If your Corona box truck slips, hunts for gears, or is late to shift, we start with a full transmission diagnosis and fluid flush in our Yorba Linda shop, minutes up the 91. We service Allison and manual gearboxes in-house, and coordinate any complete rebuild through our vetted transmission partner network for one accountable timeline.

Note: We flush, diagnose, and remove transmissions in our Yorba Linda shop and coordinate full rebuilds through our vetted transmission partner network, giving Corona fleets one accountable point of contact.

## What this includes
- Transmission fluid and filter flush with the correct Allison or manual spec fluid
- Road test and live temperature, pressure, and shift-solenoid data capture
- Pan drop and debris inspection to grade internal wear before any teardown
- Governor, valve-body, and solenoid diagnosis for harsh or late shifts
- Cooler line and thermal-bypass inspection to stop repeat overheating
- Coordinated full rebuild or reman swap through our vetted transmission partner network
- Fleet scheduling that keeps Inland Empire trucks moving between service intervals

## Who it is for
- Corona delivery fleets feeling slipping, flaring, or delayed shifts under load
- Operators overdue on Allison fluid and filter service in stop-and-go Inland Empire routes
- Fleets that want in-shop diagnosis with rebuilds coordinated through one accountable partner

## Pricing
Fluid service starts near the low end; full rebuilds are quoted after inspection and coordinated through our transmission partner network. Mechanical labor billed at $260/hr.

## FAQ
### Do you rebuild transmissions in-house?
We perform fluid service, diagnosis, and removal in our Yorba Linda shop, then coordinate full rebuilds through our vetted transmission partner network so Corona fleets deal with one shop start to finish.

### How often should a box truck transmission be flushed?
Most Allison-equipped box trucks in heavy Inland Empire duty benefit from fluid and filter service every 25,000 to 50,000 miles. We confirm the right interval for your Corona routes during service.

### Can you tell if I need a rebuild or just a flush?
Yes. We drop the pan, read live data, and grade wear before recommending anything, so Corona operators never pay for a rebuild a flush would have fixed.
