TH700 Chevy Getriebe: 4L60E anstatt R4

In 1993, the designation of the 700R-4 changed to 4L60. A later version of this transmission, the 4L60E, is an electronically controlled variation, utilizing a reluctor ring (similar to that in an ABS application) and magnetic pickup, together called the Vehicle Speed Sensor (VSS). The transmission requires this feedback to map the shift points. In 1998 the 4L60E was redesigned to include a removable bellhousing and a shorter main case length, along with a 6-bolt tailshaft housing as opposed to the 4-bolt earlier configuration.
