You dont really seem like it made a huge difference, I am wondering if it had a placebo effect
and for the love of god never take the advice of somebody from behind the counter at an autoparts store.

. I used to work behind the parts counter part time so I could get a better parts discount for all the crap I had to do to repair my personal vehicles at the shop I worked at
. The parts stores generally offer a much better discount to their employees than to indy shops. But it is usually pretty easy to tell which ones know what they are talking about. Ask them about their personal projects. A few seconds into it you will know if they are blowing smoke or have a good working knowledge.Cashiers, on the other hand, don't know jack.

Wait a minute. There is the 1 in 900,000 chance that the person knows what they are talking about.

from what I understand after the fluid gets so old it starts to lose its chemical properties. And adding new detergents and additives can throw off a delicate balance that is created.... This is what I have been told... I in no way claim to be an expert and everything I know about my truck I am learning from these guys...and by getting my hands dirty

It may have been a time that I was clouded by Puerto Rican wildflower (as Danny likes to call it
), but Im almost positive I read that the little particles of metal and whatnot that build up over time in the tranny will act as friction enhancers.When you put new fluid in, what little friction the tranny had left is gone, and hence it will no longer engage.

My experience is that if it needs changed...change it. It lasts longer than not changing it. Every time I see a tranny that "died" after a fluid change, it turns out the tranny was already dead. They were just trying the last thing they knew to gain a little extra life out of it.
What generally happens is the fluid is filled with friction material that doesn't lubricate but acts like liquid sandpaper, allowing the clutch packs to grip.
When the 'liquid sandpaper' is replaced with the correct fluid, the tranny dies because all the friction material was already gone and now so is the 'liquid sandpaper'.
