4t60e Performance Rebuild kit.

[3400-95-Modified]

Well I found one out there... I'm ordering it today and I spoke with the owner last night. The kit comes from Raybestos and the clutches are made specifically for them, they are a high energy type material and they are all matched up with the proper steels. It also includes o-ring and the seals and the gaskets.

I should be able to return my $60 gasket kit I ordered from TPUSA then so I can save some money.

I will update this thread when I receive the kit to show everyone whats included.

The website is www.levelten.com I found them on the Raybestos performance distributor list when I was trying to find a place that sells their Blue material clutches for the 60e.

Finally something that I can put in this 60e so it can hold up to the abuse!

Level Ten has been around for quite some time, and providing parts for the GM trannies. I remember hearing a lot about them over on GAGT.com several years ago.

I don't visit GAGT and I could only assume they've been around for a while just by looking at their website... BUT since everyone preeches 5-speed swap in a beretta and where I visit there has never been discussion about making a strong 4t60e... and finally I found this company as a provider of a 4t60e performance kit, hell they don't even come up on google when you look. I got lucky looking at the "performance section" on Raybestos website and actually they were the only ones on that list that covered a 4t60e.

I'll have to check over at GAGT and see what has been said about them.

As said though this is a clutch pack kit... They do not appear to have a VB for sale over the web. I'm getting this just to simply eliminate the chance of smoking clutches in my trans. Its better than using stock clutches and praying for the best.

seems there are a few things availible for the 60e...

Most of the talk over on GAGT probably concerns them modifying the 4T40/5Es, not the 4T60Es, but I know there has been at least 1 person that I can remember that got 4T60E parts from them.

Yeah, full rebuilt trans, full new trans, converter, pump and rebuild kit. I got the rebuild kit. And sorry But I will not pay 400+ for a pump kit unless it is including the valve body, because to be brutally honest our pumps are almost as simple as you can get and I can't see in ANY way in spending that much money to modify one.

I don't know if I have a picture to show everyone though. I'll look

And a 1k converter... That seems steep since I can probably have Yank, or PDQ modify one for a little bit cheaper than that... But then again I do not know what they do to it for sure.

EDIT
found pic of a pump...
It's quite simple, in one side and out the other... There aren't many passages or any valves in this that can be modified.

[bszopi]

If you search GAGT, there is also a company out there that made line lock valve bodies for some of the trannies... Not sure if it was just 4T65E, or 4T4xE, or what. I just remember it being available.

EDIT: transbrake, and it was Rossler

[IsaacHayes]

But you haven't broke yours yet... And the rebuild is pretty fresh.... lol

Let us know if your clutches were worn when you take em out. I don't think you had many runs though on the gas though...

I wonder if a build up 60 with these would hold up to loners motor. I wonder if it was the hardparts exploding in his trans. I've heard the clutches are really not the issue in these trans, it's the hardparts that fail with high power and with age you get burnt clutches due to other issues such as worn valve bodies, etc

[3400-95-Modified]

He said he was fusing clutches together.... but that was never verified...

Either way I'll post whats in the kit, AND what comes out as far as wear. Fresh rebuild also means I'm saving all the parts. Its got 2 years on it and about 15k miles... so its not THAT fresh... I really only intended on doing all the valve body valves that I bought and just inspecting everything, but since I found this kit I said F-it while I'm in there.... yeah you know how it goes.

I just want some nice strong reliable clutches in there so I can bump the line pressure some more and get a firmer quicker shift. I've also shimmed my spring block for the EP LSD to increase the preload

Never having rebuilt any ATs causes those of us who either can't or won't to admire those who can and do work on them. I toyed around with the idea of getting a busted 4l60e... just to dig around inside of it and see what all the fuss was about... until I spied this video and shied away. Way too many funky parts, valves and specialt tools to keep track of and harder than Chinese Math to keep it all straight.

If I was going to do one... I think I would have to have something like this to encourage me along and not FUBAR the project:

15k miles is still a baby... This isn't 1950's where you rebuild an engine/etc before 100k.... Hell now days things should last at least 200k. Even if you rag on it I'd say it should look like new at 15k... It's not like you are hitting it with a 100hp shot every day. My trans has to look horrible inside. I do not drive normal, I constantly go WOT so it's always downshifting... and with well over 200k it's seen better days. it still gets me places though. It does do some strange things sometimes but oh well. When it gives up I'll throw in a 40k one with some accumulator springs and enjoy a grabby 1st gear again... LOL EDIT: my miles are all city miles. I rarely go on the highway. Maybe once every 3 months for about a 15 minute drive.

[3400-95-Modified]

My cam bearings only had 15k miles on them... They were still baby's too...

I highly doubt I could build this trans with a stock kit, NOT oem parts, and then expect it to run 100k miles with the power I'm pushing through it.

My red car, well thats a different story... I left that alone ever since I fix a part in it after 06 Bfest... its been mated to a few different engines too, and I think the short time that it was mated to my hybrid it stretched the chain like a mofo... You can feel the slop in it now, and that chain probably does not have over 100k on it.

Yes the clutches should look like new, but with what I've done to it, ANYTHING is possible. I'm sure mine saw quite a bit more abuse than yours did.

Also why is it that I find a performance kit for a 4t60e (yes that was known about but not discussed) people rag on me still... Also if someone finds a performance part for a 3400 and goes to throw it in a 4k mile motor no one says "you just rebuilt it why bother" I'm trying to take what everyone calls the weak link and make it do something, rather than always being called the 4TsleezyE

I'm probably tearing the trans apart tonight to see what I have going on so if I need new pump parts I can order them. I did not replace the veins in this pump when I got it, but at that point it only had 75k original miles and they looked/measured good. And YES the OEM clutches then being driven by the owner before still looked new. I can't guarantee the replacements were the same quality though, and I doubt I'm driving it the same way she was, or even at the same power level...

[IsaacHayes]

Yeah but your cam bearings were sealed power and those obviously do not match OEM quality/durability.
Yours might have seen more abuse as far as power, but as far as driving it like an idiot, and actually looking bad inside, I'm sure my never been touched 200,000++ mile trans is the winner there.. .lol My chain has been loose forever. You can feel it "slam" when it takes up the slack a lot in town, like a bike chain that's loose.

I'm not dogging on you, just giving you crap. "You gotta break what you have first!" I probably wouldn't have the patience to take apart a trans with only 15k on a rebuild. I'd wait until it started slipping then throw in upgraded stuff. Props for having that ambition! But if you have everything out anyway now is a good time to do it though. And you've done it before so you know what's in store so it should go fairly quick.

As my friend says "yesssss, Spend that money!'

What brand clutches were in the transstar kit? I thought it was raybestos too? (but not blues)

[3400-95-Modified]

Yes, standard replacement Raybestos clutches. But as you noted I have it out, I'm doing it now, and when you break it then it typically costs 10x as much to fix, it's called preventative maintenance... In the end its cheaper, and a bit more intelligent.

To be honest next year I may pull the motor and trans again, BUT I will NOT be working on them, they will just be removed so I can gain access to some of the stuff in the engine bay I wish to clean up that I haven't been able to get to this year.

As well as fully coating the underside with a uniform material, rather than bed coating where it was needed and not touching the rest... looks cheap that way.

Never having rebuilt any ATs causes those of us who either can't or won't to admire those who can and do work on them.

Having never rebuilt and auto, but worked on many manual's I would have agreed with you 4 days ago. I purchased the technition's guide for my 4t60e TCC problem and have since studied it in detail. It is definitely many times more complex than a manual, but the manual has demistified its functions and I would feel comfortable doing a rebuild with the rebuild book for torque specs on everything. If you are interested in autos, I suggest you buy the book and study that instead of watching the videos. Sometimes they skip over certain things that can add to confusion later (in my oppinion).
