Unless you like replacing transmissions, do not try to "launch" your automatic except the 1/8 second between your brain saying "brake foot, lift" and the car starting motion.

 

By auto-launching I don't mean revving in neutral and then changing into drive, I keep it in drive, hold down the break with the left foot, slightly apply gas to 1800rpm, slowly let go of break. Does that still damage the transmission? it's still in first gear though. I heard it's stress on the driver train...?

 

oh hell yea it can cause damage. repeated brake launching will wear out the torque converter and all the fins inside it that hold oil, next will be the differential that the halfshafts connect into. not so much the gears in the trans, but the torq converter yes, and the diff will take the initial beating... both expensive. but hell, it does help on the launch, and its your ride...





and sorry for introducing you to your rev limiter like that... i guess i should have asked if youve done that before... my bad

 

Welp good thing im still under warranty lol!

 

that only helps if it fails while under warranty. Warranty +1month and it fails because you are being silly now, and you're screwed.

 

All good, I still got...130,000 left on my warranty. So if anything happens, I'm alright. I'll stop auto-launching it tho lol. Any components that I can upgrade so I can auto-launch without fawking anything up? like a upgraded torque converter or something?



Btw, I just installed a gibson exhaust tip

 

I'm pretty sure it got more complicated, but a manual transmission swap should be high on anyone's list that wants to be racing and not replacing Hyundai automatics IMO. On a more serious note, if they still put under-rated ATF coolers in and call it "normal" for the fluid to turn brown in 10,000 miles, you might want to look into a transmission oil cooler, preferably with a thermostat control.



Fun factoid: for the RD platform, the ATF cooler was a loop of tubing inside the radiator. They all run 10-15 degrees too hot and burn the ATF really fast and Hyundai got away with calling this normal.

 

even with the 2010 model?



btw is my angine the beta or the alpha engine?

 

You have the Alpha.

 

If your ATF goes from red to dark in 10-15k miles, you want a supplemental cooler. I don't know how the 2010s are; I would HOPE they fixed it by now.
