What transmission fluid goes in a 4L80E?
Transmission Fluid
| Manufacturer | Transmission Type | Transmission Fluid |
|---|---|---|
| CHEVROLET | 4L80E | DEXRON VI |
| ISUZU | 4L80E | DEXRON III |
| JAGUAR | 4L80E | DEXRON III |
| ROLLS ROYCE | 4L80E | DEXRON III |
Where is the Transmission Control Module on a 4L80E?
The 4L80E Transmission system is equipped with a computer called the Transmission Control Module (TCM), located in the left/rear passenger seat compartment which interprets, ana-lyzes and records electronic signals from sensors and switches located on the engine, brake pedal, and transmission.
What kind of oil pump does a transmission converter use?
Transmission Oil Pump. Transmission oil pumps provide fluid pressure for the transmission and torque converter. The valve body regulates, controls, and directs the flow of pressurized transmission fluid. Gear and rotor-type are considered fixed displacement pumps. Most pumps today are variable displacement.
How is the transmission pump attached to the engine?
Transmission pumps are driven directly from the engine through the torque converter. The torque converter housing is mechanically attached to the engine’s crankshaft causing the pump to operate whenever the engine is running.
How does a torque converter affect a transmission pump?
It saves energy by reducing output without affecting speed. Transmission pumps are driven directly from the engine through the torque converter. The torque converter housing is mechanically attached to the engine’s crankshaft causing the pump to operate whenever the engine is running.

What kind of fluid do you use on a 4L80E?
Dexron VI or synthetic is also fine but not necessary. In some very harsh conditions, the use of tractor transmission/hydraulic fluid can help fluid and clutch life. This fluid is clear and harder to see on the dipstick. It is equivalent to Caterpillar TO-4 fluid and is available in different viscosities.
Which is heavier a 4L60E or 4L80E?
The 4L80E will theoretically consume more HP than a 4L60E or other lighter duty transmission. It has a positive displacement pump as opposed to a variable displacement, it is heavier, has more rotating mass, more clutch drag, and on the surface would seem to “eat” HP.
Which is better TH400 or 4L80E transmission?
The 4L80E is a descendent of the proven TH400 transmission design. It is very rugged, has much more potential for power capacity than any other overdrive transmission on the market. It has better power flow for big power applications, much more clutch capacity and apply area than the 4L60E.
