Why not pull the lower sensor on the side to drain it.

This is what I did. Make it a lot easier. The fill plug is still a pain to get to with the cooling line in the way.

Tip: whatever fluid you are wanting to switch to, pay attention to the specs kinematic viscosity - you do NOT want to go to anything much thicker than a Dex III ATF. Why? The syncros are NOT designed to work correctly with a thicker fluid. The only exception is if you are purely tracking the car; even then, you shouldn’t need it as the coolers do a good job at controlling temperatures.

Personally the Royal Purple Syncromax fluid works great in these transmissions, shifting feel is greatly improved over the OEM fluid especially at really low temps. |

GM and Tremec advise to use Dexron 3 spec. ATF for our TR-6060 box. BtW, the Vette's 2017 & up GS 7-Speed is also Tremec. Namely TR-6070. However, good results were found with the following fluisd as well. RP being the better "known" brand, while BG's Synchroshift2 is less known, but proved excellent results as well (Read test article - link below): ====================================== Royal Purple Synchromax http://www.royalpurpleconsumer.com/p...mission-fluid/ * BG SyncroShift 2 https://www.bgprod.com/catalog/drive...ncro-shift-ii/ Recent test https://motoiq.com/tested-bg-syncro-shift-ii-gear-oil/ ========================================= * |

I have been running Amsoil since February and am very glad I did. Transmission feels 10x better than it did before, plus the fluid offers better protection during track days.

Amsoil ATF for me. Its been better at the track for sure, I did my first 2 track days with OEM fluid and the last 3 track days with Amsoil ATF. I can say that I felt notchyness in the 3-4 gear change and ever since I changed to Amsoil ATF, no more notchyness

So far this is by far my favorite fluid in the TR6060. Very, ahem, fluid synchro engagement.
Normally we're on the same page, but the GM OEM fluid is terrible. Very notchy synchros to the point that in cold temps (50°F and below), I often couldn't get into 2nd gear on the first try. I firmly believe I have a transmission that's on the outer edge of the statistical bell-curve for synchro engagement, FWIW. I also tried AMSoil manual synchromesh, and it helped, but like Mountain mentioned, the cST is too high for the TR6060, so it isn't nearly as good as the Redline D4 ATF. -->TJay74: Royal Purple Synchromax and Redline D4 ATF have basically the same cST's at 40 and 100°C, FYI. 39/7.5 and 35/7.1 respectively. Also, read Tremec's datasheet for the TR-6060 (attached), they specify Dexron III ATF.

When it was time for me to change the fluid I looked at the local auto parts stores and had trouble finding Dex III. Most places had Dex IV or some other synthetic type trans fluid. I didn't see any Redline ATF anywhere but did find Royal Purple syncromax. I had tried the RP on other cars and T56 trans and felt no improvement. Once I swapped out the fluid in the 1LE it felt like a new car. All shifts are like butter, and the first 1-2 shift that was near impossible in the cold is smooth as could be, feels like a new trans.

I use BG fluids and Redline is a known racing fluid, either should be fine.
