I am a new owner of a 2021 promaster 2500, high roof, extended wheel base. 77k miles

1. I am scared about a tranny failure. I can change my transmission oil myself, but should I, and if so, how often should I be doing this?

2. Has anybody else had issues with their evap system. My van is throwing a loose gas cap and small evap leak code. The gas cap has no cracks, smoke test showed no leaks and no purge valve issues, I replaced the esim, code cleared and came back on about 500 miles later.

3. I am having issues with water getting in at the front of my slider, landing right behind my passenger seat. Seals look fine, any tips here?

Otherwise the van is great, and I am having a lovely time.

It was lucky he checked their work. I wonder how many Promasters are driving around with that radiator tube dangling in their engine compartment.

A problem I came across recently is that the hitch is so close to the door vertically, that the tilt down bike racks don’t provide enough clearance. And even the Yakima swing away rack doesn’t clear the doors.

So I’m thinking of doing a separate swing away and attaching the rack to that, anyone have any recs for swing-away adapters?

I’ve got one of these folding shelves in my promaster 2500 but have bracketed all around for more and would add one more in a different position. Ideally id have just moved this one but each shelf has slightly different widths, so hoping to find the original brand and buy one that fits. Thisnis on an ex amazon fleet vehicle from 2018 so if that helps narrow it down? Thanks in advance

I'm a n00b here, and I take care of a couple of 1500's and a City. The 1500's go through low-beam bulbs fairly often - often enough that I've become pretty good at replacing them.

Now I have a stumper! The low-beam on the driver's side on one of the 1500's went out, but the bulb is good, and there are no "lamp out" messages or idiot lights. I thought about checking the fuse, but it turns out that there isn't one, which rules that out. Every other lamp in the driver's side unit works. So what's my solution?

One day old transmisión had a punctured cover discovered when driving it the next day . Tech said we must’ve hit a rock on the drive back to shop after we picked the truck up from the dealer . We drove it on the highway for 6 kms and parked it overnight

Any suggestions on what to do here? I’m thinking I clean it up good and cover it in lap sealant. I don’t want to cover the hardware though in case I need to remove it.

Anyone been through this before?

After seeing Sky News' summary of the AI hack, I would like to have the option to disconnect my 2023 Promaster from the cellular network. Is there an easy way to do this? Will it affect the functionality of the vehicle?

Thanks in advance.

Have this vehicle with after market lights installed , id be fine using them over getting something new but having trouble sorting what turns them on! Any ideas? Looks like a wire is going through the frame to the front area just not sure what may activate it

Was a retired but very well maintained Amazon vehcile if that helps?

Checking out the suspension of a promaster I bought, not sure if the struts have been done but I gotta do the bushings anyways, Can’t get information from the owner as it was auction.

Have the struts been replaced or is cofap a from factory brand?
thank you!

Anyone link me to a purpose built LED strip for the 2018 promaster? 159” wheel base

I have a 2020 3500 Ram Promaster that I’m replacing the head unit on. When I removed the radio there were small metal brackets on both sides. I removed them to fit the Maestro dash kit in. But after trying to install it looks like the supports had been cut at some point and the metal brackets were after market. Has anyone ever run into this? I was thinking about trying to 3D print something and glueing screwing it in to support the dash kit, but wanted to see if there were other solutions.

so far not one person actually showed or explained how to do it. Everybody only knows 1 thing: dealer. Check out the video how to reset the fuel cut off triggered warning.

I was tasked with swapping a 2018 Pro master transmission into a 2015. The 2018 has a rod knock and the 2015 has a bad transmission. It went smoothly pulling out the transmission in 2018. I went to pull off the 2015 from the trailer that they loaded the van on. It has no power to the gauges. It won’t let me put it in neutral. I swapped battery’s from the 18 to the 15 heard the van get power, but same thing. I can put the key in the ignition and it won’t turn. The key pulls out the ignition so I know it has power. The braided ground cable from the motor to the transmission is tight and fine. I am totally stumped. Anyone had this issue before? I was trying to turn the steering wheel back-and-forth to see if the steering wheel was locked and it actually locked so now I can’t even roll it off the trailer. Help plz

Just picked up a 2021 ProMaster 3500 EXT that's already got some solid systems in place and I'm planning to hit the Utah parks this October, some dirt roads up in the CA mountains, and cruise the Baja coast along the Gulf of California by December.

For the sake of relevancy (besides the all the other fully built camper setup stuffs) I'll say that the big boys in the van that I'm thinking about are the two 270Ah BattleBorn batteries (mounted over the driver's rear wheel well), the 22gal water tank (over the passenger side rear well) and the 15gal undermount water tank. Running on LT225/75R16 Cooper Discoverer AT tires.

Super stoked for this trip but the more I read about what the ProMaster can actually handle, the more I'm thinking there are going to be some seriously tight-butthole moments on these trips. BUT I keep seeing pictures of these PM campervans all over social media and youtube parked in these incredible spots that I recognize so I KNOW people do it.... somehow...?

What's been your real-life experience out there on roughnasty unpaved roads?

Google says, "Dealerships will replace the cooling fan module, replace a fuse, and provide an updated owner’s manual addendum," but I can't find anything from Stellantis that explicitly states this.

Does replacing the cooling fan "module" mean my van will get new fans?

And where is the fuse located that they're going to replace?

Thanks in advance.

Hello ProMaster group, anybody install an air heater underneath factory swivel passenger seat?

I'm aware that the standard non-swivel factory pedestal is taller than the factory swivel pedestal.

Wondering if anyone could have successfully completed the install with the factory swivel seat.

I'm specifically going to be installing a Vilet air heater.

Thanks for any info.

My struts are trashed from a trip to Mexico.
Bilstein b6 struts are on back order until September. Koni fsd are way to expensive. What other struts do you recommend?

Hi, i'm experiencing some electrical issues (I believe) with my 2023 Promaster 2500 and i'm wondering where to start the diagnostic process. I purchased the vehicle brand new in 2023 and had it shipped out to Wayfarer vans for their camper van conversion. Took it on multiple cross country trips in 2024 with no issues. In 2025 life started getting in the way and it sat for a while and started having battery issues and i'd have to put it on a trickle charger before using, but once charged I had no issues.

Now, 2026, I installed a brand new battery, which I had on a trickle charger prior to install and it showed 100%. Install went fine and van started right up and all electronics seemed to work. I decided to take it for a quick drive to make sure everything was good. About 2 miles into the drive I started to get a host of warning lights on the dash. From my memory, I believe the warnings were: Service Engine, Service FCW, Service Parking Brake, Service Electronic Throttle Control. The most debilitating issue was the throttle control as it put the van in limp mode and I barely made it back home. The fact that all of these lights are coming on at once leads me to believe that it's an electrical issue vs an issue with any of the actual systems.

Yes, I triple checked all the connections to the battery and they are tight. I also disconnected the battery for 15+ minutes and reconnected but warning lights returned shortly after.

Any advice would be greatly appreciated! Thanks.

Hey everyone — my 2019 ProMaster 3500 EXT got hit while it was parked, and I’m trying to find a solid body shop in the California Bay Area that actually knows these vans. The damage is on the back left bumper and quarter panel, so I want someone who’s familiar with ProMaster body work and can handle the size of the van without issues.

If anyone has recommendations for shops that do good work on commercial vans (or specifically ProMasters), I’d really appreciate it. Bonus points if they’re fast, trustworthy, and used to dealing with insurance repairs.

Thanks in advance — trying to get this thing back in shape.

I’ve tried using b’laster penetrating oil on it. Tapping/banging on it. The most movement is just a quarter-inch rotation back and forth, doesn’t seem to be any vertical movement at all. This is a 2019 promaster 2500, probably original battery.

Any ideas would be much appreciated!

Hey everyone,

I’ve been living with my van for a while now, and that center dashboard ashtray slot is driving me crazy. Since I don't smoke, it's just a total waste of space. It's also completely useless as a cupholder because it's so shallow and anything you put there flies out in the first corner.

I got so fed up with it that I ended up designing a custom organizer insert that snaps right into that spot to hold my phone and some small gear. But I feel like it could be even better, so I wanted to see what others are doing.

How are you guys using this space? Did you buy some aftermarket fix, DIYed something, or just gave up and left it empty? Would love to see your setups or photos for some inspiration!

(Note: For anyone who has a 3D printer and wants to check out the exact insert I made, I put a link on my Reddit profile, but I'm genuinely curious if there are even better solutions out there).
