When doing a total trans fluid change using the trans oil pump to move out the fluid into a drain pan while adding new fluid to replace it can take 30% more fluid then the trans holds before the fluid coming out is clear.

If doing drain and refills it is going to take more fluid and one will never get it completely clear as it will always be mixed with old.

 

I know is been 2 months shame on me, when a gravity fluid oil pump push from the trans is done does this mean whats in the TQ Converter will be fully pushed out (your/the 30% more usage) ?

 

If the trans holds say a total of 6 quarts it may take 30% more then this to completely flush out the old fluid.

If one does trans pan drain and refills, the fluid will never be as clean as using the trans pump method to force the fluid out.
