I'm gonna be having my 4l60e rebuilt soon. I need it to hold up to about 450/450 n/a plus a 150 shot. Won't be ran at the track often. Maybe once every two months. But hoping for some street encounters.
Do you have a list of upgraded parts you can recommend?

-Wide rear sungear bushing
-wide rear stator support bushing
-Beast sunshell
-borgwarner dual cage spray
-Sonnax HD sleeve kit for the input drum
-Billet forward piston to go with the sleeve kit^^^
-Gasket and seal kit
-Standard width carbonite 2-4 band
-Corvette servo for any stall smaller then 3600 and diameter bigger then 9.5in.
-Billet 2nd gear servo for high stall 3600+ 9.5 in.
^^^Reason is because the billet servo hits hard, with a large diameter stall (low stall speed) this only makes the servo hit harder and in turn breaks output/input, and sprags.
-For trucks/towing/ or WOT 4th gear pulls get the billet 4th servo, if you do not run your car in OD then its not needed. Very good idea for a heavy truck
-I like the 3-4 Zpack, or the 8 set alto and kolene steels work great.
-sonnax .490 boost valve
-Sonnax HD2-3 shift valve, allows sprag support when you race in D position vs OD
-TCC code 1870 fix valve to feed the converter clutch full pressure( a must on any rebuild)
-High rpm pump slide spring for shift points above 5,800rpms.
- drill 2nd and 3rd gear feed hole to .093 with new transgo separator plate.
-5 pinion planetaries are good only if they are OEM, aftermarket planetaries are weak. Same thing goes for aftermarket reaction shafts..seen those break,,stay OEM here.
This is usually the build I do for local people who have 400-450 rwhp in a Car...
For trucks or anything over 500rwhp The billet input and output shafts are a good idea.
Always remember driving habits play a big toll on transmissions.
WHEEL HOP will kill internal parts fast, so make sure your sus. is dialed in.
Slicks had a softer sidewall and can reduce shock vs drag radial.
Trucks-- 4.56's vs 3.73s will help with heat and stress of hard parts. Plus you can set up a slightly softer 1-2 shift to prolong parts as well.
Cars-- with 26in tire, I like 3.73's always works well
Remember big killers are....wheel hop, heat, hard shifts, pumping the gas while in gear......all driving habits can make a big difference

silverz28camaro,
I would like to know more about your home made trans tools. I'm picturing in my head how to build a compressor using threaded rod, washers, nuts and some bar stock. I suppose I could measure and rig it up as I go.
What kind of snap ring pliers do you use? I got the input drum out, but cannot go any further into the trans because my snap ring pliers won't fit to remove the next snap ring.
Thanks

I have a 4l60e transmission that has the same seal around the pump as yours... do you know what the part number is or where I can get a new one? I have a 2002 trailblazer that the previous owner had the transmission replaced in it, and its a newer model transmission with this seal, and I cant go by my year model trailblazer, so I cant find this seal anywhere, the dealership gave me part number 24226315 but its just a rubber wedge type seal, no metal... My transmission is leaking from this seal, so if you know anything about where I can get one, or how the rubber seal installs, please help.. email me at chrisbarker4813@yahoo.com, thanks.

Look up the part with this site^^ Has nice pictures and 'whats it fit feature".
Info from this Delco site on front pump to case seal
2003 - 2013 = 24226315 metal reinforced
1982 - 2009 = 24210605 old floppy seal
Alot of overlap in model years, so depends on the actual model. I think they gave you the right PN, but the wrong part.
... or the site is possibly wrong.
