So I purchased this 2006 Chevy 1500 with the 4.8 V8, man do I wish I had a 5 speed transmission but anywho - I was wondering if there was any suggestions as far as preventative maintenance I should do to prevent common issues that occur with these. So far I've been on time with my oil changes, maybe over by a 1-200 miles here and there. Truck currently has 87xxx on it, the stealership recommended doing the transfercases and transmission fluids. That will be next on the list, since I just did front brakes! Any suggestions, greatly appreciated! Thanks.
