# 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
