Rebuilding the trani

[tactransman]

Bob, the pump halves have to be lined up on the outside edge also not just to get the bolts started. If the halves are not centered together the pump will be tight going in. (you can check it in your empty case with the pump outer "O" ring removed to see if it goes in OK). The forward drum is the drum with the other set of clutches in it, did you get it built?


Rob, he needed a direct drum so I took the seals and the clutches out of his kit and built the drum before I shipped it all to him.

I got the drum you sent, I put the clutches in the rear drum and all went well.  I'm off to advanced auto parts to get a retainer clip that just broke on my valve body.  Be back in 20 minutes. 

BTW, got that filed out it looks good.

That's great that you did his drum , Terry, but did he know about the other piston in the rear drum?

I'm telling him now, Bob, that other drum (forward or rear) it has a piston with seals in it too. Did you change the rubber lip seals in it?

[RDF]

Sorry I took so long to respond....neighbor came over w/ a bottle of champagne to celebrate new years.

I haven't seen the rubber lip seals yet, but I will as soon as I'm done with the shift-kit.  We're doing great on it, on page 4 0f 7, skipping page 6 (as noted by big T.).  Will post more progress soon.  I'll be at this all night, till midnight atleast.

Bob, the seals are on this piston, remove the bottom snap ring (wavey one) remove the diaphram spring and remove piston. There is an inner and an outer lip seal on the piston. Easy to take apart and reinstall, just don't cut a seal on reinstall. I will be at some friend's house till later, any questions post them and when I get back I will answer them.
HAPPY NEW YEAR!!!!

[RDF]

ok, Happy New Year to everyone as well...

I'm 99% sure I changed those.....but I will check again to make sure.  I've changed all ring seals that are visible to me and accessable.

The shift-kit is complete!  We're on step 7 which is the springs in the servo valve and I may be missing something because it's late, but I don't see any shim to use??  I'm gonna take pics of the directions and post them for you to view.

[RDF]

Good thing I checked.....I didn't change them, and those were the two rings I didn't know what to do with!  They are in and back together now...

[RDF]

Ok, I'm off to bed, it's been an extremely long day for me.    Here's the pics of the instructions for the shift-kit.  Also, a few ?'s. 

1.) See leftovers.jpg, that is what I have left of the master kit.  Am I missing some places to change seals?  Looks like there's 1 or 2 that still need to be placed (the yellow one??). 

2.) When putting the gaskets on, should I use anything to seal them or just put them on?

3.) Would you happen to know where the part goes on the valve body in vb.jpg?

That's it for now, I'll be at it tomorrow morning! 

[tactransman]

Metal plate goes with the two very top screws out of the four above it in your picture.(holding the seperator plate only)

 I see that they don't say to shim a 904 rear servo , but I would, just like it says in the 727 area,727 shim should work for a 904 also.

Nothing on the gaskets, keep them dry.

All left over seals look fine except the manual shaft seal ,(greenish color) it goes around the shift selecter shaft in the case ( 15/16 deep chrome socket works as a good installer after the valvebody is installed.)

[tactransman]

I found a pic in the Archives for the little plate location,(different year so omit the bottom hump on the plate in the pic) that is where it goes.

[RDF]

Sweet.....I'll put that plate on, then put the shim in and then this beast is going back together! 

[RDF]

ok, trani is back together, couple of worry-some questions....

1.) Should I be able to turn the shaft from the rear?    I didn't put the extension housing on yet so the rear shaft is exposed and the front servo is not in.  The front band is on, but not tight with the lever b/c the front servo isn't in.  I didn't want to put it all together only to find out it's all got to come out.    One thing I did try was removing all the bolts from the pump, but leaving the pump in and the gear turns.

2.) My endplay is 0.  The shaft does not move at all, in or out.   

I've tightened the pump bolts and the drums and things seems to go together smoothly.  I did put the small thrust washer between the output shafts and held it in place with a little bit of grease.

[RDF]

Ok, I think I answered my own questions.....I took it apart again and noticed the small thrust washer had slipped.  I put it in with a little more grease and it seems ok now.  I've got free movement of the shaft both rotating and end play.  Do I have to check the end play to see if it's the same as when I started, even though I was missing the thrust washer from the start?  Won't my readings be inaccurate?

[tactransman]

First of all, you didn't hurt the thrust washer when it slipped ,did you?

No you don't have to check end play, I just hope you got all thrust washers in the right place. Your endplay will not be accurate and you cannot tell if it is all together right until you have the extension housing on and tight to the case with the snap ring popped into the bearing groove. ( that's why I was having you do that first in the reassembly steps)

 The output shaft has to be held in it's proper location by the output shaft and rear bearing/snap ring before you can check it.
