OK as stated can will a AWD drive with the t/c removed? I know this sounds stupid and I usualy would not ask, but the wife's BMW has taken a transmission crap:notgood: and I need another driving car.

I have a gst spyder with a AUTO capmission:notgood: that is blown. I want to do a awd swap but have yet to find a doner car for the right pice within a reasonable distance. I want to do the manual swap but want to know if i get an AWD transmission will it drive with out the t/case. There is not an AWD rear end in this car as of yet.
 
I need a viscous elimiator? I dont want to put the t-case on unless I have to. For reason like the transmission leaking fluid (I dont think this is an issue I looked at my 1gs and looks like they wount leak) or not engaging (this would be my main concern). This is what I really need to know.
 
Well, unless you want the viscous burned up, you need to do like one of the above that was mentioned. So to answer the question, unless you do one of the above....no, you can't.
 
I had a friend do it in his 91 for quite some time ( about a year) that was before I got a dsm. We installed the T/C and axles and everything was fine. I dont belive that he had anything done to the viscous.
 
The viscous will be more of a problem if you remove one of the front axles. It's not meant to deliver all the force continuously to the rear or to have the rear spin at a different rate than the front. If the pin is let to spin freely, then viscous should be fine.
 
The viscous delivers the power equally in our cars though, correct? From previous experience, I broke both rear axles at the drag strip and blew my center diff in my transmission. That was a bad day for me. Oh well shep stage 4 trans and welded center diff, and new rear axles solved my issues.
 
Okay lets try this again seems no one has quite hit the point. Will the car drive with the t-case NOT atached to the vehicle? If it is removed from the car I do not need a viscous eliminator. The viscous is in the t-case, correct?
 
The vc is in the tranny, not in the t-case and you will need a vc eliminator atleast.

If you plan to run an AWD transmission in FWD mode, you'll need either a welded center diff or a VCE. Period.
 
it will move as i just did it. it will most likely mess up the VC over time (may take minutes to days depending on how the car is driven and the condition of the VC) ,and most importantly it will not have full power to the front wheels. it feels like a clutch slippage and the car hates to go uphills (really starts to slip then).
so, short anwer, yes it will drive but it will likely mess up VC and will not be safe to drive as it feels like it has a bad clutch so NO don't do it

wow, imagine my long answers :)
 
Yes the car will move, but the viscous will be 'slipping' when you accelerate. The viscous is not hard to deal with, it's right under the cover on the tranny. Pull the cover, a snap-ring, and the viscous. Either weld the viscous or get a VCE. put the 3 items back on (remember to put RTV sealant on the cover, obviously). Done.

Why would being AWD make your tranny leak? If you mean the t-case leaking because of no driveshaft, yes the fluid will run right out, but it's not the transmission fluid that will leak since the tranny & t-case have the oil separate from each other. And what exactly wont engage? All the t-case is basically is two gears, the viscous AND center diff AND front diff are in the transmission.

Okay lets try this again seems no one has quite hit the point. Will the car drive with the t-case NOT atached to the vehicle?

I think we've all already "hit the point" of "you will fry the viscous if you do this".
 
Thanks for the help. I did not know the viscous was in the trasmission. Also was not sure if the bolts for the t/case went trough the the transmission case hence the reason I was asking if it would leak. I knew if I remove the drive shaft the t-case would leak.

Sorry for all the confusion. I just wanted to have a crystal clear understanding of what was needed.
