So my truck just rolled 93,000 but I plan on taking it in this week to have the 100,000 mile service done (I've got some time off this week). In everyone's opinion, what are the best things to have done? I've listed the things I want to have done below....

1. Transmission Pan Drop, Fluid and Filter Change (Better than Flushing?)
2. Transfer Case Fluid Change
3. Power Steering System Flush and Fluid Change (Just installed New Steering Rack a Few Weeks Ago)
4. Diagnosis of Timing Components (Cam Phasers, Tensioners, Chain Guides) Been noticing some knocking and ticking lately but luckily these parts are covered under my extended aftermarket warranty.
5. ANYTHING ELSE????

I just recently changed the rear differential fluid along with rear brakes and pads, new rear axle seals, new steering rack, new IWE's, new cv axle, new vacuum lines, passenger side wheel bearing, universal joints, all new plugs and coil packs, cleaned MAF and throttle body, etc. All these parts have been installed/replaced within the last 5,000 miles.

I plan on installing a new Fuel Pump Driver Module and New Fuel Filter this week before I take it in and also still have a set of OEM Motorcraft VCT Solenoids that need to be installed. I try and do as much preventative maintenance as possible and want to make sure this truck will get me through the winter with no issues. Please let me know if I've missed anything...I only have a few payments left and then she's officially mine!

bump.

Transmission Pan Drop, Fluid and Filter Change (Better than Flushing?) No, but better then nothing at all. With only this method being performed, you'll get about 5 clean quarts of fluid added to about 6 or 7 dirty/old oil.


Take it to a good transmission shop; they will inspect and recommend (or not if the transmission has "issues") a low pressure flush.

So a flush is better than a pan drop at this point? I could be wrong but I thought that after our trucks get upwards of 100,000 miles that flushing causes problems? This is just a rumor I heard, last flush I had done was at 65,000 miles and I've never had transmission issues.

Also thinking about having a fuel induction service done...I know our trucks can have injector issues sometimes....anyone know the cost for the service? Or maybe a price paid for 100,000 mile checkup? Thanks in advance.

Every high mileage vehicle i've ever seen get fresh slick transmission fluid put in ends up needing a new transmission shortly thereafter. My dealer wanted $2,500 for a 150k mile service so i just researched the parts i wanted done and have either done them myself or will take it to the dealer when i feel it needs it. $2,500 for a service is absurd.

I only have 93,000 miles...

Agreed. Drop the pan, change the filter and replace the fluid lost from the pan drop, recommend against the flush.

And flush your brake lines.

Well it's too late...Had the transmission flush done, fuel induction service, fuel filter change, transfer case fluid changed, diagnosis of timing components (which were fine I guess). Price came to $575 with tax.

So now I guess my transmission is doomed? I've heard so many arguments against flushing, and then I've heard just as many that support it. Why would you want to mix seven quarts of new transmission fluid with 7 quarts of dirty transmission fluid (refill after pan drop)? I know after a while (forgive my terminology, I know very little about transmissions) certain materials build up in the transmission and it gets used to shifting that way, but the last flush I had was about 30,000 miles ago and I've never had any transmission issues. Any thoughts? Truck currently has around 93,000 miles on it. Last flush was done at 65,000 I believe.

If you flush it frequently, you should be good. If you've never done it and suddenly you do, prepare for a rebuild. Keep us updated. I'd like to hear how it works out for you.
