so i guess this tranny isn't made to be smooth.

 

I don't know Dallas' zip code off hand, so here you go:

The fluid that technically goes in our trans is the D4 ATF. People also run the MTF.

Also, if there's not a dealer near you (which I kind of doubt), another fluid I had fantastic results with was GM or Penzoil Synchromesh. In fact, I think it might've been slightly better feeling than the Redline, but I can't justify dumping out $40 worth of fluid to go back. It'll be what goes in for the next change. You can usually find the synchromesh at your local Autozone, Pepboys, what have you.

Also, no, these transmissions aren't meant to be smooth, at least from my experience.

 

I need to change my transmission fluid on my 06 V6. I don't think I need the most expensive stuff. What would you suggest? Mine is an auto and doesn't seem to have any issues. I bought the car at 55K and now has a little over 70K. I have no idea when the last transmission fluid change occurred.

I need to change the oil too so I thought I would do it together.

I have changed oil in cars before, but are their any best practices for trans. fluid changing as this will be my first time?

 

I switched to AMSOIL Synthetic ATF a couple months ago. Shifts nice & smooth. Now if I can find someone who wants to trade their MGW for my Hurst...

 

Sorry, just saw this. Transmission fluid should be checked every 15k miles. For manual, it should be changed at 105k, and for automatic, at 150K. Click here to check out the 2010 Maintenance Schedule.

My shifts were rough at the beginning too, but got much smoother with time and miles driven, plus I changed the fluid to Mobil 1 that seemed to help a bit too...

 

I switched to a blend of 1 Bottle of Royal Purple Synchromax and 2.2 bottles of Mobil 1 ATF and it has made all the difference in the world. Best mod I have done to my 08' Bullitt.

 

Getting a short through shifter helps too. Mine is 100% better just from this alone...
