I am still deciding for a 1980 corvette to get a used LS1 and 4L60e and rebuild them.
Or look at the costs and go for a 2006 - 2013 L98 (LS2 in Australia with LS3 heads and weaker cam)...

My diff has a 2.87 gear in it so it would benefit from the better gearing of the 6l80e


Can you help me out with part list so i can see how much it will cost to do the 4l60e correctly.
No more than 400RWHP would be put in it, and some WOT but mainly a cruiser ..

Here is what i have so far

Beast Sun Shell Kit
Transgo reprogramming kit 4L60E-HD2
Superior PERFORMANCE Shift Reprogramming kit K4L60-E (this needed? Upgrade to transgo?)
Sonnax Rear Stator Support Bushing 77002BT-01
Corvette 2nd Gear Servo
Borg Warner Hi-Energy carbon 2-4 band 27363BW
Sonnax pressure regulator spring 77917-10
Sonnax 4L60E Boost Valve and Spring Kit .490 77898e-3k
OVERHAUL GASKET & SEAL KIT W/MOLDED RUBBER PISTONS A74960EK

What do i need for clutches, friction plates etc?
I read to get Raybestos Zpak 3-4 but what else is needed



Other "upgrade" parts i read about are
Upgraded Sonnax Forward clutch piston
torlon check *****
replace anti - clunk spring with a case saver
Sonnax Pinless Accumulator Piston Kit
1-2 accumulator springs
Accumulator servos 1-2 and 2-3
BW input sprawl double cage
Bushing kit

^ Am i doubling up on parts with any of that list?
Any of them necessary ?


Thank you ! Part numbers would be awesome if you have them.
