Been talking to several people on the other forum. The shift light (performance shift indicator) is only functioning on one person's vehicle. Mine has worked on a handful of occasions. Is anyone here seeing that issue and/or have found a solution?

FCA/Stellantis is aware of the issue and as usual are dragging their feet. Nothing yet. I personally would just wait for them to provide a fix.

Thanks for the info Fran. Can you point me in to something that verifies they are aware of this? I (and several others) have been working on this for about 5 months and so far I've been able to get Dodge to confirm they even know they have a problem. I've been in a bunch of back and forth with Dodge Cares and dealer etc. My dealers technical contact talked to someone at Uconnect who told him that it wasn't supposed to be offered on our models and the next software update would remove the shift light screen. Do you have a STAR case or tech note I can reference?

They will probably never fix it. On my son's 2018 M6 Hellcat, it worked for about a month when new. But, not all the time. He asked the service manager about it during the first scheduled oil change. The answer was that it's not supposed to be there anyway. Now that the car has 72K miles on it, it has only worked a handful more times in all those miles. He don't miss it and don't care. Now we both see it as a worthless gizmo. Others may want to pursue a different answer.

"It is not supposed to be there" yet it is right on the window sticker.

I called Dodge back in March and the woman confirmed it is there and should work.

Correct. However, my son decided if it were going no place complaining about it, it wasn't worth the effort of pushing them to fix it. Sometimes PCM updates screw up something else. Case in point, Microsoft. All automatic updates are disabled on my server farm until I run updates on a system where all updates are treated as beta even though Microsoft says it works. I would think after all these years that have passed, Dodge software writers would have figured this out. I hope those of you who want it to work will be successful getting a resolution.

Fair enough, semantics, right? And if you read my OP I said wait. If you truly think they "do not know about it" I will say ok. But they do and it sucks that they are allow to play this game. That is why we have Class Action Lawsuits and it sucks. The MFG should be responsible and they are legally bound to be in a twisted kind of way by their own damn fault.

Supposed your son got his car delivered to find out is was only a 392 and not a 6.2 SC? While you might think "well that is different", no it is not.

These PCM's contain thousands of lines of code. Possibly, the person who put the hook in the code to flash that yellow light for optimal shift points depending on accelerator pressure died or moved on to bigger and better things. I used to write firmware for SAN controllers on Enterprise networks. Debugging a trip wire in the code can take longer than writing the actual code itself. Even if there is a class action law suit, it's very hard to get them to fix it unless it's a safety issue and escalated to NHTSA. And because it is NOT a safety issue....

So here's the latest from Dodge. Took mine in Thursday to get the STAR (Service Technical Assistance Resource ) case started. Dodge got back with the service tech (Diego) Friday. According to what Diego was told:
They ARE aware of the issue.
Despite what others have said and what he was told by someone at Uconnect previously, they acknowledge that is IS supposed to work.
They have worked on a solution (a bit about that further down).
The issue has something to do with failure of the clutch pedal switch and PCM to properly communicate.
He was told that a fix for the issue was rolled up in the same update that made changes to the valet mode (I got a note on the valet mode update in the mail as I think all owners were supposed to)
He was advised to install that update to fix the issue. He did call me to ask which one of the two options I wanted installed as there is one version that limited the maximum speed to 25mph and one
that limited output (not really sure about that last detail) but I opted for the later (I could see an issue if the valet had to park it down the street and then couldn't get out of the way of traffic).
He installed the update and informed Dodge that it did NOT solve the issue.

Today I went to pick up the car from the dealer. Headed to the grocery store a mile or so away and got on it a couple of times and noted that the light did NOT work. Left the parking lot and noted that it still didn't work. Somewhere on the drive home it came to life. Will post the video. Pulled over, shut the car off, opened and closed the door and restarted. Light still working.

The clutch switch has nothing to do with the shift light. On one of the club cars that it has always worked on, he normally shifts without using the clutch once he is past 1st. gear. The shift light still comes on depending on acceleration curve. Try it. It works.

An answer from an expert :rolleyes:.
Actually, the clutch switch does have something to do with it.
The shift light shuts off as soon as you depress the clutch, even if the accelerator pedal is to the floor. Try it. It works.

It also goes off if you don't use the clutch. The PCM knows the car is in another gear because it knows the difference between the engine speed and the road speed. I checked it out last night as a passenger in one of the club member's M6 Hellcat. A caveat to this is that in his vehicle, he has the clutch switch disabled so it will start without having to depress the clutch. Just the way it was in the old days. But anyway, after the test drive, he shut it off because his wife don't like it flashing in her face when she drives the car.

I got in a bad habit in my teens of turning the key and kicking in the clutch ('76 dart). Hopped in the '75 Toyota and did the same. Fortunately there wasn't anything close in front.

Disabled the active exhaust (always full open) and now MY wife doesn't like that.

Since I hate to lose a debate:
Got in the car last night and put it in neutral with the clutch engaged. Revved it and shift light comes on. Kicked in the clutch and light goes off. So the clutch switch DOES interact with the shift light program.

It did, but strangely not right away. Dealer drove it without it working, I drove it once without it working and it started working about 20 minutes into my second drive. One guy on the other site reported issues with the update.

"Mine has been working since I first noticed it but of course my car throws a code about every 3 days since I got the valet update. I use it about every time I park though. "

I've never put mine in valet mode and don't think I'll attempt it based on his experience.

My son had his driveshaft replaced on the Hellcat last week $$$$$ WOW! While the car was at the dealer they did the update. It also included some kind of evap canister purge valve flash that he was supposed to have done a long time ago. But anyway, 2 fixes plus the new driveshaft. 72.5K miles. I'm going to ask him tonight if he will enable the light and see if it works. Regardless, the service dept. should not screw around with people's cars and do things that the customer did not ask for.

So... my Son turned on the shift light before he left work last night. In 42 miles of mixed driving, part highway, part heavy city traffic, the shift light came on only 3 times. It is now disabled again for good. However, he loves his new driveshaft. BTW, the service manager claims that the new driveshaft will last the life of the car because of a re-design they implemented.
