B1 Service For Your Car

The B1 service indicator popped up on our 2015 Honda Fit at around 14,000 miles, signifying it was time for the Fit’s second oil change following the A1 oil change at 6,800 miles. The Fit’s maintenance minder system sends an alert when certain services are due based on miles traveled and engine-operating conditions.

The “B” represents an oil and filter change plus mechanical inspection, while the “1” means it’s time for a tire rotation. The B1 service should include the following inspection, according to the Fit’s owner’s manual:

  • Inspect front and rear brakes/service as necessary
  • Check parking brake adjustment
  • Inspect tie-rod ends, steering gearbox and boots
  • Inspect suspension components
  • Inspect driveshaft boots
  • Inspect brake hoses and lines (including the antilock braking and vehicle stability assist systems)
  • Inspect all fluid levels and condition of fluids
  • Inspect exhaust system
  • Inspect fuel lines and connections

Our local dealership had its own interpretation of the B1 scheduled maintenance that included a brake service at an elevated cost even before the inspection of the brakes. We declined this front rotor cleaning and front caliper slide pin lubrication considering our car’s low miles and owner’s manual only suggesting service if needed.

Change the Transmission Fluid

Yes, though how often this service should be performed varies by manufacturer and vehicle, and it’s open to debate.

The manufacturer’s maintenance schedule for many automatic transmissions doesn’t call for fresh fluid until 100,000 miles or, with some Ford transmissions, even 150,000 miles. A lot of mechanics say that is too long and it should be done at least every 50,000 miles. Manual transmissions may be on a different schedule, so it’s best to consult the maintenance schedule in the owner’s manual.

Like other vital automotive fluids, transmission fluid deteriorates over time. Hard use — such as frequent stop-and-go city driving, hauling heavy loads, trailer towing — will accelerate the deterioration. That kind of driving raises the operating temperature of the transmission, and heat puts more strain on the transmission and the fluid, which helps facilitate gear shifts, cools the transmission and lubricates moving parts.

If you do a lot of driving under high-stress conditions, you should check the transmission level more often and have a repair shop check the condition of the fluid. Transmission fluid often is red but can come in other colors, and as it deteriorates it tends to turn darker. It may also acquire a burned odor that could indicate it needs to be changed or that the transmission is developing mechanical problems. Another indication it needs changing is dirt or other debris in the fluid. When you take your vehicle in for an oil change or other routine service, the repair facility may urge you to pay for a transmission-fluid change or flush. Even if they can show you that the fluid is darker than original, that might not mean you need fresh fluid right now. Step back, check the maintenance schedule in your owner’s manual and see what the manufacturer recommends before you decide. This also will give you time to price shop.

Many repair shops use flush systems that force out the old fluid and pump in new fluid. Though that sounds good, some manufacturers say you shouldn’t do that (Honda is one; there are others), so you need to know this before you agree to a flush. Look in your owner’s manual. Some manufacturers, such as Honda, also call for their own type of transmission fluid and warn that using other types could cause damage. Moreover, some automatic transmissions have filters that should be cleaned or replaced when the fluid is changed. Make sure the repair facility is using the correct fluid and procedures for your vehicle.
