Big Problem, Rear wheels locked up 90 GSX

[teknicalissue]

I read other threads about the rear wheels locking up, but my case is just a bit different..

I had changed out my tranny so there was no fluid in the tranny, and i think there might have been no fluid in the transfer case. I had to tow my car off some property so i called a buddy of mine with a truck and its towing claws.

Well i strap on the front wheels, and we get it ready , we began to drive off and approximately 5 minutes from driving the rear wheels locked up

So my friend put it in reverse and they spun fine, then turned around driving slowly back to where the car was originally and the wheels seemed to spin fine (although it was about 5 MPH)

Is this something i need to worry about? right now the wheels are not locked because you can move the car back and forward without any struggle from the rear wheels...

So you are saying you towed your awd car with the front wheels lifted and the rear wheels rolling on the ground? If you did.... You've done some damage With an awd vehicle you have to flat bed it or disconnect the rear end/driveshaft etc.

You probably broke the viscous coupling. May have even damaged the transfercase. At minimum you are looking for a new transmission. NEVER tow a awd vehicle with any wheels on the ground.

yea i just learned a life lesson..

ugh this sucks i JUST bought a new tranny....

it doesn't seem locked up anymore, but you guys are saying that something is 100% definitely screwed?

EDIT:

Is the viscous coupling in the tranny? where is that located exactly..

If it is.. would i be able to use the one in my old tranny????

You can replace it. But It might not be the only problem. Take a look in this thread.

ok that's good at least, i WONT have to buy another tranny...

after work im going to see the car, what and where would you suggest i look for? cracks? leaks?

 

[1badpurple]

Unless you seriously broke something I doubt that you would be able to tell without opening the trans. Its a almost positive assessment that you broke it.

 

[teknicalissue]

ok, what about the transfer case, how would i tell if that's damaged?

 

[1badpurple]

Fix the viscous coupling first. Check fluids and try and drive it and listen for odd noises. Or you can put it on jackstands all the way around and slowly let it engage in gear and listen for problems. MAKE SURE ALL WHEELS ARE OFF THE GROUND IF ON JACKSTANDS!!!!!!!!
