The roller clutch assembly and input sun gear were affected by the change. The following are only a few of the changes made to the 700-R4 up to 1993: 1982Ī new forward sprag clutch was being produced to replace the 700-R4 forward roller clutch. Some of the changes to the engineering design significantly influenced how the current 700-R4 transmission has evolved. Until 1993, the 700-R4 was revised many times. Many trucks and rear wheel drive automobiles such as the Corvette, Camaro, Jimmy, Suburban, 1/2 ton pickups, S15 and S10 trucks benefitted from a better transmission. The 700-R4 was used in automobiles between the periods of 1982 – 1993. Some of these changes are discussed in more detail in the next section. Overrun Clutch Hub – A raised area was added to tangs on hub Input Sun Gear – The sun gear shoulder was reduced, reduced overall heightĥ. Roller clutch assembly – The assembly was changed to Sprag freewheel with 26 elementsĤ. Outer Race – The lube hole positions were changed along with the inside diameterģ. Inner Race – A pressed on flange was addedĢ. The change affected several aspects of the transmission:ġ.

The longitudinal 700-R4 became an upgrade for many of the older, rear-wheel drive cars. A new model of forward clutch was being manufactured by May 1982, which replaced the roller clutch found on all THM 700r4 transmissions. A TV cable was used as a throttle position sensor for gear shifting. The model featured a lock-up torque convertor (view on Amazon) that allowed a connection which was direct and non-slip. The replacement 700r4 was a 4-speed automatic transmission was a bit longer in design, fully equipped with the overhead gear. The TH350 transmission was less durable and lacked an overdrive gear. The birth of the 700-R4 changed the market for automatic transmissions.

The first gear ratio of 3.06 was lower than normal, and provided off road torque and offline acceleration: 700R4 Transmission Ratios The 30% overdrive is the source of popular fuel economy. The 700-R4 lower first gear ratio is a source of superior performance for low speed. The 700-R4 is compatible with V8 and AMC 16 engines: 700R4 Transmission SpecsĤ speed, overdrive automatic transmissionġ982 – 2012 GMC, Buick, Chevrolet applications The transmission weighs about 155 lbs with around 16 bolts and offered a standard V8 90° metric bolt pattern with 4.3 V6. The 700-R4 was made manufactured with cast aluminum and measures about 23.4 inches long. One last distinction, the electronic version of the 700-R4 will not have a worm drive.
As mentioned, the three wheel drive model has shorter output shafts and adapter assemblies. Another primary distinction between the 700-R4 and the 4L60 is the rear output with four bolts. To identify the 700-R4, you should also look for the 16 bolts around the transfer case. The 4 wheel drive output shaft on the 700-R4 stuck out for about 3 inches, which is about 2 inches longer than the shaft in the TH350. The two wheel drive models will have a tail housing and the output shaft is longer.
