When I bought my 06 6spd it had 36K the first thing I did was switch out the oil and transmission fluid. I usually use Amsoil oil so after reading it seemed like the consensus was the Amsoil transmission fluid was similar to the GM stuff so I decided to just go with Amsoil. What a mistake fast forward 6K my 3rd gear is somewhat notchy and shifting in general seems worse actually. Went to the local GM dealer and picked up the GM friction modified stuff last week and swapped out the Amsoil. Initial impression was its different but not the WOW I expected but a few miles later like 50-100 I am amazed at how smooth the car is shifting its unbelievable actually much much better then the Amsoil ever was. SO make the right choice the GM stuff is amazing!

If you really used Amsoil ATF, then you were using it in the wrong application. It's designed for use in automatics, hence the name, ATF - Automatic Transmission Fluid.

Did you use the universal ATF (wrong one) or the manual synchromesh trans fluid (correct one)?

Just so the verbage is clear for those who might be reading this.

Good to know so others won't make this mistake. We were just "guessing" which one was better in the other thread.

I went from GMSM to Amsoil MTF, no difference to report.

My 3rd gear grind was never that bad though, it was very intermittent.

How long ago?? Before I drained the OEM for Amsoil MTF I didn't have much of any notchy 3rd gear symptoms, but they started to develop some time over the 6K I had the Amsoil inside. I'm sure the Amsoil MTF is good fluid but it doesn't feel like it has the same amount of friction modifiers as the GM stuff.

Very interesting. I've always been using the GM stuff but read numerous reports of how the Amsoil was supposed to be the exact same thing. Your experience seems to indicate it's not. Anyway, the GM is a few bucks more but I've stuck with it since it's been great. No need to try another brand.

I may give the stuff a try. Last go around I ended up doing Acura stuff again, supposedly it had been reformatted from the 04 stuff that was in there to begin with. I don't have notchiness to begin with though.

that is correct.

Gurajit

so the third gear notchiness can be fixed with syncromesh then?

That's what everyone has been doing since '04.

What's the price difference between the ACDelco and the GM fluid?

Do they make the GM syncromesh for Automatics?

You can physically put it in an auto.........


The answer is NO. If you're having troubles with your auto, do a search, there's a ton of info on common auto problems and the fluid and electronics upgrades.

nfnsquared

No. Don't use the GMSM in an AT. A lot of AT folks like Amsoil. Read this thread for more info and how to do a 3 x 3 fluid change:

Amsoil MTF safe for our limited slip trannies? On the back of the bottle it says "Not for use in limited slip applications"...altho i ran amsoil MTF in my rsx that had a limited slip with no issues.
