Adjusting the TV cable is a relatively easy process that allows you to change the shift points of your vehicle. The 2004R is a bit more aggressive with a ratio of .67:1. 2. The shift from 3.06 ratio (1st Gear) to 1.63 ratio (2nd Gear) is a dramatic RPM drop that causes performance engines to fall out of their power band. The 700R4 is a 4 speed automatic transmission, with a 30% overdrive in 4th gear. Twelve speedometer driven gears are available for the 700R4 / 4L60 transmissions to calibrate the speedometer with various axle ratios and tire diameters. Ideally I would switch to 3.42's but I have a 4 series carrier and can only drop to 3.73's. 00. While it is not computer controlled, it does use a TV Cable, which acts like a throttle position sensor to control when and how hard it shifts.

It was much improved by the 1988 model year. The steepest first gear ratio of any four-speed automatic (3.06) belongs to the GM 4L60 (700-R4)/4L60-E family of transmissions. Axle Ratio: Tire Height: Driven Gear Teeth: 4.56: 33: 42: 4.56: 35: 39: 4.10: 26: 45 will work, but will read about 3 MPH fast at 50 MPH. My rear gears are 3.08. The thing with fluid capacity is that it is not constant for every application. This transmission had a lower first gear ratio, which was good for performance at low vehicle speeds, while the 30% overdrive provided significant fuel economy improvement. You will need to shorten the driveshaft regardless of whether or not you have the Corvette version or the standard length 700R4. As is expected with all new system, especially with such a major re-design, some design issues were present with the original release.
