Finally a Ford TSB to Try and Fix our Transmission Problems (TSB 24-2046)

[SeaRanger]

So a really common problem I'm seeing with all of our rangers is ROUGH and Delayed clunky shifting. I'm also seeing that alot of ranger owners have to replace their transmissions before they reach 100K miles. This sucks. You can bet this harsh delay and clunky shifting is a contributing factor to the short life span of our transmission

A brand new technical service bulletin (TSB 24-2046 ) was just released a few days ago on February 22, 2024.

Title: 10R80 Automatic Transmission - Harsh/Delayed Engagement And/Or Harsh/Delayed Shift - Non-Main Control Break-In Capable

Issue: Some 2017-2020 F-150, 2018-2021 Expedition/Navigator/Mustang, 2019-2023 Ranger vehicles equipped with a 10R80 transmission may exhibit a harsh/delayed engagement and/or harsh/delayed shift. This may be due to the transmission solenoid ID strategy, sticking valves in the main control valve body and/or axial movement of the CDF clutch cylinder (7H351) sleeve. To correct the condition, follow the Service Procedure to identify and correct the condition.

I've attached the TSB document for you to see but to me, it looks like a BUNCH of work on the transmission. There's even some language for newer/low mile vehicles to have a complete transmission replacement. Not some little gasket or plug and play replacement. Someone smarter than me can look at it.

CDF Clutch Cylinder Replacement

NOTE: For Mexico, USA and Canadian vehicles less than 3 years old and has less than 36,000 miles (60,000 km) the dealer has the option to continue with this TSB repair or replace the transmission under the low time in service (LTIS) policy.

1. Remove the transmission and mount the transmission to the bench. Refer to WSM, Section 307-01.

2. Disassemble the transmission. Perform only the necessary steps to remove the clutch and planetary assembly from the transmission case. Refer to WSM, Section 307-01.

(1). It is only necessary to remove the torque converter, transmission fluid pan and gasket, transmission fluid auxiliary pump (if equipped), fluid filter and main control valve body assembly, all 4 speed sensors (intermediate speed sensor A [ISSA], intermediate speed sensor B [ISSB], turbine shaft speed [TSS] and output shaft speed [OSS]), transmission fluid pump, front support assembly and the clutch and planetary assembly. Refer to WSM, Section 307-01.

3. Disassemble the clutch and planetary assembly. Perform only the necessary steps to remove the CDF clutch cylinder and the No. 3 sun gear shaft and No. 2 ring gear assembly from the clutch and planetary assembly. Refer to WSM, Section 307-01.

5. Disassemble the C, D and F clutch assemblies from the CDF cylinder. Discard the CDF cylinder. Refer to WSM, Section 307-01.

Note the CDF part number for the Ranger is JR3Z-7H351-B (I believe the redesigned one is the 'B') and the one for the F-150/Expedition/Navigator/Mustang is JL3Z-7H351-B a slight distinction.

What I perceive is that a best case scenario for those of us beyond the warranty period and without an extended warranty is to 'negotiate' a replacement transmission if the owner covers labor. It doesn't seem totally fair but I think it's what Ford feels they are able to offer from a financial standpoint.

I contemplated finding a shop that would build and install an upgraded version, not just a factory replacement but really haven't gotten anywhere. Suncoast down in Florida seemed to be the best custom shop and I had contacted them before. They insisted I didn't have a 10R80 and I sent them my VIN to prove it but they never followed up.

Their transmissions start around six grand.

Our transmissions don't need a ton of performance parts like 1000hp Mustangs but there are some areas that can be improved for durability.

 

[ControlNode]

LOL, of course that comes out when I'm at 38,000 miles.

 

[NotBudule]

My 21 with 14000 miles , which has been clunky since day one , could sure use this ? but how to force dealer to do it is another issue ?

This TSB supersedes 23-2350. Looks like there’s some verbiage change in the issue and procedures . Will have to read through it to find the exact changes but up front it looks exactly the same.

They're gonna have a tough time finding 2019 Rangers that are less than 3 years old.

Transmission is 5 year /60K

 

[Stevedbvik1]

Quick glance at the 24-2046 shows it to read pretty much exactly as 23-2350 with updates to wording for following procedure steps. But no big changes from 23-2350 that’s been out since November of 2023

 

[Stevedbvik1]

But thanks OP for posting the update ?

 

[Dr. Zaius]

Transmission is 5 year /60K

I realize that.

I was jokingly referring to the above quote since it applied to 2019 through 2023 Rangers:

So a really common problem I'm seeing with all of our rangers is ROUGH and Delayed clunky shifting.

I would be careful using terms like "really common problem" and "all of our rangers". Those are very absolute statements. This forum and others represent a small percentage of the vehicles out there. And, not even everyone on this forum has had issues. Is it an issue, yes. Is it a 100% for sure that yours or anyone's transmission is going to fail, NO.

For those that have had or have issues, it is a big issue. Those people also are the ones who go on forums and other on-line venues and make a lot of noise about their problems.

My late year 2019, which put it in the prime time frame for the CDF drum issue, drives and shifts just fine, with 33K on it. Does the possibility concern me? I'd be foolish to say no. Am I loosing sleep at night, NO! I am taking precautions, like changing the pan and doing regular drain and fills. I installed the Fitzstik dip stick so I can monitor the level and fluid quality.

Is the 10R80 perfect, no. Name another one that is. With anything as complicated as our transmissions and trucks there is going to be issues.

Just be careful when you use absolutes in your sentences as it shows your emotions coming through.

I also have a late 2019, and I'm at about 42k on it. It's been in the shop for the hvac box repair and I just got it back. Noted how smooth the transmission was on the drive home. I had the TSB done way back when that was just a software thing when I was experiencing clunky shifting on cold days when the engine was cold (and it would smooth out after it warmed up). Since I had that tsb applied, my transmission has been pretty buttery.

? got it. But those out of that 3/36 still qualify for the repair( not replacement )if under 60K miles

Actually, the way Ford is handling issues, it wouldn't surprise me if they posted that a replacement was free for any 2019 Rangers that were under 3 years old ?

Hopefully this could be a sign of Ford turning around some things.

They have a few class action lawsuits on these 10R80s. These TSBs are more evidence that these transmission have problems.
