I have had this huge problem with my sunfire (2.4 5spd) for a couple of months now but I havent had to much time to look at it and fix it. now I really want to fix it and I can't find the problem on the external side of the engine.
first it starts and runs greats, as I let off the clutch it starts to grab but as soon as any torque is put to the car it slips and grinds and the whole engine and tranny shakes and will not move much but I can slowly move it when needed. I put it on the lift at my shop and put the wheels a foot off the ground and put it in gear and it seems to grab just find off the ground. the tranny had some whine to it for a while and about 2 days before it started this problem it would start to slowly drift to the left then pop back into place and go strait
I really don't know to much about the transmission but I believe it is the problem. the car and clutch has 147,000 miles and hasn't seen to much slip until about 2 months before it quite on me, and even then it was very minor. what do you guys think?? clutch and pressure plate?? I am out of ideas for right now. any help would be awsome.

I'm thinking its the clutch and plate.
I'm pretty sure you need a new clutch and plate
so maybe the clutch and plate?? thats a good excuse to get the spec flywheel and stage 3 clutch i've been wanting.

Your car drifted to the left, then made a pop sound, and then went straight? Are you sure your diff isn't broke? Jack the car back up with both front wheels in the air. Leave the engine off and leave it in gear. Try to turn one of the wheels. The other wheel should spin the opposite direction and be nice and smooth.
A bad clutch shouldn't cause a car to drift one direction.
good idea, i'll try that. today I went out to the car to start it up and let it run for a little while, I heard a slight scratching sound so I pop the hood and there lies a possum. it scared the sh*t out of me so I start the car and let it run for a minute. I gave it a little rev, he got scared and ran on the header (which is pretty hot by now) scared this piss out of him literally because it was so hot and ran off. it was funny just thought id share.

If you put your car on a lift and spin the wheel by hand, you can't creat enough torque to make it pop. Look without seeing the problem in person it's always hard to diagnose correctly. But it seems to either be the diff or your cv joint. If you pulling to one side then once a popping sound it heard/felt..the car rides straight. I think the cv is wacked and starts to spin in the cuff, once it makes a pop it snaps back in place. Get access to a 4 post lift. take a long 3/8,1/2 extension and fit it between the seat and brake. Raise the lift with someone in the car, pull the hand brake to max..start the car up and try to advance. The car won't go anywhere being that all 4 wheels are locked with the brakes(if you have chocks fit them in place).
If your correct and the drivetrain makes a pop when torque is applied, you should be able to find it or pin point the problem
it's kinda hard to explain but you should get the picture
I put the car up on jacks today and put it in gear and tried to spin the wheel. it would turn about 1/4 of a turn then stop and not turn at all. the other wheel spun but the same direction as the one I was spinning. doesn't it usually turn the other direction?? I am pulling the wheels off tomorrow and possibly pulling the axles to get a better look. thanks for your help.

Ok so you had both front off the ground, spun by hand with the motor off and in gear. They turned 1/4 turn, both in the same direction. Then you couldn't turn the wheel at all..meaning jammed ..on both sides... am i following you??
its because hes in gear.... DUH... take it out of gear and try this test again.... it shoudl spin in opposite directions... the way he has it right now its trying to spin the motor with the tranny and i know any human cant do that.... take it out of gear and try again...

Ummm, no. If it isn't in gear the tranny spins freely and both wheels will turn in the same direction. WIth the tranny in gear, the gearbox can't spin and therefore the differential should spin. Hence, the tires should spin in opposite direction.
The reason why he can only turn the wheel 1/4 of the way is because it's in gear. The differential is an open unit. wtv the case is, it will spin the most easiest part that moves. Weither it be in gear or not, both wheels should turn in the opposite direction (by hand from the wheel and not turned by the pinion gear). some how both of the differential spider gears are jammed. thats why when the car is in gear and he try's to spin the wheels, both wheels turn in the same direction. the reason he can only turn 1/4 of the way in gear whould be, he is only playing with the slack of the gears in the transaxle. If he takes it out of gear(neutral), he should be able to turn the wheels completely around. But with the differentail problem both wheels will still turn in the same direction. I could be wrong with the fault, but i'm just trying to go with what the dude is telling me about his car.
firebug: Ne-waz..put the car in neutral and do the same task you performed before, if both tires still spin in the same direction but you can make a complete turn...You have a differential problem. Call around for another transaxle, unless you know of someone that can rebuild yours for cheap
I tried it again this time they both went the same way again, then the other one stopped moving and could only get one to move at the same time. so I pulled the wheels off to get a better look, I put it in gear with it in the air and gave it some gas. I had a friend hit the brakes with it still in gear, the whole axle stopped but the tranny and diff. just kept spinning. it got late so I am going to try pulling the axles out to see what is happening on the inside.
