Does Blackened Transmission Fluid Need Replacement?

[GabriellaDella]

Blackened transmission fluid requires replacement. Here are common methods for replacing transmission fluid: 1. Gravity Drain: This is the most common and easiest method, but it cannot completely drain the transmission fluid. Residual fluid often remains in low spots and dead corners. 2. Machine Flush: New transmission fluid is added to a flushing machine, which connects to the transmission's fluid lines. The machine functions by pushing new fluid to flush out the old, ensuring a cleaner replacement. This method more thoroughly cleans the fluid passages. Signs of deteriorated transmission fluid include: 1. Jerking Issues: Vehicle shaking or gearshift jerking may indicate clogged valve bodies due to contaminated fluid. 2. Abnormal Noises: Caused by gear deformation or excessive sediment buildup in the oil pan.
