Question 13-15 With Aisin Trans

[Jared Herzog]

I have a DRW with Aisin and 3.42. I have grown to really like that gearing. I can lock out both over drives and run in fourth if needed and it is just under 2000 rpm at 60 which works well for my area of Hill Country in Texas. If i ordered a truck today it would surely have the 3.42. And, the lower gears of the Aisin in first and second do work better. My 14 68fre had a bit more trouble starting out. But, that trans failed twice before 15,000 so there may have been other issues that made starting out not work well. And when i am not towing i can fly down the road at 80-95 depending on the road and limit and the truck is turning low rpms still. We do have areas around here where the limit is 85 and at 95 i am in the slow lane trying to just stay out of everyones way as they tear past me.

I don't have a source. Bob4x4 has confirmed that g56 torque management is based on mph. I am speculating based on my real world driving experience. I do know that unloaded acceleration from 45-70 is as fast as acceleration from 20-45. And I believe that it is because torque management is released somewhere between 40-45 mph.

It is speculation. But I can be confident that with a g56, you are not getting 660 ft lbs anywhere below 40 mph. I would like to put it onba dyno to confirm or debunk my observations,

I notice that the title of this thread states 13-15 Aisin. So I see that the OP is going Aisin. I would like to contribute to his inquiry that the 2013 model has dual radiators. Not sure if they kept that for the 2014 (I think they did). But I've heard they dropped it in 2015.

2013 3500 Had Dual Radiators, 2013 2500 Did NOT, MY 2014 3500 had D-Radiators Don't know about 2014 2500, 2015 Ram did away with D-Radiators in all trucks.

2013 2013 2500 Did NOT,

I beg to differ




My 2013 2500 HAS dual radiators. I'll post pictures to prove it when it stops raining out there.
Ironically, my detuned g56 version probably needs the dual radiators the least. But it has them. And the y connector that feeds them

Does your 2013 Have the 2003-13 5.9 /6.7 2500 Suspension , Front Axle and Frame ? If you don't know if its a ***** to get to the oil filter its a 14. if old style its 2003-13. Another Way to tell D-Radiators is the spilt Top hose. the 2014 Got the New 2500 Suspension and the dropped CAC/IC below the front bumper. I don't see how D-radiators would fit wit h the CAC/IC in front of 2 Radiators, one of the reasons they dropped the CAC/IC.

Mine has the old frame and old suspension.

But it does have the split "Y" hose and dual radiators. They advertised the dual radiators on both 2013 2500 & 2013 3500.

And they delivered on that advertisement.
I do not have the front axle disconnect, either

Post a picture of the Split Radiator hose on the front of the motor, They also advertised the new frame for 2013 2500 that was incorrect and the Air for 3500 in 2013. In fact 2013 Air was scratched and replace with the Air assist we now have.

This is what you are asking for?
