Thread: 4t80E trans swap

My only problem is time and I'm missing the diagrams for the pinouts of these trans.
I need a quick solution. I have access to a super cheap 4t80E from an Aurora V8

I wonder if I could use the Aurora ECU and hook it up to power and essential sensors so it sees engine RPM and speed sensor signal and thinks it's running the 3.8 engine and disable the error codes.

Ok, I had a long talk with Dave at TEP and he had a lot of great info for me.
I will let him fill in the details of what he said to me.
But overall, the transmission swap seems very doable for my rear engine set up.

I think we're going for it.

I have experience with electronic switching and with Dave filling in the details I think we can do something good.
His main concern was the 2-3 shift but he was working with a very high miles trans. With some luck I can find a trans with a better shift.
If not we'll have wasted time but it's worth a shot.

In the meantime I may get good deals on the parts I need for a decent 4t65 build that can be used up front if the 4t80 trans swap works out.

I hear James turbocharged400 has experience with these as well maybe we can collaborate also !
