# Diesel Repair. Booking & Missed-Call Recovery

*Booking and missed-call recovery for diesel shops. One DPF regen covers Defense ($397/mo). Fleet-friendly quote forms, deposits, SMS reminders.*

## Diesel Repair (Sun Belt)

Diesel work doesn't run on banker's hours. A Cummins ISX with an injector harness fault shows up at 6 a.m. with a fleet dispatcher who needs an ETA before the route runs. The shop that auto-replies inside 60 seconds wins the work; the shop with voicemail loses it.

Tickets justify any reasonable booking infrastructure: DPF regen $400–$900, EGR cooler $1,200–$1,800, 6.7 Cummins/Powerstroke injector job $3,000+, Detroit DD15 turbo $4,500. One captured job covers Defense ($397/mo) for a year. Redline Revenue installs the system: missed-call text-back, fleet-friendly quote forms with VIN + fault code + photo capture, deposit invoices that route through fleet accounting, automated SMS updates while the rig is in your bay.

## Pain points

- Phone rings during a DPF regen and you can't pull off the truck to answer
- Fleet dispatchers call three shops in 10 minutes. First to text back gets the work
- Customers ghost on $1,400 EGR cooler estimates because nobody followed up
- No deposit means the F-450 with the cracked head sits in your bay for two weeks waiting on parts the owner won't pay for

## Why a booking system matters

Diesel work doesn't run on banker's hours. A Cummins ISX with an injector harness fault shows up at 6 a.m. with a fleet dispatcher who needs an ETA before the route runs. If your phone goes to voicemail, the dispatcher is already calling the next shop in the search results. And they have a tab open with three options. The shop that answers (or auto-replies) inside 60 seconds wins the work.
The economics on diesel make every captured call valuable. A DPF regen runs $400–$900. A forced regen plus EGR cooler service is $1,200–$1,800. A full injector job on a 6.7 Cummins or 6.7 Powerstroke clears $3,000. Miss eight calls a month at those tickets and you've leaked $10,000. Easily more if any of them were repeat fleet accounts. The math on a $397/mo booking system is: one job covers it, the rest is upside.
Fleet customers don't want to play phone tag. They want a quote-request form where they can paste a VIN, attach photos of the dash codes, and pick a Tuesday morning slot. They want a deposit invoice they can route through their AP. They want SMS reminders so the driver actually shows up. None of that is fancy. It's table stakes for the shops winning fleet work in 2026.

## Ticket examples

- DPF forced regen. $600
- EGR cooler replacement on a 6.7 Powerstroke. $1,400
- Injector harness + injector cup on Cummins ISX. $2,800
- Turbo replacement with actuator calibration. $3,200

## Caller types we capture

- fleet dispatchers
- owner-operators on the side of I-10
- construction GCs whose dump truck is down
- RV owners with a 6.7 Powerstroke pulling a fifth-wheel
