4l80e swap on a 98 z28 camaro
there has been 3 4l60e's put in it already and they have all gotten 40 miles or less on them and then have broke... need a 4l80e as it will hold up to the horsepower this camaro is putting out.
which means i need to find everything to do the swap.....

Personally I'd go with a larger stall though even though I don't know your mods.

The stock PCM will work but you will have to have a segment swap done; meaning having the 4L80 info integrated to your current tune. The problem with this is that there's no flash for a 4L80 equipped f-body. It can be done but IDK what all is involved.
Look up Cablebandit on here too; he's done the swap and is from Ga. as well. Where are you in Ga.?

can i drive with these stalls on the high way with 390 gear?
and which yank converter should i use with the 200 shot?
i found a yank converter from a 99 c5 corvette with a 2002 4l80e, ss4000. would this work for my application?
Yank, Circle D, possibly FTI (not sure if they do the 80e)
With that much hp, it may or may not. A good rebuilt one will hold up fine.
I *think* I can get a 4L80E to run on a 4L60E tune. I need to test it still though.
Million ways to go fast...
You will not be able to do the tranny segment swap with the 98 pcm. You could stand to benefit a great deal by upgrading the pcm to a 99+up and get to take advantage of EFI Live's Custom Operating System #5 that would allow you to run MBT N/A and at the flip of a switch while driving pull timing and add fuel instantly for the N20.

[] thanks for all the help guys. my computer tuner swears he can make my stock 98 computer work with the 4l80e. anybody know for absolutely positivley sure whether it will or wont work?! not that i dont trust u guys that say it wont or will, i just need to know for sure if anyone has tried it.my sponsor wants me to run a vigalanti stall with triple clutches.he is also the guy that says his tuner told him he could make the stock computer work in a 98 pcm.
Too many people are saying yes and no to using a stock computer. has anyone tried using the pcm or know anyone they can ask that has done it.
Jim at "Speed Tweekerz" said his tuner said it would work. He is usually very good with ls1 knowledge. he has helped me so much, and has not guided me wrong yet.very good on customer service and fast shipment and prices.
Car is being trailered from here to his shop in Missouri. to be sprayed for the first time on the dyno to be tuned, hoping for decent numbers.
you can check out his website at www.speedtweekerz.com he is full of knowledge and even some people say "ls1 gear headed guru". but dont tell him i said that. lol :-D
is a 3600 stall gonna be ok for everyday driving?
Aggravated, turbo 400 is still lingering in my head, but i know everyday driving will be less obtainable.
come on guys ... keep it coming... help me out... please!
you can listen and see the car at this link!
the tag now says "HEREHRC" for those pesky mustangs..
