My old 2002 tacoma just hit 50,000.I have drained and filled it several times over the years.I dropped the pan and changed the filter at 25,000.I'm going to take it to dealer and have the fluid exchanged.My question is should I change filter before or after flush.The fluid on the stick looks good just a little darker than new fluid.Just curious.Thanks

 

I think I'll just drop the cooling line and do it myself.Can't stand anyone working on my truck even a dealership.

 

Good choice but if you've already drained and filled several times and you're only at 50K I would think the fluid is fine. Unless you tow heavy loads..?
