No, but if GM wants to write me a certificate for owning their junk transmission, I'll take it. Unlike you, I actually have experience in driving and maintaining the 4T65E.That smugness applies perfectly to your post.

Don't use what "some dude said on the internet will work", instead use "another dude's opinion".If you want to have issues with that transmission, use Low Viscosity fluid (like MaxLife), because some dude on Internet said "it will work".
Use Castrol TRANSMAX™ HIGH MILEAGE or TRANSMAX™ IMPORT MULTI-VEHICLE.
My wife has plenty of experience driving her Kia. Still that didn't make her capable of changing the timing belt, it was till on me, that I don't drive that car.Unlike you, I actually have experience in driving and maintaining the 4T65E.
Those fluids are in line with original transmission specifications (non-LV). Says GM (specific to that transmission when build, not a blanket statement 3 decades later) and Castrol (that makes that oil).Don't use what "some dude said on the internet will work", instead use "another dude's opinion".
Dex 6 didn't work well for my 97 Lesabre. It shifted harshly when it got hot. Drained and put in Dex3 and my transmission shifted perfectly. I know GM stated DEX 6 was the current replacement but I don't think it worked well with the older transmissions due to its viscosity. As others suggested, Max Life seems like a good option.
I'm doing a drain and fill, and a shift kit come spring. Transmission is a 2001. I was told by many to stay with the Dex III.I second what Lubener said. I had the same symptoms in my ‘99 Lesabre 4T65E during summer time and high temperatures. This was with Dexron IV which the original owner had used for their first ATF Service. I ended up using Mobil 1 ATF Synthetic (Dexron III Spec) when I did my own servicing and all of those symptoms cleared up beautifully. Ever since then, she shifts perfectly without any issues all year long in any temps. And unlike the original Dex 3 formula, Mobil1’s synthetic version does not have issues with shearing down. I avoided flushing and instead did a drain and fill with a new filter.
