Hi there. Gary you reading this? I value your opinion and others as well of course.
I have 69000km on my 2000 GMC Sierra SLE 4X4. It is a daily driver. I never haul anything in the bed...only a 500lb snowmobile a couple of times in the past. The tranny fluid has never been changed. Everything works as always since new. No problems that I am aware of. Yesterday I called a local tranny shop(excellent reputation) for a price on a transmission fluid change. I also inquired about a auxiliary cooler. The price that they gave me was $335 taxes in (Canadian) for the tranny flush, cooler and installation...... So my questions are....
Do I really need a cooler ?? Is a tranny flush bad? Or do I just get a fluid/filter replacement? Is the price quoted good?
Thanks for your help, Glenn
