Aisin Transmission Poor Quality OMG did I make a mistake if correct

[gsbrockman]

Might as well post up another pic of a fake / un-real load.....
Trailers weighed in at 22,900 lbs per the MSO’s....total GCW was 33,760.
Since this thread is about the AS69RC.....I’ll add I have really enjoyed my two previous AS69RC’s and am enjoying my 3rd one immensely!!!!!!

Greg do You remember all to rhetoric back in 2013 on the Aisin? I even remember the one's in 2008 on the 68... and My guest the 2020 will be the same 69 as Now.

If You want to complain go Buy a Ecodiesel your chances are pretty High you will get a zero Build , Although the ZF 8HP70 Awesome the 3.0 O No ,will give plenty to fuss about.

Yeah.....”the nightmare of a transmission” as deemed by some transmission builder.

It was hilarious that during their “tear down” thread they already had it diagnosed with Stage IV cancer before they even removed the first nut off the case......

The Aisin is the poster trans for Fear factor at the FBI (Fear Built Inventers) turn up by Internet amplified worries gang.

A weak Aisin? LOL. The guys that deliver to our job sites have not broken an Aisin yet. I usually talk with them about trucks and have seen some photos of huge loads. One image was of a gooseneck with two backhoes being pulled by a 3500. I think my Aisin will be ok.

I had an aisin rep call. He stated that it would be hard for him to agree increasing power a little with tuner would cause failure. There service units or ones they track that fail under warranty are almost non existent. The parts come from Japan to maintain quality.

We talked for sometime. In the end I felt comfortable that it is crazy to think that running in tow mode on a tuner is going to bust this thing. I think driving it up the 10k passes in CO with trailer were much harder than a little more power to get a tune that eliminates lag with an empty truck

brllmtb , Revy Just spouting off about the 69, I like him, But he's wrong about this, Its NO different then Bill Kondolay 2004 claim that all 48re were going to fail because of the bad thrush washer..... If you want to rid yourself of the lag, Mod the rail, it has internal fuel restrictors that must be removed, 1000s of 6.7 owners of done this .

My 6.7 has NO lag or dead pedal , its around 440 RWHP form Feb of 2014 to date on a stock 69.

I called and talked to the RD of Aisin MI Back in 2013, He clearly set the bar on the 69 425-440- 1200 FT TQ for life normal use towing,

The 69 is clearly more robust then the 68rfe by visual inspection and the way the 69 transmits power is superior to the 68rfe.

The majority of the lag Is the design of the 6.7 Rail. Yes We Mod Rails... So I'm No different than Revy

When You Mod the Rail Owners will Tell You even the tone of the Motor changes at idle form the Mod.

I am curious that a rail issue when the engineer said it was programming

The problem isnt power. It’s how the torque management is altered. Tell us about this Aisin rep that calls retail customers.

Mod the rail and than report back what source was correct.

The restrictors stop the spikes but in the Process it created much of the lag, I suppose the source was unaware or just left that out.

Rolling into the throttle vs. pushing it down and waiting for the engine to catch up is a classic trucker trick that's been around for at least as long as road-speed governors. Maybe longer.

For what it's worth, the Ferraris with the DCTs -- flappy paddle gearboxes that can operate in fully automatic or flappy paddle mode -- exhibit very similar characteristics when operated in fully automatic mode.

If you just stomp on the gas the car kinda lags for a lllllllloooooonnnnnnngggggg time. It's torque management, and Ferrari tells people to deal with it.

So this isn't an abnormal deal here.

 

[brillmtb]

So the first person that mentioned it was TQ management programming was an engineer my dealer called. I even recall a percentage line 69% or something’s ng like that quoted

The aisin rep was in CA and after I posted the aftermarket transmission claims and asked for clarification on their site that apparently went to FL they contacted him to contact me. I told him I was shocked someone even cares to call me back.

As far as this rolling on the throttle that is definelty not it. You can even make it worse by coming off then back on. To roll it slow enough to prevent all perception of lag would mean situations where you had better not cross fours lanes of traffic withou a LOT of room. My 03 was way better crossIng traffic and entering a busy freeway

No, I don’t need a 4500 to do the same. I bought the 4500 as the 3500 was depreciated out and I figured I’d try something different.

Since we’re now ****ing and moaning, my front axle is rated at 7,000 lbs and my rear axle is rated at 12,000 lbs. GVWR is 16,500

What’s your truck numbers again?

Maybe you should start haulin sum real loads!

I guess I now need to post my 35k ticket.

I was always aware that a person might need to be taught how to "drive a manual transmission." Especially when starting from a stop or needing to speed up quickly.

Over the past 5 years, I have also learned that the Aisin auto is such a complicated transmission, that you have to be taught how to "drive an automatic".

For example, I'm sure I would need to get some practice "rolling into the throttle" as I got used to how different inputs deliver different acceleration behavior. And knowing or learning which speeds it might hesitate before delivering power.

And I wouldn't know the first thing about "locking it out of 6th"

My buddy who owned a 12 valve about 8 years ago laughs at my "drive by wire" Ram and reminds me that he drove his truck to the dealer with a blown computer. I guess back then injection timing was mechanical?

"Over the past 5 years, I have also learned that the Aisin auto is such a complicated transmission"

NEVER an issue with mine!

Looks like your truck over its' GVW of 14,000. Unless I'm adding up the numbers incorrectly, 5640 + 9880 = 15,520 which would put it over by 1,520 lbs.

Yeppppppppp.....it’s nice to see someone else besides me notice that, hence my post immediately after his scale ticket picture. If he were running commercially it would = OOS.

Come on you know that 14K is ONBLY there to keep the truck in Class 3 for insurance and licensing purposes.

If you disagree as I know you should not being a trucker. How can I have a SAE rated 9,750 RAWR and not load a pound to my front axle and NOT be overloaded???

Yes, it was.

At least give it a fair amount of seat time (after it arrives) before you jump to conclusions that it NEEDS more power.
Just today I towed a gooseneck stack of trailers to Mt. Orab, OH.....trailers weighed in at 18,540 lbs....total GCW was about 29,540 lbs.

Oh definitely! Any manufacturing "bugs" should easily be detected in the first few months of use, which is what a warranty is actually meant for. I will not tinker with it for a while. I just want to go ahead and get a tuner and delete kit while I can and have it ready.

No, I don’t need a 4500 to do the same. I bought the 4500 as the 3500 was depreciated out and I figured I’d try something different.

I am doing the same. Plus I like overkill. Bigger brakes, bigger frame, heavier suspension and better wheels/tires. I still have the 1996 and 2003 3500s, so what does it hurt to add a 4500, huh?
