I have a Cummins with a G56 trans. I’ve used this gear oil twice now and have had no problems. I’m currently sitting at 150k miles. I’m in some of the Cummins FB groups and I always recommend this product.

I’m very pleased with ECD and having the part in stock and ready to ship. Also, I received my part in a timely manner. I’ll purchase more parts from ECD in the future.

Very pleased with performance of clutch and how fast it was delivered

Very quick to ship
