I bought an 2018 Ford Focus Se last September in 2020 at BobSwope Ford in Elizabethtown, Ky. It had a little over 25 000 miles on it, now it have a little over 29,000 miles on it, not quite 30,000 miles. First, was this a good purchase? Second, when should I change the transmission fluid and transmission filter in it? It is an Automatic Transmission. It's making an shudder from first to second gear; or when I take off from an complete stop. Other than that, it seems to be fine and shift fine in other gears. Please help as this concerns me. I love your videos and watch your videos all the time. Keep up the great work.
Well it's yours now so make the best of it.
What does the manual recommend for maintenance?
If it were my car, I would do a drain and fill now and again at every 20000 to 25000 miles. Filter around 75000 or less. You could try the additive Shudder Fixx. I have never used it but a transmission shop owner told me it works.
