# 9 brg is ford part#E6DZ -7G178-A or timken # FH-58073
#7&8 are GM# 9436851 and the one for the front planetery is Ford # F81Z-7A166-AA
Changing any of the other thrust washers will not help as they are not loaded or shouldn't be .
# 9 -shorten the oneway race to 1.010"
#8- machine the rear hub to fit the O.D of brg & I.D .050" smaller thanI.D.of brg .050" deep, machine back side of rear planetary .030" deep x.050" larger than O.D. of brg
# 7-machine the frt side of the planetary .040" deep same o.d. of the brg ( the brg is .140" thick & the stock thrust washer is .062", most C6's have way to much endplay , you want to have between .030-.045 end play when done , the orginal thrust washer race on the sungear shell can be removed to get the other .040" clearance here if neccesary)
# 5 Front planetrary already has 2 factory torringtons all you have to change there is the one thrust washer , the planetary needs the snout turned down .010" approx for I.D. of brg to fit (planetary's vary here)then machine face .040" deep x .050" larger than the O.D. of the brg , on the forward ring gear hub machine a groove .058" deep the same O.D. as the brg and .050"smaller than the I.D( Note the .050" on theses is for oil inlet clearance)

All cut should be done with a good carbide cut as the pins that are being trimmed are tool steel

On the C6 when you roller-ize the planetary gears do you machine the stock sprag race in the back or do you substitute one from another trans, E40D?

This looks EXACTLY like what's been done to Noelke's C6's that he uses in his monster truck and it's never caused any problems at all in that application. What about the front planetary set having 3 gears is that really ok for a high horsepower application? At least two of his transmissions are like that 4 gears in the low gear set, 3 in 2nd.

Thanks for the pictures.

Dave ,I machine the stock sprag race, and the 3pinion planetery's are plenty strong , I've never seen one hurt ,now on the low ratio gear sets it's a different story I've seen the planetary's explode but I've yet to see a stock ratio planertary ever hurt

I do think Noelke broke a set of planetaries in one of his transmissions one time, I think it was the front set and it tore out the splines. It only happened one time so it was an isolated problem. I think the only hard parts he's ever broken have been an input shaft, a set of planetaries and a few converter sprags.

The C6 parts are amazingly strong!

Based on this diagram I included in this post is there anyway Frank or somebody that understand how to rollerise the c6 can show me on the diagram where new parts are going and parts need machining I know this can help me explain to my machinist and help other newbie to. would probably need to print off and re-scan if possible

Hi I maybe off topic a little but I have a newbie issue with a 1975 Valve Body and c6 trans,
I am wondering if I left a component out when I fitted the shift kit.
as I found this needle valve but am unsure if it even came from the auto. no spring seems to fit it nor no obvious seat for it to sit in.

Valve.
Any suggestions greatly appreciated. eg bin it...

Any chance you'd have a pic of the valvebody? Show the top of the manual valve . Some valvebodies have the detent in the valvebody, some are in the case . If I understand the issue you have the trans assembled? and there is no detent for the gears?? A 75 valvebody should have the case detent .

You in Australia too ?

VB from the top

Sorry I was waiting for a notification then realised I hadn't subscribed to the thread, as per attached pictures, thanks
I sorted the Detent the spring had just swung past the cam detent on the inner bracket. but I still need to know what the needle valve is for? Box is assembled
too thanks.

:eek: :confused:

Yes I just dont lnow myself either. If nobody has seen a needle valve like it in a C6 before it is going to stay out.
(one of those ones when you walk with the VB in hand from the auto to the bench and happen to look down seeing the valve on the floor... and then you think why wasn't I paying more attention... lol
:rolleyes:
Thanks for your fast reply all the same
Cheers
