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.

After 20 years of using the Cummins and watching it eat autos, they designed the 68 from scratch and gained virtually nothing. The Allison works very well for a duramax and the 6r works great for Ford, while the 68 doesn't work well anywhere. They feel confused and mushy and won't survive anything over stock power levels.

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.

This is pretty much the line of thought I subscribe to.

They both suck, the 68RFE can suck a lot less. Without tuning in the AISIN you can throw all the parts you want inside but without changing line pressure, lock up, etc... you're not much better off. I saw some stock AISIN's last a long time, but they seemed to come apart with any additional power.

Maybe, we honestly see very few aisin's. But the ones we do see are usually tow trucks or utility trucks. Also with the way ram warranty works 99% of the time they get rebuilt. With warranty we have to do a cost comparo versus replacement. Almost takes congressional approval to get them to replace an entire tranny.

My dodge transmission doesn't suck.
And I still disagree. I think they're adequate. Leave the power stock and they survive. That's all they have to do. Like I said before, Ford and Chev just have more margin on theirs (and the Ford's always seem to actually shift instead of slipping gears for a 'luxury ride').

Yes, in my past life, I worked for DC at the transmission plant, and had several discussions about transmission, shift quality etc. 90% of the people don't want to know the transmission is even in the vehicle(IE just get me to desired speed and direction as smoothly as possible). Warranty costs were a large number prior to the 48RE. If I recall the costs for transmission warranty for auto diesels averaged around $200 per unit. Chrysler could make the transmissions for around $250 per unit. So basically they could put a spare transmission in the back of every automatic diesel sold. The advent of the 48RE really dropped the warranty costs, as in stock form it held up pretty well.

Dodge trans are my favorite... when built.
The 68 is the biggest pile of slush box chit I've ridden in.

I don't have much power running through mine(small tune probably 400HP total) but I have a tight stall triple disk with trans tuning and I really like the way it shifts, very little difference between lockup and gear changes(about 3-400 rpm drop) seems to have the right gear all the time. 5th gear with 3.73 and 34" tires is great for towing 10K.

A friend of mine has a 68rfe in a '12, and even tuned i thought it shifted very strange. And he said it shifted way better tuned than before it was tuned. I'd hate to see what it was like beforehand.
Makes me glad i got a g56. And even they have their own problems

Stock to moderate power levels, with proper trans tuning the 68rfe is the way to go. The shift quality and tow/haul functionality with a good trans tune cant be beat imo. My current 2012 has 230k on the factory auto, my last 08 had 210k on the factory auto before I sold it. Stock to stock the aisin is a beefier unit I believe , as we've had a lot of tow trucks etc come through the shop with well over 300k on the stock trans with no issues. Kind of sucks they don't have any TCM tuning that I know of at this point.

I have no idea what to buy now. I was all set to order a Aisin, then 68rfe, and now this thread makes me just want to get a handshaker or keep my '06.

I ordered an Aisin, and at most the truck will be deleted. I'll report back after I receive the truck and put some miles on it.

I don't mind keeping the power level stock if it keeps the transmission together, I just want the ability to delete it.

Not to my knowledge.
We have a customer that has a C&C with an aisin, that is loaded fairly heavy most the time. It's deleted and tuned and seems to do fine.

I believe Revmax has begun supporting up to 800HP application Aisins. Due to the lack of TCM tuning must maintain factory defuel/torque management

That is the only company I know of. No Aisin TCM tuning yet.

Called RevMax and tried asking them a few more questions, they were very quick to show they did not want to help. Couldn't get two words in. I guess they didn't want to sell parts to me.
I am thinking the 68RFE or keeping my truck until Dave develops parts for either transmission.
