      One more question, did you or the mechanic shop have to bore the servo holes for the TCI servos?

      Due to holidays season and forwarding problems, I did not receive Level 10 rebuild kit here in Saudi Arabia and I'm still waiting for it.

      and because of that I had to use Motorcraft #MTK-K2700-F rebuild kit for the time been.

      the transmission now runs flawlessly and with the Cold-Start Valve, valve body Modification the transmission does not overheat any more even with my abuse

      The TCI servo kit did not require any boring, just a direct fitting. (I installed it in first place to to increase durability and longevity)

      Great thread and great writeup! Thanks for posting all this! :thumbsup:

      I've got a few questions:

      What are the part numbers for the (1) forward clutch piston, (2) low reverse piston, (3) OEM solenoid pack, and the (4) OEM torque converter? I wanted to located these parts as well as the prices.

      What are your thought on the OEM master rebuild kit components? Do you expect the clutch pack components and bands to hold up better than the Alto Red Eagle and Kolene components you didn't like?

      Hello -

      I'm going to be rebuilding my 5R55W soon.... did the kits you used include new bushings and bearings as well as all of the soft parts/clutches/steels? I'm hoping to find a kit that contains everything in one package.

      I really appreciate that! :)

      Did you buy all of the bearings and bushings seperately/individually or as a kit? I'm hoping I do not have to order them one at a time...

      I did not buy any bearings, just used the old ones and bushings came with the kit

      I have a stock pan do you think i could still use the remote filter from summit? I just had my transmission flushed about 1000 miles ago so anything i can do to keep that fluid clean is worth it.

      yes you can and should use the remote filter and this setup can keep your ATF fresh and clean

      Im pretty happy i found this one!

      I just got done rebuilding the suspension on my truck, and not a week later my transmission blew the solenoid pack. While investigating i found that i have a leaking seal upfront somewhere. And as such ive decided that at 140,000 rough miles its time for me to bite the bullet and rebuild this thing. Im going to practicaly mirror your build!

      A few questions for you all if your still around!

      I have the 5r55w thats set up for the v8 explorer, are there any compatabilty issues that i should be aware of for this build?

      Has anyone had any luck with the level 10 rebuild kit?
      Do those servo kits negate the need to bore and sleeve the servo bores?
      does anyone know if level 10's super solenoids come as a kit to be placed into the solenoid pack? or am i looking at buying three of them?
      Did you do the rebuild yourself? what kind of special tooling was required?
      Would that hardened input shaft fit the 5r55w as well?
      would it be wise to replace the bearings at the time of this rebuild?


      Thanks!

      5R55W have the same rebuild parts as 5R55S. the deference between them is only in the ratio and the related parts

      Finally I received level 10 rebuild kit

      The Kit consist of:

      • 5R55W/S raybestos clutches
      • 5R55W/S OEM forward bands
      • 5R55W/S OEM forward Piston
      • 5R55W/S OEM Int. & O/D servos
      • 5R55W/S OEM oil filter
      • TransTech paper and rubber with sealing rings and bushing kit
      • Superior Solutions line pressure relief valve kit A46507A-1 #K060

      I recommend buying OEM rebuild kit along with Superior Solutions line pressure relief valve kit A46507A-1 #K060



      TCI servos help preventing or actually delaying the bores wearing. if the bores wear already then you have to bore and sleeve.



      I recommend to buy the solenoid pack from ford dealer to get the latest updated version



      Nope I did it at a trans shop



      yes it will fit



      it depends on the condition of your bearing.

      But if you can replace them with Torrington Bearing then do so.

      When you run the auxiliary filter do you still run the one inside the pan?

      Although stock fliter does not contribute to oil filtering - because of the ablity of the auxiliry filter to catch smaller particals - but it is still functional as a sucction tube for ATF from the bottom of the oil pan

      I take you still change it periodically, just not as often since your changing the external one. Is it hard to get that deep pan off? I'm going to be getting my tranny rebuilt in next few months and I'm going to print out everything you did and see what it'll cost me to have it done at a local shop. I'm not hard on it but I want it to last for a very long time, obviously with proper maintenance. I have right at 325,000 miles on mine now.

      No, I don't change it at all. I just install a new one right before installing the auxiliry filter and never changed it after that. I just kept changing the auxiliry filter each time I change engine oil and I complete the ATF level with fresh mircon V eahc time.

      Nice job, it does seem a little pricey for a vehicle that doesn't have much of a re-sale value though....$4500 would buy a nice Explorer where I live....running.

      This just made my short list. 2-3 went away suddenly, so thinking the gasket blew out.

      If the valve body needs to be gone into (or worse), it'll do the Shift Correction as well.

      Well, its open and, metal bits...argh. Looks like it's getting everything (rebuild and shift kit) and probably converter if I don't see where the magical bits came from....in additional to the expected gasket and servo.

      Thanks for the thread, been a good guide so far.

      Total damage: Converter ate itself, sent metal everywhere.
      New Torque converter
      New front planetary
      New OD planetary
      Complete rebuild kit (Bands and all)
      Shift kit
      Servo sleeve

      Farmed it out, but again, this thread was super handy for having an intelligent conversation with an above average shop. I think it helps to be able to talk with them in the same terms. As an aside, 3 other explorers there at the time. :p

      Unless you have broken hard parts, bad torque converter or bad solenoids pack

      the following is what you need
