Is the Aisin worth the extra $ over the 68rfe?
I had the understanding that the 68rfe was a pretty darn good transmission in its own right. Is the Aisin worth the extra money? What is it about the Aisin that separates it from the 68?

Winner winner chicken dinner!
If you have the money buy one, if you need the capacity buy one, if you need a PTO buy one, but for the average guy the 68 will do.
From all owner reports they drive different so I would say test drive them back to back, good luck.

I would say that the Aisin is somewhat better than the 68RFE but they are having alot of troubles with the torque converters in them right now.
Here is a link from another member on the issues he had:

In my opinion, all of the Dodge CTD Transmissions are weak in stock form and the FIRST thing I have done on all my Dodge CTD Transmissions is to rebuild them with better TC's, more clutch capacity, higher line pressures and always a heavier flex plate. The stock 68RFE torque converter is not much different than the early TC's in the 47RE transmissions which only have one disc with about 34 square inches of lockup clutch surface area versus three times that with a triple disc converter. If you are towing heavy or running any additional power adders that is NOT enough!

Then regardless of which transmission you choose I would highly recommend upgrading the internals as soon as you can.

If that's the case, I'd rather just get the Aisin. I'm not very fond of buying a $50-$60k truck and then have to dump more money into it just so it can perform the way it's supposed to in the first place.

Sorry to be the "bearer of bad news" on those Dodge Transmissions Sir. Between the two, (68RFE or Aisin) the Aisin is the better choice but as I said they are also having issues.

If you are purchasing a DRW cab chassis and plan on putting a dump body on then go with the aisin . These are the same trannies that come from the Isuzu truck and have PTO capabilities. Or if you are towing hauling all day everyday heavy go with it if not, not worth the money

If the insurance isn't too bad, I wouldn't mind a DRW cab and chassis, especially a 4500 or 5500. If the insurance is too much, I'd have to settle for a 3500.

all this mess about having to buy the truck and rip the 68rfe out immediately..........This is a much stronger transmission in stock form than yall are portraying it to be.

Well if they are left COMPLETELY STOCK they might be alright but I have slipped them by adding 60 H.P. programmers! So, if you plan to modify your 4th Gen my advice is to upgrade as I said above.
