You may be wondering what is a 700r4 transmission anyway? Well, this kind of transmission was first developed in the year 1982. The 700r4, along with the 200-R4 transmission, came out to successfully take over the TH350 transmission that year. The TH350 was a highly popular 3-gear transmission that was not equipped with the last overdrive gear. The 700r4 came with surprising capabilities and proved to be a big upgrade that also came with additional gear. The 1st and 2nd gear became longer, and the transmission case got considerably extended than the regular length. A lot of individuals became fans of the 700r4 because of its incredible durability. Finding replacement parts and other kits for this transmission also became quite easy and manageable. The 700r4 transmission that was launched initially was not electronically controllable still; it could be controlled with the help of a hydraulic pressure mechanism. For this, a TV cable that acted as a throttle position sensor was used to control the gear shifting. It was only in 1991 that the 700r4 transmission was replaced by the more popular 4L60 transmission.
