Hi folks,
I have to rebuild my 4 R 70 W complete. I don't have access to these Special Tools, E. G. Lipseal Protector and others. Did somebody perform a complete rebuild without theses tools and how did it go. What tools did you use instead or what tools did you build?

Any suggestion would be appreciated.

I've taken apart and re-assembled a 4R70W using basic hand and air tools, snap ring pliers, and a hydraulic press. Everything went back together fine and the trans worked with no issues, so if I had one that was having issues, I wouldn't hesitate to pull it apart and investigate again.

When I built my low mile Mustang unit I only upgraded the clutch packs and added a spiral lock ring for the MD, All I used were a few flat blade screw drivers, good snap ring pliers, C clamps, an in/lb torque wrench, and pretty good knowledge of what I was doing.

Okay sounds really good but how did you check the endplay of the pump
i know this is tricky and i would need different trustwashers do make it right or the tranny burns up after a while

any ideas???

The one I did wasn't having any pump issues, just started slipping in OD, so I never took the pump apart. I'm not a transmission expert, I just can figure stuff out from messing with it, so basically the trans came apart, I kept everything in the same order it came out, it got new clutches and a new OD band, and and it went back together in the same order, and everything worked. I figured if I screwed it up I would only be out the cost of the frictions, and if it worked, I would save having to buy another trans or the cost of a rebuild, so I gave it a try and it worked out well.

First of all your 94 case & it's poor Hard Parts are generally deemed not worth rebuilding - Consensus would be to find 98 or newer & if low enuff miles you may want to roll the dice & forego rebuild - You DEFINITELY need a newer than 94 TC or you are completely wasting time & LOTS of effort~! -

For Rebuild you need TIME - & Yes you'll need a hydraulic press or at least a Piston Jack you can wedge into an area at some point - Some thin plastic Shim stock makes a great Seal Protector - Some Plumbing Parts fm Hardware Store make great compression Tools when mated with allthread & washers - You WILL want to check end play for Thrust Washer & there you need a proper length staright edge & at least a digital calipre or a depth Mic & some GOOD eyes - An Engine Stand can be tweaked to get the tranny vertical as you'll need that at final build point for sure - My BEST advice is buy your parts fm Dirty Dog, the little Screwdriver he sends you is WAY helpful & more importantly so is he - Some jerks buy all their stuff on Ebay then take advantage of the D/D & Darrin... don;t be that guy.

The accumulator and spring problems are well known, just buff out the sides of the bore with a scotch brite pad and use the updated accumulator piston in both the 1-2 and 2-3.

Every clutch drum has a piston in it that have seals on them. Without special tools you cannot change those seals. There are some work arounds but if you cannot do it the right way you probably shouldn't be trying to figure out how to do it the wrong way. Meaning hopefully they are good and you can leave them alone.

frank, you be wasting your time with that tranny; it won't fit your LX.

The tailshaft will need to be swapped, and other stuff.

Search around, all the info is here somewhere.

Or, get DirtyD0g to build you one.
