Does anybody know what the converter lock up duty cycle should be on a 2000 silverado? Mine is 30% and keeps unlocking driving down the road under norm conditions. Fell that did my trans used a tech 2 and said its to low.

Also iv had the TCC fix done to it if that helps.
I set my min to 95 and max to 100
90 min and 99 max is also popular, and everything in between.
Basically you don't want you max below 99 and the min below 90.
This will make lockup solid and firm like a on/off swtich. Your lockup tables may need adjusting too.

Ok cool, not sure how come mine is so low, ill see if nelson can fix it for me. Also if i have them turn the shift pressure down on my sec, that will soften the gear change right?
I would leave shift pressure stock in the tune. Is the trans stock?
