[xland61]

Thanks for all the help with the 5R55E transmission found one out of a 2000 explore 143k truck was totaled hit in the rear so that brings me to my next question anyone tell me how much trouble is it to drop the 2000 Sohc in place of the 1997Sohc both are 4.0 V6. and if so what do i need to change to make it work i can buy motor and trans for 300 buck what a deal. Thanks for your help in advance.:exp:

1997 vs 2000 SOHC V6

Your 1997 has a variable intake system (VIS) and the 2000 doesn't so some of the engine wiring harness and the vacuum harness will be different. The 2000 has an integrated MAF/IAT sensor and I think the 1997 has the IAT sensor separate from the MAF sensor. I can't remember for sure but I think the camshaft position sensor is different.

The simplest thing would be to reuse the 1997 engine wiring harness on the 2000 and to swap the MAF, IAT and CMP sensors and the main intake tube.

I would swap the upper intake back in also. It might not fit the 2000 EGR though...

upper intake manifold

I agree. Technically, the VIS seems like a performance enhancement although practically I doubt there is much of a measurable difference. I doubt that the EGR tube will be a problem.

So you guys are saying that it will interchange but do you know if the 97 intake will bolt back in place of the 2000 intake? srry but dont want to be stuck with a pig in the poke lol

long block will work

The 2000 long block will definitely work. It's just a matter of how much you need to remove from the 1997 to bolt on to the 2000 long block.
