Yeah, the 2008 Honda Odyssey backup family wagon actually does pretty well.

It's funny, I actually like driving it. It's a bit easier to zip in and out of places and park. If not for towing my 5th wheel there's no way I'd drive an HD truck daily. Our 3rd vehicle is a Hyundai Tucson SUV that my wife mostly drives. When I walk out to the garage for a quick store run I just automatically grab the minivan keys. Even though it's the oldest and least glamorous vehicle of the 3 it's just super easy to drive, easy to load groceries into and easy to get in/out of. I just can't find anywhere to mount the 5th wheel hitch

It goes a little something like this:

Hmmm..... The Odyssey does have a sunroof!

Well, I'm hoping this is the conclusion of "failed tranny 2.0" - My dealer was nice enough to lean on the regional manager and get a new valve body expedited. I got my truck back tonight and it feels great. I didn't realize how bad the last rebuild felt until I drove it this time. Frim, crisp shifts and it feels good.

I'm not sure how/why the valve body tested okay and wasn't replaced when they were rebuilding it +/- 100 miles ago but it is what it is. Granted, it's only about 20 miles home from the dealer but I got a good chance to get her warmed up and run through various shift sequences up and down and all felt great.

Still trying to be, "glass is half full" guy - I didn't miss any RV time and didn't get stuck anywhere. Just hoping I can retire the minivan to grocery runs.

My truck just popped up the P0871 code. We’ll see what the issue is, but it has already gone into limp mode (1st and 4th Gear only) but it would reset and drive normal after I shut off the truck and start it back up. Hopefully the lifetime warranty will cover any repairs. But I’m not holding my breath on that.

OP here - This thread just popped up and it's funny for me to re-read where I was at just two years ago. Since I posted, the 2nd rebuild has worked well.... as in, the truck hasn't stopped moving. The tranny still shudders/shakes at times and if not for my lifetime warranty I'd likely unload the truck but it is what it is.

The previously discussed Honda Odyssey has been floated over to my new home on Maui and is serving me quite well. I'm getting my home inspection business here on the island up and running and driving the trusted Honda daily. I still maintain somewhat of a residence on the mainland and my Ram sits with my 5th wheel at a relative's house and I live in it when I'm on the mainland (usually a week every month or so). I'm torn as to whether or not to bring the Ram over the Maui or just buy something here. With gas prices and world events it looks like I'll be driving a scooter around so I guess we'll just have to wait and see.

This thread kind of reminds me what happen to a friend's F150. Had a bunch of transmission issues. The replaced or fixed the trans multiple times, but warranty never replaced the torque converter. On the third try, they finally replaced the torque converter and he never had an issue again.

MN-Ram · Mar 14, 2022

My transmission started slipping last week as well. The dealership expects to dig into my transmission tomorrow. I hope they can fix it on the first try as well (ideally by just installing a new transmission) but we’ll just have to see.

The service advisor said my transmission needs a new valve body and that a valve is sticking. I do wonder why a valve body would go bad as well as what would cause a valve to stick though. Could it be clutch/band material?

I got the same dreaded P0871 code on my 68RFE. Replaced valve body with one from Revmax and all was good... that was until the OD clutches decided to give out and get burned up. Replaced with a Randy Stage 2 Extreme and never looking back. Anything with RFE from the factory is practically trash IMO.

Th dealership got back to me and said it is under warranty. They will do their thing. I guess the tech is going to do a little more digging to try to find out what caused the valve to stick.

The VB is absolutely **** from the factory. Thin sealing plate, barely sufficient accumulator plate, etc. You have to look at the comparisons on YT or whatever and you will immediately see how much RAM skimped out on it. Glad your repair is under warranty though.

I just picked up my truck this afternoon. It’s sluggish, but it is shifting ok. I know it’s still in learning mode from the rebuild. We’ll see how it performs over the next couple weeks.

Just had the valve body replaced on my 2018 3500 (44K miles) with the 6.4l hemi. Didn't have any major issues prior but when towing my camper (6kish lbs) I would get weird downshifts from 5th to 4th and then eventually would go into limp mode with no check engine light on. Would go back to normal after a restart of engine. Got the code for transmission shift solenoid not too long after.

Replaced valve body under warranty and not sure if it's placebo effect but my truck seemed to shift sooooooo much better driving on the way home. It was like butter going up and down the gears. Looking to take the camper out in a few weeks so will see what happens under load since that's why I got this truck. Since the valve body was replaced I'm hoping this will be the end of the issues for many years and I got a good one that won't break down again.

I was back into the dealership today with all sorts of fun codes tripping the check engine light. Improper gear ratio: 5th gear, Improper gear ratio: 6th gear, and something about the wrong line pressure. I just had the line pressure sensor changed last week.

The service department said my tranny is toast. Now working through the lifetime warranty company to see if they will stand by their contract coverage.

Is this an FCA warranty? (does/did anyone else even offer a lifetime warranty?) If so, YOU shouldn't have to work through anything. That warranty is the same as factory. Unless you have a bunch of mods that could void it you should easily be covered.

The warranty is through a 3rd party warranty that the dealership buys when you buy a new vehicle them. So far the warranty has been good (it covered the valve body last month), but now some real dollars will need to be shelled out. So we’ll see how they really are.

Powertrain should be a pretty easy one I'd like to think. Especially if they just covered the VB it would seem to be hard for them to weasel out of coverage now. Good luck.... let us know how it goes!

You probably just need a new pump and overdrive clutch assembly, but hey if you get a free transmission it's all good.

Not being a debby downer here, but your VB issues are probably just the calm before the storm. My overdrive clutch housing only made it a little over a year before it went out after replacing VB with Revmax. Of course this isn't saying yours won't, but these transmissions barely hold themselves together... they really need to do away with both the 68RFE and AISIN and just get onboard with a single transmission like the competition that are built to withstand low end torque from the Cummins. ATS has a comparison video of the Allison vs the 68RFE and the just general difference in size of components is laughable. You can easily see why they just don't hold up.

I drive a one ton heavy duty truck and at the moment only tow a 6k lb camper so no where near a heavy load and I don’t drive it around like a madman. I’m not going to live in fear this truck that was built and designed to be a work truck with heavy duty components is going to fall apart.

To say these transmissions “barely hold themselves together“ is just laughable to me. People much smarter than you or I engineer and build them to do their job and in my case a heavy duty work truck. You can take your negativity elsewhere.
