2014 converter lockup issue.

[Mike-hp]

Hi guys! My name is mike and im new to this forum but not new to the tuning sense.. Lol
I have a 2014 silverado that recently installed a TCI converter. Im having problems with partial throttle lockup. Im locking it in 5th gear only but when loggin TCC pressure, it read 40-80psi and converter feels horrible. Once i lock it manually with vcm scanner, TCC pressure read 594psi which is the max pressure that can be applied and converter feels awesome.
I already calibrated TCC pressure tables but still lock up pressure is very poor

Has Anyone experienced this issue??

Thanks in advance!!

Can you post your tune it might be as simple as increasing the duty cycle of the apply sol

Has anyone installed a converter on these models and experience this issue??
Ive installed lots of converters on 2012-13 silverados with 6 speed transmission and everyhting works perfect.
Its just on these new models that im having prooblems with.. Just need more pressure applied on TCC.

Already did and same thing.. I just need that pressure to be applied. Cant find the problem

you have full throttle TCC stock make it it stays locked max them out.

Adjust your misfire tables. Just max them out for right now and see if that takes care of it. I know with small diameter, high stall converters we use in our G8's it will cause the lockup function to act up terribly.

Set ALL TCC desired slip tables to 0
DOD slip is enabled. Disable it.
Min Slip AC On, set to 0.

I see you dont have regulator gain settings. That might help if you did...

I had already max out the misfire tables .. Converter does lock up just needs more pressue.. 6l80 from 2010+ silverados dont do this.
Already tried to zero out my slipagge and still only 40-80psi applied very different compare to locking ot manually with scanner.

Im not worried about full throttle right now. Just need to fix partial throttle lock up at the moment. Drivability feels horrible.. Rpms jump up and down once tcc applies.

[Mike-hp]

In few words. I just need MORE PRESSURE to be applied to tcc.

apply ramp, increase by 5% to start on the 120-200 slip up to 2800 rpm

Set ALL TCC desired slip tables to 0
DOD slip is enabled. Disable it.
Min Slip AC On, set to 0.

Setting all TCC desired slip tables to zero, is this common practice on the stock TC too, or is this only for aftermarket?

[Higgs Boson]

ive set slip to zero on many stock applications.

On both, trucks and Vettes?
