You should always refer to your owners manual for the OEM recommended service intervals. To preserve shift quality and promote longevity, 25,000 to 30,000 mile intervals are an industry standard more frequent service may be advised if you tow frequently. Every drop of ATF may not be replaced, but done periodically the transmission will, for all intents and purposes, receive the same inherent benefits. As an added bonus, it's a relatively simple procedure for the DIY mechanic who has access to basic hand tools.

In the end, it's hard to argue with the traditional service procedure, which is less controversial and has been a time proven method of prolonging transmission life and maintaining shift quality. Additionally, some service shops may sell you a 'flush' but will neglect to drop the transmission pan and replace the filter. Keeping in mind that there are obviously strong opinions on both sides, some argue that a power flush 1) may dislodge particles and deposits that otherwise pose no threat, 2) often use detergents and/or cleaning agents that may precipitate complications, and 3) force fluid to flow in unnatural directions, placing unwanted strain on seals. However, the power flush is widely controversial. A basic transmission service does not remove ATF from the cooler lines and passages inside the transmission that hold fluid. The benefits of a power flush are obvious, as most traces of the used ATF are theoretically removed. Have them remove the transmission fluid pan, replace the transmission filter, and then flush new ATF into the transmission while simultaneously removing the remaining old fluid.īasic transmission service - Drain the transmission fluid from the pan, drain the torque converter (if applicable), replace the transmission filter (requires removal of the transmission pan), then top the transmission off with new ATF. Power flush - Take the vehicle to a reputable service shop that has access to a power flush machine. There are basically two options with regard to transmission service.

There are those who believe a complete fluid flush is ideal, those who believe a transmission flush is ill advised, and then there are certain transmissions that the manufacturer claims are 'filled for life' and do not require service. Transmission service intervals and procedures are a highly controversial topic.
