Good news for you Ford and Dodge guys

Yes there have been adapter kits and stand alone TCM available for a while. Expensive endeavor though.
Especially considering virtually every Dmax iteration is comparable or better than the other 2 except in small circles, like long haul hot shot drivers. Cummins gets the nod for engine life there.....theoretically.

AISIN Medium Duty trans in my truck already and it's a more capable trans than the current Allison the the pickups.


Allison behind a Cummins is nothing new as prior to 17 that was an option on the F650 and 750's. But that was a more HD trans than what's in the current GM pickups.

I haven’t seen transmission failures as being any significant problem. Not worth the money and effort as any kind of preventative measure. Maybe as a replacement for a failed one.

It's nothing new. Kits have been out there for years. Totally un-needed. And, a colossal waste of money. The HD trannies in the Dodges and Fords are just as good as the Allison, and better integrated into the vehicle electronics too.

In 2001, the allison was a big step up from the Ford and Dodge transmission options. However, when GM raised the bar IMHO it didn't take long for Dodge and Ford to come up with transmissions on par with the Allison.

One can argue forever which is better, but again IMHO all three have had very capable and reliable transmissions for the last 5 maybe 10 years.

And for earlier trucks, I suspect it is way less expensive to have the factory Dodge or Ford transmission rebuilt by someone who really knows the transmissions and builds it for towing than springing for an Allison conversion.

Totally unnecessary and would be a big waste of money.
I had zero issues or problems with my Ford transmissions. Current have a 2011 F250 diesel, had a 1991 f150 with a 302 V8 for years, our son currently has a 2015 F150. No transmission issues.
When I had a 2007 Monaco class A coach I did have a problem with the Allison transmission it had, it would not shift into Drive, and left us stranded in a parking lot once, it ended up being the electrical plug got moisture in it.

I have had Ford and Allison. I like the Ford better. In my opinion it shifts and down shifts better. No experience with the Aisin.

Don't have any experience with the Dodge Aisin but have several Fords with the torque shift and complete satisfied with their performance. I don't see it as a upgrade.

Took Ford 5-10 years and ALLISON still has far better Quality Control.

Did you know Allisons are tested to beyond -40 on the cold end and over 120 on the hot end? (ambient temp) One of my friends help build and test one of the cold rooms used.

OK so I am personally involved in said testing for one of those non-Allison companies and I can assure you they are all tested to these levels (or beyond) regardless of manufacturer.
