Thanks again for your service. It's truly a pleasure dealing with your company! I remember talking to Dave on the phone late on a Saturday night when I was dialing the line pressure in on my 47RE from your guys thinking, "This is an amazing company here. I am talking to the owner and he is dropping what he is doing to help get mine dialed in!!! Appreciate all the help and amazing customer service.

Excellent and knowledgeable service provided & extremely well equipped. Very modern repair facility with extensive equipment and capability. Super service often commands top dollar, but I was surprised and delighted by the reasonable rates. You folks are a real credit to Iowa hospitality and capability & are a tremendous credit to the profession.

I Just Wanted To Say THANK YOU.... I honestly can say that in 33 years and 15 years of working with companies in the automotive industry, that i never, and mean never have found a company and name as well as Goerend... The customer service you all provide is by far the best I have ever seen both in warranty and in just technical help. I wish there were more companies like GOEREND. THANK YOU Very much. 10 stars on a five star scale.....

I've just finished putting a thousand miles on my twin turbo 05 Cummins truck with a 15 blade leftcut triple disc converter, valve body, billet input, flex plate, and oil pan. All I can say is WOW. This truck has been completely transformed. I've driven with a 10,000 pound trailer and empty unloaded ect. in mild to wild tuning and this thing just plain works. I've seen 20-30° cooler transmission temperatures, 2-3 MPG increase in all different types of driving other than straight HWY OD Lock up for obvious reasons. The converter spools the twins perfectly and transfers so much more power to the wheels when unlocked it's actually almost unbelievable. I am so happy with the truck now I cant recommend this stuff enough! Thank you very much!

Goerend converters are 2nd to none and I haven't seen a warranty or a company that is close to competing. Really there is Goerend and then there's everyone else.........

This is my 94 2500 4x4 12 valve Dodge/Cummins with 284k miles on it. I have a Goerend Triple Disc Torque Converter, Full Goerend Valve Body, Goerend Billet Input, and billet strut and anchor kit from Goerend. I have owned this truck for 10 years and have had the Goerend parts installed for around eight years. I do everything with this truck. It is mainly my daily driver, but I also haul with it and occasionally I pull and drag race with it. The transmission has been flawless since I installed the Goerend parts, and they have helped to make my truck much more reliable as well as much more fun to drive. Goerend is the best in the business. The truck is grossing about 26,000 pounds in the picture and the transmission handled it great and really gets the power on the ground thanks to the addition of the Goerend parts.

Dear Goerend, If everything you do is as nice as your 48RE pan... You have a customer for life. To include the filter, gasket, spacer block, pan hardware, AND a socket for the pan bolts.... crazy and Very appreciated. Awesome Product.

I rebuilt my 48RE almost a year ago with Goerend parts and it has preformed flawlessly! I can't say enough about the customer service, being that almost a year before I rebuilt the transmission, I called them with a question about second gear that was slipping very bad. They were very helpful and told me to adjust the second gear band and it would buy me a little more time before I had to rebuild it. Needless to say, that right there showed me what kind of people these guys are and that they weren't out to get my money any which way they could, when every other transmission shop within a 100 mile radius of me was telling me to haul it in for a rebuild!! I'll tell anyone about Goerend Transmission and the honest services they provide, which is something that is hard to find in a business these days..
