What is the best converter for a 4L80E? Is anyone running the converter from a 4WD truck? I am considering using the stock converter out of my 4wd doner truck, for now just to get the thing driveable ( and save a little cash right now). But I am not sure if that is going to cause any issues, and I also want to know what is reccomended when I do buy a new one thanks.
I went with a yank ss convertor for mine with a 3400 stall. Its only 9.5" versus the stock 13", but you need to get a ls1 flexplate too. I bought both just before christmas for 800 shipped. Great build your doing by the way.
I am running the factory converter that was in the G30 van that I pulled the tranny from. I just drilled and tapped two 1/8NPT holes 180* from each other in the lapweld, and flushed it REAL good. Then put in flush plugs with loctite. Did the TH350 converter in my truck the same way.
I was thinking the stock one would be okay for a while, until I do a head and cam swap. The converter came out of my truck, which had a trans flush about 1300 miles before it got wrecked. I dumped a little fluid out of it and it still looks and smells brand new.
