Hey everyone, I have a 2004 CCLB 4x4 with about 45,000 miles. I just picked it up a few weeks ago and don't know much about the history but the last week or so I have had intermittent issues with shifting into drive and reverse. When shifting from Park to Drive/Reverse it doesn't seem to be engaging. There isn't any slop or resistance in the shift lever, the indicator moves appropriately, but when I step on the gas it just revs up as if I were still in neutral. I usually just put it back in park and try putting it in gear again and it will work fine the next time. Going down the road there are absolutely no issues, slipping, etc... it's just shifting between Park, Drive and Reverse. Is this as simple as worn out shift linkage under the dash or is this indicative of larger issues? What kind of diagnostics should I be running to figure out where the problem lies?
