Plainfield, Naperville, Bolingbrook, IL

The main function of a transmission torque converter is to transfer any rotating power from an engine or electric motor to a rotating driving load. Hence the importance of a properly working, as designed, per application, transmission torque converter.


Choosing A Transmission Torque Converter

Question: How do I choose a torque converter stall speed that is right for my application?

Answer:  Mathematics! Advertised stall speed will need to be at least 500 revolutions per minute (RPM) higher than the beginning of the powerband of your camshaft. All aftermarket camshafts are supplied with a cam card that states RPM range. If a camshaft states an revolutions per minute (RPM) range of 1500-6500, example, you would want to select a torque with a minimum of 2,000 RPM stall.  For a street car it is wise to also select a torque converter stall speed that is below the engine RPM at 65 MPH to prevent excessive heat build up. The exception would be a transmission/converter equipped with lock-up.

Question: What does the term “lock-up torque converter” mean?

Answer: This term refers to a converter that contains an internal lock-up piston or device, either friction or mechanical. Transmissions such as TH350C, 2004R, 4L60 (700R4), 4L60E, 4L80E, AOD, AODE/4R70W plus others, use these methods of eliminating slippage for an increase in fuel economy. Older transmissions such as the TH400, TH350, C6, C4 plus others did not incorporate these methods of lock-up. The only way to increase fuel efficiency in these types of converters is to change clearances, redirect fin angles and usually lower the actual stall speed.

Question: What application is the torque converter going to be used in?

Answer: Being a local transmission expert, we know how critical it is to know your torque converter. A performance torque converter should not compromise one aspect of car performance to achieve another. Before we install a converter we do a little investigation, proper investigation can improve initial takeoff, reduce a bogging effect, make sure of a customer’s happiness. Buyer’s these days very seldomly need to sacrifice one area of performance to gain in another. Hence the importance of proper investigation before any transmission torque converter installation. Do you have any torque converter related questions?
