Thanks for clarifying. You can change your transmission fluid any way you like :B

No problem and unlike some others just doing a pan drop and fill is sort of like doing an engine oil change and putting 2/3s of the old oil mixed with 1/3 new oil back into the engine.:S Not what I consider a good maintenance practice.:R

But as you said one can do the maintenance whatever way they want.:W

WOW. Some people just assume. Just ask someone that does the transmission work at a dealership which one is best. He will explain why and you will never flush it again or maybe you will.

Then you need to find another dealership and not listen to the every day JOE doing routine transmission work. Remember I said flush using the pump in the tranny which is simply a complete "FLUID EXCHANGE" and not an external machine like the ever popular B&M one. Doing a power flush, back flush, or using chemicals is IMO a NO NO. There are fluid exchange machines that do it correctly. What I advocate is a procedure developed by Mark Kovalsky specifically for the 4R100 over on THEDIESELSTOP who was a FORD Tranny Engineer for many years and is what I consider a TRUE EXPERT in trannies in general and FORD trannies specifically. This procedure should be adaptable for other transmissions since it's fairly straight forward and very simple.
