I've been down that road too many times to list them out with vehicles from Ford(several), Chevy(including a successful Lemon Law), Volvo, and Toyota. Is this annoying? Yup. Does it rise to dump it level? Nah. Too many folks have accumulated a whole lot of miles without catastrophic failure to be a big worry. Actually, the only cam failure I ever had was in a well maintained 454 Chevy in a rollback, so, while others may feel Chevys are bulletproof, my experience with all three I have owned ras ranged from poor to "holy ****!". I am sorta hoping for a better transmission to come along, and that might goad me into trading up.

Don’t worry,

There is one that has nine little round toothy things inside it that is being tested in the HD’s

I hope it's better than the 9 speed that's in the Ram Pro City. That thing is constantly shifting 9,8,9,8,9 with the slightest load change. After driving it all day it makes me appreciate my 8 speed with MDS.

Straight 0w40 PUP was noisy ( not overly so but enough to make me search) straight 0w40 Amsoil was a little quieter until about 2000 mile in it started cold start ticing for a solid 3-5 seconds EVERY startup.

Wanted to go to straight Redline 5W40 but the calcuim, zinc, phosphorus and moly were significantly lower than other redline formulations (still higher than most all others oils though). Since it was about to be winter and i have a grudge against the boat load of VII’s that are in 0W40 oils i decided to do a more winter friendly mix of 4quarts 10w40 & 3 quarts 0W40 to get a 7W40 that had EXCELLENT calcium, zinc, phosphorus and moly. Redline 0W40 and 10W40 have a killer additive pack so I thought i could try and get the best of both worlds.

Not a single startup tic after 50 miles into redline and non since.

Now im running my summer oil straight Redline 10W40. I dont notice a significant noise difference but it is slightly quieter. I can hear the noise injectors more now.... LOL.

My current mental battle is deciding my next winter oil change as i want to get away from mixing if i can. Considering straight redline 5w30 or my personal demon.... straight redline 0W40.

I just strongly hate VII's so im leaning twards 5w30.


What is the cst vis @100 of PUP 0w40? If it is close to redline 5w30 than im just a little hesitant.
The 2,100 mile oci here was a 50/50 mix of PUP 0W-40 & 5W-30 with a cSt of 10.6 , the 5,000 mile oci just before that was Redline 5W-30 with a cSt of 10.9...the first oci on the page with 8,074 miles was also Redline 5W-30 , sorry to add to your frustrations my friend ...

Ive been using red line 5w-30 for a while now. Not sure if it does anything different than other oils but I hear good things about it so I use it.

RLK: One thing for sure PUP has exceptional lower numbers compared to other oils.

That is one great looking UOA.
Even though it was only 2000 miles.

TBN was 5.6 this combo could easily withstand a 6K-8K mike OCI.

So the more I look into Trans pans, that exhasut cross over pipe on the 6.4 seems to be a headache. U&A didn't you do a Mag Hytec or a PPL?

I hope it is geared correctly for a gas motor, and not a gearset they are going to use with the Cummins, AND I hope the control/operation is as tight and right as the ZF 8 speed, always the right gear at the right time.

I went with Amsoil Sig. Series syn. ATF because it meets MOPAR's specs for my transfer case.

I got 4 quarts because I tow a lot and will change the fluid every 30,000 miles. And joining for 6 months $10 saved me $4 because I got a 25% discount.

Nope,

You just want to see the mufflex setup?

Mine is different than the one for the 2500 because i have rear leaf springs.

I used this in my 44-44 for about 6 months. It definitely shifted between 4lock and 4low smoother but it just felt like the clutches slipped quite a bit more than they did using the unicorn tear fluid. I ended up draining it and putting the unicorn fluid back in and it was a noticable difference in clutch engagement, but it doesn't shift as smoothly going into 4low.

Interested to see what experience you have with it.

No issues besidtthe fact that i am not really in love with the sound. I shothave went solo proformance muffler delete kit. But with the resonator off it made it substantially better


Nick@gotexhaust sells them.

Yeah, I just ant that magnaflow sound like you have, vs the muffler delete kit. But I understand what you mean by it not sounding like you want.

According to this chart we have different transfer cases. The Amsoil I got meets the specs for Mopar 68089195AA

Did you notice any difference when in 2 wheel? I never use 4X4.

Thanks

Oh yeah I just noticed you have a 2500 so yes we have different tcases. In your case the Amsoil MVATF will work fine because you have no clutches.

To answer your question no I didn't notice anything different in 2wd

Just as in the differentials, the HD transfer case is very different than the 1500. It uses a chain, sprockets, planetary and annulus gears. No clutches.

Edit: Sorry, just saw you had reiterated.
