Transmission Gear Indicator Problems of Chevrolet Equinox

Car will not shift out of first gear. Goes up to 5000+rpms and will only go about 25 mph. Then it will randomly accelerate without you having any control of the speed. Check engine light came on and the gear indicator d flashed. Dealership cleared the code and could not replicate the actions. We drove the car about 30 miles and it happened again without the check engine light coming on. We videoed what happened. Dealership could not replicate again but still are working on it. They have called chevy in texas and there may be an ongoing transmission issue with this model. Gm tech assist sited similar issues having debris in transmission valve body. Debris will clear and get trapped in filter as designed. This occurred driving on a combination of highway, city streets,and country roads. Vehicle has 5100 miles to date.

Exited freeway on flyover, accelerating from 20-25mph on the downgrade to other freeway noticed that while speed had increased to 45-50mph, rpm's were high. Immediately pulled over, shifted to p, idled normal. Merged back in, again got high rpms, turned on hazard flashers, took off-ramp. Shifted to manual, gear indicator showed '2' and would not manually upshift to '3'. Pulled over, turned off car, waited 30 secs, restarted. Cautiously got back on frontage road, drove for 1 mile in 'd' at 30mph, seemed ok, got back on highway, gently accelerating up to 65mph. Drove the next 6 miles on highway, exited for neighborhood. Drove down primary boulevard at 35mph for 2 miles. Turned at 5mph to start accelerating up steep hill into neighborhood, immediately felt slippage and high-revs. Pulled over, waited for clear traffic, switched to manual shift, accelerated up hill in 1st, no problem; shifted to 2nd at 20mph, no problem; shifted to 3rd at 30mph, immediately high revs and slippage; switched back to 2nd; accel'd to 35mph in 2nd then shifted to 4th,engine lugged down but held and continued to accelerate and hold speed no problem. Shifted back to 3rd, started slipping and high revs again. Switched back to 2nd and drove last mile to house at 25mph. Drove uphill past house, turned around in neighbors driveway, noticed a loud 'whining' noise, like a tight fan belt or idler that is about to seize. Parked, whining noise continued. Revved engine a couple of times, noise went up/down with rpm. Turned off, went inside to research. Found that this is a known issue on older vehicles w/ 6t70/6t75 transmission. The 35r wave plate is known to shatter. Gm has issued "#14404: special coverage adjustment - transmission clutch wave plate - (Mar 3, 2015)" . Only covers older 2007-09 vehicles, this is a safety issue, should cover all vehicles w/these transmissions exhibiting this behavior.
