How much HP can a stock 6L80 handle?
They feature custom nitrided steels to prevent warping, and more durable clutch linings that are more resistant to heat. With these modifications, a 6L80E can handle 500 to 600 rear-wheel horsepower in the typical street/strip application, although we have had customers push them all to the way to 1,000 hp.”
Is the Allison 4L85E a good transaxle?
The 4L85Es can withstand a lot of power and are overall a good trans proven through many years. If I remember correctly about torque managment. TM has little to do with pulling power, mostly for the transmission shifting and smoothness.
Is the Allison 8.1L a good long life engine?
In defense of the 8.1L, it is a decent long life engine that gave reasonable pulling power for Suburbans and pickups in the gasser class. Mine had the famous CSK and oil consumption even though it was pampered from the beginning. After spending over 100K miles in the seat of my 8.1L, I think the performance should/could have been a lot better.
Which is better a trans or an Allison?
Actually the 4L85 should put more power to the ground as its has less loss compared to the allison. As far as I know both trans use torque management the same. For what its worth I have a Yukon XL and love how it pulls. Actually the 4L85 should put more power to the ground as its has less loss compared to the allison. Click to expand…
Can you tell the difference between A 2500HD and an ally 4×4?
I had a 2500HD 4×4 w/ 8100 & Ally for a few years and have owned a 2500 4×4 Sub w/ 8100 & 4L85e for over a decade. I eventually had the ecm in the truck tuned and had torque management removed, and it was definitely noticeble on the bottom end (couldn’t tell a difference in mpg).
