Has anybody tried to install the GMC MultiPro tailgate on a 1500 Silverado yet?  Briefly glancing at the curvatures of the tailgates for the Sierra and Silverado, it looks like it would be a direct bolt on.  Any takers?

I wonder if the upper latch would work correctly.

Where would you get all the special wire harness hookups needed for that beast? Power, remote release, in cab release.....

Don't need the in-cab function and I don't need the remote function.  All I need is the handle function and it will have power from the same source as my current tailgate.

I'm parked next to a 2020 Silverado at work today. We popped both and it looks like it would be a direct swap. 

 

With that said, I work with my truck, and the only time I've ever used the "MultiPro" part of my tailgate or the speaker system was to show people that asked about it and to help my GF get into the back. If I had the option today I definitely would have just have a regular (lighter) tailgate.

I use it to be able to have my dogs in their kennels when pulling my travel trailer and I can use it to get the tailgate fully down. Its pretty awesome..

Have a question about this. Even if you just power it up directly, I'm guessing you'd also lose the locking feature of it? It normally acts like the door locks. They won't open unless you have the fob in the vicinity. 

 

There's no other provision for a lock, so if that's important to you, I'm not sure how you'd get it to lock in place.

But surely the Silverado tailgate is power locking? Why would you lose that?

The harness may be different. If the multipro has its own cable for the inner gate you may still be able to use the lock and camera, otherwise it would be cutting the connectors off and making your own for camera and lock

I was just mentioning it as a question. Where is the remote receiver? In the tail gate or the truck? Reason I ask is that if the receiver is in the tailgate, you'd have to swap your receiver from the Chevy tailgate to the GMC one. Otherwise, your fob won't allow you to open the gate at the push of the tailgate button. But if that were the case, your remote and dash button should work on it also. I'm not familiar with the wiring and sensor locations for the gates.

 

If the release solenoid gets power from a separate source that needed to be wired in separately, then the locking feature would be lost as you couldn't remotely operate it and the fob would have no effect.

 

Maybe my truck is different? I don't know. I do know that I cannot walk up to the doors or tailgate and get them open without the fob in my pocket or nearby. So if the receiver from the fob is in the truck to activate the tailgate, you should be golden. If it's inside the tailgate, you may need to change that out.

 

I have no idea about Silverado tailgates and how they operate. I've never looked at them.

I definitely need the key fob on me, or within very close proximity, to open any door on my truck.  I would assume there is either a receiver in the tailgate or within very close proximity to it.  The signal receiver is an interesting point that I hadn't considered and the location of the said receiver would need to be verified.

The antenna for keyless entry of the tail gate is located behind the license plate in the rear bumper of the vehicle.  On models with keyless entry, there are five antenna, one on each door and one in the rear bumper (as shown below).  So the keyless locking and unlocking actuation of the tailgate should be retained regardless of the tailgate, assuming the connectors are the same.

Excellent info to know.  Especially will come in handy if you can find a Multi-pro in your color!  I would IMAGINE (no proof) that the upper center solenoid is simply piggybacked off the harness for the main gate solenoid so plugging up the power from the truck pigtail will be a one and done. Also, does the power lift on Silverado allow the multi-pro to work? Or is power lift an option? Like I said, I'm not very familiar with Silverado. 

 

The secondary gate on the multi has only the push button on the back of the tailgate only. No remote. I'm also guessing the main gate latch points are the same between Sierra and Silverado? If it fits, it ships!!!!

So my tailgate doesn't power up or down, but when I use the keyfob or the button on the center console, it opens and lowers on its own (Spring assist and friction impeded I'm sure).  However, the Rear Gate Module required for the power assist tail gate is less than $300 so thats not a real issue. 

 

What I'm trying to figure out now is if the assist motors are internal to the tailgate or external and if external, they would need to be purchased as well for an additional cost.  If everything is internal to the tail gate, I think it would be best to find one in a junkyard and purchase as a complete unit, mount it up, and roll on.

 

Really, I just need somebody to volunteer their time and finances to figure this out and get back to me, HA.

Since I already own my "Last Truck" as my wife puts it, Anyone know if the multi gate will fit my 2015 2500HD? I can figure out the electrical, just want to know if it will fit physically.

      Another 6.2L engine failure!

      By MASONV88888888 · Posted

      My 2025 Silverado 1500 had to receive a brand-new engine (long block) under warranty last month at only around 16,500 miles. Before the replacement, the truck repeatedly displayed "Engine Oil Level Low" warnings, even though the Oil Life Monitor still showed around 50% remaining after about 6,000 miles since my last oil change. After seeing the warning several times, I checked the dipstick with the engine cold, and the oil level was completely normal. The next day, the message escalated to "Add Engine Oil." At first, I assumed it was just a faulty oil level sensor, so I brought the truck to the dealership. After inspecting the engine, they found internal cylinder wall scoring and ultimately replaced the entire long block under warranty. Before this happened, I was planning to install a 4-inch lift and suspension upgrade on my truck. After needing a new engine at just 16,500 miles, I honestly don't see the point anymore. I also contacted GM to ask whether my vehicle qualified for a buyback, but I was informed that it does not at this time. Anyway, this experience has left me with serious concerns about the long-term reliability of this engine. I sincerely hope NHTSA expands the current investigation or recall to include 2025 model and performs a thorough inspection of affected vehicles. My biggest concern is that these engines may fail shortly after the powertrain warranty expires. If GM truly stands behind this engine, then at the very least, please consider extending the powertrain warranty to 10 years for affected owners. That would go a long way toward restoring customer confidence.

      OCI, not when but why?

      By Grumpy Bear · Posted

      Without exception but then I'm the odd duck, right? I know what goes into that test, how it is calculated and thus how to beat it. But EPA values are often not beaten by the general public and the government has in past years adjusted the means and methods to come to those values to more closely approximate "Joe Average".    The only real trick to beating that EPA average is don't drive like "Joe Average".    It's the same method you used to profit from "Economic Migration" and in doing so beat the 'stats'. But you, like me, are not "Joe Average".     The thing you don't seem to grasp is this "Purchasing Power Index" isn't forward looking. It doesn't predict what it going to be but looks backward and states what it was. They are not telling us what the THINK, they are telling us what they MEASURED. Example:    Wife says "I'm going to lose 40 pounds by Christmas". May she does, maybe she doesn't but the doctors office who weighed her when she made that statement and again at Christmas only REPORTS what the RESULT was. You and I can banter about what was possible and what aunt Tilly did till the cows come home but the result is the result. Arguing otherwise is.....irrational. That's all I'm saying. This isn't about:      What you are calling a 'Statistic' is a RESULT not a CALCUATION and as a result the RULE. Like gravity as a rule, it can not be broken.

      Rattle in the rear!

      By MASONV88888888 · Posted

      Just wanted to say thank you for posting this. Years later, your thread is still helping Silverado owners.   I bought my 2025 Silverado 1500 in January 2025, and I've had what feels like the exact same rattle since day one. After reading your findings, I believe my truck has the same issue with the cable carrier contacting the rear sliding window. To be honest, I had pretty much given up on pursuing the issue. It wasn't until I recently drove another brand's pickup that I realized just how quiet their cabin was—and how noisy mine has been all along. On my truck, the rattle happens on almost any paved road, gets even worse on rougher pavement, and I can even hear it during braking and acceleration.   I actually referenced your thread when submitting my case to GM, hoping they'll recognize this as a recurring issue instead of treating it as an isolated incident. The reason I reached out to GM first is because my dealership told me they would need to keep the truck for at least two days just to diagnose the problem. I was concerned that even after two days, they still might not be able to identify the source of the rattle before giving the truck back to me. I had also asked a few dealerships about this issue during previous service visits, but none of them seemed to know what was causing it or had a solution. That's why I decided to contact GM directly first, hoping they might already have an official repair procedure or guidance for this issue.   I also hope GM eventually comes up with an official fix for this problem. I have a feeling there are many Silverado owners experiencing the same rattle, but most either choose to live with it or simply don't know what the cause is.   Really appreciate you taking the time to document your diagnosis. Your post is still making a difference years later.

      Do you have access to BP fuels? Some stations have Silver 91 E-0 priced the same as their 93 E-10.  There is a local Marathon with 90 alky free for $6 a gallon but I go down the road to BP for $5-ish. They also have a 100 E-0 but that stuff is $10 a pop.
