Re: 4l80e almost done trans go has a stick contoller so it will be full manual shifting 
and a lockup in overdrive. kind of like the th400 guys are doing - until a trans brake goes in :p. it weighs about 85-100 pounds more if I remember correctly. it uses 7 more horse power than a 4l60e . will get pictures out soon-

Re: 4l80e almost done a stock 4l80e will handle about as much if not more than any "built" 4l60e. a built 4l80e can be rated for 900-1200hp , so quite a bit more. it's basically a th400 with overdrive.

Re: 4l80e almost done Whats the advantage your trying to get out of this the only one I see is strength/durability the 4l80 is stronger but will most likely hurt your performance won't it.
I know this take a new 1/2 ton truck for a ride witch has 5.3 and 4L60E with 3.73 rear, than take a 3/4 ton with 6.0 and 4L80E 3.73 rear and you won't believe the difference.
The 1/2 ton will kill the 3/4 ton off the line,yes there is some weight difference here but the 6.0 has more hp and torque at earlier rpms.
My 6.0 is a bone off the line and I couldn't figure out why so here is what I found out it's all in the gearing of the transmission.
The 4L60E first gear is 3.06, the 4L80E first is 2.48 so you see the 4L60E has a much greater advantage coming out of the hole to start with.
This is why chevy put the 4l60e in the silverado ss with the 6.0 to make it quicker.

Re: 4l80e almost done the 4l80e is a 4 speed- it comes out of 3/4 and 1 ton trucks /vans. the main advantage that I'm looking for is the durability. same as why people are putting th-400 in there cars. you can get the 2.75 first gear set just like the th-400 in fact alot of th-400 parts fit on this trans

Re: 4l80e almost done recieved the TCS converter today- Derek does a great job-it's half ls1 and half 4l80e / still a 4400 stall so it should work as good as the pt 4400 that I use to have. the shift kit is almost done also =
