Transmission Overhaul

There are hundreds of parts inside the transmission and they all have to be removed in order to rebuild it properly.

An Overhaul usually takes 3 to 4 days to complete.

 

When we overhaul or rebuild a transmission, we hoist the vehicle up in the air and one of our mechanics remove the transmission from the vehicle.

The transmission is then completely disassembled, cleaned and all components are inspected for wear.  We replace all bad hard parts, clutches, sealing rings, gaskets, seals, thrust washers, bands and any solenoids that are have failed.

We also clean and go completely through the valve body.

While the transmission is out of the vehicle, we flush the cooler line system, cleaning all contaminated particles from the lines.  We also replace any bad cooler lines if needed, as a bad cooler line could cause fluid leakage causing the transmission to fail and/or burn up.

Before the transmission is reinstalled and for the customer's convenience, we also replace the engines rear main seal, to save them hundreds of dollars should it need replacing later.

We also replace any bad or broken transmission and motor mounts, as well as axle seals and axles.

The transmission is then reinstalled and filled with fluid, test driven and adjusted before returning to you.
