RoadRunner Transmissions

DieselFetish.com is proud to partner with RoadRunner Transmission to offer full manual transmission overhauls — with a warranty and fair pricing.

The listed price covers a full overhaul of your transmission. Send in your unit, and we’ll bring it back to like-new condition and ship it back to you. RoadRunner Transmission is a dedicated manual transmission specialist, handling hundreds of NV4500s, NV5600s, G56s, ZF5s, and ZF6s every year.

Each full overhaul includes:

  • New bearings, synchronizers, and seals

  • Necessary updates and repairs to ensure the unit meets "like-new" standards — assuming you provide a good core

Don’t have a good core? No problem.
Almost every transmission is rebuildable, the question is: is it worth it? Every transmission we receive is fully torn down and inspected. Once we assess the condition, we’ll provide an estimate for the cost to bring your transmission back from the dead.
