is the 4l80e really the be all end all trans? or does it just take longer to break? how long does a built one last with 6-700hp that gets driven hard daily? will it take years of abuse or months? are the clutches stronger than the 4l60e? as in have more clutch area per pack? i understand the parts are stronger but are the clutches bigger and less likely to slip?

 

Mine is stock except for the HD-2 shift kit. I have been beating on it for 2+ years now at track and on the street along with lots of daily driving. Im sure It's on borrowed time but I have another low mile 80E all ready for the day it gives up.

 

Are you already looking for your next trans?

 

your not thinking of taking that level 7 out are you?

 

the shifts feel a lot better honestly.

 

but are the clutch packs stronger than the 60e? as in less likely to slip when power is applied?

 

Yes the clutch packs have more surface.
It is basically a TH-400 with overdrive.I believe it shares some of the same parts also.It also has less gear ratio drop between ***** there for less torque is transferred into heat.

 

I had a completely stock one for almost 4 years. Put about 130 1/4 mile runs on it and it is my DD. Carry about 400-500 lbs of supplies and tools in the bed. It had 27k on it when I installed it. It now has a total of almost 150k on it. It started acting up a few days ago. Iam getting it rebuilt to stock specs, except for a shift kit and vacuum mod. The clutch surface area on the 80e is about 3 times the area of the 60e. My rwhp is about 600 for daily use and 700 at the track. A stock 80e is superior to a fully built 60e.

 

is the 4l80e really all that?

yes. it is completely bad ***.

i would expect a built 80 to last pretty much forever at 700rwhp.

 

My Rossler 4L80E gets more and more "comfortable" feeling the more boost/power I throw at it, they are quirky at times but once you work past that they are better in just about every way IMO. The shifts are great and I don't ever think twice about stabbing the throttle. I know its gonna hold. With all my 60/65's, I held my breath every time I made any WOT pulls...
