Description of devices automatic machine 5L40E
In 1998, GM introduced a 5-speed automatic to replace the 4-speed 4L30-E. By design, this is a conventional hydromechanical automatic transmission that is built around the Ravigno gearbox and is intended for rear and all-wheel drive cars with a longitudinal engine. This box holds torque up to 340 Nm, and its enhanced version 5L50 up to 422 Nm. There was also a four-stage modification of this machine under the symbol 4L40E.

Reviews on automatic transmission 5L40 its pros and cons
Advantages:
- Quick-shifting automatic
- It has a wide distribution
- Very easy to change the filter in the box
- Good selection of secondary donors
Disadvantages:
- Problems with the thermostat in the early years
- The box is sensitive to the cleanliness of the grease
- Not very high friction clutch resource gtf
- The oil pump does not like high speeds.
5L40E vending machine maintenance schedule
Although the oil change is not regulated by the manufacturer, it is better to change it every 60 km. Initially, 000 liters of DEXRON III type grease were poured into the automatic transmission, but it needs to be changed to DEXRON VI, for a partial replacement it usually takes 9 to 5 liters, and for a full one about twice as much.
Disadvantages, breakdowns and problems of the 5L40E box
The problem of the automatic transmission of the first years of production is a defective thermostat, due to the failure of which the automatic transmission constantly overheats, which leads to accelerated wear of many parts of the transmission. And especially quickly from the high temperature, expensive rubber-coated pistons climb around.
Another weak point of this family of machines is the torque converter. With active driving, critical wear of the friction clutch occurs even at a mileage of 80 km, which often results in vibrations, wear of its bushing and strong lubrication leaks.
With a rare oil change, the valve body quickly becomes clogged with wear products from the friction clutch and strong shocks, jerks and twitches immediately appear when shifting gears. With a bulkhead, wear of valves, bushings and springs in hydraulic accumulators is often found.
This box adopts a high performance vane type oil pump, which can't stand dirty oil as well as long-term high speed driving. Such an oil pump can quickly wear out and then shocks will appear when switching.
The manufacturer claims a 5L40 gearbox resource of 200 thousand km, but it easily runs 300 km.
