LilSick - Lucid, clear, crystal and transparent. Totally makes sense.

Traction, friction, load, acceleration and a lot of tune tables that involve engine RPMs, torque, gear ratios, axle ratio,...

Yes. We both agree. Like you, in anticipation of someone telling us your problem is (the commonly used statement), "you don't have 315s and your not running on a sticky track". That's why I added it...

Sorry to hear that.

I went the tune route at first, with many attempts and no success. Then I did the hardware route with the rebuild and limited success. Further tune attempts to tweak the tune...

Awesome. Good luck on your rebuild and torque converter. I assume they chose the spec converter for your horsepower and the stall best matched to your cam operating range, duration, and driving...

Yes, correct for flow.

That means 2nd gear for "energized" solenoids:
E = off, open (to engage E clutch); low or no current
C = on, closed (to disengage C clutch); higher current depending on...

Thanks!

Apparently, the solenoids are actually more complicated than I thought. They are not just on/off fluid switches. They are normally open or normally closed variable force PWM solenoids...

Found this a while back. Can't find the source
[UPDATE 1/20/2024] - Apparently these are the clutch diagrams and not solenoid. I think captured from a video.

The trans can run over itself. ROTFLOL :burnout: :drivin::burnout:
Your ride sounds awesome, no nappy time for the kids.

Mine sounds like a sewing machine compared to yours:...

I could not find my log, data, or playback showing commanded gear #2. I only had one in park as illustrated. Same with the shift solenoid valves, the commanded gear is not showing. I will need to...

I can definitely see how a sticky track changes everything regarding the tune and much easier to break stuff. However, if you smoke the tires on a safe street, can you get a successful 1>2 shift?...

So sorry it did not work. You get an E for effort or E for E clutch, the one that engages for the first time in 2nd gear :rolleyes:. Sorry bad joke. Laughing is better than crying.

My supercharged...

Any update on a Fix?

My 8HP70 $3,600 trans rebuild was more for longevity with the Raybestos frictions and Raybestos Kolene treated steels and valve body Sonnax Zip Kit (Shift Kit) to handle the...

No mention of this in our private conversation

I will be holding off on the tune. I found a deal with a great discount for a beefed up, tested, tuned, and installed 8HP70 good to 900WT (Ft Lbs. Wheel Torque). The highest I may ever get is 640WT....

DYNO RESULTS - 562WHP (SAME AS STOCK HELLCAT DURANGO):

Example Stock Hellcat Durango Specs and Dyno Reference Comparison:
Using an 8HP95 (900Nm) transmission, a "stock" 2021 SRT "Hellcat" 6.2L...

OK. Thanks!

My first pre-dyno test was a 5.0 Mustang yesterday, on a second gear rolling start. Smoked it. I got a lot of WTFs and laughs. Since the new "stock" Mustang comes with anything from...

Had delays due to fuel delivery issues. Dyno scheduled for next week. The compression is lower on this forced induction 6.4L (9.7:1) to run on 93 octane pump gas. Hoping for 550-650 (Dynojet dyno),...

DodgeBoy, I responded to your email. Thanks.

Same Issue!
1-2 holds @ 50% or lower throttle, above that will trigger rpm limiter and limp mode. WOT shifts from 2nd or higher are fine. Prefer to resolve 1-2 shift issue before dyno.

comp 270...

That makes sense. Thanks

OK. I was not sure if changing the displacement would impact any of the tuning tables. Thanks for confirming there is no reason to change the displacement unless I wanted to loose important...

OK. After tuning through VE, can NN be retaught and enabled or do most people leave it off?
Also, I noticed that if the displacement is changed to anything other than the stock 5.7L OS then ESP/TC...

LilSick,

Thanks for your post. Absolutely. All good points.

I have a 2017 Durango 5.7L to 6.4L swap with the 2.9L Whipple. The Whipple calibration and kit with the 63lb injectors is for my previous 5.7L engine on the PCM with 5.7L OS associated with my VIN....
