Is it possible to convert the car transmission to 4x4 by swapping out the tailhousing?

You will have to change the tail housing to the 4x4 case adapter for sure. (~$98 new) ...and replace the output shaft on the transmission. That requires disassembling the transmission by a transmission shop. Usually costs about $250 plus the new 4x4 shaft.

At that point, you could ship me your ECU and TCU/valve body out of the trans for reprogramming.

Not sure if it will help anyone but there is a sticker with the different codes on the vehicle that you can use to find out a little more information.

For example the code for the 6l80e transmission is MYC
The motor code is also listed on this sticker in the case of the one show here LC9

I found it helpful when looking on ebay as many of the dismantlers post a pic of the sticker so I could at least know what motor/ trans and then just needed to figure out if it was 4x4 or not.

After all that, we need to see what the pedal response is like. It may still throw a code. We will have to see. Anyone have more info on this?

I think I found the GM mating connector at Mouser, 15326833
You should be able to calibrate the pedal to the ECU? All you need to do is let the ECU know where closed throttle and open throttle is and Bob's your Aunty?

My roommate in college did an 8100 swap in an 80s pickup truck and I remember it didn't run with the first pedal and pedal module combination. There is some split and not all were compatabile though they had the same part number on it. I do remember measuring 3 pots on it that all worked.

That's the build sheet sticker showing all the "options" added to that truck at the factory. Eg z71 is one most folk know.

Motor arrived a few days ago

LC9 5.3L w 4x4 6L80e purchased as a lift out package with 40k miles came with the harness and ecu as well but I removed them already to send off to speartech to turn into a stand alone harness.

Nick,

It looks like you reversed the intake manifold on the one in the 90 is this required or just something you did to get the throttle body out of the way?

From what I have read it is really really easy to do and the only issue some people run into is with the oil pressure sender. Did you have to modify / change the oil pressure sender?

I hope I can pull it off, I spent and hour on the phone with Nick before I was 100% sure I was going to give it a go and he seems like a nice guy that is willing to make it happen. Not something I could do on my own at this point but with Nicks help it sounds like it will happen. We will see if I stepped up or stepped in it

For people asking about the cost of the lift out motor package it was right about 4K shipped. there were others for less that had higher miles and I am sure if I waited around I could have found one for less but I really want to have my 90 on the road for the Rally in Sept so I have to get the process started.

.
you can shave it off, and get someone to tig weld it closed as long as you don't want the sender.

$4k shipped doesn't seem bad. It would probably cost you that much to gain the HP (not to mention fuel efficiency) from a Rover V8. Looking forward to hearing/seeing more of your project!

The intake was reversed for a couple reasons. The hood won't close and hits the throttle body. Having the throttle body in the back gets it out of the hot air and facilitates the air filter fitment.

I didn't have to modify the sender. I test fitted both the truck intake and the Camaro intake. Neither interfered with the sender.

Another part sourced

For this swap you need to buy the hi/ lo - CDL mounting plate from an automatic 1994 - 1998 Discovery series I. this is where your CDL attaches and the plate for the shifter. I suppose if you have a 1997 with an automatic you might not need this part?

They are pretty pricey if you buy one new online ~ $120 so I opted to go to the local pull and pay and got one for $9.

Here is a picture for future reference (lifted from Ashcroft where they sell for 60 GBP).

Question for you Nick. Are the 4 holes in your Adapter in the same location as the automatic Discovery transmission? From looking at both it seems so but just wondering if you kept the exact same location.
