I am pretty sure the sun shell went out on my 1998 Silverado. How hard is it to replace the sun shell on these things? How far will I have to dig into it to get the sun shell out and replace it?

Might as well rebuild it as long as it is apart the overdrive on the 4L60e is also a weak area. While I am not saying you couldn't rebuild it,you would need a ATSG manual and a few specialty tools.
You might better pull the tranny out yourself and find a GOOD tranny shop to do the bench overhaul on it. You should be able to find somebody to do it for 300.00 labor plus parts or so.
Don't forget to flush the tranny cooler before it goes back together.

Hey thanks for the reply. I have already pulled the transmission but I havent dug into it yet. I live in Fort Worth, and the 3 shops I called wanted $1200 for a bench job! I was looking at this transmission DVD to help me along:
http://boxwrench.3dcartstores.com/GM-4L60E-Transmi...
I really didnt want to dig into it but Im kind of strapped for cash right now. If I can replace the sun shell and get down the road for a few more months before I get a rebuild, that would be great. I was hoping I could replace it without taking too much apart. Any idea on what it takes to replace one?

Here is a 11 page thread with pictures at another forum. I did not go through all the pages but he shows tearing a tranny apart.

I found some pics from a guy over at the blazer forum pulling his sun shell. It looks like I wont have to dig too deep to replace it.
Pump.
Pump removed. Input and reverse clutch assembles removed. 2/4 band removed.
Output shaft removed, inpust gears are removed. Looking at the sun shell.
Sun shell removed.
Is it that easy or am I missing something here? Will I need to mess with the valve body for these parts to come out? Will I need any special tools?

Don't know if you read that thread much but on page four he posted the diagrams from a ATSG manual. They are real helpful. I picked mine up at NAPA for about 20.00

PS. A camera will be your friend!  Take lots of pics when it is coming apart for reference if needed when going back together.

Yes, I have been reading and it is exactly what I needed! He says the "correct" way to remove the 2/4 band is to remove the valve body. There is a pin or anchor in there that holds it in. That kinda sucks, I was hoping I wouldnt have to remove that... He also said "I gone in and just replaced the sun shell with minimum seals on a couple of trucks and they are still going strong today" which is encouraging. Good tip about the camera. I have a digital camera that I probably wouldnt have used had you not reminded me. I'll try to post some pics if things go well. I am about to clean off my bench and get to work.
Can anyone confirm I need to remove the valve body to get the 2/4 band out? EDIT: Never mind. I see that I do need to remove the valve body to remove the pin.

Also watch the length of the bolts on the valve body. If you get one too long in the wrong spot it will hit the sunshell. Don't ask me how I know. 
Also a small torgue wrench that will read inch/pounds is recommended for the valve body.
You will need new gaskets for the valve body and probably a new separator plate as they tend to get beat out where the balls seat.
If possible I would get The Beast sunshell.

Buy an inch pound torque wrench from Harbor Freight to properly torque your valve body bolts back down. Also you will need to be carefull to get all of the check balls in the proper location. You may need petroleum jelly to hold them in place during assembly. Don't use any other type of grease unless it is made just for this. A high quality pair of snapring pliers is usefull to remove and replace the snap ring that holds the output shaft into the trans.
And make sure you buy a heavy duty sunshell for the replacement. The sunshell failure is, in my opinion, one of the top three causes of 700R4 or 4L60E trans failure. "The Beast" is one of the better ones and probably the best known. (About 60 bucks).
PM me if you have difficulty. I am doing four of these transmissions in the next three days.

Really, really want another ElCamino. |

Yep. Broken sun shell. It wasnt too much trouble to remove it. I set each part aside leaving all the bolts loose in their original holes. Everything else looked like it was in good condition. It was a good strong transmission before this happend.
Thanks for the petroleum jelly advice. That will come in handy when I put it back together. I guess now all I need to do is clean the hell out of everything, buy "The Beast" sun shell and a seal kit?

Hey Micaletti, how did your replacement of the sun shell go? I'm in the same situation you are and was planning on doing it myself. Do you have any tips you can offer?
