Transmission Fluid Change?
We all know the tranny fluid is 'spose to last for the truck's lifetime. But for any nonbeliever's (like me), I ask the question: has anyone changed out their fluid? If so, where did you do it (or have it done), what extras were needed (new gasket?), and what fluid, how much $ ???
Thanks

I flushed and changed the tranny on a 1995 chevy s10 blazer once at 120K miles, the tranny promptly went out and cost me 2000$ to replace. Tranny guy said that changing the fluid removes the friction material from the oil and makes it to slippery and the old worn clutches then dont work right. Now whether he was talking about just that particular tranny or in general I dont recall as it was 6 years ago, but Ive had a ton of high mileage vehicles in my day, mostly fords, and this is the first one ive ever had a problem with.
