A727 Rebuild kits redux - Rebuild kits everywhere (62-70 vs 71+)
Hi FABO,
I spent a little more time grinding through rebuild kits and websites to get a better understanding and selecting a kit (Beware my mental rambling).
I made the following assumptions:
1. All major hard parts in my case can be reused.
2. I'm focusing on consumables and should do's.
3. Looking at 62-70 A727 kits
4. Take advantage of having the case open.
Baseline
To help get my head around the configurations I began by randomly selecting Rebuilt kits in three levels stock, street, and HP street (my target build level) from various vendors to get a sense for which components seem to consistently show up in each kit respective to their level and then I omitted the components that didn't (I'll spare you the gory details). The short of it is that I broke out the components that will make up my overhaul into 3 categories:
- Baseline Kit
- Should do's
- Need (this bullet reflects damaged or worn components that were identified after opening the case that need to be replaced but didn't fall into one of the other two categories)
I decided to use the Cope Racing Transmissions catalog to illustrate and build the kit for my overhaul since they seem to have a good reputation and their catalog descriptions fit my format.
Components for the build
Baseline Kit
I used CRTs 727 Rebuild Kit-Street High Performance 62-70 as my foundation because it covers most of the common components found in rebuild kits at this level. The kit includes:
all seals, gaskets, o-rings, lip seals, sealing rings, 4 thick grooved Alto red eagle clutches for the front drum, 4 thin smooth Alto reds for the rear drum, 7 Kolean steel plates, filter and a teflon ring kit. Will work with high performance motors using automatic shift or manual valve body. This kit fits 1962-1970 727 torqueflight transmissions.
Next I added the following components from CRTs catalog to the Rebuild Kit to finish the parts list:
Bands
727 Front Flex Band Red Lining
727 Low Reverse Band Red Lining
Bushing/Washers
727 Bushing -Master Kit 62-70
727 Washer -Master Kit
With the baseline addressed I moved on to should dos.
Should Do
Line fittings
727 & 904 Line Fittings - AN Fittings 1/4 pipe to -6
Neutral saftey switch
727-904 Neutral Switch Short
Shift Kit
TransGo FT-2 Race/Automatic kit 66& up 727-904
Lever
band lever (4.2)
SPRAG
727 Bolt-in-Sprag 1966-up
Conclusion
What I learned is that a rebuild kit is a baseline regardless of the supplier and that components vary somewhat. Its important to choose quality components for the Kit and the supplemental parts. I never did find a Kit for 62-70 A727s that also included the master bushing/washer and bands (the closest I got was at bulkparts.com but it was for a 71 and up 727). I guess putting a big kit as comprehensive as that together doesnt make sense from a business perspective. Especially since each rebuild has to be taken on an individual basis. Oh and there is a subtle yet important difference between the 62-70 and 71 and up transmissions.
Still looking for your thoughts on the topic, Let know if missed anything
Thanks,
