Have you ever heard of this 'part' - "Lead Frame Assembly"Plus Update on prior thread

I took my WK to the dealership today because I was experiencing a shifting issue that involved my WK to act like it would not shift, the RPMS would climb and the trans range indicator on the cluster/dash had no response when I would tried the 'Auto stick". It would only stay in [D] only.

No CEL/MIL came on, but for the hell of it, I ran a scan and pulled a code - P2767, which is an Input/Turbine speed sensor "B" no signal.

I cleared the code and waited to see if I'd experience this issue again! Sure enough, it happened again, so I ran another scan to see if the P2767 would show up- and it did.

I have a power train warranty, so I took it to the dealership. They called me back and said the "Lead Frame Assembly" was the problem, and they would fix this, and I will not be billed, except for a $100 deductible.

So, has anyone out here ever hear of a "Lead Frame Assembly"?? What is involved in replacing this? Does the trans pan and fluid, need to be dropped?

Any info with anything to do with my experience with the shifting or knowledge of the Lead Frame Assembly is appreciated!!

Thanks,
-Tom

Yes, I have heard of the Lead Frame Assembly.

I'm pretty sure the valve body has to come out to get at it, so they will be dropping the pan and draining the fluid.

Not sure what other information you are looking for? The dealership has diagnosed what they think the problem is, and are fixing it under warranty. What else do you want to know?

Hi dr-

I have the Quadra I. If that helps. I cannot select what range for the 4X4.
It is always in high range 4x4. What I wanted to know, is if the pan, fluid and filter would need to be changed,
and I wanted to know what a 'Lead Frame Assembly" even was. I have wrenched on cars for years, and have never heard of it. Does it have anything
to do with the input speed sensor?
Is there another name for this part?

Yes the lead frame is a plastic assembly that houses all of the electronic circuitry in the transmission including all 3 speed sensors. The valve body does need to be dropped to replace.

I have an 08 Grand Cherokee and throughout the course of a week, I have been told that for $3300 1. the transmission rod, then changed to transmission rail, and then finally settled on the transmission lead needed to be replaced which is outside of the protection plan, of course. For them to fix it would be $1700. I contacted the Protection plan and was told that the claim was submitted for the Transmission Temp Sensor with an blank estimate of charges. Admittedly I know squat so I searched every part they listed and found the Temp Sensor alone for $12. Contacted the dealership back and they told me that the sensor is part of the lead and is not a separate part... my question is, is that true? I've been told several things in 9 days so not sure what to believe so before I commit to $1700, I want to know if what they are saying is true about one whole piece versus a component of one.

Not one code every was found per dealership nor did the check engine light ever appear.

What did you end up doing for this comment? This exact thing is happening to me. 2008 Jeep Grand Cherokee, they’re telling me it’s an $1800 repair and they are being kind of shy about telling me exactly what is wrong. I know what’s happening on my end, it goes into limp mode. But they are simply saying that one code they found on the sensor means the entire thing needs to be replaced. I don’t know squat about cars, however I truly don’t think that they can determine that the entire transmission circuit board needs to be replaced after pulling one code. The Jeep dealership won’t even explain what this means or where it is located, just that it’s “a part of the transmission”.
