Here is the problem.....before I start let it be known that I fought myself for a while before starting this debate. If you disagree that is fine...Differnt strokes for differnt folks
Waiting to change the fluid extended periods of time causes a build up of particles in between the friction plates. By driving the car like this it puts small grooves in the friction plates....This is not really that bad of a thing. The particles will stay there and cause the plates to continue gripping. No big deal. However, by changing the fluid once these particlaes are in place it can wash them away from the detergants in the new fluid. Especially if you flush the tranny with a pump
I dont believe in changing tranny fluid. Most people do and thats fine. Lets put it in to perspective. Right now I have 163,000 miles on my 2000 dodge ram 2500 diesel. NEVER have I changed the tranny fluid. Never. I pulled bulldozers horse trailers across country. The truck has been through hell and back. Not to mention it came with 235 HP and 500 TQ and is now putting 328 750 to the wheels. Back to putting it in to perspective a transmission flush is ussually over 100 dollars, so lets sat you change it every 10K miles as recomended in this thread that would be 1600 dollars when a replacment tranny would cost me 1800. Doesnt make sense to me. Even if my tranny failed today 160K plus is not a bad run for a auto tranny.
Those of you that do your own maintenace. By droping the pan and changing the fluid and filter you have accomplished almost nothing. The TC hold more fluid than the pan does in most cases and with the pump not running "car off" there is no way to get the rest of it out. Now you are mixing old fluid with new.
Take this for what its worth and I am not trying to sell my views to anyone on here. If you change your fluid then good on you.
