Default To Flush or To Drain

Okay, this is only my 2nd automatic, so I'm not the most familiar with these tranny's. I have searched the site for post on this subjuect, but it's hit/miss on who suggests what. So I decided to conduct a poll to see what people think.

My F150 will be hitting 30K miles real soon. My dealer advised me to have a tranny flush. Which of course depending on who you ask, you should or shouldn't get a flush. Those that are against the flush usually recommend a drain (drop pan, filter & gasket).

I've heard of people having tranny issues after a flush. Not sure if that was due to particular reasons or not (little metal bits). So just looking for advise. It would make me so much happier and life so much easier for me if Ford would simply put a manual back in the F150.

Make sure their system does not "back flush" under high pressure, as this can bugger up some sensitive parts.

Full flush. Any "reputable" transmission shop can perform this. I had mine done at my local Ford dealer; they run specials every so often, and a full flush cost me $89.00.

I would say at 30k,full flush,filter,everything. I have heard horror stories about flushing. But typically its from doing it on a truck with high mileage,that hasnt had it done regularly.

Flush it. Have it done at the stealership. This way you know you're getting Mercon 5 synthetic. Its the best fluid you can put in there.

Well, it would most likely be done at the dealership. So hopefully they don't have a system that would back flush.

Well, my local dealer offers the Drain for roughly $89, but for the Flush they quoted me $169-$179 if I remember correctly.

Ouch! My dealer stated the price for full synthetic would push the flush over $200, while using their basic tranny fluid (whatever that is), is the above quoted $169-$179 price. Maybe I'll look for some dealer coupons or call other dealers for their price.





Basically they quoted I needed all the following done.
  • Tranny Flush ($169-$179)
  • Power Steering Flush ($75)
  • T-Case Flush including BG44 & warranty ($79)
  • Battery Service ($30)
  • Brake Pads replaced & Rotors turned ($199 per axle).
Of course I can have the battery serviced elsewhere for roughly $10, and can change the pads myself. I do not want these horribly dusting pads on the truck again. Just have to find a reputable shop that will turn the rotors. Plan on installing the below Hawk pads, but does anyone have a good place to purchase them at?

And right now it's 8 for Flush and 2 for Drain.

Like others have stated, I've heard horror stories of people getting a tranny flush and needing tranny work soon after. Even though I have an ESP that covers the next 3yrs, this and any tranny work always concerns me. I plan on running the truck into the ground, but would hate to start having tranny problems prior to 100-150K miles.

Ok first, FLUSH! I have a 2WD w/ over 70K and I flush every 30K. Everytime I get it flushed it feels like a new truck, never having a problem. Second, I dont believe our trucks need the rotors spun, unless you have some horrible wear (please someone correct me if I am wrong). This would cause you to purchase new spindle lock nuts for the front every 30k, and they run $75 for the pair. I swapped out my stock rotors for some cross-drilled just after 60K. Prior, I had never gotten my rotors spun. I never had uneven wear, and always changed my pads prior to them getting super thin. Hope this helps
