Make sure converter can rotate and has end-play. Converter must be free to move a minimum of 1/8", but not more than 3/16". If converter has no end-play, converter was installed improperly.
The torque converter does not need to be primed to fill it. There is no pump inside the torque converter. The pump in the transmission is driven by the impeller side of the torque converter, which is bolted to the crankshaft. If the crankshaft is turning, the pump is turning, too.
It is a big job though because the transmission will have to be removed so that the torque converter can be inspected and then replaced so if you're a beginner, it's not something you probably want to tackle.
The pump inside a torque converter is a type of centrifugal pump. As it spins, fluid is flung to the outside, much as the spin cycle of a washing machine flings water and clothes to the outside of the wash tub. As fluid is flung to the outside, a vacuum is created that draws more fluid in at the center.
Replacement of transmission fluid ordinarily does not include draining the torque converter. The procedure specified in many factory shop manuals for changing transmission fluid is merely to drain and clean the sump, and then install enough new fluid to replace what was drained.
If your converter has a drain valve, then you can refill it in the car. Assuming it's completely drained, rotate the torque converter until the valve is as horizontal as you can get it. Connect a two foot length of 3/8ths inch plastic tubing to a large plastic syringe and fill the syringe with fluid.
You can install it dry, but why would you? Nothing good happens when something hydraulic does not have fluid. Always put fluid in the convertor before installing.
Re: Certain steps to fill a rebuilt auto trans with fluidPut 4 quarts in the transmission when you get everything bolted in. After initial 4, start car for 3 second, and then shut off. Add 4 more quarts, then start car and leave it running. Continue adding until it shows full on the stick.
If you add too much transmission fluid, you will notice that it may foam, and that can bring about erratic gear shifting. Some other problems that may arise include oil starvation and transmission damage. Adding too much transmission fluid can also cause early failure and damage of parts as result of excess pressure.
Low-quality transmission fluid – or driving without transmission fluid altogether – can cause a number of problems such as transmission failure, gear slipping, a hard time shifting, and a few more issues.
If the transmission has been drained, you will need 4-12 quarts of fluid to fill it back up. Follow the vehicle service manual for the recommended type and amount of fluid to use. If the fluid is very low when it is checked, then add more fluid and look closely for any leaks.

However, manual transmission systems also have transmission fluid. Many vehicle owners will often choose to have a professional mechanic change the fluid for them, but this typically costs hundreds of dollars. The good news is that almost anyone can add transmission fluid, and you only need to know how to it properly.
Signs of Low Transmission Fluid
- Noises. If your transmission is working properly, you shouldn't hear any noise while you're driving as it should transition smoothly.
- Burning Smell. Any foul smell coming from your car should direct you to your nearest service center.
- Transmission Leaks.
- Slipping Gears.
How Much Does a Transmission Fluid Change Cost? The cost to have your fluid changed by a dealer, service center or independent mechanic ranges from $80 to $250. The average cost is around $100 for both automatic and manual transmissions.
A Toyota Corolla transmission flush also uses about 10 quarts of fluid to altogether clean and flush out the system.
It's also one of the chepest mods per performance you can buy! A higher stall speed torque converter DOES NOT add any horsepower. What it does, is move the engine rpms up higher at launch, so that you have more horsepower per mile per hour. Just like when you rev a stick shift car up higher for a quicker launch.
Repair shops will charge between $600 and $1000 to replace a torque converter. The torque converter itself is relatively inexpensive (between $150 and $350, depending on the vehicle), but 5-10 hours of labor is involved since the transmission must be removed in order to replace the torque converter.
Many problems can be caused by excessive friction which is usually a sign that a torque converter's needle bearings have become damaged. Faulty seals are also a prime suspect; they allow fluid to leak and become contaminated. Faulty clutch solenoids are also common causes of torque converter failures.
There are basically three ways a torque converter lockup clutch can fail: It can stay locked up, stalling the engine when the car is braked to a stop; it can never lock up, which shows up as an increase in fuel consumption and radiator temperature; or it can slip when engaged, allowing engine speed surges at a constant
Unless the transmission is in neutral or park, any motion of the turbine will move the vehicle. Instead of using air, the torque converter uses a liquid medium, which cannot be compressed – oil, otherwise known as transmission fluid. The spinning impeller pushes the oil against the turbine, causing it to spin.
Testing for Bad Torque ConvertersTurn the ignition key and start up the engine. Wait for a few minutes for the engine to warm up, then gently press the accelerator twice and rev up the engine. Once it returns to its idle state, press the brake pedal all the way and shift into drive.
Do All Automatic Cars Use a Torque Converter? No, not all cars known as “automatics” use a torque converter. That's because some transmissions, such as dual-clutch automatics, are mechanically closer to manual transmissions. All dual-clutch automatics use physical clutches instead of a torque converter.
In summary, a go kart torque converter is ideal for rough and off-road terrain where there are obstacles to be avoided or crossed and uphill driving may be required. But if your goal is to achieve the maximum speed to race in the pavement, a clutch is the better choice.
Will Changing Transmission Fluid Help Torque Converter Shudder? Yes, changing transmission fluid or performing a transmission flush will help fix most torque converter shudder problems. However, If you let your torque converter shudder for too long you might have to rebuild or replace it.
Mobil Type F ATF is an automatic transmission fluid which is made from high quality base oils with viscosity index improvers, antioxidants, anti-wear agents, defoamants and special additives to provide the controlled frictional characteristics of a Type F fluid in automatic transmission applications.

The E4OD and 4R100 transmission system holds almost 18 quarts of ATF, and you must waste a couple of quarts to be sure you get it all purged and replaced, so buy 20 quarts of MERCON ATF [For the 4R100, use MERCON V]. You may use either conventional or synthetic, as long as it meets the above requirements.
How to Drain Transmission Fluid – Step by Step Process
- Check Transmission Fluid Level.
- Warm up the Fluid.
- Gather Essential Equipment.
- Raise or Lift the Car.
- Locate Transmission Fluid Pan.
- Look for Leaks.
- Drain the Transmission Fluid.
- Examine the Fluid.
To check the fluid level, run the engine with the tranny in park, put your foot on the brake and run the shifter down to 1, stopping in each gear for a few seconds, then back to park.
The recommended transmission fluid is Dextron VI with a capacity of 11 Quarts. The transmission case had 16 bolts and a transfer case of aluminum. The transmission is pretty reliable and can handle torque up to around 350nm~, remember that this is only reported numbers and it can differ a bit.
