Product Details

The B&M Holeshot 2400 Torque Converter is engineered to deliver improved acceleration and performance for GM automatic transmissions. Designed for street/strip applications, this converter features a 2400 RPM stall speed that provides the ideal balance between drivability and performance, allowing your engine to launch in its powerband for harder acceleration off the line.

Key Features:

  • Heavy-duty needle bearings for increased durability and extended service life
  • Race-proven technology and quality construction
  • Precision alloy steel impeller hub for superior strength
  • Copper furnace brazed impeller and turbine for maximum durability
  • Precision balanced on certified balance equipment to eliminate vibration
  • 2400 RPM stall speed optimized for street and strip performance

Applications:

  • GM TH400 transmissions (1965-1991)
  • GM TH350 transmissions (1968-1981)

This torque converter is ideal for performance street machines, weekend warriors, and bracket racing applications. The higher stall speed allows engines with performance camshafts and increased compression to operate more efficiently, resulting in quicker launches and improved quarter-mile times. B&M's precision manufacturing ensures reliable performance and exceptional quality.

My order was relieved before the date I expected it.

Quick and easy if you already have a part number.

I thought my order was going to take longer to ship and it surprised me after I called Autoplicity I thought another few days before it shipped and it arrived. The lowest price I found on my Mishimoto radiator was on Autoplicity.

good

Good

Very fast and easy item search and payment!

Great experience and the price was the best.

The best price for Hyperco coilover springs

Autoplicity has the cheapest prices around and fast shipping. I will do business with them again in the future.

No hassle ordering and fast quality shipping at a reasonable price

Simple and easy, more companies should work this way.

Ordering was easy. Will see how shipping aligns with expectations.

Item arrived promptly (4 days after order), price was good and item was as described.
