Possible transmission problem?

Tarheel_6.4L · Aug 7, 2014

I'm running the H&S mini maxx on my truck with the shift schedule set to lock the torque converter up in 5th right around 56mph. The other night when I got on it, my mini maxx showed D3 TC locked. Is this normal or should I start saving for a new torque converter or transmission?

that is no problem. in fact-it is better on the trans

two things can make that happen, one is the temperature of the trans and two is the speed at which you floored it.
