2011年7月27日 · A 4L60E would be behind a 4.8L and 5.3L. 4L80E was only used in 3/4 ton and up trucks. Plus the 4L80E is a big, heavy transmission. Strike_Zero HalfDork

I had a 99 reg cab 4.8L 3.42 rear for about 5 months. GM bought it back (vibration problems). Now have a 2000 ext cab 5.3L 3.42 rear about 3 weeks. The 4.8L in the reg cab was fine, not as much low end power, but once you got the RPM's up a little it had plenty of get up and go.
