To be honest, the OEM torque values were petty low. It didn't take much to break the 15mm bolts free. I just ran them down and snugged them down to where I know they wont back out.

Nice write up.
I'm not a fan of Royal Purple. Will a standard 75-90 synthetic work? Motul/Mobil1?

Well the GM fluid is a synthetic already. I can say usually I am a Mobile fan as well, but lately I have swapped our oils over to Castrol and this time went with RP MAX ATF for the 1LE transmission. It is a lot better than the GM OEM fluid, but there are still issue in the transmission that the dealer will be looking at in 2 weeks for me.

I saw the why and how, which was great, but what about the results after the change. Did it smooth out and meet your expectations?

http://www.royalpurpleconsumer.com/a..._Reference.pdf If you search the chart for recommended fluid to replace OEM fluid by GM PN 88861800 (from owner's manual), you see that they recommend Synchromax. It is specifically formulated for manual transmissions. On the description page for Synchromax: Quote:

I will have to go find some of that then. As you said, while the RP MAT ATF may not be what GM wants you to use, the immense improvement it made in shifting was a night and day difference in shifting. When I first got my 1LE and left for work on a 35° morning it was 6 miles before I could get the shifts to go without it sounding like a bag of marbles where in the transmission. The 1st to 2nd shift was so brutal and rough that I was surprised GM QC was ok with this kind of shifting effort. Neither my 2001 Formula Firebird with the M6 nor my 2008 Corvette with the M6 shifted like this, both were smooth as butter. |

Since both the 6th Gen SS 1LE and ZL1 use the same M6 (not sure about the non-1LE SS), you'll probably be okay with the Max ATF if you've already swapped it in, since Tremec calls for ATF. If not, I'd go with the Synchromax. Main reasons I chose Synchromax over Max ATF was (1) Synchromax was recommended for the GM fluid replacement in their cross-reference chart, and (2) disclaimers listed in the Max ATF spec sheet cited GM Dextron VI, the ATF that GM uses in their auto-trans. I figured that if GM will deny warranty claims for Max ATF in their auto transmissions, they're not likely to honor a claim using it in their manual ones either.

Do some Googling to learn more about manual vs auto transmissions and lubricants. That's what I did while researching this change. You will learn a lot more if you do the research yourself too. Let us know how your choice turns out. Good luck! --Cal Last edited by cwebster; 05-02-2017 at 06:24 PM. Reason: Clarify viscosity and additive differences. |

Will do man, I may end up changing it out this week on my days off just to try it. Not like it a costly change out, plus maybe it will flush some more junk out.

Thanks for the info. All this time I thought it was the boost. My biggest issue with my ZL1 is coming out of first gear doing the Launch Control. Do you have the same issue?

I believe the ZL1 and 1LE have different transmissions and clutch assemblies.
