Need some input from the ORG

Here is the brief history of my truck:

Bought Oct 2011 with 78536 miles.
Service records indicated oil change every 5k miles(original purchase and all service done at dealer where I purchased)
(previous owner had EGR coolers, radiator, and pinion seal replaced under warranty)
No other maintenance done according to dealer reports
Oil, filter, and fuel filters replaced at 80,000 miles by me.

My truck got deleted a few weeks ago.

I am now trying to get back on track with maintenance and need to know what should be done first.

1. Coolant flush (restore and restore plus) and replace with ELC
2. Transmission filters (job 1) and fluid refill
3. Differential service

I have not noticed any issues with the above systems but I would like to prevent any future problems. Any suggestions would be great. I plan on doing a coolant filter but that will probably be after the flush.

I don't believe there is a specific order to do those things but the sooner the better. Sounds like your on track and coolant filter would be a great addition to the elc coolant

I got a quote from the dealer today for $450 for transmission service (no flush). Glad that I can do most everything myself.
