Hey, just want to do a pole.
Witch trans would you suggest?
4L80E/Quadzilla OR TH400 Terminator.
Cost is huge difference. Overdrive is very nice though.
My 427 4L60E.TOO MUCH HP
You can find these transmissions at WWW.transmissioncenter.net/4L80Ehtm
Thanks

 

Have you looked at Pro Built Transmissions

 

I say be ballsy and try to do a 4L80 swap! Everyone and their third cousin says they are going to do it but they figure out they havent the wallet for it!

 

If you are making serious power, than I would go with the 400T with gear vendors OD.

I ended up going with the FLP 4L60E, just because I didn't want to loose the OD, and didn't have the $ for the above. It's too early to let you know how it is gonna hold up. So far its down to a 10.6.

 

Give this guy a call. He builds race transmissions for a living. He can tell you what is the best way to go. His name is Richard Bewick 248 828/7048. He built a trans for me and I can't say enough good things about him. That is what he does for a living . He does alot of GN transmission.

 

You should think about a TH200/4R. Turbo Buick guys run those below the 10s if I'm not mistaken. And there isn't such an enormous rpm drop between 1 & 2 like in a 700R4.
