High Output (AISIN) vs Standard (68rfe)

[sstoner911]

Actually, not. If you do a search on AutoTrader or other nationwide search engine, you'll find many C&C Ram 3500's with high end Laramie packages including just about every option the pickups have. I was considering going the C&C route and adding a hauler body in back, specially equipped for 5th wheel service, but decided I'd like a bed to slide lumber/cargo into on occasion.

Most of the Hotshot guys have Tradesman or Laramie trims. Just depends on the driver I guess...but for the most part they don't want a huge payment.

I was just responding to the post suggesting that one had to forego amenities to go the chassis-cab route.

I guess it's not that have limited options in the C&C.... probably more of a choice considering what the primary use is. Mine is a mixture so I don't mind more creature comforts.

This is a good tread. I bought my 2020 Ram 3500 to be able to haul my 17000 lb dozer between farms leagally. Then the CP4 failures raised there head and I was able to trade for a F-350 SRW. So lost my hauling ability for legality. Was able to trade back to a 2021 Ram3500. LOL, 3 trucks in a year and wife let me do it. Anyway, the 2021 is quite impressive and I can haul the dozer. That said it is excellant in the towing department and with Laramie trim I think it is fine. When it is just the truck I swear I only have to barely touch the gas pedal to slip thru the gears. The torque on the 6.7 Cummins is unbelievable. I worked as a mechanic at UPS and we had several 6.7s. They proved to be a very good engine so that is why I went with the Ram.

Hold on... So you traded one cp4 Ram for a cp4 Ford assuming it was a diesel, then traded back to a Ram?...

Opps sorry. The Ford had the 7.3L gas motor. Had another truck (old International Flatbed) to use for dozer hauling but it was an old 7.3 non turbo and it was slow. The 7.3L gas was ok, but the DRW was needed to be on the highway legally. So went back to the Ram 3500 DRW with the better fuel pump and rating to haul what I needed.

it's the same engine, just marketing ploy

Untrue. There are numerous changes between the two engines.

Quite a few internal changes such as injectors, compression ratio, etc.

im well aware...wanted to know if the i joined just to post that guy knew and was willing to actually participate or if hes just another naysayer without any legit proof....

Only the pistons and tune are different between HO and SO. CC gets a few more changes (looks like cam).

That's odd to me that the CC is 10 less HP and 50 lb/ft less torque and it has a different cam and head? I always just assumed it was a tune only difference. Wonder why the different hard parts?

Different designed rpm range. The C&C peaks its power at 2,400 vs 2,800 on the P/U motor.

It’s also designed around a higher average load.

How can long block part numbers match if the pistons are different?

I probably got that one wrong. I'll go back and check again.

Regardless, the pistons are the key differentiator on the SO vs HO debate.

My HO was built December 2020 I now have 75,000 miles on it 70,000 miles of that is towing a 12,000 pound trailer daily in City traffic.
I absolutely love the transmission for pulling my work trailer. When unhooked and not in Tow mode, it acts a little confused at times. The transmission is perfect for what I do with that particular truck. Fuel economy sucks with the HO when pulling I average 12 to 14 truck does not have high gears, I’m getting ready to order a second truck for personal use vacation and cruise around town occasionally pulling a small trailer. I am not going to go with the HO this time around due to fuel economy.

Some observations about the AISIN transmission in my 19 HO. Maintenance is very expensive, much more than I would expect for a present day transmission. The transmission requires an oil change every 30K miles which at my dealer is about $400. Then at every other change, it requires an oil/filter change which is $765 at my dealer. So in 60K miles it has required over 1K in maintenance, yes its possible to do it more cheaply, but wow! I'm used to transmissions wanting an oil/filter change every 60-120K miles. My Ford F-450 also requires 30K fluid swaps but it costs $165 at the ford dealer..... The fuel filters are made with gold too I hear at RAM dealers..... I spent $1720 to have transmission fluid/filter, front diff, rear diff, transfer case, and oil/filter change done at the dealer. Pricey, for a work truck! We will be finding an independent for this fleet truck's maintenance.

I also find the transmission has its refinement issues. It can have a rough 1-2 or 2-1 shift with very light throttle (not all the time). It can also get overly aggressive with downshifts, when driving in hilly eastern Texas with the cruise set to 55mph, it will sometimes while climbing a hill jump from 6th to 3rd like I'm going to pass (which is way overkill, maybe a drop to 5th or 4th). Also notice the transmission hunts a bit in hilly terrain, so I use gear limit to keep it in 5th or 4th and below. Don't take this as critisim, just stuff I've learned since owning it. It shifts perfectly with a heavy load, like its downshifting to slow loads automatically on hiills, and its smooth when towing.

Also the rough 1-2 2-1 shifts on light throttle are really noticeable and head tossing when in 4 low. While this transmission is very reliable, which is why I got it (routine maintenance on the ford is every 150-170K replace the trans). Its not as refined as more modern transmissions circa 2020, feels more like a DSG from the mid 00's.

I have a 2019 HO/Aisin. I had similar transmission shifting issues until the dealer updated the Transmission Control Module (TCM) with the latest version per TSB 21-020-22.

My Aisin trans is flawless (knock on wood) none of the issues you described. As mentioned there's a flash for this shifting issue.

I also did my own fluid change and will do the filter and fluid when it's due again in a little over 20k miles.
