Excellent content! Question.... What about the purge enable function? Us guys who add to the clutch stack up on the 35r and 456 clutch packs....we get kinda tight on tolerances. Gm hard wired a clutch purge to happen on every new drive cycle just after the 2-3shift to quickly apply the 456 clutches assuming to purge air (?). Well that causes a small "bump" or bindup which totally sucks. So disabling the feature prevents this function. Thoughts on this solution??

@cpwood2888 9 ай бұрын

would I lower the oncoming pressures and increase the oncoming volume to stop a shift bind? 2-3 clutches are too tight when rebuilt(guess). I'm getting close by increasing the volume but the reset causes terrible flares until the adaptives start kicking in. About a week or 2 later she starts to shift harder. I never liked that it had to flare until the adaptives took over but what you said at the end made perfect sense about the adaptives telling you "no dummy that doesn't work".

@Matt_Sanford 9 ай бұрын

The trick to getting one not to bind is to watch the datalog and determine which part of the shift is causing the bind. If the flare is bad and then it binds after the flare you would increase Oncoming and decrease Offgoing. If it binds then flares, you would decrease Oncoming and increase off going. This is actually the reason why I don’t like clutch height being altered from factory but you should be able to get it dialed 👍

@cpwood2888 9 ай бұрын

If I set it back to factory settings it doesn't flare that i can tell. The shift is violent and the final shift time is 75 mil sec. I then understood lowering oncoming volume would reduce flare so tried increasing until it started to flare. the adaptives then slowly bring it back to hitting like mike tyson. I tried lowering the oncoming pressure and it seems to help little by little but unsure if I'm doing something terrible to the internals. @@Matt_Sanford

Putting in 0 slip causes the TCC to shudder/fishbite worse and will eventually destroy the clutch faster, they are designed to slip but poorly designed, flawed from the factory. GM did this more on Gen V to meet mpg with the EPA. the 3 rpm minimum slip on AC creates a lot of shudder and issues. The oem torque converters are defective from the factory because they do not have enough area of friction and warp from heat in their design. The only fix is to replace torque converter with a billet converter that resolves this area overheating and friction. Also from 2014 6sp and 8sp trans have a built in cooler line thermostat causing the transmissions to run at 195* F before opening. You can flip the pill and spring inside to make the cooler lines flow all the time. Set all your slip rpms to 20, only time you would put 0 is if you have a tripple disk converter but you will also have to change other parameters to get it to stay locked. Some GM operating systems as we have found out in HP tuners will not keep the converter locked. Working in a transmission shop and tuning with Hp tuners I have seen a lot worse issues with people trying to 0 these slip tables out. It will make your factory junk torque converter grenade faster...

They still slip with the setting set it 0 slip. It just has the ECM PWMing the converter to attempt to maintain lock versus chasing a higher rpm slip.

Of ALL of the years of working with transmission shops and converter builders… you are the ONLY one that has ever made that statement.

For me, it hasn’t mattered either with some slip or zero slip. I will say that the video helped with the shifting a ton. Can’t thank you enough for that. It was good before but now it feels like it’s putting more power down. Best time on my draggy was 5.5 0-60 now I would expect it to be much closer to 5.25. But my converters…. I’ve tried every thing I can get my hands on. Every video I could find that makes sense. Paid for books and even a few “experts” still have bad luck with the tcc. Has all the hardware goodies short of a dedicated drag truck too. Even with this video I have tables that don’t match with yours and all the others and so I have to make compromises or estimate what it would be, with my fingers crossed. But again, I’ll keep watching, this video and the burn-out one helped a lot. Thanks
