Tech Tip Tuesday: Fluid Exchange or Drain and Fill?
These services replace transmission fluid in different ways.
A drain and fill removes part of the old fluid through a drain plug or by removing the pan. If the pan comes off and the filter is serviceable, the filter can be replaced and the pan inspected.
A fluid exchange uses equipment connected to the transmission’s cooler circuit to replace a larger share of the fluid. It does not repair existing wear, and it may not include removing the pan or replacing the filter.
Neither service is automatically right for every vehicle. The correct choice depends on the manufacturer’s procedure, mileage, service history, fluid condition, and any symptoms the vehicle has.
We inspect the vehicle first, then recommend the service that fits it.
