How to make RWD car AWD?

I am trying to add in a transfer case to be Grand Marshal to make it AWD. I got the slot under the transmission category, and installed but the problem is that it creates a massive power loss on the car. On the ground, the car will only go around 1 mph. Don't know what I did wrong here. Here is what I put in the transmission JBeam:

},
"fullsize_transfer_case_AWD": {
"information":{
"authors":"BeamNG",
"name":"Viscous AWD Transfer Case",
"value":1200,
},
"slotType" : "fullsize_transfer_case",
"powertrain" : [
["type", "name", "inputName", "inputIndex"],
["splitShaft", "transfercase", "gearbox", 1, {"splitType":"viscous", "primaryOutputID":2, "viscousCoef":10, "viscousTorque":500, "friction":5, "uiName":"Viscous Torque Splitter","defaultVirtualInertia":0.1}],
],
},

 

You need to add a diff to the "front suspension" jbeam, you need to add a transfer case, and you need to add a splitshaft, and get all that working correctly in the "powertrain" code....send me the front suspension .jbeam and the transmission .jbeam files and Ill do it for ya

 

There you go. Thank you so much! I'm just now getting into the wonderful world of modding Beamng.

 

please send the rear suspension file as well thanks

(btw im at work so i will get everything together here as best I can, post it on here, and if its breaking the game I will sort it out when I get home ((after I drive on Italy for the first time lol)))

 

There you are.

 

thanks....now that work is picking up (just had about 5 cars come in and I need to get busy on quotes) i will most likely just handle this at home altogether...but I will get it done for ya no problem will require a bit of trial and error, this is the only car I never attempted a AWD conversion for. (are you looking for AWD or 4wd btw?)

 

AWD, thanks. I appreciate you doing this for me!

 

no prob. I currently have perfectly working (newer) Pessima AWD, the Legran is either 4wd hi/lo or AWD, and some other shit i have done. Its like the one thing I know how to do and make work perfectly lol

 

I was quite surprised when I saw that there weren't many AWD mods out there.
