Is the Aisin transmission worth it?

I'm sure the 68RE is an adequate transmission, as is the Aisin. There are those that preach the "MDT" moniker for the Aisin but that usually devolves into semantics. Bottom line is that they are all (regardless of brand) fairly decent transmissions that none of us will be able to quantify their strengths or weaknesses.

So the Aisin is not a MDT trans? Please elaborate.

I put my money where my mouth is and spent the extra for the Aisin, I'm an SRW but been right up to 25k GCWR and at that weight I like to know I have a trans with 140 lbs for metal in it than the 68RFE. For the DRW guys towing at near 40k, it's cheap insurance and a no brainer.

Now, people who tune their trucks is a different matter....they should've bought a Mustang

Feel free to put whatever acronym or label on your transmission you like. If the Aisin is a MDT transmission, cite what MDT utilizes the AS69RC.

I opted for the Aisin simply because it allowed for greater hp/ torque and I did not like the 68RFE in my '12 Ram.

One MDT is the 45 and 55 series Rams. BUT, not sure of any others.

As you Rick notes, ALL the current transmissions in the pickup lineup are way the heck better than 30 years ago, even 10-15 years ago. Take your pick, do not look back.

With this in mind tho, I personally would take the aisin, only because as I stated earlier, the first gear is lower, so you have more take off gearing etc for low speed maneuvering. The difference in OD and DOD is not enough to worry about. But stalling out on a steep grade can be an issue loaded heavy enough.

I have not towed the new MS but I did tow the 07 MS twice with the 15 RAM with Aisin. It really gets 30K rolling easily compared to my 11RAM with 68RFE. To be fair the 11 had 3:42's. Still I know there is a big difference with the Aisin.

One thing that really impressed my was I took Conway Hill about a 5% grade on I-5 NW WA on cruise at 60 about 1/2 way up the trans downshifted to 5th without dropping 2-3 mph before downshifting like the 68RFE would. I was surprised it downshifted so seamlessly.

What your truck does is how I tow with our truck but I hit the button for a downshift because the Allison and duramax seems to want to keep pulling in high gear and of course lose some speed.

Right now it's a coin toss between two trucks I have located. The salesmen from two different dealerships are gonna have to start competing when I call them Monday.

The ram dealer located a beautiful white Laramie Limited CC LB DRW with Aisin, 3.73's and hitch prep.

The Ford dealer has a black platinum CC LB DRW with 3.73's and hitch prep.

Game time!
