Rebuilding the trani

[JCWCuda]

Hey Guys thanks for the refresher course here  it's been about 15 years since i had 904 or 727 apart .And a MERRY CHRISTMAS to you guys and your Familys

Nothing new on this end.  I'm waiting on all the parts to come in that I need.  They should be here by Saturday, so I'll start back up then.  I may do my shift-kit on Friday, but we'll see.  I'd like to do that last, that way I have everything off my bench except the trani and valve body.  Seeing all these rice-burners around town makes me want to get this back together  and go tear some horror.     

Here's the list of parts that I needed:

Qty.  Part description
(1)    Master rebuild kit
(1)    Converter (rebuilt) 904, 360 engine
(1)    Intermediate "2nd" band
(1)    Reverse band
(2)    Thrust washers 1 for the pump and 1 between drums (same part)
(1)    Thrust washer for between input and output shaft
(1)    727/904 Manual
(1)    Filter
(1)    Pump bushing
(1)    Extension housing bushing (next to the rear seal)
(1)    Sprag spring and roller kit
(1)    Direct Drum Pressure plate
(1)    Direct drum with new bushing


Can't wait to start putting it all back together!

Bob, is the case and stuff clean enough for ya? If not, you can put it all back together empty with a couple of bolts (case,ext housing and pan) and take it back to the car wash for another oven cleaner treatment.Make sure it drys well before painting if you are going to paint it.

 Paint that is cheap and descent looking is : spray it first with a couple of coats of Wal-mart brand silver/aluminum,let it dry for about 30 minutes,then cover that with an light, even coat of dupli-color engine clear (also at Wal-mart).  Then paint the pan black,looks good together.

That's a great idea, but I probably won't have time.  The case is clean but I'm taking the kids to Animal Kingdom tomorrow during the day, then going out to eat (without the kids!)  tomorrow night, then Friday I am expecting my parents to come to town (from Boston) around noonish.  As soon as my dad sees my car torn apart, he's gonna throw on his old clothes and start turning wrenches, I guarantee it. 

One ? I have for you.....before assembling any of this stuff, should I clean it with carb/intake cleaner and then dip in trani fluid to make sure it's all clean?    If it's not clean and the before mentioned cleaners aren't good, what should I use?  I've got all the parts under clean rags right now, but I'm sure some grease may get on it during assembly and what not.

The only thing that needs transmission fluid on it is the friction stuff (bands,clutches) dip 'em for about 15 minutes, then let them drip into a pan. Do a final clean with non-clorinated  brake parts cleaner, it evaporates better. Use wheel bearing grease to hold washers in place. Put tranny fluid on the pump gears when you assemble the pump. Did you get some big hose clamps to screw together to make an aligner?

Enjoy those kids, you sound like a GREAT Dad!

Yes I did get some clamps.....thanks for the great dad comment.  I try to enjoy my kids while they are enjoying me!    I know they will come to a point in their lives where they will want to spend more time with friends than me, which is all part of growing up, but I still try to spend as much time with them as possible.  I'm so excited that my daughter wants to help me work on the car (she calls it "the beast car").    Can't start them young enough to learn about cars, that's for sure.  She gets a kick out of it when I put her in the passenger seat and take her for a ride around my gated community.  She always tells me "hit the gas, hit the gas"  as she's haning out the window!  What a blast!

Ok, got the converter today, so I'm off to tackle this thing.  I may have  afew questions here and there so stay tuned..... 

[RDF]

Terry,
How does the seal and bushing come out of the pump?  Can I just knock it out with a screwdriver and hammer?

[tactransman]

Yes, new bushing should be close to center of the bore depth.

[RDF]

ok, pump is back together.... should I use a torque wrench when putting the bolts back on?  Also, what order does the springs and rollers go onto the sprag?  The book doesn't show a clear picture of this.

[RDF]

I think I figured out the springs, but here's my biggest question.....The springs look to be beveled on one side.  Which side should this face?  The Gear side or the sprag side?  Pic 002 is the way I have them in there now, with the top of the picture towards the gear and the bottom towards the sprag wall / trani wall.

[tactransman]

Either way will work. Compare it to your old pic also to make sure you have the springs and rollers layed in the right direction.  Torque wrench is a good idea.   Inner sprag race needs to be centered in the case or rear drum will not go in.(springs will be compressed the same amount)

That's one of my issues is that I don't have an old pic to compare to.  At the time, I was trying to tap out the rods that hold the sprag in (the 727 book says to do that) but you said they are riveted in.  But when I was trying to tap them out, the rollers and springs fell out.    Lemme get you a pic of it now, I think it looks good.

[RDF]

upon further investigation, I have a few rollers out of place (see pic below).  I will fix those now and repost the new pic.  Do you agree?

[tactransman]

Yup, get all the springs compressed evenly and you are good to go.
