Converter keeps unlocking
#1
Ok so i had my tranny changed out in my rcsb a little while back. Had tons of issue with the shop but thats another story.
Anyway i'm drivin the truck for the first time yesterday in like a month and i notice that if i try to accelerate even at the slightest peddle/throttle percent increase after about a 2mph gain the converter unlocks until i stop accelerating.
It does this every single time and seems to kinda do it on it's own every once in a while.
Also when it unlocks it's not the most subtle thing ever ethier.
It's a slight bump so to speak almost like a miss or something when it does it.
I'm not sure if it's something in my tune or the tranny itself so i'm putting he tune file up so everyone can take a look and see if i have something wrong that would cause it to keep unlocking under such light peddle.
Or if i have a problem with the trans which wouldn't surprise me honestly.

Also this is a stock transmission just like i had before as well as stock converter.
Oh and it's a hpt file.

cant read your tune, but it sounds like your settings are letting the converter slip too much when you give it gas. try setting your tcc solenoid min pwm to 90 everywhere and max 100 everywhere. see how you like that, it might be a little too firm so you can back the min down to what feels better. i think mine is like 30 min

Anybody with hptuners can you tell me where the tables he is talking about are?
I can look at em but i always miss stuff on the tcc stuff. Where/how do i get to those tables?
