Hello, Has anyone swapped an 8l90 for a 10l90? I would love to know if this has been done/ if it's possible. Looking to swap out my 8l90...

Hi Yall, Wondering if anyone knows what the torque specs are for the front driveshaft connecting to the differential? I need to loosen the driveshaft in order to access the the t-stat so I can install my tbv kit. It's pretty much impossible to access the t-stat housing with the driveshaft where it is. Any help would be appreciated!

I have scoured the internet to try to find definitions for the different parameters for the tuner. Are they on the website? I would love to have some specific descriptions of what the functions are. Can anyone point me in the right direction?

You mentioned a '15 as pre-shudder; I have read a lot of threads on here about that. I feel lucky to have a year where this is not a problem. Do we know what the general cause of the shudder is (in a nutshell)? On a entirely different note, is a "diablew" tune worth it? I have the Diablo i3 Platinum I believe and I reprogrammed some of the shift parameters in 1st-2nd gear. When it shifts from 1st-2nd, the rpm's jump, (clutch?) any thoughts?

What is NHT?

Can you recommend what the best solution is? I know horse feathers are a nice aftermarket part and all...

What are normal operating temps for the 8l90? On roadtrips it will hover between maybe 180-190ish. I read the topic concerning the 6spd so was wondering if the same problems are encountered on the 8spd. I have 6.2 manufactured in May of '15. I also live in a cold climate where winter mornings are below 30F routinely. Sound like the the "new" gm thermostat is the way to go??

Ok got it. Have you used a custom tune? If so, what's your experience?

So I've tuned my truck with and it has made a difference from what I can tell. A couple of questions, however. 1. Is there any way to truly fix the hard downshift from 3-2 and what I call lagging going from 2-3 under acceleration? I installed the 91 octane tune, disabled AFM, speed limiter and changed the shift points from 2-3. It seems like the shift point pressure is too much. The RPM's spike when i'm easy on the throttle after a stop. 2. There is an option to change the axle ratio via the tuner which I thought was impossible because the axle is ratio is mechanically fixed, yes? I think I have the 3.23 but I am not 100% sure 3. Side note, I have an Air Raid intake tube, k&n filter, installed a catch can and did a muffler delete. I took out the flapper valve out as well. Truck runs and performs better (sounds awesome too). When I go to pass cars on the highway, I can easily break 100 and you can tell the engine still has a lot left. I truly believe that this truck's engine life has been extended greatly after disabling AFM. Thanks guys.
