Synthetic ATF?
#1
![Question](https://ls1tech.com/forums/images/icons/icon5.gif)
I noticed the local auto parts store sells things like Mobile 1 synthetic ATF and B&M Trickshift fluid. I was wondering would this stuff be worth the switch? I have a new tranny pan on the way and of course I will have to change my fluid when I get it so I was looking to make an upgrade. Is synthetic ATF worth the extra money?
Thanks
Thanks

YES! I've been using the Amsoil ATF since 20k miles and love it. The fluid change brought my tranny temps down 20 degrees. Keep in mind that when you pull the pan and re-fill you are not replacing approx 10 quarts of fluid still in the TC and transmission.

I've been using Mobil Synthetic, almost as long as I've had the car and it works fine for me. Trans temp comes down a little and it will protect you if you over temp a little vs the regular stuff. Think of it as piece of mind in a bottle.

Royal Purple Max ATF works great also. I flushed the tranny at 82000 (found out the fluid at never been changed before I bought the car) before putting in the RP which did some good also, but doing that isn't required

We recommend to use only Dexron III trans fluid. We have found that using the synthetics such as Royal Purple and Redline the fluid is actually too slippery and causes slipping of the clutches which wears them.

Changing the tranny fluid too often in the A4's could cause them to slip. Besides, if you don't beat up your car, a fresh batch of fluid should last a long time.

I am reaching 13k miles on my 02 Z and havent had the fluid changed yet. I was looking at the synthetic fluids but as the post above noted that there will still be plenty of fluid in the tranny and converter. wont mixing the fluids just screw everything up?
