The 4L60E is rated to handle up to 360 ft⋅lb (490 N⋅m) of torque. Beginning in 1998 a new 300mm torque converter with improved higher-capacity internals, 300mm style input shaft, and 300mm style pump was also introduced on models coupled to a Gen III Small Block. In 1996, a bolt-on bell housing was phased in (along with a six-bolt tailhousing) for S-10 Trucks and S-10 Blazers and beginning in 1998 for all other applications. This happened in 1993 for trucks, vans, and SUVs, and 1994 for rear wheel drive passenger cars. The TH700R4 was renamed "4L60" ( RPO MD8) following the new General Motors naming convention when the electronic version, 4L60E (RPO M30), was phased in as the 4L60 was being phased out. 4L65E/4L70E uses a 300mm input shaft and converter designed for LS applications only. 4L60E's uses a 298mm input shaft for non LS and a 300mm input shaft for LS applications. They also have different input shafts and torque converters. The 4L65E/70E uses a 7" depth bell and 7 bolts. 4L60E uses a 6.5" depth bell with 6 bolts for non gen 3 LS applications and a 7" depth bell with 7 bolts for LS applications. The 4L65E shares the same exterior parts but have stronger internals such as 5 pinion planets compared to 4 in the 4L60E. The two transmissions cannot be differentiated from the outside. The 4L60E and 4L65E are built at Toledo Transmission in Toledo, Ohio and have also been built at Romulus Transmission in Romulus, Michigan and Ramos Arizpe, Mexico. The 4L60E is the electronically commanded evolution of the Turbo-Hydramatic 700R4, originally produced in 1982.
