nbs gm w/sas running auto trac transfer case - Pirate4x4.Com : 4x4 and Off-Road Forum

1bigfnz · 08-08-2006, 09:04 PM

i have read several times that i can not run my auto trac transfer case with my sas. does anyone know why? any possible solutions? i thought about running a divorced 205 behind it.

Swap in a part time case. A 241 or a 208 (I'd go 241). What side is your diff on your front axle on? You can still put a divorced case behind the married one, either way, for a cheap doubler if that's what you are going for.

1bigfnz · 08-09-2006, 08:39 PM

my chunk is on the drivers side. ford front. so a 208 will bolt up to my motor or will i have to have an adapter? do you know why i can't run stock 246?

American · 08-09-2006, 09:37 PM

NO the 208 will not bolt up to your motor... no transfer case will.

Sure man, try running the 246. You'll change your mind real quick.

ha you said swap in a 241 or 208. that means swap it in.. how can i do that when your next reply is. no transfer case will bolt up to my motor. i'm not a rock crawler or do i play in alot of mud. i just want 4wd again so when i do need it i will have it and i have always picked on big lifted trucks with no front driveshaft i don't want to be like that.

Well what do you use it for then?

The no t-case will bolt up to your motor thing is because a transfer case bolts up to the transmission. Not the motor.

But I honestly can't answer the question about the t-case in full confidence. I have forgotten which ones are bolt in. But I ... THINK ... that the 241-c is a bolt in. 208 might be too.

black4x4 · 08-10-2006, 07:51 PM

get yourself a driverdrop 241 from a 88-98 chevy 1/2ton and it will bolt up the hardest part of it will be you need to get a vss plug from that year truck and splice it into you current t-case harness. i beleive it is the rear most plug on the t-case, but not sure pm darketernal he should now he done it in his truck.

I think the auto track won't shift right with out the acturator and sensors from the stock front end.
Most people on a SAS go with the NP241 Pass. drop transfer case which is what American was saying cause they use a chevy front end.. Now with that said I also think a Lever shift transfer case 99 and up should work just fine. But not sure.

American · 08-11-2006, 04:40 PM

driver's drop 241-c is the ideal swap in IMHO. Just source it from a 88-98 body style GM. Maybe 99+

bggrnchvy · 08-11-2006, 04:48 PM

The newer trucks use the 26x cases, from what I understand the casing is slightly larger and magnesium instead of aluminum. Id try to find one of those to swap in if it were me.

1bigfnz · 08-12-2006, 01:06 AM

ya american i understand you were trying to be a smart elic but it don't work bc i look over small comments like that. the funny thing is you knew what i was talking about but its cool. well i can get my hands on a 241 out of an 88-98 chevy but its either that or run a divorced 205 behind mine.
bo185- yes i was thinking the same thing about it not acting right without the the stock front end in my truck. too many sensors to be messing with.
