Rebuilt torque converter ford

Make sure that when you talk to your Transtar sales rep, you give them both codes as well as the complete vehicle information to ensure you receive the correct product. Transtar does not publish an industry part number interchange, but you can order a Transtar torque converter by using almost any competitors part number.

Talk to your Transtar sales rep to make sure you are getting the correct part on your order. Often the torque converter is not the root cause. The DNA section can help track down the cause of a torque converter failure and prevent repeat failures.

Used and quality-inspected parts are sold as-is with no warranty. Product should be thoroughly inspected prior to installation. Any manufacturer, third-party, extended warranties, or limited lifetime warranties, should be handled through the manufacturer.

As the diameter of a torque converter decreases, stall speed goes higher, which is why race converters are generally smaller than street converters.

Transmission parts supply houses generally sell stock torque converters with 1, to 1,rpm stall speeds. These converters are off-the-shelf dead-stock pieces that are not always designed and constructed for performance purposes. Aftermarket high-performance torque converters are designed and constructed to take additional punishment, with features such as:. Stock torque converters come in sizes around 11 to 13 inches in diameter with stall speeds around 1, to 1, rpm.

This RPM range is where you want a street engine to begin applying torque. You want a higher stall speed on a street engine when the application of power is expected to be in the 2, to 2,rpm range.

For example, if you have a hot cam and an aggressive induction system along with a rough idle around 1, to 1, rpm, you want a higher stall speed for better traffic light idle, higher in-gear quality, and proper application of power as RPM increases. You want the torque converter to take hold stall at 2, to 2, rpm as the engine begins to make power. In other words, you want the torque converter to slip until RPM reaches the 2, to 2,rpm range. The type of torque converter you choose depends upon how you intend to drive the vehicle.

Street cruisers do not need high-performance, high-stall torque converters. Stock engines normally make peak torque around 2, to 3, rpm, with peak horsepower coming in around 5, rpm. Highperformance engines normally make peak torque around 3, rpm, with peak horsepower rolling in around 6, to 6, rpm.

High-performance engines begin to make power at a higher RPM, which is where you want a torque converter to take hold with a higher stall speed. If you run a high-stall converter with a stock engine, slippage occurs until your engine reaches the high stall speed. This makes normal driving difficult. Older torque converters have drain plugs for servicing, needed every 30, miles or 3 years. Never completely drain the torque converter due to the risk of pump cavitation.

It must line up with a corresponding hole in the flexplate or you wind up distorting the flexplate. Slippage and high stall speeds affect upshifts.

At 5, rpm, the engine speed drops by 3, rpm with each upshift. This costs you precious time on the quarter-mile or at the traffic light. This is known as a tight or loose converter.

Much of the general technology is rooted in fluid dynamics and how fluid behaves under given conditions. And this fact alone helps determine your quarter-mile times and the way your Ford behaves on the open road.
