Aisin Max Tow Programming C&Cs and P/Us

[Cummins12V98]

I paid under 1,800 for 5er/gooseneck prep, rear air and 4.10's. I'm betting the cost of the hitch is around $1,300. $276 for the cargo camera. Brake controller was included in the LongHorn.

 

[Cummins12V98]

Perhaps I missed it, but while the reverse is true, where does it say you get Max Tow by selecting 4.10s, and/or gooseneck prep? Not to speak for Wiredawg, but that seems to be the root of the question, "is there a programming/operational difference with Max Tow?".

Prep has nothing to do with it. 4.10's is MAX TOW. There are other things like air ride etc that can go along with it.

He was asking about the pickups, he knows about the 4500-5500's

That isn't the way I read the first post.

But either way his 09 was a 4500 which has a AS68RC and he also had a 17 5500. But did ask the following:
So pickups and C&Cs that don't have the max tow, do you have 6th locked out or not?

Which could indicate either.

Your quote of my quote of his quote was post number 6. I did answer HIS question.

JR,

My bad...even though my thread is primarily Aisin, I would like feedback on the 68RFE too. I'll be sure to be more clear. Thanks for the input.

Can't remember where I found it, but the AS68RC max tq was rated at 730 lb ft, but I was running around 800 lb ft on it... proves to me it was well built. I could not find the max tq rating on my AS69RC but theorize with the 930 tq HO Cummins, it actually must be at least 1000 lb ft or higher.

I imagine the 5th gen Aisin will have upgraded internals, programming, and maybe gearing. Maybe 1080 (WAG)?

It was more of a failure in reading comprehension on my part, you had mentioned 68rfe in the opening post and when lpennock made a statement on the"68" I ASSumed he was referencing the rfe. But after re reading his post it was obvious he wasn't.

On the subject of GN hitches I'm a pretty big fan of B&W. With their GN plate I can run a GN or a 5th wheel off of that one hole in the bed rather than one for the GN and 4 for the factory puck set up. Their companion hitches are good quality.

 

[Cummins12V98]

B&W is TOP quality. BUT you are limited to 20k towing with the gooseneck connected companion. The RVK3600 is 25k with 6,500# pin.

Best way to go is the 4 puck and GN connection as it's a CHEAP option. Besides you need the pucks for the safety chains with the gooseneck.

 

[JR]

Best way for some but not all. Not everyone wants a 40 ft land yacht that is restricted from more campsites than they are allowed in

Friends, right now it seems the biggest missing information is: is there any difference in Aisin programming between Max Tow Pkg equipped trucks and non-Max Tow equipped trucks? Or is it just additional options grouped into a "pkg"?

I've never seen anything that indicates any difference in the programming. The brochures only talk about a HO motor with the Aisin or a non-ho with the 68re. I have to believe it doesn't as my 3500 just had the prep group and it is rated at the same 30K as the max tow with the caveat that I need to have the correct 5th wheel hitch.

 

[Wiredawg]

Ipennock,
That sounds logical to me. I'm real happy with the results of this thread. Let's see what next?
Ron

 

[TFucili]

I knew I had seen it somewhere, and it is on the "Build & Price" for C&C. When you click the "Info" tab under Max Tow you get this:

So does that not indicate the Max Tow gets different calibration, at least for the C&C???

 

[Wiredawg]

TFucili,
Bingo! I thought I had read to. The programming is amazing on this truck. So that was where I found it back when i was looking at buying my 2017 5500.

Thanks, Ron

They must have dropped the rating on the B&W Companion. Mine is rated at 22KLbs and 5500 lbs pin weight. See the specs on mine.

Ron

 

[Cummins12V98]

Your spec shows a model 3050. Big difference compared to the RVK3600.

Good catch: I didn't realize B&W had different rated Companion hitches. You know I'm big on capacity ratings, thought mine was 20KLb, putting me over. I purchased it in 2009 and had not looked at the rating since then. I'm glad I'm on the happy side of that number.

Cheers, Ron

Friends,

Just thought I would add a little tidbit I checked the other day: On the Aisin in my 2017 5500, gears 4, 5, & 6 has TC lock in normal mode and in TH, 3rd also locks up. 1st and 2nd do not lock up on my truck in either mode.

Also, while I had truck in TH with EB on (never turn EB off) it brought to mind why I don't keep my truck in TH because of very aggressive characteristics. I'm talking making me lunge hard into my seatbelt. Maybe its my 4.88s that cause such strong function, but it is very uncomfortable. But with a heavy load, it is amazing.

Anyhoo, just thought I would share my further observations on this topic.

Cheers, Ron

 

[Cummins12V98]

Second should lockup.

 

[Wiredawg]

Second should lockup.

Ron,

According to the Edge CTS2, neither mode showed lockup in 1 and 2 while accelerating. I didn't think to check decelerating. Next time I take it out, I'll check while decelerating.

EDIT: Just checked a data log I ran with CST2 and definitely no lockup of 2nd or 3rd with TH off.

Cheers, Ron

Mine won't lock in 2nd while accelerating under normal driving or towing, but it will lock in 2nd with extended operation in 2nd which often means locking out all gears above 2nd. I have seen it lock in 2nd without locking out 3-6, but not as easily.

For me 3rd lockup is common, and fairly frequent. I do suspect that you spend a lot less time in 3rd than I do with your 4.88's thou.

Copy that. I need to run the logger while operating normally... I ran it doing rapid acceleration and didn't run it in TH. You're correct, mine shifts very fast with the 4.88s. For the most part, a lot of this is FYI... not having problems, just wanting to understand how it operates.

Thanks for the input.

Cheers, Ron
