To Change or Not To Change Transmission Fluid...?
I have an '88 S10 Blazer with a 700R4 transmission. It has almost 200,000 original miles on it, and I'm not exactly sure how many times the trans fluid and filter have been changed. My fluids are still slightly red with some mid brown coloring. I've heard from the average jobber to either change it or leave it alone, about a 50/50 split, but I thought it wouldn't hurt to hear from a ASE certified tech if possible. I have had no previous problems with my trans, and I personally haven't changed the fluids in a bout 70,000 miles. My truck is a daily driver, and by no means a play toy at all. Any professional advice is greatly appreciated.
