manufacturer=General Motors
class=4-speed longitudinalautomatic transmission
predecessor=Turbo-Hydramatic
successor=
similar=A4LDUltradrive The 4L60-E (and similar 4L65-E) is a series ofautomatic transmission s from General Motors. Designed forlongitudinal engine configurations, the series includes 4 forward gears. It is an evolution of the Turbo-Hydramatic 700R4, originally produced in1982 .The 4L60-E and 4L65-E are built at
Toledo Transmission inToledo, Ohio and have also been built atRomulus Transmission inRomulus, Michigan andRamos Arizpe, Mexico .The two transmissions are differentiated mainly by the number of
pinion gear s in theirplanetary gear sets: The 4L60-E has four, while the heavy-duty 4L65-E has five. Other elements of the 4L60-E design were strengthened when the 4L65-E was introduced, but these were incorporated into the 4L60-E in 2002.Gear ratios:
4L60-E
The THM700 was renamed "4L60" (RPO M30) following the new General Motors naming convention, when the electronic version, 4L60-E, was phased in. This happened in
1993 for trucks, vans, and SUVs, and1994 for rear wheel drive passenger cars. 1993-95 production 4L60-Es look similar to non-electronic 4L60s (including the 700R4) with the absence of a governor and throttle valve cable; an electronic plug was positioned where the TV cable once stood. Around1996 , a bolt-onbell housing was phased in (along with a six-bolt tailhousing) when the transmission was bolted behind an inline four cylinder or the Vortec engine family.The 4L60-E is rated to handle up to 360 ft·lbf (488 N·m) of torque.

An updated 4L60-E, the 4L65-E (RPO M32), was phased in around the 2003 model year when coupled behind the 6.0 Vortec. Five-pinion planetaries, along with a higher capacity input housing and induction hardened input shaft assembly, were improved to withstand up to 380 ft·lbf (515 N·m) of torque. A new 300mm torque converter with improved higher-capacity internals was also introduced on select engine models.
