A co-worker of mine just bought his kid a 99 db7, and is doing some maintenance on it before his kid takes it back to school. He wants to do a pressurized tranny flush, and asked me if i thought that was a good idea. Well i dont know cripcrap about auto trannys, so i said i would ask you guys.
pressure or no pressure? does it matter? He's getting mixed reviews from mechanics, some say yes, some say no.

Any advice is appreciated. Thanks in advance

 

bump for help

 

Your co-worker bought his kid an Aston Martin?

I would just change the fluid and not worry about the pressurized flush.

 

Pressurized is just fine and better in my opinion. It helps to go through the entire system and flush out all the **** in the lines and cooler sections.

 

most of the time non-presurized flushes won't get everything out of the lines and torque converter.
