So I am planning on swapping to a 4L80e and a guy is selling a built one, but it has a stand alone ECM and wiring. So I am wondering if this is a good way to go or not. Also if I did go this route would the transmission Temp Gauge work or would I have to do something to get it to work. Any info would be great. Thanks!

I was looking for a 4l80e and a scrap yard is offering me one for 650. Is this a good price? Located in Saskatchewan must also be taken into consideration.

Was looking at eventually getting a beefier tranny because blowing a 4l60e/year isnt reasonable. Where would i find a decent transmission? What do you know about salvaging parts from wrecks: http://www.sgi.sk.ca/lcgi/salvage_bid_site/comp_details.cgi?stock_num=R132932&store=Regina

I am putting a built 4l80e in my 2003 Silverado SS, it has a cammed LQ9 and STS turbo kit, which I plan on running around 12 PSI. Just wondering what is the best brand and speed of torque Converter to get with this set up? I was thinking of either a 3200 or 3500 for stall speeds; I never haul anything with it and don't drive it very much. Also what is the best aftermarket cooler to run with the 4l80e? thanks Also not to get off topic but does anyone of any input on injector I should run; Brand and size.... Also is a FAST RT intake 102MM worth the money? Thanks for any input
