42RLE tranny, it was very easy, trust me I'm no mechanic, but I love wrenching, it was simple as dropping the transmission pan, I believe it was 13 bolts holding it in. Now you could just drop the pan, catch the fluid and measure the amount that you drain and refill with new , but I did a complete flush.there are some good write ups on how to do so, and you tube lol I can show you the process with pictures if you like, but I'm currently at work it would have to wait until the weekend. Here are a few pis of the pan dropped. Remember to get all your supplies, tranny filter, pan gasket, red RTV sealer, tranny fluid ect.
