I've used the 4L60E on a number of LS swaps. My 98 Wrangler LS6/4L60E combo has almost 14 years under it's belt with zero issues. Stock LS6/4L60E.
My 67 Nova project 427 cube LS2 (500 rwhp) had a "built" 4L60E from Finish Line Transmissions. 2800 stall billet converter from Yank. Worked great and I sold it a number of years ago but talked to the owner a month or two ago and it's still going strong.
My current 80 Fbody project has a locally built L92/4L60E/2800 stall Yank converter. I don't think it will be a problem. Run a big trans cooler. Don't let the tuner take out all the torque management out of the tune. My .02 if you aren't going to put monster power to the 4L60E and it's built right you will be fine.
