How easy (or hard) is it to rebuild a 727?

[426HEMI]

The secret that I have to tell is to soak the clutches and bands over night before putting the trans together.  Gets all of the air out of the clutch material.

Torqueflites are really easy to rebuild, I built mine up on my kitchen table in college.  They are very simple, and as long as you have a manual and take your time you should be fine.  I personally think building rear ends, engines, and manual transmissions are more difficult.  Just make sure you keep everything extremely clean.

   They are really easy.  Air checks can be made to insure that clutches and bands work before putting it in.

Thanks for the replies everyone! 

Hmmmm...I better get a manual and check it out.  Doable maybe?

You guys didn't need any special tools to rebuild the tranny?  Chryco mentioned a press to get the drums apart to replace the seals?

In order to compress the clutch drum pressure plate you will need a drum compressor which can be bought at Napa, alternatively you could rig something with a c clamp.  I bought a heavy duty compressor which can fit a vice and works on all sorts of transmissions.  It was about $80 from Transmission Parts USA I believe. They also had the lowest prices for parts when I did it. Besides that you'll need basic hand tools, a feeler gauge, snap ring pliers, and a slide hammer if you dont already own one.  Nothing too expensive or hard to find.

apparently the oil pump looked fine & was making just enough pressure to move the car but not enough tio lock the clutches up fully , costly mistake   

If you looked at it and it looked fine,it was probably fine.There is nothing to hide in them and I know you know a worn out part when you see one. 

The biggest difference between doing a Torqueflite yourself and leaving it to a "pro" is getting it to perform 100% to it's fullest potential. Getting one rebuilt and having it have a rev and three forward gears is possible by a do it yourselfer.

Oh and by the way,for a rebuild kit for a 727 to be $150 it would have to have everything included.(both bands,all thrust washers,filter,bushings,clutches,steels etc,)

Great info guys! Thanks!  :

Thanks Terry!  Now I know what to look at when I see the kit!

Thanks quagmire for the suggestion about the C-clamp!  I'll keep that in mind when I look at the manual.

You guys are the best!

I am not trying to hi-jack this thread, but how much more difficult would the A518 be over the 727?

[quagmire]

I'm sure Terry will chime in with the right answer, but I believe the only big difference between the 727 and 518 is the overdrive section.  From what I remember you do need special tools to compress the pressure plate springs in that section, they are under a lot of presssure.  But dont quote me on that it's been 2.5 years since I tore one down!

There is a bit more to building a 518 than a 727. Like Dan said,the front is basically a 727 but the stuff in the OD section is a little more complicated if you take the OD section ALL apart.

Is it possible to just seperate the OD section, then rebuild the 727 part, then reinstall the OD section without rebuilding it?  I know that would be a big risk if it is bad, but would be any extra work/tools to do that?

I wouldn't do it,there are things in there that need to be checked or updated.

That A528 tranny sounds like anice tranny!  Never heard of it before...now I know!

I won't, I was just wondering
