My stock t-56 has 140k miles on it, with a Centerforce Stage 2 clutch and Fidanza aluminum flywheel. I'm changing the fluid on it tomorrow and i was wondering what you guys recommend filling it back up with.

I just drained Royal Purple ATF and refilled with Mobil 1 ATF. I honestly can not tell the difference. I did a lot of reading and that is why I chose the Mobil.

Everything you need to know about T56 fluids

if it every day driving/ some time racing, then any cheap regular dex 3 ( oreilly brand or advance auto part brand, valvoline ? is good.

if it racing all time and high rpm shift, I would use pennzoil syncromesh.

dexron 3 or better

I highly recommend dexron 3 ATF cause your trans has alot of miles on it. I put royal purple in mine when my trans had about 50 k miles and after awhile my 3rd gear would grind when i shift into 3rd gear. I drain the royal purple out and filled back up with ATF dexron 3 and grinding went away. A friend of mine tried pennzoil in his 02 camaro SS and was getting locked out of 4th gear i told him to put Stock dexron 3 ATF back in it that would eliminate his problems.

I'll get that dexron 3 for sure then. that sounds like a good idea as i sometimes get grinding from 1-2 and 2-3

This is the correct fluid to use.

Part number 88861800, I put that in google and clicked shopping.

I read about it here. https://ls1tech.com/forums/manual-tr...iii-atf-2.html

And found the quote below here: http://www.sandyblogs.com/techlink/2...dexron-vi.html

Are there different kinds of Dexron 3 ATF fluid? Or is that just it? lol

GM doesn't regulate any Dexron III additive package anymore (since 2006).
For automatic transmissions they recommend and regulate Dexron VI. What that means is you can buy Super Tech Dex VI from walmart and it will be the same as Dex VI in the GM bottle. THIS IS FOR AUTOMATIC TRANSMISSIONS ONLY.

You can't find anything any more that says Dexron III, it will say for use in vehicles previously serviced with Dexron III. Meaning it may vary from one brand to the next.

The correct fluid for a T56 is GM part #88861800 it's regulated by GM, and it replaces Dexron III in manual transmissions and transfer cases. This is not Dexron VI.

Sure you can put Dex/Merc, etc in it and it'll work fine.

pennzoil Syncromesh makes my transmission feel "notchy". I also heard from a few reputable transmission builders that I should not be using it in my transmission. I'm going to switch to some sort of DEXIII if I can find it.

Okay, so i will look around for the dexron 6, as its the new upgraded version of the dexron 3 haha

No, you don't want to use Dexron VI in a T56.

You can use GM part #88861800 manual trans fluid as a replacement for Dexron III. Or use a low quality Dex III compatable fluid from a parts store.

I have an RPM Stage 5 T-56. RPM told me Royal Purple Synchromax. Grant it the tranny is new and so are all my hydraulics, but shifts like butter.

I replaced the factory fill in my 01 T/A M6 with Mobil 1 ATF and the 1-2 shift became scratchy after starting on cold days. Drained it and replaced it with regular Dex III and it cured the condition.

106k mile stock t56, been in the 10's for a few years

nothing but cheap dexIII changed about once a year

what you use isnt as important as changing it often
