700-R4（4L60）性能传输

Introduced in 1982, the 4-speed Overdrive GM 700-R4 transmission — also known as the4L60.- 仍然是街道/条带性能应用的热门选择。Most of the unit’s internal components are shared with the ’93-later 4L60-E, which was regularly improved/revised up through 2010. This means many of the Sonnax parts developed to improve 4L60-E performance and durability also can be used in the 700-R4.

作为一点背景，700-R4是通过许多缩略语所述的GM涡轮湿润单元，包括Th700R4，700R4，THM700R4和700R4。较少常见的是700-R4是与GM 4L60完全相同的传输。OEM在1989年简单地改变了该单位的官方名称 - 介绍了700 r4后的大约八年。这个新的命名公约继续延续4速，电子控制系列单位指定为乐动体育app下载LDsport ,4L65-E,4L70-E.and 4L75-E. The valve body itself is the biggest difference between these two types of 4-speeds. The 700-R4 has a cast iron valve body controlled by throttle cable and mechanical governor determining shift points. The 4L60-E has an aluminum valve body with computer-controlled solenoids actuating the shifts.

Benefits of the 700-R4 are many. A steep 1^st齿轮使重型车辆移动并制作出巨大的倦怠，而过度的4^thGear delivers lower-cruise RPM. Compared to other transmissions, the 700-R4 is a compact unit, is familiar to many and usually simple to install without a computer. For those looking to improve 700-R4 torque capacity, a common question is: how much horsepower can the 700-R4 handle? While it’s an older transmission, the 700-R4 is no slouch and still very capable in many applications up to about 750HP. The following Sonnax transmission components are recommended for maximizing durability in any build.

微调转变感觉

700-R4（4L60）离合器饲料孔钻孔微调换档感觉

钻孔离合器饲料孔是一种探索的方法，可以减少离合器接合时间和坚固的移位感。这有助于其他懒惰转换的传输，勤奋的商业应用或修改的单位进行绩效。但是，使用错误的尺寸钻孔是非常容易的，并产生严厉的换档。如果您想在700-R4或其他GM变速箱中放大馈影，请学习如何通过在我们的指南中挑选正确的钻头尺寸来避免问题Drilling Orifices the Smart Way. A good starting point when tuning transmissions for shorter shifts is to increase clutch feed holes sizes by 20% area. For even firmer shifts or with high-stall converters that tend to dampen shifts, go up to 50% larger.

进一步微调换档特性与700 r4的旧学校，机械控制是具有挑战性的，特别是随着那里的各种OE核心校准。具有电子控制的更现代化的4L60-E系列单元将支持更容易，通过售后市场调整技术进行更容易，更可预测的调整。如果您真的希望以现代编程和更大的马力潜力的所有优点来表现下一个级别，请查看这些Sonnax build charts for 4L60-E series transmissions.
