Try clearing out all fault codes then operate the vehicle and see which codes come back again.Some of these codes may be old history codes that were never cleared out when the transmission was replaced or from sitting.If you can do this then post back here which codes are coming up again this will help.If this was already done and these are the codes that are coming up again let me know.

Was it parked in an area where rodents may have been present at all to possibly chew up any wiring?
Inspect under the hood in the engine bay at the engine wiring harness on top of the engine and sides as well as leading to any under hood fuse panel and see if you see any nests or chewed up or damaged wiring.I have seen when a vehicle sits for a period of time where a rodent can chew up this wiring.I see this quite a bit.
If the engine isnt running rough at all but you have a ticking noise most common I have seen cause this here is valve lifters at fault needing replaced.I have seen these cause this tick before as they become weak over time needing replaced.This would need to be checked into further in some cases with th engine taken apart to fully inspect to be sure it is the lifters needing replaced here.
Let me know if you need anything else and feel free to rate my help here.
Does this have the V6 or V8 engine?
I apologize I see it is the V6
Let me check real quick
The cost is around $300 for the lifters and 6 hours labor to have them replaced.These are actual lash adjuster lifters and the cam shafts need removed to replace them.This will involve some special tools to lock in the timing components to replace these here and is usually best done by a shop or dealer that has these tools to lock in the timing components to then remove the cam shafts to replace them.
No,if it doesnt get any worse and if it runs o.k. you should be o.k. for now until you can have it repaired but I would have it checked into as soon as you can and repaired.If it gets noisier or starts to run poor then I would shut it off and have it checked into.
