The '''4T60-E''' (and similar '''4T65-E''') is a series of [[automatic transmission]]s from [[General Motors Corporation|General Motors]]. Designed for [[transverse engine]] configurations, the series includes 4 forward gears. The 4Txx family is an evolution of the original [[Turbo-Hydramatic 125]] transverse automatic introduced in the early [[1970s]].

The 4T65 is built at [[Warren Transmission]] in [[Warren, Michigan]].

==4T60==
:''Main article: [[Turbo-Hydramatic 125]]''

The '''4T60''' was the transitional model from the old Hydramatic to the new electronically-controlled transverse family. Introduced in [[1983]] on the [[1984]] [[GM G platform (RWD)|G-bodies]], it was enhanced with electronic controls to become the '''4T60-E''' in [[1988]]. By the mid-[[1990s]], the 4T60-E was the transmission of choice in nearly every [[front-wheel drive]] GM vehicle. A heavy-duty '''4T60-E HD''' was introduced in [[1993]] for the [[supercharged]] [[GM 3800 engine]]. The 4T60-E was phased out in favor of the 4T65 beginning in [[1997]].

The 4T60 featured a 245 mm torque converter.

Applications:
* 4T60-E
** 1994–1996 [[Chevrolet Beretta]]/[[Chevrolet Corsica|Corsica]] V6 3.1 L

** 1992-1997 [[Pontiac Bonneville]] 3800 V6

==4T65-E==
The '''4T65-E''' was introduced to replace the 4T60-E in [[1997]]. The 4T65-E included a larger 258 mm torque converter and many other changes to improve reliability. It is able to handle vehicles up to 6500 lb (2948 kg) GVWR with up to 280 ft·lbf (380 N·m) of torque. A number of final drive ratios are available, with many distinct models. Starting in mid year 2000 models, all 4T65-E models received an upgraded valve body. Starting in 2003 the internal electronics were changed, and ratcheting sprags for input and 3rd gear were added.

Models:
* M15 — 245 mm (9.6 in) torque converter
* MN3 — 258 mm (10.2 in) torque converter
