C8 Dual-Clutch is getting new programming

C8 Dual-Clutch is getting new programming

November 15, 2019 Off By Mike Vietro

During the major magazine reviews, the only major complaint reviewers had was that the new eight-speed Tremec Dual-Clutch automatic was a bit clumsy and not as responsive as it could be. In road and track’s Performance Car of the Year testing, they wrote that “the gearbox was the weakest component in the pre-production C8 Stingray we had on hand” and “part of why the Corvette didn’t win.”

Most of the complaints were not in automatic mode, but rather in the paddle shift mode, where too often testers found themselves running into the rev limiter, or having downshifts denied after a paddle pull.

The good news for us consumers is that, the C8 they had to test was not a finished product. There’s been development work since reviewers got the car, and that work will continue for the foreseeable future to get it just right.

According to Glen Hoeflinn, controls program manager for the DCT, the humpy-bumpy shifts reviewers got here and there all got refined out. “It’s in final refinement, and then it’s in final checks and looking what we’re doing and making sure that it’s behaving exactly [how] we want.”

Refining and programming is not as simple as it may sound, as the new C8 is not a track only car with just one mode. The transmission has different automatic shift strategies for the various drive modes, which adapt in real time. The more aggressive, the more spirited you drive, the more aggressive the transmission is going to respond, but as you start to relax, the car’s going to start to relax.

Motor Trend reported horsepower numbers

As we reported a few weeks back, Motor Trend published some horsepower numbers for the C8 that we said seemed to be a bit off. Well they have come out and said they messed up. They said “key parameters were botched, but the C8’s still plenty powerful”. It gets very technical as to what happened, with things like “road-load” settings, but the real big problem was that the Dyno was set to all-wheel mode! These factors make the dyno believe the Corvette’s powertrain was overcoming way more inertia than it really was, which led to the inflated results.

Featured Car of the Week

1966 Beautiful & Rare Color Combo L36

1966 black corvette l36 convertible coming 1

What Mike likes about this car:
“To date, black with red interior is still one of the most sought-after color combinations of any year Corvette dating back to 1954.  In fact, a black 1954 with red interior could possibly be worth double what a white 54 is worth in most people’s opinion. When you get to the stingray Corvettes from 1963 to 1967 the combination is even more striking. Add to it a matching number big block engine and you have what most would consider the pinnacle of stingray production possibilities.  This is a car you can have fun with and enjoy without having to worry about driving it on the streets. She’s no trailer queen but she’s ready for a night on the town!!!

Happy Throttling!
