This is all about attitude adjustment — for the Yankees and their fans.

This is a new era for CC Sabathia. Throw away the radar guns ... for now. No more Velo Panic.

For a game addicted to speed readings, that’s going to be a difficult challenge, but it must be done. Life is no longer about blazing fastballs for Sabathia, it’s about location and keeping the hitters off-balance. And when done properly the results can be fabulous.

Can this new Sabathia pull off this winning transformation?

Judging from yesterday, he can be a resounding success. With a fastball that sat at 90-91 mph most of the day, Sabathia baffled the Tigers’ hitters in a 7-0 win at Comerica Park. There was a 13-mph difference between his fastball and his change-up. The Tigers could not pick up the spin on the baseball. As a result Sabathia was able to succeed with his four-pitch arsenal.

I like this new version of Sabathia because it’s like watching another version of Andy Pettitte work his magic. It’s called pitching.

Sabathia pitched seven scoreless innings, giving up only four hits. He struck out four and walked three. The previous two games the Tigers scored 16 runs, so Sabathia’s success with a rather average fastball is worth noting.

That was good enough to beat blazing right-hander Justin Verlander, thanks in part to a stunning second-inning two-run home run from Jayson Nix, who had been 1-for-11 lifetime against Verlander with five strikeouts.

Listen to Pettitte’s insights on Sabathia:

“This guy can throw four pitches for strikes,’’ Pettitte told The Post. “He knows how to pitch, he locates, and he’s going to win. The problem is when you can’t locate. A lot of guys aren’t strike throwers. He’s a strike thrower. If you are wild, you can’t survive.’’

Sabathia’s velocity is down, but his pitching ability is up as he evened his record at 1-1 and gave the Yankees another big win.
