Thank you 74 Beeper!
Ill take a look at that today. I was focused solely on the bell housing.

I’m very close to dropping the transmission. I just can’t seem to come up with the right tool combination to get the torque converter bolts out. There is not enough room up there to swing a ratchet. Any suggestions would be greatly appreciated! I am thinking a 1/2 drive right angle impact would possibly work?
It’s slow going.... I used a 3/8 drive with a 3” extension.

Well....I’m going to show my stupidity here, but I feel you all should know my problem is fixed.
I called Revmax (Great Great guys) last Monday to order my transmission. Speaking with them, I learned that the TCM would need to be set to Re Learn after the new tranny was installed. I told them that the dealership said there was not a new Re Flash to be installed. They said it’s called a Re Learn, and that I should check to see if that was done yet.
Turns out the dealership had not done that because I was asking for a Re-flash. I ended up putting everything back together and took her back in. They did the Relearn and she’s shifting like brand new.
I want to thank everyone for there help and input!!
That has to be a huge relief to you. It’s amazing that that wasn’t looked at with all the troubleshooting that you went through. I’m glad everything worked out. I’ve been told that problems with these transmissions are very uncommon.

Thank you very much for this thread I’m having the exact same issue on my DRD tuned and deleted 2018 Aisin.
Looks like I’ll be heading in for a relearn.
I noticed the Aisin (mine’s a 2016) shifts way better on 120-150 tunes... don’t know why but the truck just feels like it’s “light on it’s feet” and I’m not pushing the pedal too much.. but overall shifts 100x smoother then ever before.

Just loaded a 120 hp tune into my 2019 3500 aisin truck. And wow, it feels good, no overly hard shifts, no flare shifts, just quick and smooth. Possibly the tcm relearn is better on these 19s. On my 13 it was ****, anything over a 60hp tune was nearly undriveable. This one ive only put a few hundred kms on tuned, but even at WOT it feels great. Huge improvement. As far as your 18 goes, id suggest a private tuner, the box tunes are dog **** in that department. Go to DRD tuning, or a good private guy. I got mine through optimal welding, and chances are he can smooth u out alot compared to a box tune.
I’m running box tunes only on my 16 and it’s literally perfect at 120-150.

Granted the non-Aisin folks can do good with lower duration tunes but the higher ones work best for us Aisin folks.
I get it everyone loves to talk about custom tuning but another $500-700 on a device that costs double, no thanks. Now if you’re competing or running compounds or bigger fuel system then it would make sense but then go put your truck on a dyno and get tuned. If not, I can’t drink the kool-aid that everyone’s been drinking... best example was the PPEI flavored LOL
I’ve seen Raceme step up and work out kinks more than people would assume.
The guy writing all the tunes for Raceme has been tuning Cummins since the late 90s if that makes it worth any weight.
Transmission still shifting good? My 2018 with 50K just started the poor shifting, I am thinking I will go to the dealer and have them set it to 're-learn'.
