2002 GMC 2500HD Duramax Fluid change

**The Reds** · 11-28-2012, 02:16 PM

Thanks for all of the great advice on capacities and bolt sizes. Truck is new to me and has 240k on it now. Changed to Mobil 1 5w40 and a Fram XG9100 filter. Changed front and rear diff fluid, Mobil 1 75w90 LS. Purchased a pump from Walmart to transfer fluids. Harbor Freight 3/8 inch breaker bar fit perfect in rear diff bolt. Changed Transfer case and added Transynd. Followed expert advice from, HZJCM8, and performed a double Transynd Flush with a new Allison filter on both fills. Was stationed at RAF Chicksands btw. Purchased new oil and trans bolts from GMC dealer, 16 dollars, had rubber seals. No leaks at all. All advice was perfect, capacities and bolt sizes. Helps to make sure one has all to do the job. Hate to be stuck and have to get something and have to crawl out from beneath the truck. Truck is easy to work on and has room without jacks. Thanks MadJack, Transynd fluid and filter package was cheaper from West to East Coast than dealer 2 miles away. Ready for the east coast snow this winter.

Dave , best mechanic I know, works on my car that will sit during the winter months. To low to get under.
