Automatic Shifting


Could I ask for someone's help. Last week I bought a 2008 GT/CS with a automatic transmission. Is it harmful to the transmission if I'm shifting this car by hand?

For instance. I was driving down a local road in "drive" and when I was coming close to the on ramp to get onto the highway, I manually downshifted from "drive" to "3rd" then to "2nd"

Then once I was on the ramp I kicked her down and shifted through the gears back up to drive. Will this hurt the tranny?

Don't see why it would hurt.If it hurt the transmission,they wouldn't put in shifter to let you do it.Computer is smarter than we are but I shift mine sometime just for fun.:kooky:

I do the same thing with mine, ours just don't downshift very quickly when letting off the gas. I've driven a few of those German cars with autos and the paddle shifters and even without using the paddle shifters they downshift so quickly in sport mode you barely need to touch the brakes. If you want to slow down fast in ours, you need a combination of manual downshiting and brakes. I've always done it that way with all my cars and couldn't imagine the Ford engineers would design this to be harmful. Just my $.02.

It isn't harmful but it's so far less than necessary unless you've got more than just a few bolt-ons in your car. If you're talking about competitive driving.....well doing it with an auto is probably a bad idea to begin with, but just accelerating the computer can do it better than you ever could by hand, you also run the risk of redlining.

Personally if I'm not launching the car there's a bit of a tip in problem with the TPS if the car's in drive. So if I want to leave a stop light with any sort of grace and civility I have to shift myself. And if you've GOT to go from a roll then you can shift down manually to get a better start, but from a stop "D" is the way to go.

I shift mine all the time too especially on secondary roads or heavy traffic. I've had my TCI shifter for about a year, and it woks as advertised.

I have been manually shifting my 01 auto for 20,000 miles with no problems. I like to better performance my car gives while shifting. Just watch the redline. Good luck.
