I found a garret gt2256v from a mercedes 300d in the trash today and the only thing wrong with it was the exhaust impeller, I've replaced it and it seems to spin just wonderfully now, can I put it on a 6.0?
I'm not trying to make a whole lot of power, just more than 350

I know this is an older thread but I'd like to know the opposite:
What do I need to run a billet 10-vane rotor in an '07 non-ISS 4L60E trans, 7KCD, if it matters? It's for an '04 5.3L vehicle, but the core I'm building is a 7KCD (if it matters.) There was no ISS connector that would go into the opening above the pump (with trans upside-down) when I removed the pan; pump's not out yet. Can the rotor just be put into a 13-vane slide using a 10-vane guide? Do I need to buy a 10-vane slide? I also bought the TransGo 700-PKH ring kit...

leave the slide alone
swap rotors to your hearts' desire
a factory 10v rotor is perfectly fine...no need for billet
no need for billet any count rotor

Thanks guys. I already own a shiny new 10-vane billet rotor. Some racers swear by the 10, it has less spots to fracture at, including install mishaps & "over-tunes." I'm sure we've all seen tons of what can go wrong in Precision Transmissions' 4l60e teardowns on YT. I'm disabled and can't do the transmission R&R, just the rebuild. I haven't rebuilt a trans in over 20 years, I used to do 200-4R's from GN's behind Callies stroker SBC's, mostly Art Carr trans stuff and Lingenfelter SuperRam engine stuff, but I have some help online on this one from a Transmission Brotherhood member. Actually he's spoken highly of you guys. I'm trying to prevent parts breakage in a 5300lb. (w/driver) creampuff with just 3.42's & G80... I'm building the vehicle from the transmission outward...
While we're on the trans, can I get your opinions on 3-4's? Would you rather go with:

If any of you start Blue-Printing these Pumps regularly...
You will also find that the OEM/ GM Rotors and Slides are better made in terms of dimension tolerances...
compared to Aftermarket and Billet parts.
Years ago when the THM200-4R and THM700-R4 were still very popular, the Aftermarket Pump parts were mostly complete junk!
