Winterbottom confirmed his departure from the team at the ITM Auckland SuperSprint as he appears set for a move away from the Blue Oval with the Preston Hire Racing Holden concern believed to be his destination for next year.
While his 2019 plans are yet to be confirmed, the 37-year-old admits the prospects of next season will mask some of the emotion around his Tickford exit.
Although, he is nervous about any pranks the team may play on him following his final race at Newcastle.
“I'm nervous about what they're (the team) going to do to me after the race, to be honest,” Winterbottom told Speedcafe.com.
“It's emotional, but I'm so excited about next year, that it's kind of overriding the emotion at the moment.
“I'm going to be really bad when it finishes and stuff like that, but I'm so excited about what's happening next year that, it's taken away a little bit from the ending because it's a new beginning.
“I'm also looking forward to the new chapter
“It feels like Day 1 starting next year. There are a few emotions going on, but I try not get them when I'm on the grid, or when I come in and all the boys come and shake your hand.
“And that's when it hits home that you're leaving the team.
“We'll announce it soon what is happening (for next year), but I'm really really excited. My expectation of next year is to be quite strong.”
Winterbottom joined Tickford in 2006 after two years with Larkham Motorsport.
However, his final two years have produced a lean spell with his last victory arriving in 2016.
Having forged relationships with staff over the period he admits it will be hard to leave.
“They (the team) put their absolute backside into it and go above and beyond what a job description is and everyone in most sports does,” he added.
“Every department, even if it's the new guys and everything, you go above and beyond what the job description is and that's… you feel bonds and stuff with each other that is far more than work colleagues.
“That's the emotional part, you're walking away from good mates and stuff like that, but the good part is that you're still going to see them around (next year).”
The Coates Hire Newcastle 500 will begin next Friday.
