When installing the converter onto the transmission, please pour approximately one quart of ATF (automatic transmission fluid) into the converter before installing into the transmission. Using a light grease, coat the transmission seal, front pump bushing, and converter neck.
Do you have to fill torque converter with fluid?
No you do not have to pre fill a torque converter prior to installing it. Since you have to remove the automatic transmission to replace the torque converter, you also have to drain the ATF that’s in the transmission so it doesn’t leak out the tail shaft and speed sensor installation hole.
Is there transmission fluid in the torque converter?
A torque converter is a doughnut-shaped internal engine component directly attached between the engine and transmission. … The space inside the torque converter is normally full of transmission fluid, which helps in transferring power generated from the engine to the transmission.
How do I check the fluid level in my torque converter?
Another method of checking the fluid is to turn off the engine and immediately check the level. This will stop the agitation and give an accurate level (no agitation) before the fluid in the torque converter has had a chance to drain back into the pan area which would give a false-high reading.

How much fluid does a TH400 torque converter hold?
You can expect to use between 11 and 12 quarts of fluid in the stock version.
What fluid is in a torque converter?
Instead of using air, the torque converter uses a liquid medium, which cannot be compressed – oil, otherwise known as transmission fluid.
Does a torque converter spin in park?
It remains stationary when the transmission is in park or neutral; however it spins opposite to the engine rotation when hydraulic pressure (or wind) is provided. … Because air would eventually compress when forced to move at a higher speed, the torque converter is sealed and filled with transmission fluid.
Can a bad torque converter cause rough idle?
Rough idling is another common symptom of a bad torque converter. If you feel that your idle is a bit jumpy and sometimes too low and sometimes too high, it could be a torque converter problem.
What type of fluid flow is present in the torque converter during maximum torque multiplication?
There are two types of fluid flow inside the torque converter. The first is the vortex flow, and the second being the rotary flow. In the below picture, the vortex flow is a spiraling flow which continues as long as there is a difference in speed between the impeller and the turbine.
Can you overfill a torque converter?
This can be anywhere from three to ten quarts. Don’t worry about overfilling it; any excess will flow into the transmission.
Can you fill transmission fluid through dipstick?
The transmission itself is full of fluid that keeps everything running smoothly. … To avoid this, you can use the transmission fluid dipstick to monitor the level of fluid inside of the automatic transmission and, if necessary, add fluid to the transmission.
What transmission fluid does a TH400 take?
It might appear that Dexron VI would therefore be backwards compatible as far back as the older TH350 and TH400 transmissions. The reality is that Dex VI is best only for newer vehicles.
How much transmission fluid does a TH350 take?
A TH350 with stock pan and converter will take between 10 and 11 quarts if completely dry. Once you get 8 or 9 quarts in, start checking the dipstick.
How much fluid does a C4 hold?
Fluid Servicing Facts
With the torque converter and pan empty, the C4 requires eight quarts of fluid. Add five quarts first, then check the dipstick reading with the car on a level surface.
