That's what I've been wondering, here I see people saying they are junk but AMP is pushing over 1400 to the tires through a stock 8 speed in their shop car. And they have built many at over 1000 that hold up and keep holding. I'm sure some have had issues but their are a lot that have been going for a very long time at really high power levels.

Most people don't want shifts like that. I agree, I prefer shifts where the ratio change is as instant as possible and it feels like a kick in the pants. But if I were a manufacturer and built transmissions how I like them, I wouldn't sell many cars. Not to mention...a shift like that is mechanically inefficient.

I still remember driving that camaro SS for the first time. I hadn’t driven the 6.2 8sp truck yet. The first time I go WOT I’m like “holy crap this is the same motor I have but the trans is incredible” I was so pissed I had the one year of the 6.2/6l80
8l90 has a much higher factory torque rating, and it doesn’t need to cut power during the shift. How GM managed to screw up solid gold hardware in the truck is laughable.

It does not feel like an old built 4l80 that is a violent shift. It’s tough to explain. Sure it’s fast, but it doesn’t feel like it’s doing damage, it feels like it’s super smooth and fast.

As far as I understand it’s still not amazing no matter how you tune it

I dont know sam, but you have to consider even if his iq rivals einstein, and people like justin from black bear was on par with forest gump, black bear would still do a better job just because of experience of tuning so many of them.

Well you understood wrong... the 8 spd in my truck is tuned and i really don’t know if it could be any better. The shifts are immediate and no lagging.

That’s the thing, the camaro doesn’t shift like that under normal driving. It’s only at WOT. They could easily tune the trucks like that and it would be fine.

Also, this is the same trans behind the ZO6, so you know it's rateed for at least 650/650.
