Tried to get the car out this past weekend but it went downhill fast.
Here are I believe are the pertinent facts:
1. Small blk with Passon Alum 4 speed 6? years old, , 2000 trouble free miles, has sure grip, OEM tapered axles. 2. Car has seen no miles in 4 years 3. When car sits on jack stands, rear wheels and DS turn easy by hand when in neutral both ways, engine off. 4. Engine starts fine, pushing clutch in tranny goes into any gear fine. 5. When letting clutch out when in 1st gear on the jack stands, unless revs are brought up to say 2500rpm engine dies, and wheels still turn very hard/slow. 6. Pushing clutch in with trans still in gear and with wheels still turning, causes wheels to immediately to lock up. 7. Above is the same in 2nd but much harder to get wheels to turn, reverse the same, can't get wheels to turn without killing motor in 3rd or 4th. 8. I can get trans side cover shift levers into all normal? positions from below
Nothing indicates to me clutch/pressure is stuck. Not sure if 8.75 could lock itself up. Everything goes south with trans in gear?
I'm at a loss, and am trying to eliminate as much as possible before yanking trans.
I have called Jamie and we are scratching our heads.
Any ideas?

I would burn the clutch up before getting it out of the driveway. I put it on the stands to assist in troubleshooting, and see what was locking up.

The DS turns fine both ways in N so the 8&3/4 is not the culprit. #6 makes me think it is a clutch issue but that's speculation on my part since I am not a clutch/stick guy (904's forever). Here's a BTT & holler how it goes

It is a 742 Alum case.
I'd love to have that as it'd certainly reduce alot of unsprung weight in the stock car. I'd maybe take off the clutch cover & side cover again & see if anything abnormal is apparent & maybe haveing a helper work the pedal & turn the rear wheels by hand & you underneath would make something show up

If you really think that the 8 3/4 is the issue, wouldn't pulling the driveshaft either confirm or deny?

Pulling the DS is not that big of deal at this point, and it will definitely rule out the rear end, and I have few other options. Thanks

Not stupid, and yes, nor seem to be bound up in any way, and wheels turn freely in the air. I'm hoping it is something stupid, but unfortunately I will have to come here and tell you guys, don't know which is worse?

Seen this happen to some cars that sit for awhile, everything seems fine when the vehicle is jack up, but once the wheels are on the ground and a resistance load is applied to the rear end the car goes no where, or it takes some serious RPM's to move it,...9 out of 10 times it's the rear end, drop the driveshaft, all 4 wheels on the ground you should be able to move the car forward and rearward by hand, if you can't, then it's the rear,...sure you can pull the chuck/axles, but what I've found that works best is to just pull the shaft, and slowly tow the car in any fashion as long as the rear wheels are on the ground, usually frees up the rear axle without any harm, last parts car I had recently had this issue... mike

First I'm working alone at this point, so my observations are limited.
I dropped the DS, seemed a normal amount of tranny fluid ran out, so its not dry. Started car without DS, put in 1st, let clutch out, no bog, no hesitation, had no way to verify trans output rotation, was worried about sticking a spare unsecured yoke and it spitting out, and I would have a hard time viewing it anyway by myself. I can get helper tomorrow if anyone thinks seeing it rotate is needed at this point.
While DS is out, rear end yoke turns nice both ways, feels to be normal, has some play, more then what I would like, but it Is what i have felt in past on other 8.75. Reinstalled DS and big bog in 1st gear and hardly can get wheels to turn in the air.
So unless the 833 will only bind up with a load or with a yoke, and I need 833 experts to advise on this possibility, it would then point to something in the rear. The 8.75 was built by a well known local shop that assembled my new R&P, rebuilt the SG, with all new parts in the Alum carrier. Could an adjuster nut backed out, and ring shifts and locks under load, or a SG bolt back out or ring bolt? I know that's all guessing and pulling the rear end is only way to find out for sure, just want to check off 833 first.
Thanks guys.
