NFPGASMASK- One of the unknowns of the swap is the longevity of the stock 4L30E transmission. Because I am wanting to keep awd and TOD I am going to see how it does with a brand new 4L30E. This way if it blows in 2,000 miles I will tell everyone that the transmission wont hold the power at all. Also if you are hammering it around every turn and from stoplight to stoplight the V8 will destroy the transmission far faster than the stock V6.

DutchKiwi- I had not looked into the PCM that you had mentioned but will be doing do once I click post. The 4.6 came with the GM PCM and we will be wiring that into the stock Isuzu PCM so we can get TOD and the power reduction during shift to work with the NorthStar.

my next hurdle will be finding out of the oil pan clears and of if not finding an oil pan that will.
Since a GM 4L60E is the automatic for C4 Corvettes, I googled "4L60E vx 4L30E". That's because the vette transmission handles the appropriate amount of torque and HP.

Interestingly enough, I found this quote from "Isuzu Jerry Lemond" on the topic...

YES IT CAN AND WILL FOR THE MOST PART BOLT UP, BU T HEN THE FUN BEGINS, WITH THE WIRING , AN EASIER SWAP IS TO USE A 700 R4 FROM A CHEVY S 10 2.8 ENG , IT BOLTS RIGHT ON, AND CAN BE MODIFIED TO EASILY HOLD 350 HP , AND THE EASIEST PART THE CONVERTOR WILL BOLT RIGHT TO YOUR STOCK FLYWHEEL, AND THE ENG BOLTS RIGHT UP. TO THE TRANS CASE , A LITTLE WIRING FOR THE CONVERTOR CONTROL LOCKUP AND YOU WILL HAVE TO FAB UP A BRACKET TO OPERATE THE THE KICK DOWN CABLE SO THAT YOU CAN ADJUST THE UP SHIFT POINTS OF THE TRANS , ,
A 4L60 WILL ALL SO WORK AS LONG AS IT IS FOR THE 2.8 ENG THE 4L60 E IS A DIFF ANIMAL ALTOGETHER AS FAR AS CONTROL GOES ,
THE 700R4 AS GM ORIGINALLY BUILT IT WAS JUST LIKE THE TURBO 350 A REAL [PIECE OF CRAP , UN TILL THE AFTERMARKET GOT HOLD OF IT AND MADE IT WORK LIKE GM SHOULD HAVE OR COULD HAVE IN THE VERY BEGINING , AND NOW BOTH TRANS ARE AS GOOD AS THEY COME , THE 700/4L60 HAS A 3.06 FIRST GEAR AND A 30% OVERDRIVE , ABOUT AS GOOD AS IT GETS, ONE OF THE GUYS ON THIS BOARD ABOTU 5 YEARS AGO PUT THIS SAME SETUP IN HIS RODEO BUT USED A DANA TRANS FER CASE AND IT WAS VERY CLOSE TO THE TORSION BARS, BUT I THINK HE CORRECTED THAT WITH A SAS, BANSIL REMEMBER ANDRES OLD RODEO, WHEN WE HAD ALL THE TRANNY PARTS LAID OUT ON THE TABLE THERE AT URE MAKING ALL SORT S OF MEASUREMENTS AND IT ALL CAME TOGETHER
