Is the Seville still a good car ro get the 4T60-E out of?
I was told that that transmission with the 3.33 gearing it has was good for the 4.9 but
was wondering if it`s good for a 3.4
I will be using this to control it.

Yes, the gearing is good.

Why not just use a 4T60?

Well, I don`t know about other parts of the country but down here the 4T60-E is a lot more plentiful than the 4T60 plus my TCC
on my car doesn`t work and if it`s something in the computer I kind of like having all of the adjustments on the transmission right
from that box.

I ran the 4t60 with a 3.4 pushrod, It did 100 mph with no effort @ just above 2K rpm. It had the 3.33 gearing.
The only difference is the electronics. Look at my 88 Formula build, has all the references in for a trans swap like this except the electronics.

The 4T60E uses a slightly shorter passenger side axle than the non-E.
