Maintenance on my Dodge Ram
2001 Dodge 2500 4x4 with Cummins diesel. I am trying a lower maintenance routine on this truck. Wondering if I am taking big risks. Transmission is a 47re automatic and I am changing the fluids in diffs, Xfer case and trans every 60k rather the recommended intervals of (I think) around 20 or 30k. I tow a small boat occasionally. Any gurus with actual experience using a similar routine have an opinion on this, either good or bad? BTW, the engine gets an oil change every 3k.
Thanks!
