[QUOTE=mrvedit;16343387]I think most of the failures are people taking pre 2002 (and especially pre 1998) 4L60E and expecting them to survive behind their 400+HP LS engines. Without a rebuild and upgrades they WILL NOT.
The parts that should be upgraded are mostly no-brainers and only cost an additional $400:
1. Sunshell - use the Sonnax Smartshell ($75) or The Beast ($50)
2. Borg Warner dual-cage Forward Sprag ($40)
3. Corvette Servo ($20)
4. 5-gear Planetaries - GM/ACDelco only, but cheap now ($70 and $80)
5. A quality 3/4 clutch pack with 7 or 8 frictions. Different builder have different preferences, but figure $80.
6. Transgo HD2 Shift kit ($80). The Sonnax is probably good too but a bit more ($140).
are these parts available in a kit?

1. A wide band SHOULD only be used with a brand new reverse drum. Else the "ridges" left by the old narrow band will cause premature wear down the wide band.
2. For the 3/4 clutch "Raybestos clutches" means nothing as Raybestos makes everything from stock to race-only clutches. Also the number of clutches is important - most builders recommend 7 or 8 for street/strip use.
For example "7 Raybestos GPZ105 with .098 Kolene steels" would be good.
Or "7 or 8 Alto Red Clutches with Kolene steels" would also be good.
3. All new GM transmission use a 13-vane pump which reduces oscillations in the line pressure. No big deal.
Claiming 450HP for that combo is reasonable. For more power:
4. Upgrading to the Sonnax Smartshell or The Beast is recommended.
5. Upgrading to the genuine GM/ACDelco 5-gear planetaries is also good.
I don't know if Lou's price is good - it seems a bit high, but then includes things like new solenoids that many other kits don't include.

Hopefully I didn't miss anything obvious here. (I'll edit it if I did.)
Some rebuild kits incude many/most of these parts.
There are quite a few other optional parts, but it is more important to:
7. Have the valve body rebuilt by a pro, or get a rebuilt one.
8. Install a new separator plate - Transgo makes a good one.
9. Replace any plastic accumulator pistons with metal or Sonnax pinless.

They are available on Amazon:
24241244 5-pinion rear carrier/planetary - $71.50 today
24241248 5-pinion front carrier/planetary - $63.50 today
We just bought several and they are genuine in sealed ACDelco boxes.
HOWEVER, my local trans build and I have discovered that these latest 5-pinion front planets also require a matching reaction carrier and matching bearings. See this post:
https://ls1tech.com/forums/automatic...n-planets.html
Especially my post #12.
Still the entire kit of matching parts is less than $150.

Thanks. I picked up a set. What do guys recommend for fiber and steels? I was thinking Alto Red Eagle fibers and plate kit. Or is the Raybestos blue plates worth it?

Let me make an analogy (and correct me if I am wrong)
Stock frictions are like basic tires - designed to last a long time with easy driving, but have less traction.
High energy frictions are like performance tires - designed to last reasonably long with much better traction.
Red frictions are like drag radials - much better traction, but the soft compound won't last all that long.
Blue frictions are like all-out racing tires - fantastic traction, but the very soft compound probably won't last even one season.
I don't have the experience to justify this, but if there were one "best" everyone would use it. Instead there are tradeoffs and the "best" choice will depend upon how you use the car. IMHO blue frictions are for race-only vehicles.

Ended up getting a kit from trutech with raybestos stage 1 kit for fibers and steels. Also did the 5 Planetaries front and rear plus supporting parts, Sonnax smart shell, Borg Warner dual cage sprag, 4l65e low roller, wide 2nd band, new Reverse Input Drum, Input Drum Reinforcement Sleeve, Corvette servo, Pinless Forward Accumulator Piston, trans go shift kit, billet forward piston.
Thanks to Mrvedit for the good tech info and part numbers. Also thanks to FLT Trans for a fast turn around. They pressed the sleeve on the input drum,assembled the low roller, and got me the right sprag after PATC shipped me the wrong one.

Sounds like you got a excellent combo of parts. I haven't used a billet forward piston yet (with the Sonnax reinforcement sleeve), but will in the next time.

Hey my man! If you are wanting to do the job yourself i understand, just remember that you need the special tools to do this job.
If you needed help with a new re-build; a 4L60E Level 2 rated for 500HP with converter and free shipping, waived core charge for $1475.00
You might want to look into a rebuild kit as well. Let me know what your application is for, and I can help point you in the right direction.

1. A 4L65E rebuild kit should be used; the ONLY(!) difference is
that is has 7 frictions for the 3/4 clutch.
2. The sun shell should at least be the upgraded/hardened GM
unit, which is standard in all '03 and later. The Sonnax Smart Shell is a better choice and cost about $75.
3. I recommend the Sonnax 4L60E-LB1 boost valve ($25) which will increase line pressure a bit across the board and tighten up the shifts, reducing slippage. The Sonnax or Transgo Shift kits are other options.

burnt 3-4 clutches R&R
the price could be any where from 500-3500
i just spent $750 for a 600hp rebuild.
i felt really weird about the build because the transmission hadnt even been run the a washer.
so i had my trusted transmission man look at it and he showed me mismatched clutches and used parts.
my transmission guy said he would love to rebuild my transmission for $750
mine was a running driving trans with burnt 3-4 clutches thats all that was wrong with it.

The reason the guy couldn't give you an answer is because there are too many reasons why the 3-4 clutches burn out. You could be looking at bad hard parts that are not parts included in even the most deluxe of renbuild kits. Been in the transmission business for a long time and actually taught at a major trade school. This trans took quite awhile to cover. Go online & look !
We look forward to any advice and technical advice you would like to contribute.
However, please minimize posting on old threads as no one wants to re-read them to figure out what you are contributing.
No big deal - I know it takes a while to figure these things out; after a search just keep an eye on the day of the last post.
Obviously informative posts on current threads are much appreciated.
Thanks.
