  What are your thoughts? The Chevy Blazer relaunch was an epic case of 'lunchbag letdown'. Jeep Wranglers and Ford Broncos stick out like a sore thumb. The AI photos do not look like a 'retro version', but shrunken Tahoes. Get away from the 'futuristic look'. I've seen two concepts. One had rectangular headlight like a Rivian and the other way to big should include dual round headlights like the early version. If not this would look OK At least it has GM styling (albeit the K2XX) A lot of the images floating around look like Bronco IIs or the current Bronco. Looking at the Broncos in my area (central Ontario, it seems to be a mix of 2 doors and 4 doors, 'mall rated' to ones that could go offroad. I'm sure a AT4 and AT4X RPOs could be outfitted similar to a Rubicon if the braintrust understood the whole offroad scene. Crosing my fingers that if it does see the light that the front air dam/bumper doesn't extend below the center line of the tire...

  And overpriced. I was in the Oshawa Truck Plant when they were being built. Very few. I could count on one hand how many I've seen since

  The 10L90 was used in high horsepower cars and SUVs (higher HP/torque version of 10L80). The HD trucks have the 10L1000 which was co-developed with Allison and is not related to the 10L80/90 which was co-developed with Ford. The 10L1000 replaced the 6L90 used with gas HD trucks in the current generation of the HD trucks.

  I have the 10L80 gas transmission. It rides at 145 or just a tad higher in the heat. Haven't towed with it yet. Both of my trailers are lightweight, 900 - 1500lbs empty, so I won't be pulling a whole lot of weight with it when I do pull them. But given this statement, "Ideal temps for automatic transmissions to do their job the best is 175-220F", what does that mean for our gasser trannies? Are they not operating at ideal temp? Or do those temps only apply to the 10L90 on the HD trucks?
