That said, if you want to change the fluid on the off chance that it gives you a little more time, go ahead. If your problem is a clogged filter, it would help, but it wouldn't address the issue of why your filter is clogged. If you do it, use factory spec fluid, and a new OE filter. You have to consider that your transmission is not healthy, though, so changing the fluid may make it worse or better. It shouldn't be considered a cure, rather a bandaid.
I can agree that sometimes chaning the fluid can be a way to speed up the means to an end. I remember when I was on Toyota Tacoma forums, and just like here, people had mixed reviews of changing fluid when their transmissions started giving them issues. Either way, if he calls/emails me, I'd be interested to take a look at it since my X doesn't exhibit any symptoms like this.

At this point it won't happen till after the new year, but I'm looking forward to doing a complete rebuild on a 5HP24 so I can see first hand what failed clutches, 1st/Reverse drums, etc look like when they break/fail.
