I was all set to "DIY" my 4060 last year but after checking Transynd prices at about 30.00-40.00 a gallon x 7+ gallons and the filter kit(60-70 bucks), the price at my local CAT/Allison authorized dealer was VERY reasonable so you might want to check your dealers out in case your not up to crawling underneath and getting rid of 7 gallons of fluid.
