Frequently asked questions
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.
