The torque converter is one of the numerous car problems that car owners often experience. For daily driving I suggest a 3800 and 3. Originally started by Top Fuel racer, Mike Strasburg at B&J Transmissions, it is now run by Steve Graves and family. The torque converter had entirely too high of a stall speed, and it wasn’t allowing the Red Dragon to reach its full potential with our goals, so it was time for a change. How It Works: Automatic transmissions. Higher stall speeds become necessary when horsepower and torque happen at higher rpm ranges. I would also change the single plane intake for an Edelbrock RPM air gap. If you use a converter designed for a larger engine your stall speed will be lower than the manufacturer's description. Here are the conditions specs: 1995 Corolla DX. The AWD Lexus IS is notorious for this. The smell of burnt paper while driving, especially when changing gears, might be a sign that the clutch facing is burning off as the clutch slips. The transmission will shift through neutral first, relieving any preload. One "fan," called the impeller, is connected to the engine (together with the front cover, it forms the outer shell of the converter). Converters are just like cams, if you want top notch performance, it will have to be custom made for your car. A 3500 stall converter will normally stall about 2500 to 2600 in low gear and 3200 to 3300 in high gear. Remember, the ratio is still a factor of the engine torque in the relevant range of the torque converter stall speed, i. The dealer claims the normal operation of the torque converter is what caused the car to stall. Get in the car and put on your seatbelt. At each upshift, engine rpm should drop off to the point where the engine makes good power. How driving through water affects your car. Finally, towing the car with the drive wheels (front or back, depending on the car) still on the road can damage a transmission as well. Beware of the cautions when testing the converter. It is a common misconception that it is impossible to stall an automatic car. All converters also have a built-in fluid dampening feature. Also, "loose" and "tight" are subjective like driveability. My thoughts are that it should probably flash to around 4500-5000 rpms.
