A727 Rebuild kits redux - Rebuild kits everywhere (62-70 vs 71+)
Hi FABO,
Well the rebuild is progressing well, even if it is slow (mostly because I'm really taking my time to understand everything).
As a follow up I thought it be cool to provide an update.
Some points before I begin.
* The Video and handbook are valuable resources (a must have for any beginner).
* FABO members are very knowledgeable and have provided very solid advice
Once I had a handle on the parts, I sourced them from different vendors take a look at post 15 for the parts list:
Northern auto parts (http://www.northernautoparts.com) for the Deluxe rebuild kit by Transtar. When the Kit arrived I noticed the package read for 71 and up. I called the good folks at Northern and they said I was good to go with the 71 and up kit. I expressed my apprehension and they said that they would check on my concern and get back to me. While I was waiting for Northern to call back with an update I pulled up the Transtar website and when through the catalog. While on the website I found the number for their location in Edison NJ which is just 10 minutes from my work. I made a call to the Edison location and spoke with a nice guy there who explained that Transtar does not produce the 62-70 kit any longer and he suggested that I purchase the supplemental Kit containing the 62-up things I'll need. About 10 minutes after I wrapped up with Transtar Northern called back and said the same thing, they explained that is why the site indicate I need to purches the "K22950E-4" sub kit. All was good. So if you buy that kit keep in mind that you'll need to purchase the sub kit to if you are working on a 62-70 transmission.

Summit Racing (http://www.summitracing.com/) for the Transgo TF2 Shift Kit
I removed the tail shaft housing and noticed it looked good.
IT wasn't until I pulled the oil pan that I saw the pepto bismal... I don't know how long this trans sat out of the car but it looked like someone did a lot of work then let it sit.
Taking the assemblies out of the case went smooth (slide hammers are key).
This is when it started to get interesting and more expensive. As I disassembled the trans I noticed that there seemed to be a lot of new parts as if it was overhauled run for a short while then pulled and set aside. As I removed the Valve body the first thing I noticed was that the Accumulator spring was missing and the piston was free to slam up and down in the port. I also noticed that the Apply (Kick down) servo was not complete either. So Now it hits me that this trans was prep'ed for full manual Race application and I need to bring it back to Street Auto. I can't wait to look at the valve body but I think I know what to expect.
The Apply servo is missing the Piston and the outer spring (I picked up a new setup from (Pat Blais)
The Low/revers servo was left absolutely stock.
I removed the Overrun Bearing (Sprag) to replace it with a bolt in unit.
Disassembled the front clutch and notice that the frictions and steels looked barley used. Many folks have told me to replace them anyway since they've been sitting in water and well let's face it I didn't tear this down for nothing. This clutch was set up with the 340 spec 6 springs. I'll be upgrading to 12.
Moved on to the forward clutch and yess the material there looked the same as the front did and the bands for that matter. "shakes head"
I drilled a 1/8 hole through the case on the oil return port as described in Munroe's handbook to provide additional lubrication to the bolt in overrun sprag.
With the lubrication hole drilled and the metal shavings cleaned out I installed the bolt in overrun unit. I used the bolts to line it up and start it into the boss then finishing with a press. (A press isn't required but it sure makes it easier)
With the Overrun installed I reassembled (with all the new stuff) the pump, front clutch, forward clutch then did a [ame="http://s953.photobucket.com/user/alv1970/media/2013-09-03112844_zps7a9702e8.mp4.html"]2013-09-03112844_zps7a9702e8.mp4 Video by alv1970 | Photobucket@@AMEPARAM@@http://i953.photobucket.com/albums/ae16/alv1970/bth_2013-09-03112844_zps7a9702e8.mp4@@AMEPARAM@@953.photobucket.com/albums/ae16/alv1970/bth_2013-09-03112844_zps7a9702e8.mp4[/ame].
Here I wrap up the planetary, reassemble the drive line in the case along with the servos, then head on to the Valve Body. BTW I picked up an unmolested OEM 69 valve body (also from Pat Blais) which I'll use to install the Transgo kit.
Servos.. this is when I started using parts from the Transgo tf2 kit. The front servo goes in as it came out complete with 2 springs, piston, rod and retainer, except it has been cleaned, inspected and has new rings.
Rear Lo/rev servo is uppdate with transgo pieces.
Transgo restriction plug installed
New front band apply lever
Planet is set up and ready to go in...
The output shaft support was pretty well worn in by the lower ring seal of the governor so I ordered a new one from Whatever It Takes Transmission [WIT] (https://www.wittrans.com) It's not a big deal if you are setting up for full manual but since I am returning to auto and I have it apart why not replace it.
Low/Rev drum, band and planet installed in the case.
Next the Governor and bearing
Next the input shaft assembly (front and rear clutch packs)
Time to dry fit the pump and take total end play measurements
I'm stoked with this measurement
with a good read on the dial I put pump in with the new seals along with the tail housing then made the adjustments to both bands.
Next stop... valve body.
I hope to have a nice street setup when I'm done and I'm praying it all works and I didn't do something stupid! LOL
