Making this thread showing the progress of my 60E rebuild. Out of all the transmission guys on the site not sure if anyonne has posted something like this. Also not sure if you can consider this a "how-to" but it might be close. I definatly dont consider myself an experienced transmission builder by any means, but iv been through a few during school and figured I would test my skills on my own transmission.

Parts list:
Corvette intermediate servo
Sonnax billet overdrive servo
Double cage 29 element forward sprag
Low/Reverse spring roller
Alto red low/reverse clutches and Koleen steels
Alto carbon oversized 2/4 power band w/ reinforced anchor
New input drum/housing
Rebestos blue 3/4 clutches and steels
Rebestos blue overrun clutches and Koleen steels
Beast reaction shell
New reaction sun gear
GM rear 5 planetary gear set
Rear carrier ring gear
Thrust bearing kit
Sonnax boost valve
Billet forward accumulator
Billet 1-2 accumulator
EPC Solenoid
Superier valve body shift correction kit
4L65-E overhaul kit(gaskets,seals, ect)
GM updated valve body seperator plate
Billet 300m output shaft
Billet 300m input shaft
Billet input drum sleeve & piston
RPM high-rev spring kit

More parts will be added as I go. This is what I need/want so far


-TEARDOWN-

Heres what im starting with. 04 AWD 4L65-E. Guy I bought it from said low/reverse is out.

Posted Image

Band anchor removed and removing 2/4 band. Band didnt look bad at all
Posted Image

Reverse input clutch drum and input housing set aside

Front planets removed from input gear
Posted Image

Reaction sun shell
Posted Image

Reaction shell removed
Posted Image

Reaction sun gear removed
Posted Image

Here is where the sun gear splines with the reaction shell. This is one of the many weak points in a 60E. Alot of times you will see the collar sheered off the shell
Posted Image

Here is the low/reverse clutch support assembly, roller sprag and race, L/R clutch pack, and reaction carrier assembly (or rear planetaries). Also output shaft

Retaining ring removed

Roller race
Posted Image

Sometimes the low/reverse assembly gets stuck in the case. Giving the end of output shaft a few hits will free it up.
Posted Image

Pull out L/R
Posted Image

......and the carnage begins
Posted Image

Here you can see the ring gear had got really hot
Posted Image

Toasted clutches and steels

Self explanitory

Got inspecting the rear carrier and found all 5 planet gears with chipped teeth. Damn it!

Retaining ring
Posted Image

Reverse clutches and steels removed
Posted Image

Now on to the input clutch assembly. Here is the 3/4 clutch backing plate retaining ring
Posted Image

3rd and 4th clutches and steels. Another weak point in the 60E. You can see the clutches are burned and the steels have got hot. Usually caused by shifting from 3rd to 4th at WOT in high horsepower applications, or towing.

You can see the clutches are burned and the steels are bad

Another weak point in a 60E where the input shaft and input housing are joined the sleeve shatters damaging the shaft and housing

Looks like you're doing a very good job. Excellent choice of parts for your build. Odd that you burned up a Low/Reverse set of clutches. Those are very rare to have fail. Either way, great pictures and great choices on parts. I currently have a few apart at work and one of those is a top notch type build as you are doing for a GTO with a 500RWHP 402 inch setup with a 250 shot to go with it. Thanks for posting pictures like this, it's alot of work and you are doing a great job with it. I might post some of mine one of these days.

:cheers: :peelout:
