Simple habits that can wreck your automatic transmission
Automatic transmissions cost a lot of money to fix if they go bad. Rebuilding them can cost three, four, even five thousand dollars. So you want to take care of them and I'm going to show you these simple things that you need to avoid if you are driving a car with an automatic transmission.
Driving through flood
Now you never want to drive an automatic car through deep water and here's why, there are holes and vents on automatic transmissions that is meant to contract and release pressure when the transmission fluid gets hot.
And if you go through water that will suck water into the transmission, and let's just say water and automatic transmissions do not go together. If you get water in your automatic transmission sometimes you get lucky and flush it out and it'll work. But often it will destroy the entire transmission and you'll need a new one.
Changing from Drive to Reverse while moving
Never accidentally have your car go from drive into reverse while the cars moving. Make sure you don't accidentally hit the stick and rip it into reverse while you're driving down the road, because it will destroy the transmission.
I've had my neighbor's teenage kids, when they're learning how to drive and screwing around with their friends, do that hit it in reverse and they just destroyed the transmission. They just ended up junking the car.
Putting the car on Drive while idling
The next thing not to do with an automatic transmission car is leaving it in drive if you're idling for a really long period of time. It can lead to overheating of the inside of the transmission.
If you're going to be sitting there for really long time just shut the car off or at least put it into park, because in Park, it's not directly connected. The torque converter isn't sending a lot of power so it won't get quite as hot in park as it will and drive.
Doing burnouts is one of the worst things you can do for an automatic transmission, and of course burnouts aren't good for any car. Burnouts are for standard transmission cars.
Non-replacement of Automatic Transmission Fluid
If you have a later model car, don't listen to this nonsense this says no need to replace ATF under normal driving conditions. It's a bunch of nonsense.
Modern cars use synthetic fluid that can handle heat better and break down less, but eventually it does break down, I still say change your transmission fluid every sixty to eighty thousand miles, regardless of what these ridiculous directions say.
