guess the TCC but I've never been good at guessing..

 

I have seen the 2701 code set before by a failed clutch piston or burnt clutch set. In my experience the PCM can’t determine whether the clutch didn’t apply because the solenoid was mechanically sticking or because it had a mechanical issue with a clutch set. The solenoid isn’t hard to change. It’s in the pan. Make sure that you get the correct polarity solenoid because there are inversely proportional and directly proportional solenoids.

as far as poor shifting across the board being soft, are you sure the filter did not become dislodged or is restricted? Did you pick up an early or late 08 trans? The filter on later models are different. The later models had an actual fine material filter in them where the early models had a screen basically kept out big chunks and had an inline external filter (similar to 6.0 powered trucks).

 

Thank you sir, I'm definitely gonna go the solenoid route and hope that does it. My biggest issue with that at this point is I'm not positive which solenoid is considered the OD solenoid, the TCC ? As far as polarity, I'm totally clueless.. I would assume I order whichever solenoid it is by transmission year model ? I remember him telling me that this transmission has an internal filter so I'm assuming it's the later model..

 

They all have an internal filter. The difference is one is basically a “screen” and the other is an actual filter. Here is a diagram

 

Thank you sir.. It's all a bit confusing as I'm trying to look one up

 

Plenty of YouTube videos to help.

 

I've never worked on transmission built for diesels before but I have a bit of experience with musclecar trannies. I suggest that you also replace the transmission filters at the same time as the solenoid. It is cheap insurance and should be easy to do with the pan already off.
We were in the practice of replacing the transmission filter every time we removed the pan in our performance cars. Like I said, cheap insurance and peace of mind knowing that all is well.

 

Hey guys, I've been battling the flu so I haven't even gotten started yet. I cannot for the life of me find the OD solenoid (solenoid B) online, I did notice while watching a bunch of YouTube vids that a few of the solenoids are the "same" as that one, does that mean I can order one of the others and it will serve the same purpose?

Could someone recommend a good brand or even better possibly give me a link to the one I need?

On another note, my '03 has the external canister for the transmission filter on it but when I got the truck I was told the '08 transmission I have has the internal filter and I didn't need to worry about the external one. I do plan on replacing the filter inside the transmission while I have the pan down. I honestly don't know if the external canister currently has a filter in it at all until I can finally get the truck in my shop. If it does have one in it I would assume it needs replacing, will it hurt anything to run both filters or would that be a plus?

I'm hoping I can drop the pan this coming weekend... I apologize for all the questions but I'm still learning on this thing and I truly appreciate everyones input..

 

First, the external filter you're talking about is a bypass filter, so while it's not filtering 100% of the fluid, it is filtering and getting the small particles out. It does need to be changed. Once you see all the crud it catches you'll understand why. Oh....use an impact gun to get it off. You can do it with a ratchet but you'll wind up bending the mount until it hits the frame and then you'll get out an extension bar, and then you'll be hitting that with a hammer. Impact gun takes it off in a split second. Just make sure you put it back on by hand and torque it down right.

As for the right solenoid, Ford used the same one in a couple different positions. The part number you need is 3C3Z7J136BA. You can see HERE that it's for 2004-2016 5R100 and fits the TCC, Intermediate, Low/Reverse, and OD.

 

I very much appreciate it sir !! All of y'all have been extremely helpful !! I'm going to get it up on the lift this weekend, I've got a few other minor issues to address while it's in here so it might be a week or so before I get it back out but I will definitely let y'all know the end result.. Fingers crossed..

 

I'm back... I'm trying to get the parts ordered for this thing, I'm finding everything (OEM OD solenoid (sspc-b) and internal filter for the '08 transmission) but I'm getting conflicting part #'s on the transmission cartridge bypass filter that comes on the '03 6.0... I'm coming up with 3C3Z-7B155-BA (#FT-145) and 3C3P-7C012-AA (also shows #FT-145). I want to make sure I get the correct OEM bypass filter, what am I missing or are they the same?

 

You want the 3C3Z-7B155-BA. I've seen both up close and personal and don't recall seeing a difference, but there is a reason one is recommended for certain model years, so I don't stray unless I know for certain it will work.....or if I'm willing to gamble. lol Some of the documentation says the second part number replaces the first, but I can't find anything saying it's compatible with the earlier years. Order the 7B155 and if they send you the 7C012 as a suitable substitute then you'll know it's compatible.

 

I appreciate it again Weatherlite.. I'm getting everything ordered today!!

I'm finally moving it into the shop this afternoon. I've gotta change the shifter cable first anyhow, I've had the new cable sitting here for over a year so I figure now is the time. Lol

 

After an extended delay I'm finally getting to this thing!!

Dropped the pan and the first thing I noticed is the cap on what Im pretty sure is the OD/SSPC

-B solenoid (the solenoid in which I got the code on) is non existent..

I know it's supposed to be there and read damage can occur without it, do I need to be worried about any other damage?

I did find one very tiny piece of plastic in the pan (seemingly part of the cap?) but nothing else. I'm not sure if the rest came out when I drained the pan or not..

 

The plastic cap itself isn't critical....it's the adjustment underneath that matters. Supposedly if the cap is off the solenoid can come out of adjustment, though I don't know how since it takes an Allen wrench to do it. But, I suppose it's possible. Either way if it were my truck I would just swap out the solenoid, inspect what I could, and button it up. Oh, don't forget to do new filter as well. Hopefully you have the '08 tranny pan to go with the '08 tranny so you can use the right filter and not that crap that came on the early models. That's one of the next things I want to do to my '04.

Good luck!

 

Yessir, it has the '08 pan and filter and I already have the replacement filter here waiting. I'm replacing the by pass filter as well and it's a good thing I am. Holy crap...

Solenoid supposed to be here tomorrow so fingers crossed, I should know this weekend if it fixes it or not. Thanks brother

 

Finally got it back together, cleared the codes, and made it 1 block before it started flashing the tow/haul light again. Showing the same codes so I guess I just wasted a lot of time and money. I have no idea where to go from here....

 

@Mark Kovalsky @matthewd11 Since he tried changing out the solenoid, with the P2701 code does that mean he's most likely got a burnt clutch?

 

Very likely @Weatherlite . Providing he installed everything correctly

OP, pull it out. It needs to be rebuilt. Or at minimum overdrive clutch repaired.

 

I appreciate the tags @Weatherlite ..

@matthewd11 , I definitely put it all back together correctly and triple checked everything. That's not the news I wanted to hear but I appreciate it man. I gave it my best shot..

 

Where are you located OP?

It is also possible there is an issue with the coast clutch drum. The welds are known to break occasionally (although with higher HP). The overdrive clutch is a holding clutch that stops the coast clutch drum from spinning. When the overdrive clutch is applied and the weld is broken the Sun gear on the drum will not be held to change gear ratios.

With the ratio code and friction element code it’s quite possible that is your issue.

 

@matthewd11 I live in LaVergne, Tn. just SE of Nashville.

I can do basics on transmissions and remove and replace them but as far as deep internals, I'm honestly clueless. Yall have been a great asset as far as diagnosis and I very much appreciate it..

 

If you were closer I could help you, but that’s a bit of a drive from New England.

 

@matthewd11 I wish you were closer as well but I appreciate it anyhow. Road trip?!! lol.

Alright y'all, I'm guessing replacing the transmission is inevitable at this point.

While I did triple check everything underneath the transmission before buttoning it up, I apparently had a duh moment while refilling the fluid and was reading the stick wrong. I have no reasonable explanation for that but it happened.

After adding another 4.5 qrts I am no longer getting any transmission codes or flashing tow/haul light, BUT...

It starts off fine, makes the first shift fine, makes the second shift fine (whatever gear that is) then that's it, no more shifts and no OD.

AT 55 mph I'm turning 2200 rpm and at 75 mph I'm running 3400 rpm. Obviously I have no OD so it's now parked in the yard where it's likely going to stay for some time.

Again, I'm not getting any codes now and it's not going into limp mode even with those issues. At this point I'm just going in circles...

 

Very same day as my last post the flashing tow/haul light came right back so I'm guessing that's that. I'm out of my league now and it's parked, thanks guys..

 

Did you check to see if the weld is broken for the Sun gear on the coast clutch drum??
