FS: Century Stage 4 4L60E/Circle D converter I'm selling my 4L60E out of my 99 SS. This was a Century Stage 4 that has been freshened up by James Lovelady. I put it in my car a while back and put about 1k miles on it before pulling the motor and changing my setup. The transmission works and shifts fine, I'm only selling it because I'm swapping to a 4L80E.
I'm no transmission connesseur by any means, but when Lovelady pulled the transmission apart, he said it had a bunch of really nice parts in it. Only thing I can think of off of the top of my head is a billet servo, but like I said, I know **** and zilch about transmissions, LOL. All I can say is it performed nicely behind a 500hp setup
I'm also selling my Circle D converter. This is a billet converter that I had sent to Chris to rebuild and never wound up putting it in the car, so it has never been ran at all. It was built to be between a 3c and a 4c and stall at about 3500 rpm and was built tight for nitrous
$1800 for the transmission
converter - SOLD
Local pickup only, parts are located in Huffman, TX

To the top. I've had a couple of people with interest, but no done deals just yet.
Here's some info from Century on what the stage 4 has in it:
•Transgo 4L60E-HD2 Shift Kit (including Century's internal modifications)
•HP 3rd clutch piston Return Spring Kit
•13 vane pump kit, clearanced to spec.
•Hardened Pump Support Rings & HP Pump Slide Spring
•Corvette 2nd apply Servo
•Alum. Accumulator Piston Kit (replaces plastic ones that tend to crack)
•Century HP Wide Band (3/8" wider than OEM w/High Carbon Fiber linning & reinforced strut ends)
•Reconditioned reverse input drum for maximum surface contact area of HP Wide Band
•Billet Super 4th Servo (firmer 4th apply & longer band life)
•Century HP 3-4 Clutch Kit: Special Alto Red Eagle® Racing frictions, Koleen steels, pressure plate & snap ring. Increases clutch count from factory weak 6 to awesome capacity holding 9! A must for any HD/Performance 4L60!
•HP Beast sun shell
•New 29 Element H.D. Input Sprag
•5 Pinion Rear Planetary Gear (25% stronger than 4 pinion gear) This is a NEW G.M. component which is more expensive than the inferior, unreliable foreign made units
•2-3 Check Valve Kit: improves timing between 2nd band servo release & 3rd gear apply
•Sonnax® HP 2-3 Shift Valve Update: Keeps the overrun clutch on when the shifter is in D3, takes the load off the input sprag for increased life when racing or driving "spiritualy".
•Reverse Capsule Update: decreases bleed oriface size in piston for better reverse engagement
•All clearances & end-play set to our performance specs
•New Delco Shift solonoids
•HP Input Drum w/reinforced alloy sleeve & Modified Overrun piston.
•Billet Forward Piston
•Cryo-Treated & Shot-peened Output Shaft
•5 Pinion Front Planetary
•Rollerized Reaction Shaft Kit
•OEM Steel Deep Pan
