[QUOTE="Richard L, post: 541836, member: 52972"] Todd, I know you said you last, so that's why my response was addressed to Cayment, dreman, and Gavin. The main points made in your college text book are for the most part correct however there are some things that are overlooked or not mentioned. The statement: <b>"Many transmission experts say that most transmission problems can be prevented by changing the ATF and filter regularly for preventive maintenance."</b> Of course transmission experts will always recommend changing the filter even when they are nothing more than the plastic or metal screens they describe. That's their bread and butter! Like I said, if you are going to drop the pan to change the fluid (which up until recently was the only way to change the fluid), by all means spend the extra money to replace the filter! The transmissions that have the plastic and metal mesh strainers have no more problems than ones that may have a finer filtering system, and they probably have less problems than the Sport Trac's 5R55E. The other point I made several times, is that if you change the fluid regularly (especially with a flushing machine) your filter will last at least 100K miles. As your book also stated, the ATF is the most neglected fluid. I know people who have never checked or changed their transmission fluid and drove their vehicles well over 100K miles and never had a problem with the transmission. Your book also states as I have as well, that heat is the biggest enemy of the transmission and the fluid. Your book also states that the filter traps most of the normal wear particles. which clearly means it does not trap all of them, so some are getting through. Finally, if the filter is trapping and retaining all these particles, why bother putting a magnet in the pan. Those particles will never get reciruclated if they are trapped and held by the filter so there would be no need to have a magnet in the pan. The answer is simple. The filter does not filter efficiently and significantly large particles are allowed to pass through the filter media. While this may be better than the plastic or metal mesh style filters, the difference is like comparing 1" gravel to pea-gravel. You can pack both as tight as you want, water will still drain thru it. ...Rich [/QUOTE]
