How often should I have my diesel truck’s transmission serviced?
Transmission fluid and filter changes are usually recommended every 30,000–60,000 miles, depending on towing, load, and duty cycle. We’ll help you set the best schedule.
Can a fluid change fix shifting problems?
Sometimes. Contaminated or burned fluid can cause poor shifting. A fluid exchange can help if there’s no internal damage.
What is a transmission rebuild?
A rebuild involves disassembling the transmission, replacing worn internal parts, and reassembling it to restore function closer to original performance.
How long does a transmission repair take?
Minor repairs can be completed in a day, while rebuilds or replacements typically take several days depending on parts and repair complexity.
Does transmission work affect warranty?
Warranty coverage depends on your specific plan. We can verify warranty details before performing service.
