68RFE vs. AS69RC (AISIN)
So, what one is better? RevMax says Aisin is NFG, get a 68. Lots of premature wear. I am sure a stock 68 will handle what I need but have always heard the Aisin is a stout transmission. What is the real deal on these?

I don't know much about the Aisin, but I could see RevMax being a little biased.
I read over and over that it's not in the same category as the 5R110 or A1000 6spd when it comes to reliability.

I have read and read and read and read some more and still reading. Seems like some inferior hub material in the AS69RC, and no tuning for the AS69RC TCM. Called and talked to them (RevMax) and they said 68RFE is the way to go. They do offer a $8K performance AS69RC. Still unsure what way to go.

The Aisin is a stout tranny. Biggest current drawback is there is no tuning available for it.

Aisin is a lot better trans if you ask me, for stock applications.
I still fully believe that a 68rfe is a complete pile of chit.

Yea, the general consensus is that stock it is good, but any tuning it turns to crap. I would just want to delete the truck, seems like just doing that there could still be issues. I have seen a few 68RFEs last a good while. Why can't Chrysler/Dodge/Ram/Fiat (whatever it is called these days) figure out a transmission for these trucks. Ford and GM have had theirs locked down for quite a few years.

It baffles me... they haven't had an auto trans in their history that works well.

My 68RFE is at 335k miles and counting, at stock-ish power levels, for whatever that is worth.

We don't have any proof but my friend/boss has a 4th gen with 403k on it and it shows no sign of ever being out of the truck.

My situation is largely the same, I bought it used, but between what I see and the oasis report it looks to be original.

Ford and GM don't run theirs behind an L6 running on steroids. I think that has a lot to do with it.

With common rail you can tune the engine to act however you want between shifts. There is no excuse.

I am trying to figure out the one that is the less piece of chit it seems like.

It's hard to say really. In my opinion anyhow.
I've seen both last a long time, and I've seen both with problems.

I was just referring to the mechanical differences of V8 vs L6. The 5.9L and 6.7L Cummins are a lot harder on drive train components. One less power pulse per rotation, larger pistons, more torque lower in the rpm range, etc. I 've seen a couple 12v's (I know, not CR's. ..) bust up the Alison pretty nicely. Expensive unit to rebuild. I never much got into the Aisin or 68RFE yet but I just meant to say there's more to it than Dodge just can't make or get a decent trans.
We've got a local shop that can tune the 68RFE pretty decently. They tuned one up for a buddy of mine and he says he has no complaints. Regular tow machine on a 34' gooseneck. 150hp tune but only has around 100,000 kms on the new trans tuning though so reliability remains to be seen.

68RFE vs. AS69RC (AISIN)
Yes but I've seen some Ford stuff take nice power above stock and live to tell the tale.
Dodge can't say that. And their trans have always sucked.
Don't get me wrong, I'm not praising an Allison because I have never liked them and don't foresee my opinion changing.

I'm not saying I disagree that on average the 5r's and A1000's hold more power longer, and seem to shift firmer, but saying that all dodge transmissions suck is pretty broad. At stock power levels, I've seen all auto manufacture transmissions last, and with a tuner, I've seen them all fail.
The new Hemi 1500 8-speed transmission transformed that truck. The 48re help stock power just fine, and just by cranking the line pressure can hold up to a tuner pretty well.

As a dealer we see a large amount more of 68rfe failures compared to the aisin. We're probably into a 68 4-5 times a month. We've been into a aisin once in 4 years. I don't really think the 68 should be behind a cummins. Alot of the internal parts of a 68rfe are the same as the 45rfe that was used in dakota's and grand-cherokee's. Just not heavy enough. Stock and not beat there ok, but if you get the slight bit silly with the throttle there done.

Just for the sake of data, you said you replace ~216 times more 68rfe's than Aisins. How many more 68rfe's do you sell than Aisins?
