How do I identify a billet torque converter?
You will have to look at the area that connects the front of the TC to the flex plate. If there are little welded nubs on the front of it you have a stock TC. If they “flow”/look machined into the TC then its billet.
What does a smaller torque converter do?
Larger-diameter converters are usually more efficient and deliver less slippage, while smaller-diameter converters offer more stall speed and more slippage.
What does a billet torque converter do?
It’s responsible for transferring torque and horsepower from the engine to the transmission, and ultimately the wheels.
What is a lockup torque converter?
Lockup torque converters are a type of converter that has a clutch. The engagement of this clutch causes the engine to lock to the transmission input shaft thereby leading to a direct 1:1 drive ratio.
What kind of transmission does a Ford 4L80E have?
The 4L80E transmission is the advanced progeny of the legendary TurboHydramatic TH400 automatic transmission, and is based heavily on the 400 in both parts and strength, yet featuring an added overdrive gear, a lock-up torque converter and advanced electronic controls.
What kind of torque converter does GM 4L80 have?
The 4L80 features a 310 mm torque converter. As to length, this transmission is 26-1/4″ long. In 2006, GM superceded Dexron III as the recommended fill with Dexron VI, which is backwards compatible with the earlier versions. The transmission typically accepts a 6.3 quart fill.
How to identify a GM 4L80E longitudinal transmission?
With all GM longitudinal transmissions, it is far and away easiest to identify them by the amount of bolts on the transmission pan. Only the TH350 and TH400 share the same number of bolts. So if you count the bolts and get 17 you can be sure that you have identified the 4L80E transmission.
Where is the throttle position sensor on a 4L80E?
For increased power, depressing the accelerator to the floor will activate the throttle position sensor kick-down feature and will shift the transmission into one gear range lower than is selected on the gear range lever. The throttle position sensor is located on the fuel Injection pump. Figure 1. 4L80E Transmission.
