How Long Does It Take to Change Transmission Fluid with a Flushing Machine?
2 Answers
Changing transmission fluid with a flushing machine generally takes about two hours. Below is an introduction to the methods of changing transmission fluid: 1. Gravity Drain: The gravity drain method is simple and convenient to operate, and the cost is relatively cheaper. When using the gravity drain method, you only need to unscrew the drain plug at the bottom of the transmission oil pan. However, gravity draining cannot completely remove all the old transmission fluid, as it can only drain about 60% to 70% of the fluid. 2. Flushing Machine Method: Using a flushing machine involves higher costs and requires the availability of a flushing machine. The flushing machine method can remove up to 90% of the old transmission fluid, making this method more thorough. However, using a flushing machine requires more new transmission fluid, which also increases the overall cost.
I've been in this business for years, and the time it takes to change transmission fluid with a machine isn't set in stone—usually wrapped up in 30 minutes to an hour. For regular sedans, 30 to 45 minutes is typical, but with larger vehicles like SUVs that have greater fluid capacity and complex lines, it might take around 50 minutes. Don't think it's just about swapping fluid; the technician also needs to check fluid levels and the condition of the old oil. If metal shavings or anything unusual are spotted, extra time will be needed to troubleshoot. By the way, booking ahead saves a lot of hassle—I've seen guys without appointments end up waiting all morning. Opt for a professional shop with reliable equipment, since this method ensures complete old fluid replacement, protecting your transmission's lifespan and maintaining driving comfort. The whole process is fairly quick, but don't rush—safety first.
