Default anyone rebuild a 4l60E themselves?

was it very hard? will it be somewhat easy if im mechanically inclined?

will this be sufficient for a 97 4l60e that has lost reverse and 3rd? and will this be able to support decent HP (i only need it to support around 360rwhp right now but plan to go to a turbo setup in the future with around 600-700RWHP)?

the kit includes (multiple parts i selected)
complete Transtec gasket and seal kit
American made Alto clutches and band (will be using RED parts listed below)
Federal Mogal or Clevite front and rear case bushings
Sealed Power full ring kit and filter
ALTO RED EAGLE HIGH PERFORMANCE EXTRA WIDE BAND

ALTO 3-4 update Red Eagle High Performance Kit with
7 ALTO RED EAGLE .062" FRICTIONS
6 KOLENE .106" STEELS

how much HP could this handle?

My suggestion is do it only because you want to, a challenge. Don't do it because you are trying to save money, it will probably cost more if you factor in your time and the possibility of having to pull it out because of a problem. There are some DVD's and books that will help out. I have a rebuild kit on my website that is a good list to go by.

I would agree with Chris , If you want to do it as a challenge or just to learn , Great! If you are doing it to save money or if you need the car regulary. Probably a risky idea.

well i want a challenge as well as trying to learn and have a while to do it (still need parts for 5.3 swap most likely going in around the end of summer)

is there anything else that you guys would recommend i pick up? it will be getting a shift kit and cooler also and most likely a deep pan
what kind of HP would a build with these parts be able to handle?

Its tricky getting the return springs compressed. Not too bad other than that. Make sure you have a manual and get the specs right.

Yes, only do it if you want a challenge. For me everybody I know knew everything about an engine, but got scared when the transmission started acting up. So I wanted to see what was so "scary" about them. I started collecting factory service manuals, fluid diagrams, hydraulic systems, principles of operation, etc. They became the morning newspaper for me. The first one I did I didn't set the 3/4 clutches up right and burned em up. It's a apart in my garage right now. The 2nd has a year on it now as I drive it everyday. It's in a 4x4 that also sees offroad use. Other than a weird lock-up issue, I've had no problems. The third I just finished for my 95 Camaro Z. I went all out on it and I mean all out. This time I got everything perfect. Even put a TCI converter in it.
I tell ya, WOT pulls with a good stall will put a smile on your face every time. Only problem is now I need better traction. So after all that, I could do another one without the manuals. Everything is 8ft-lbs well not everything but you know what I mean.

yeah man they are not too bad.ive done a few 4l60e trannys now and is a great learning experience.One thing is dont cheap on the clutches and steels..and pay attention to the manual. I personally think its better to rebuild your own tranny and understand its workings that a way down the road if you start having issues you can usually have an idea of whgats going on.

It'll handle anything you throw at it...until it gets bored and quits
Torque is really sneaky about searching high and low for that week link.
But seriously, unless you're making 500+ horsepower/torque, on slicks, and doing WOT dumps all the time, I wouldn't worry about it. Given that it's set up right with complimentary parts.

I did it but you need some special tools. It isn't very complicated.

First and formost, snap ring pliars.
Spring compressors for the case and input shaft.
Sealing ring sizers for the input shaft and stator shaft.
Overrun and forward seal protectors
Bushing installers. Not the autozone kind. I got lucky on set of Ebay.
Slide hammer. Not necessary but makes life alittle easier.
Pump alignment band.
Alignment pins. I made some from old valve body bolts.
A shop press.
There are a bunch other special tools but if you're creative, you can do without them.

If you decide to do it yourself and get stuck on a certain part. I'll tell you what tricks I used.

That's what I mean't when I said input shaft, but yeah that. Also forgot about the reverse drum springs. I've removed the input drum and reverse springs by hand. But you will not get them on by hand if you install the transgo springs.

The factory service manual for your vehicle and/or ATSG manuals. Just search on Ebay for 4L60E. That would be the easiest.
