Before I change out my transmission fluid and filter....

Hi guys. 1st post and I need real insight to my 4x4 auto 2002 Jeep Liberty. I had it for awhile and I just got a routine oil change. The shop informed me that my transmission fluid and filter should be looked into.

I figured to do the messy job myself. However, I have been advised by family friends that when you mess with transmission fluid draining/filter, your transmission will get messed up. It sounds weird to me but family friends claim this to be true. One said he worked in a mechanic shop and knew those who had a complete fush only to gripe that their transmission would later go out.

Is there truth to this or plain hogwash? I am not looking at a fully flush but doing a routine change, for now.

Also: Should I go with a gasket or sealant?

I'm no mechanic but I been able to restore and rebuild old cars so changing the filter appears very straight forward (read up on it and watched some vids). My girlfriend had her jeep for 3 years and I took it to the shop for a simple oil change. The guy said the transmission fluid was brownish and wanted to charge $90 for a filter change and put fluid back in. $200 for a complete flush. For that much I figured I do the filter and replace fluid change myself to bide me time for a full flush some time. I understand I can not get all the fluid out but I figured working on it is better then nothing. She is convinced that her transmission will flop after I tinker with it after all the horror stories she heard from friends and those she knows working in mechanic shops. That is what I was hoping people could shed some truth to.

I was going to use a name brand fluid ATF +4 as recommended. I figured if the right fluid is used and everything put back together it should be no big deal and these transmission woes are unfounded.
