Product Description

Goerend Triple Disc Torque Converter 5.9L Cummins (1994-2007)

All Goerend converters were developed using a chassis dyno, transmission dyno, and extensive testing on live trucks. 

FEATURES:   •Triple Disc Converter   •Billet front cover   •Ideal for modified trucks that tow, commute, or race    •If purchased with a Limited Lifetime Warranty: Price includes 1 FREE Stall Change (within the first year to the original owner)    

STALL SPEED: Different stall speeds are available for this converter, depending on your truck's horsepower level and turbo size(s). The chart below can help you to determine what stall speed is right for you! 

EXTREME CLUTCH UPGRADE: The upgrade to a "Goerend Extreme Clutch" is recommended for any trucks with 1,000+ HP. Converters built with an extreme clutch upgrade include a reaction plate that is 2.5 times thicker than the normal plate in order to absorb more heat. 



At this time we are experiencing a large volume of converter orders - Please allow 3-7 business days before shipment. Fixed freight cost ONLY applies to UPS Ground Shipping. If you select anything other than ground freight on a converter order we will need to contact you to discuss availability & adjust freight amount. If you need a rush order, please call us to order! (563) 778-2719   

Choose Your Stall Speed: 
The most versatile converter offered. It is loose enough to spool most turbos, in most elevations and climates, while maximizing low end grunt and keeping the torque converter tight enough when the turbo lights and horsepower is being made. This converter should go in trucks that TOW and WORK HARD.  Approximately 200-400 RPM lower than a stock converter. 
This converter works well with: •Stock turbos from 0 to 11,000 foot elevation   •2nd generation dodges (0 to 4,000 foot elevation) with stock to 58mm turbos   •3rd generation dodges (0 to 4,000 foot elevation) with stock to 62mm turbos 

Used for light to heavy towing. This converter stall is equivalent to a STOCK converter stall. 
This converter works well with: •2nd generation dodges with 60-62mm turbos @ 0 to 4,000 foot elevation   •3rd generation dodges with 63-71mm turbos   •0 to 4,000 foot elevation with 67-71mm turbos   •0 to 11,000 foot elevation on 63-66mm turbos

This converter will be approximately 300 RPM looser than stock. It is a higher stall to help get large turbos spooled. THIS STALL IS NOT RECOMMENDED FOR TOWING. 

We have many other options for stall speeds if none of these fit your application. Please call us to discuss (563) 778-2719


What sets our converters apart from the competition?

We design, manufacture, and build our converters as well as many of the internal converter components in-house from start to finish. This ensures that our dimensions are correct and will work with your transmission! Since our converters are all produced in-house, when you call us you are talking directly to the manufacturer – which is very rare in this business – and allows us to answer all of your questions quickly and accurately. Our 7 in-house CNC machines are used to manufacture our billet converter covers, billet clutch dampers, stators, stator caps, races, and many more of the components in our converter builds. Our knowledge, equipment, and PATENTED converter components allow us to build your converter to match your needs – no matter if you use it as a daily driver – or a dedicated race truck! At Goerend we care about our customers - our multiple patents have PERFORMANCE in mind – they have been created to cure specific performance problems – not patented simply to ease the manufacturing process!

We have been in the automotive field since 1947 – with a focus on diesel trucks and converters for the past 40 years. At Goerend’s we value QUALITY not quantity, which is why we have invested in several on-site specialty tools and quality equipment to allow us to manufacture and test our products beyond what our competition can do – making us a top producer of quality converters for diesel trucks. One of our specialty equipment pieces is our one-of-a-kind SuperFlow dyno which is comparable to the type of equipment found in research labs at the OE (Original Equipment) Level – i.e. GM, Ford, Chrysler, Toyota, ETC. It is used to test our converters for: Torque Converter Pump K-Factor, Turbine K-Factor, Speed Ratio, and MUCH more! See more of our equipment pictures on our “Goerend Equipment Page”.


Torque Converter Core Charge: The core that is returned to Goerend Transmission must be a usable core of the same model (i.e. if you are purchasing a converter for a 2006 truck - the core you return MUST be from a 2006 truck), NO part of the core may be rusty, NO part of the core may be damaged in any way. IF any of these statements are true about your core, you may receive only a partial credit towards your core OR you may not receive any of your core deposit back. When we receive a usable core of the same model that has not been modified, the core charge will be refunded with a credit to your credit card. If you have any questions about what cores are accepted - please call us! The $350 core charge IS A DEPOSIT - not the price to keep your core. Click HERE to learn more about which types of cores are acceptable to send back to us.

  1. Perfect Converter 5 Star Review

    Posted by on Mar 28th 2019

    Knew it was good right out of the box. Very well made clean machined converter. We opted for the 17ss based on the web site recommended stall. It is a mild upgraded 2007 5.9 truck used to tow and play. The converter matched the turbo like the same guy built both pieces. On the road the Lock-up feel like it hits another gear. Couldn't b e happier and look forward to purchasing for our next upgraded trans rebuild.

    My son and I have both purchased these converters and run them every day from pulling cattle pots to hay and daily driving these things perform great.

  5. Best Money Spent Hands Down!!! 5 Star Review

    Posted by on May 31st 2017

    Personally used a 900/400 on my 2nd gen for years. Hands Down best purchase I ever did as a upgrade to my truck. Sense then Ive used everything from 900/400 to a 17-250 and all seem to amaze me on how well they perform. Not once have I had a failure on a Goerend converter by itself. Ive used them from in every horsepower rated truck from stock to nearly 1500hp. All perform flawless

  6. best upgrade ever 5 Star Review

    Posted by on May 10th 2017

  7. Best in the business 5 Star Review

    Posted by on Mar 24th 2017

    Holds powers flawlessly! I have around 30k on a in house goerend Trans with triple disc TC and has always been up to the challenge. Nothing comes close to Goerend built parts! Little over 400rwhp, turning 35" tires and has never missed a beat!

  8. Bullet proof 5 Star Review

    Posted by on Mar 17th 2017

    This TQ has been in my truck for three years at 800hp and towing 35000LBS it has never slipped!

  10. Simply the best convertor Ive ever used in a rebuild 5 Star Review

    Posted by on Mar 17th 2017

    As a dealer for Goerend products I have used hundreds of these top quality convertors in many many builds and have nothing but great reviews from every single customer that has received one of the triple or single billet convertors Daves staff have sold me. Ive tried several others in my personal stuff and I just cant say Ive been nearly as happy as I have ever been with the Goerend products. Top of the line parts, people, and equipment in small town Iowa.
