What is the difference between a 4L80E and a 6L80E?
“Stock versus stock, the 4L80E and 6L80E are very similar in terms of strength,” explains Kyle House of Circle D. “The main difference is that the 6L80E has much more versatile gear ratios. With a ridiculously low 4.03:1 First gear, it’s a stump puller.
What is better a 6 speed or 9 speed transmission?
The 9 speed is way quicker off the line with it’s super short 1st gear. On the highway the older 6 speed has much more jarring RPM jumps when you need some acceleration where the 9 speed is much smoother and doesn’t need high RPM as often to get the job done.
Is 6L80E a good transmission?

What is better a 6 speed or 10 speed transmission?
Compared with the 6-speed, the 10-speed delivers improved overall performance, with enhanced acceleration at the low and mid ranges of the power band.
Which is better 4L80E or 6L80E?
The 4L80E is more proven because it has been around much longer and more parts are available for it, but the 6L80E has come a long way and they can handle tons of power with a few basic upgrades.”
