Q & A

What's in the Box

Races are won or lost at the starting line, so make sure you come out ahead with a High Performance Turbo 400 Torque Converter. Whether you are looking for a street, strip, racing, or just plain heavy duty converter, these units will deliver lasting performance in your GM TH400 (with 11-1/2" bolt circle). With features like welded internals, oversized bearings, and hardened hubs, you can rest assured that these torque converters are of the highest quality possible.

  • 2200-2600 stall - 12" diameter 
  • 1965-'91 GM Turbo 400 - 11-1/2" bolt circle

All stall ranges will vary depending on the engine setup, vehicle weight, and gear ratios.

High stall converters are designed for S/B or B/B cars with performance camshafts and high ratio rear end gears (3.55-3.73 minimum).

Made in the U.S.A.

Notes

  1. All advertised stall ranges will vary depending on your engine's setup and the weight of your vehicle. If your car is heavier than the recommendation, the stall speed will be higher. If the car is lighter, stall speed will be at a lower RPM.

Specs

  • Hardened Hub
    • Increased durability through the allowance of tighter tolerances and clean fit with transmission seals
  • Welded Impeller
    • Stronger pump fins to maintain stall speed over the life of the converter
  • Heavy-Duty Stators
    • Heat treated fins, sprag and race designed to efficiently handle high power loads
    • Stator fins are formed, not cut - cut stators can cause severe slippage
    • Rapidly dissipates heat - more power to the wheels
  • Welded Turbines
    • Pre-stressed before welding - more rigid construction
    • Heat treated splines
  • Aluminum Spacers
    • Incorporates aircraft quality aluminum spacers which handle higher loads than fiber spacers found in standard converters
  • Oversized Bearings
    • High strength stamped bearings absorb shock and extreme abuse better than standard waffle bearings
  • High Tech Welds
    • Positive-charged, military grade MIG welds for complete fusion of the metal

Part number 109614 is a 2200-2600 stall torque converter for the fixed pitch transmission and is a fixed pitch converter. If your transmission has a replaceable filter element then you have the more common and desirable fixed pitch version. The variable pitch had a washable filter with attached neck and these were from 1965-mid 67 and not the most desirable version. The fixed version was available on a limited basis later in that time frame and from then on. The fixed version also had the VIN stamped on the case. TH400’s had three different tail shaft lengths and two different output shafts and neither was specific to a year or model. For clarification the listing should read 65-91 fixed pitch converter applications.

Will the pt#109614 fit a dual pattern flex-plate on a Buick 350 engine with a th-400 cadillac transmission ? If it does what size converter bolts do I order with it?
