Automatic trans help in 05 S

[up_yours_7]

I want to change the fluid anyone done it before and anyone got a tutorial on doing it?

Jack up the car, remove the drain plug (14mm) on the tranny pan, let the tranny fluid flow out, reinstall plug with new crush washer, and add the amount (~3.4 qts or so) of T-IV that was taken out through the dipstick tube. Start the car and shift slowly through the gears and check the level after a 20 min highway drive on a level surface with the engine running.

Buy 4 qts of T-IV from the dealer and a crush washer and might as well get a new drain plug. Doing multiple drain and refills is a good and safe way to get new fluid into the system.

Check out this link for pictures, although they are not exactly drain and refills

I just bought a '05 Corolla S auto with 66,000 miles on it. I've put 2000 miles on it in 3 weeks. When should I change the trans fluid? Is T-IV the only brand - I assume that is a Toyota variety? Are there any synthetics that are worthy? Amsoil, Mobile 1, etc?

Thanks.

Change it now, T-IV does not hold up well, it is not the greatest fluid. Color is not an indication of quality, but smell is. If it is smells any where remotely burnt, change it. Redline D4 and Amsoil ATF are great compatible fluids, however they are not approved by toyota. There are a few others that are compatible too, Mobil 1, castrol, and RP to name a few. Read the labels of the ATF to find out if they are compatible with Toyota T-IV. I run D4 without problem.

The only fluid approved by toyota is Mobil 3309 and their T-IV, which are the exact same fluids. 3309 is very rare to find. Toyota does not make any fluids, T-IV is just re-bottled 3309. T-IV can be bought at the stealer ship for about $5 a quart. T-IV is not a synethic fluid. If you decide to change it, multiple drain and refills are easy to mix old fluid with new fluid, as a drain gets less that half of the fluid out of the total system, but is expensive. A cooler line flush is more efficient at mixing fluids, but is a bit more involved. There is a DIY on here on how to do the cooler line flush.
