Aisin transmission Problem

[Dave90]

Just wondering if anyone else has this problem.

I have a 2016 Ram 3500 with the Aisin transmission bought it new.

This just started about 2-3 months ago.
When i let the truck set for 2 weeks or more it will not move when i put it in gear, forward or reverse, for about 5-10 seconds.
I think it's the fluid draining out of the torque converter.

Before this started a few months ago it has sat for a few months and it worked fine.

I had some recalls so i took it into Dodge, after 3 weeks i called and they said it was done, i asked what they did to fix it and was told about fixing the recalls.
I asked about the transmission and they said that was normal operation. Every vehicle will do it.
It's funny they didn't mention it when i dropped it off since every vehicle will do it.

No other vehicle i have owned has done this.

Does anybody have an Aisin that does this also?

Dave,
My brother has an Aisin and does not have that delay. Not sure about the Aisin but most trannys have a valve in the line that prevents the oil from draining out. It could be that valve is faulty. Just a thought.

 

[Dave90]

Thanks, just trying to see if anybody else has heard of this or not. If not i'm going to get with another dealer or get ahold of Dodge directly to see what i can do.

 

[Dave90]

No one else has seen this?

Haven't had it with my Aisin, but my '05 with48RE would do that now and again.

Once you realize every dealer is full of ****, this wont hurt your feelings so bad. People should rethink letting dealers ever touch their cars for tsb's, some are good some are bad, really really bad that will ruin your truck. I don't know anything about the Cummins recalls, I would look into what they did. So it's a little unclear, you got the recalls and it has been f'd since? or it didn't go that way?

 

[Burla]

If not for recall issue, first thing I'd look at is line pressures and upgrades that can help that.

 

[Dave90]

The tranny problem started a few month ago, separate from the recalls.

 

[Burla]

well I would ask the full of **** dealer wtf they are talking about since it didn't happen since 2015 til 2019. Cummins you still have warranty left? At least get the refusal to accept the warranty work on paper, what ever that process takes, in case it isn't fixable without serious measures. There is so much out there on the rfe, if it was the rfe there are like twenty guys here that can give you a perfect plan to address the valve body and then move on from there. My sense would be there is some of the same fixes for your transmision that don't exist yet for the new 8 speeds, but because the problems are more rare, the answer will be less prevelant at ram forum. I would also search tdr, you will have a larger group of guys running that transmision for long miles and heavy work that will have a large pool of issues that can help you if you don't get the answers here.

How long is it running before you try to put it in gear? I’m assuming your not starting it up and slamming it into gear right away. I see this sometimes with vehicles on the lot after they’ve sat for awhile, but by awhile I mean at least a few weeks, and it doesn’t take 5-10 seconds before it’ll move.

They do have valves to prevent the torque converter from draining over time. Even then they will drain some but it shouldn’t completely drain it to the point it can take 5-10 seconds before it will move.

There’s no recalls for your truck that would have caused that issue. Try another dealer maybe.

 

[Dave90]

Thanks for the info,
Up until a few months ago i could start it even after 3-4 weeks of sitting, put it in gear right after starting it and would move like normal.
Now i would say after 2 weeks every time I start it and put it in gear, at idle it doesn't move for 5-10 seconds.
Ram dealership technicians said this is normal, just don't understand why it would start doing it after 3 years, bought it new, and if it's normal why the service advisors didn't know it right away when i dropped it off.

 

[Tach_tech]

Have you checked the fluid level? How long do you let it run before placing it in gear?

I filled out a report with customer cares.
They had me take itto a second place left it for t2 weeks and got a diagnosis.

After waiting 2 weeks i picked up my truck and looked at their diagnoses which didn't show anything.

I asked the service advisor about what they found because you can't tell anything by this, nothing hooked up to it, no pressures no nothing.
I asked did it do anything at all, he stated the technician said it did what I said for about 3-5 seconds. So I said why doesn't the report stated that, he said he was told by the service manager to write down, it operated as designed at this time, nothing more.
I asked the service advisor where anything shows in writing that that is normal, he couldn't and said to show him anything in writing that it's not.
I'm glad I didn't pay for the diagnosis.

All they said is I have more warranty to not worry about it.

I'll bet if they paid over 70K for a vehicle they wouldn't like it.

Now i'm waiting for the Customer cares rep to find something in writing, been 2 days nothing yet.

It's funny how Dodge doesn't want to fix things.

Have a vibration in it at 40 mph and 70-75, was told mine isn't as bad as others they all do it.
About half the time , the door lock button on outside handle i have to push 4-5 times to lock they can't find anything wrong.
Now this with the transmission.

I think when i trade it in i'm going to be looking at chevy also, not against Dodge but gonna open up GM as a possibility.

If Dodge ends up doing anything i will keep this post updated.

I don't blame you for being pissed, but if you think the phony Allison is any better think again. The only vehicle I have Lemon Lawed was a Chevy with an Allison that GM refused to fix.

I usually start the vehicle, no matter what it is and throw it in neutral first. This engages the trans pump. I let it idle like this for about 5 seconds just to make sure everything gets oil. You might try this. Its cheaper than a trans repair.

 

[Rlaman]

Correct me if Im wrong but I believe the Aisin is the 6 speed. Who makes the 8 speed ?

 

[caulk04]

The 8spd is a ZF design, manufactured by Chrysler (or whatever now) under license.

Fluid drainback was a very common issue in the 45/545/65RFE and likely the 66/68RFE as well, though I have no experience with those. The cooler return filter was the culprit.

Many transmissions don't flow fluid through the cooler in park, so the best bet is to run the truck in neutral briefly to refill any emptied circuits. This will cause no harm.

Has the trans been serviced recently? Is it past due? I thought I read in a maintenance schedule once that the Aisin has a pretty short service interval.

 

[Sandevino]

The ZF 8 speed is manufactured by ZF. This transmission is damn near bulletproof if properly maintained to ZF’s requirements.
