    C6 Corvette ZR-1 Automatic runs 9.8@139

    Kind of detracts from the car IMO but makes it way more consistent in the 1/4 mile:

    That said, the owner of the World’s First Corvette ZR1 with an automatic transmission is a capable driver; however, he likes drag racing and wanted more consistency along with more power. Enter Redline Motorsports, one of the most respected late model tuning shops in the country. Howard Tanner of Redline welcomes unique projects and dropped the entire driveline out of this 2010 ZR1 to make the following mods: ported heads; ported blower; Comp Cam; American Racing 2 inch primary tube headers; Injector Dynamics 1000 injectors; upper and lower pulleys. The result, 723 rear wheel horsepower and 692 rear wheel torque.

    Now for the interesting part. Redline in conjunction with RPM Transmissions, also installed a special flywheel, torque converter and 4L60E overdrive automatic transmission to make this beast consistent. This is no small feat as there are no parts that are made for a ZR1 with an automatic trans, so everything had to be fabricated (flywheel, torque tube, etc). In addition, the crew at Redline had to get the ZR1s computer to send the appropriate messages to the 4L60E transmission’s computer to make it shift.

    This is one of if not the first Auto ZR1 its something more than a few owners want... You'd be amazed at the number of Zed6 auto's running around as well. Still not a bad kit and its using many OEM parts for fitment.
    We stay swingin...

    I like the performance but it just... doesn't feel right.

    i disagree with saying all cars that don't have 3 pedals are the same. i don't equate valve bodies with hydro electrically operated transmissions.
    would you say dogbox are boring automatics?

    I appreciate it but the car doesn't come with auto as an option. DCT is different.
