How we handle it

Clutch replacement is a real job on a Class 8. Transmission has to come out, which means driveshaft, crossmember support, slave cylinder, and on AMTs the air-shift and electrical disconnects. We set up the work to do it efficiently at your yard. AMT diagnosis is scan-tool work — Eaton ServiceRanger for UltraShift, OEM tools for the brand-specific units. We don't replace AMT components on guesses; the diagnostics are usually clear when we have the data.

Parts & warranty

Clutches OEM (Eaton Fuller, Spicer/Dana on what they came on). Transmission fluid to the spec the OEM calls for (Eaton PS-386, Roadranger fluid, etc.). AMT-specific parts OEM only. 1-year parts-and-labor warranty.

Frequently asked

How long does a clutch replacement take on a Class 8?

Typically a one-day job at your yard — 8–10 hours including transmission removal, clutch swap, and reinstall. AMT-equipped trucks add a couple of hours for the electrical and air-shift reconnect.

My AMT is bumping into gears hard. What is it?

Several possibilities: clutch wear, air pressure issues to the shift system, sensor drift, or fluid contamination. Scan tool shows us the live data and the fault history. We don't guess our way into a $2,000 part replacement.

Can you do a transmission rebuild?

Pull and replace yes; precision rebuild we send to a transmission specialist. Internal rebuild needs the alignment fixtures and clean room a specialist has. We coordinate the swap.

How do I know my clutch is wearing out?

Loss of free-play at the pedal that you keep adjusting back, slipping under heavy load (especially on grades), chatter on engagement, and burnt smell after hard pulls. If any of those show up, clutch service is in the near future.

“Brennan was great — absolutely hire this guy. I own a local tree company in Goodlettsville and one of my work trucks broke down at short notice. He was able to get there within a day or two and diagnose it. My turbo went out on one of my vehicles — when I went to the dealership they told me the wait time was forever and the process would include taking the cab off, which wouldn't work well with my current setup. Within one day he was able to replace my turbo and get it running so I could get back in business. The job was really labor-intensive but he made quick work of it and it runs even better than it did before. He's now the main guy I go to.”

“We've used Blacktop Mobile Repair twice this month, and both experiences have been nothing short of amazing. They run a top-notch operation, and it really shows in the quality of service and professionalism they provide. Jacob, the service tech, went above and beyond to make sure our truck was taken care of. He even drove out of his way to make sure he had the exact part needed to fix the truck and get us back on the road quickly. That level of dedication and commitment is hard to find. As a trucking company, downtime is costly, and having a team like Brennan and Jacob we can rely on makes all the difference.”

“I've used these guys in the past for an air compressor installation. Jacob was great. And recently my alternator quit on the weekend. I called Jacob on a Saturday and he helped me find one that I could pick up myself. Both times Jacob was knowledgeable & fair. A few months later — again on a Saturday — I wasn't even in their area and I called again to get troubleshooting advice. They are very good at diagnosing. Was able to pinpoint the trouble. Thanks again guys!”
