4L80E conversion update / pictures
Its been a while since my last post....I have been real busy..now back to the conversion. Updated the drive shaft / RPM bearing rebuild. Also used a custom designed output shaft for the C5 and the 4L80E. Rebuilt the trans with a late model case..better oiling and upgraded internals..
Car needed to be cut..few pics of the welded tunnel..turned out real nice!

Looks good Tom, surprised you stuck with the rubber couplers though. I have been thinking about this on my own car too, thanks for the pics.

the kit was originally made by Yank. I made some changes. Output shaft redesign, upgraded the TT shaft and rebuilt all the internals on the drive shaft assembly. I made a custom bracket on the bellhousing to mount the shift cable. I also rebuilt the trans with a few different upgrades and late model case.
It looks like it was simple to cut the car.....its not brain surgery but definatley alot off work figuring where things need to run. I took alot of time to design and fabricate the new tunnel section so that seats and console and all brake lines and wire harness clear....not a beginner DIY job....also need to have good welding skills...all welds were just spot by spot to avoid warping..
I am happy with how things are coming

Nice work Tom. Looking at the pic above its hard to tell how you adapted (or made new?) the rear cooling adaptor to AN for the tranny. Is this something that came with the tranny? I ask because I welded a -6AN fitting onto a modified stock rear fitting. It made the fitting a little long so its real close to the tranny tunnel by the time I put a 90 degree hose fitting on mine. If your fitting is the correct type that goes all the way into the center support but does a 90 right out of the tranny that is an adaptor I would sure be interested in 
I posted a couple pics below so you could see my adaptor. Please shoot me a PM if you can help...
Thanks
Bill

Take the stock fitting that screws into the rear boss cut the "quick release end just behind the oring inside the fitting...then drill and tap the inside...I believe I used 1/8" pipe. Then I used a earls 90 degree with a 1/8" male. I also drilled out the ID on the fitting to increase flow...dont go to much or you will weaken the fitting. I have done this on many fitting...works great. You wont get q closer tighter fitting...yours is a goos setup also...just not as tight..
Hope this helps
