Cluster Gear Display

[RoadBoss2]

Good day !!
I need to know if the 2012 1500 with a 65RFE , when shifting to manual mode , you see a "6" when pulling lever to "-" then 5-4-3-2-1 or
upshifting from manual 1 up if you see 1-2-3-4-5-6 then last "+" goes to D ?
Or is "D" act as the "6" then all other gear show by their number ?
Thanks .

D Allows any gear from 1 to 6. When D auto shifts to 6, it is the same as the manually selcted 6. If you use the gear limiter it will not allow the trans to shift above the selected gear. If you select 4, it will upshift and downshift between 1 and 4 but will not go into 5 or 6. If you select 6, works the same as being in D.

I believe D also allows MDS to be active, and in 6 MDS would be inactive.

True

I was wondering if the #6 would show in manual mode like an 2006 Charger SRT , it shows all gears in manual mode then 1 more bump to D where my 2008 Magnum RT does not show % in manual it just reverts to D .
Since my truck is not officially a 65RFE , it is 545RFE a 2011. But I tuned it to behave like that.
By the RPM it shows which gear it is in those graph
Maybe the question should be ask as: When in manual mode , will the 545RFE shift all 6 available gears ?
Last 4-5 upshift show highest gear on lock-up , but then in manual mode from D to - minus it show a 5 in cluster but it iiiiiiiiiiiiiiiiis in 1st overdrive the 4th gear it shifted from to 5 in auto ...
When manual shift down one more clic , it shows in 4th in cluster but RPM show Direct gear with lock-up rpm which is 3rd gear in a 545RFE
I hope I'm writing this clear enough.
** I just want to know how Cluster Display is supppose to show Manual gear selected .
Is it all grears 1 to 6 then another click up to D or is D also act as 6 ?

I am aware you have a 6 speed, but on the 8 speeds, that's the way they work. In ERS mode, can automatically shift up to the preset gear that indicated/selected, which shows anything between 1 and 8. Be in 8 and click + again goes to "D". When it does go into ERS mode (on my truck) , it also tightens up the torque converter lock up / increase engine braking and higher downshifting points. Seems like the ERS mode on the truck is like a "sport mode" on other vehicles that have that selection.

I suspect that some members may have the wrong idea about how the transmission functions when using the ERS switches.

I might be mistaken, but from posts here and there, it sounds like members perceive the transmission switches from automatic to a manual state.

As much as most of us refer to using the ERS switches as manual mode, the transmission is still automatically switching gears, but limited to not go beyond the selected gear displayed.

I have a ZF 8-speed, I'm not positive if the 65RFE and 545RFE function the same.

While I might tap the (-) ERS button a couple of times to force the transmission to downshift for rapid acceleration purposes, pressing the (+) button will not force an upshift. It simply limits the top gear available for the automatic transmission.

The following is from an earlier 4th gen owner's manual.


Electronic Range Select (ERS) Operation
— Eight-Speed Transmission

The Electronic Range Select (ERS) shift control allows the driver to limit the highest available gear when the transmission is in DRIVE.

For example, if you set the transmission gear limit to 4 (fourth gear), the transmission will not shift above fourth gear (except to prevent engine overspeed), but will shift through the lower gears normally.

You can switch between DRIVE and ERS mode at any vehicle speed. When the transmission gear selector is in DRIVE, the transmission will operate automatically, shifting between all available gears.

Tapping the GEAR- switch (on the steering wheel) will activate ERS mode, display the current gear in the instrument cluster, and set that gear as the top available gear.

Once in ERS mode, tapping the GEAR- or GEAR+ switch will change the top available gear.

1 — ERS (-) Switch
2 — ERS (+) Switch

To exit ERS mode, simply push and hold the GEAR+ switch until the gear limit display disappears from the instrument cluster.

WARNING! Do not downshift for additional engine braking on a slippery surface. The drive wheels could lose their grip and the vehicle could skid, causing a collision or personal injury.

There, changed manual to ERS. Manual was a misguided choice of words and put wrong ideas in folks thinking, but does indicate "manual selection of highest gear that the trans will automatically shift up to"..

Sorry for misswording .
-Because my truck is a 2011 , there was no 65RFE (Although it is the same transmission that they change sofware behavior and called it a 6 speed)
My question is just to know how cluster display the gears in a 2012 65 RFE click from D to -(minus) one click
** I just want to know how Cluster Display is supppose to show Max gear selected .
Is it all grears 1 to 6 then another click up to D or is D also act as 6 ?

When you hit the -, it will go down to gear you are currently in (1-6). When in 6, one more + gives you "D", which is all 6 automatically

Good on you for replying. Hope that answers what he wants to know. I could not for the life of me figure out what he was saying.

Picture the 6-speed automatic transmission.
It shifts up and down through the gears automatically as required when in the D setting.

Now, we add the ERS function, which simply limits the maximum gear that the tranny is permitted to switch into. Other than that, it's still an automatic transmission.

I will refer to my ZF 8-speed. I'm not positive if yours is exactly the same.

I'm cruising along at 50mph and press the Gear (-).
This will change the display to show D7-7
D7 is the current gear, and -7 is the max gear permitted.

If I were to slow down, the display would cycle through D6-7, D5-7... D1-7.
To terminate the ERS function, I could press the Gear (+) twice (7-8-D) or just hold that button for a few seconds.

If I were driving a bit faster and hit the gear (-) button, it would display D8-8.
In other words, the MDS would be disabled, and the transmission would cycle through gears D1 through D8, depending on the speed and load.

Theoretically, if I were passing cars with a limited area, I could tap the Gear (-) button a couple of times, which would downshift one gear lower than the present gear, drive the RPM up, and provide a bit more acceleration. In theory.

Sometimes when I'm driving home at lower speeds in the night, I use the ERS buttons to force the tranny into a lower gear. One route I take home has a long, slow grind of a hill.

The tranny is always looking to cruise at about 1100 RPM, and I believe that's too low for the grade. I prefer about 1500 RPM on that particular route.

I wrote this hours ago, and went out to run errands and snap a few pics of the EVIC.
A technical issue resulted in the pics being useless.

Or, we could point him towards the owner's manual, which explains it.

I'm sure it would have been much faster to screen shot or copy'n'paste from the soft copy of the owner's manual.

Or refer them to it.

I might have suffered a flashback from my working years when attempting to convey a technical concept to a non-technical employee.

I often enjoyed the challenge.

THIS! Was always fun back in the day. There were a few instances of leaving me wondering ...... "who tied their shoes for them!"

This has Escalated quickly !!!
-I'm not asking how the ERS works
-I was trying to compare how a 65RFE in 2012 would show the selection in the cluster vs a 545RFE in 2011
-Since I am tuning my truck with HP tuner and working to get all the gears to to act like a 65RFE ...
-I discover the trick , even if my PCM does not list the "65RFE" in the transmission type menu.
By enabling "2Prime" the logic sees it as one of its child and Bang !!!
-Cluster display show from "D" -6-5-4-3-2-1 the 2011 cluster is 65RFE ready since the display of ERS now shows all the digit 1 to 6 then one more "+" up to D before it was only 1 to 5 one more "+" up to D
-So with this last tweak to my tune by switching enable "2Prime" my cluster display the darn "6" as an ERs selection.
and the transmission will always upshift using all 6 gears
-I might not have explain myself very well ...
-NOTE , I will test the MDS action in ERS 6 and confirm that.

Thanks for your effort .

Quickly? LOL

If you ask a question and leave for more than 24 hours, expect us to discuss 12-14 different possibilities of what you were asking.

I'm glad to hear that you found a satisfactory solution.

No hard feelings here , it more funny than anything else.
