Rebuilding the trani

[Rev-It-Up]

I have to tell you guys...this is great stuff!!

Bushing is fine. Take those clutches out of that drum and lay them out.

They look smoked. Pressure plate (top plate against the snap ring) might be warped.
This tranny had to have been slipping BAD!

bad isn't the word....total loss of 2nd gear.

The drum we have been talking about is reverse and third. It shouldn't have had a very good third either.

I got 1st and 3rd all the time, no 2nd.  In fact, I had to thromp the gas so hard in 1st that it would roll through 2nd and straight to 3rd just to get around the no 2nd gear thing.

Here's some more pics.  Servo valves look good as you can see in the pictures.  I was trying to knock out the clutch (??) and all the bearings and springs fell out before I could take a picture of it.  is that bad??  I hope not.  But the bearings look smooth, I have to inspect all of them, but most look fine.  The book says to use a knockdown punch to get the assembly out of the case, but I don't have one, so I've tried using a socket that is slightly smaller than the pin size and hitting the socket, but the assembly hasn't budged.  Any ideas?

DO NOT TAKE ANY MORE OF THE SPRAG OUT OF THE BACK OF THE CASE!!!!!!
This part stays in there

[tactransman]

Save your rollers, I will be sending you new springs for the sprag

Point taken.....LOL.....so what's next then?  The book had me taking it out of the case, but I'll listen to you of course.  Should I remove the large snap ring on the direct drum and take those plates out that are worn?

Ok, I'll save the rollers.....

[tactransman]

Yes , take the clutches out of both drums. You have to watch that book that you got, it is for performance stuff and it is 727 only. They are wanting you to knock out the outer race for a "bolt in sprag" install. A 904 outer sprag race is riveted to the back of the case (very hard and time consuming to remove). No need to change yours , it looks like new!

Ok, here's the cluthes from the front drum.  Looks like they're spent.  Also, look at rings 005.jpg, it looks scorn, but it feels smooth.

[tactransman]

Yup, there done. I bet that pressure plate is warped. The 5th picture is normal, nothing wrong there.
Are you going to be able to get that spring compressed? (SAFELY)

[RDF]

ok, here are the rear clutches.....they don't look half as bad as the front.  What I did notice was the front drum, how torn up it was on the outside, check out the pic that says front_drum.

You can probably run some 220 sand paper(if you ever found any) around that drum and clean it up. It is hard to tell from the pic how bad it is. You need to lay a straight edge across that direct drum pressure plate to see if it is warped.

cost for a new one? my book showed me how to get that bushing out without a spring compressor, it said you can use 2 c-clamps, which I have, but I haven't taken it out.  also, do I disassemble this part (don't know the name of it)?  My book is useless from here on out, all the parts seem different and not what's in my trani.  They mainly talk about breaking down that front sprag that you want me to leave in.  The next section talks about the valve body.  Is there anything I need to do to that besides install my kit?  Should I disassemble the whole thing as well?

[tactransman]

If you use two C-clamps on that skinny 904 retainer, they will probably slip off and it will get ya! That is another place in the book where it would be fine for a 727 , not a 904.

I figured so, that's why I didn't use them.  So what's next?  Do I take apart that part in the above pic or leave it alone?  Should I tear apart my valve body too or just install the kit?
