Is a bigger torque converter better?
Larger-diameter converters are usually more efficient and deliver less slippage, while smaller-diameter converters offer more stall speed and more slippage.
Do torque converters improve MPG?
Mpg will be significantly reduced since engine torque is not being multiplied during acceleration. A vehicle with a slipping one-way torque converter clutch will experience a 20 to 30% decreased fuel economy. A one-way torque converter clutch that does not release is a second type of torque converter failure.
What does a higher rpm torque converter do?
A higher stall torque converter will let your car accelerate better because the car will be taking off at the rpm range where it is making the most power.
How do I choose a torque converter?
Your focus in choosing a torque converter needs to be stall speed. Never put your vehicle to the test with hard power braking at wide-open-throttle sitting still to ascertain stall speed because you’re bound to do a certain amount of engine and transmission damage in the process.
What happens if stall converter is too small?
If converter stall speed is too low, the car will be lazy leaving the line; if too high, there’ll be excessive high-gear slippage—either case adds time to your e.t. Engine builders use car weight and dyno data to aid selection.
Can you daily drive with a stall converter?
However, a stall converter will affect your daily driving by lowering your fuel economy substantially. This makes it a poor option if you’re using the car for commuting. The reason that a stall converter boosts your acceleration is that it doesn’t allow the tires to break loose until you reach a higher RPM.
Can torque converter cause transmission problems?
A bad torque converter can damage a transmission. Bad torque convertors can lead to damage, overheating, friction, and transmission fluid degradation. If these problems continue, it can cause even more damage to transmission.
Does torque converter affect acceleration?
By redirecting fluid flow, the converter multiplies the torque produced by the engine enough to propel a vehicle down the road. Most converters multiply torque by a ratio of at least 2:1, improving vehicle acceleration substantially.
Will a torque converter add horsepower?
You will not be gaining any horsepower, rather you will be recovering horsepower that would have been normally lost with your stock TC. In addition, a stronger TC will have a higher stall speed. This will allow better launches when you are brake torquing or flashing the TC.
What happens if your stall converter is too high?
If converter stall speed is too low, the car will be lazy leaving the line; if too high, there’ll be excessive high-gear slippage—either case adds time to your e.t. Engine builders use car weight and dyno data to aid selection. The converter is also matched to the transmission’s gear ratios.
Will a new torque converter give me more power?
You will not be gaining any horsepower, rather you will be recovering horsepower that would have been normally lost with your stock TC. In addition, a stronger TC will have a higher stall speed.
What is the best stall speed for towing?
If your motor generates more power in the lower RPM range, you’ll want to select a converter that stalls at the beginning of that RPM range. If you use your vehicle for towing, make sure your torque is around 1800 RPMs.
Can you daily drive a high stall converter?
Can You Daily Drive High Stall Torque Converter? – YouTube
What is a good stall speed for the street?
In general, the desired stall speed should be 500-700 RPM below the engine RPM at peak torque. This ensures a margin for application for the torque converter to take off. You don’t want to have to floor your gas pedal and wait a few seconds for your vehicle to move.
What is a good street stall converter?
For mild performance cars with something like a 350 HP engine, a 2,200 – 2,400 stall is about right. The basic rule of thumb is; if your engine “comes alive” at say, 3,500 RPM, then you want a stall converter with about 3,500 of stall to it.
Do I need to fill torque converter before installing?
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.
What are the signs of a failing torque converter?
6 Signs of a Failing Torque Converter
- Loss of Acceleration.
- Slipping Between Gears.
- Vehicle Won’t Shift at All.
- Transmission is Overheating.
- Transmission Fluid Leak.
- Bad Transmission Fluid.
At what RPM does a torque converter engage?
Factory torque converters utilize around 2,000 to 2,200 rpm stall in most diesels, and they’re that way for a reason, as most factory ¾-ton pickup-sized engines spin about 3,000 to 3,500 rpm and can create full boost by about 2,000 rpm.

What does a 3500 stall converter do?
If the converter was a 3,500 RPM stall, then it would be at approximately 3,500 RPM in which it forces the tires to break loose.
