Hello all. Just finished up with a 'fluid change' on my 1999 Chevy S-10 blazer, with the 4L60E transmission. Went easier than I thought! I've always done a pan drop, and replace the filter every 40K - 50K miles. This was the first time for a total fluid exchange. The vehicle has about 190,000 miles on it. The new fluid I used is Castrol Dex VI. Got it cheap through AA. Took about 14 quarts. Here is a link to the method I used. Let me know what you think.
