We design the Allison converter components here at Goerend Transmission, and also manufacture them from start to finish using our eight in-house CNC machines. This ensures accurate dimensions that work with your transmission. This also means you are communicating directly to the manufacturer, which is very rare in this industry, and allows us to answer all questions quickly and accurately. We build our billet front covers and clutch pistons from steel forgings, greatly reducing any chance of porosity. Our stators are designed to rotate better when going into coupling mode, as well as assist torque multiplication and are guaranteed to never break. Our patented internal design insures that the torque converter clutch will lock up on the computer and valve body’s signal. Our knowledge, equipment, and patented converter components allow us to build the converter to match your needs, no matter if you use it as a daily driver or a dedicated race truck.

The chart below shows the K factor and torque ratios as related to our converter stalls. Below is how to interpret the K factor and torque ratio numbers. The lower the K factor, the better the converter will couple. The higher the K factor, the easier the converter will spool up. The torque ratio is the torque multiplication number. For example, if a converter has a torque ratio of 1.85, then for every 100 lbs of input torque, the converter will deliver 185 lbs of output torque. This is at a converter stall or speed ratio of 0. This ratio will go down as the speed ratio goes up. Engine modifications will directly affect stall speed. Stall speeds listed below are approximate & will vary based on engine torque.

    Smooth and Solid

    Posted by Unknown on Apr 13th 2017

    Was recommended the X converter by Scott at SDP. I love this converter the lockup is so smooth almost cant tell when it does even racing i cant feel the lockup happen. A good smooth and solid lockup makes a big difference on the life of hard parts. was on a built LBZ making just under 700hp with just a built trans and this converter. No billet parts in the trans.

    Awesome Converter!

    Posted by Nathan McCutchen on Apr 9th 2017

    I absolutely love my "R" converter. Paired to my SDP built transmission it is awesome. Lockup is nice and smooth but firm. Not at all harsh like some of the competitors. I can really feel how it will help prolong the life of a built transmission! Would not hesitate to recommend Scott or Goerend to anyone!

    "R" converter on LBZ

    Posted by Joe Martinez on Mar 12th 2017

    I had Mike at Inglewood Transmission build my Trans 17 months ago. Mike recommended the "R" converter for my application, welding rig with stock fuel and air, so she's right around 11k lbs everyday. The transmission as a whole performs flawlessly, smooth crisp shifts and surprisingly smooth TC lock up under full power... EVERY TIME! You can't put a price on reliability when you depend on your rig to make a living... That's why I went with the best!

    Billet X converter

    Posted by Cody Bradley on Mar 7th 2017

    I purchased the Goerend X converter with the billet stator to be paired along with a built trans for my 07 LBZ Duramax. I couldn't be happier. This converter locks up great wither I'm Wot on my built trans race tune or pulling a trailer in my tow tune. I very satisfied with my choice to go with Goerend and I'd recommend this product to anyone.
