LGX has been in production since 2016, only change in powertrain was 2020 with the inclusion of the A10 10L45 transmission to the v6. Otherwise same LGX 2016+ Current

resurrecting this thread because I haven't been on here in 3+ years and I'm looking to buy a 17-20 V6. Is the 2020 A10 trans any better than what's in the 17-19 models?

The A8 on 2016-2019 V6’s isn’t bad but it’s still apart of any A8 that could develop the shudder. Performance wise they’re practically the same, for daily driving the extra overdrive gears are nice.

The difference for the LT cars is the A8 is 8L45 variant and the A10 is 10L60 (not much information online regarding specs) but I’d imagine since the higher the number the more power it can withstand as is the case for 8L45, 8L90 for the SS. 10L80 for SS and 10L90 for ZL1

The number after the mounting direction designation letter (L: longitudinal, T: transverse) denotes the max torque capacity in 10 Nms, while the first number is obviously the number of forward gears. So, for example the 10L80 is a 10-speed longitudinal unit rated for 800 Nm (590 lb-ft) of torque.

By the way, the extra overdrive gear of the A10 is useless, the A8 has a better overall final gear ratio (its 8th gear has a final drive ratio of 1.8 vs the 10th gear's 1.81 on the A10).

The two actual advantages of the 10Lxx are slightly faster shifts due to better programming and the extra gear between the A8's fourth and fifth; this latter one helps a lot in drag racing where the A8 drops a bit too much rpm on the 4-5 shift.

I’m guessing with both tuned the only advantage then would be the extra gear?

I still wonder if they ever made a 10L45, I wonder why they moved from the 45 to 60 rating
