Default Trannsmission

So since i cant find a 4l80, i got my hands on a TH 400 out of a motor home, I will get a rebuild kit for it and give it a refresh. The question i have is what exactly will i need to make it work with the current flex plate? or do i need to get a different plate? i have read all over but nothing i read is giving me the confidence in what i will need for it. also engine is a 2005,l33(not an lm7) like the thread says. with a dished flex plate. anybody please feel free to give me some pointers on this. iam getting closer on putting the thing in... just minor set backs... like this. are kicking my ***. thanks

Default Flywheel spacer or new flex plate

Still have a question on the tranns, i got the 400 all dissassembled and starting to go back together,was wondering as to the spacer, hues has one that says its for 99-04 ls style engines, but mine is an 05 l33, can anyone let me know what to do here?? Thanks

If you search rock auto, look for a flexplate from a 2001 Silverado with the 6.0L. It comes with the spacer and bolts for around $54 + shipping.

Got tranns all together, will be running a 3k stall,i used the spacer that you drive into the flex plate,still have to elongate the holes a tad but other than that she should be good,on other notes,the BOV , Fuel psi regulator and fuel pump showed up, went with a walbro 255, will eventually run two, but not going to put in and be running a bunch of power right away. also got all intercooler piping in and should be on target to pull engine this upcoming weekend if all goes right.Also got fuel cell all fabbed up and installed,had to install in bed as to the truck being to low.will post some pics this week.

How hard is it to find 4x4 versions of the 4l80e in your area???

2x4 versions around here are scarce as hens teeth...I have converted 3 of the 4x's over for my projects over the years...

I hope to see some running pictures of this thing...

I have an '86 C-30 dually LQ4/4l80e I built back in '08...I'd like to turbo it soon...

It's easier to come across the 4x4 versions by far, still not super easy but I have ran across a few, but haven't needed one since I put a 400 in mine for now... I will try to put the video on here, my POS phone hasn't let me transfer anything lately.... Man I was like a kid in a candy store Sunday when it fired for the first time tho.

Really like the progress you are making bro. Is that turbo an S475? How much?
I almost went with a TH400 but I just know I am unwilling to compromise on over drive.
