Okay so its going into all gears fine, but the clutch is slipping so bad it will barely make it up my driveway! I just read that possibly overfilling the trans can cause this, car ran with no slipping for 1 day, then when i started it the next day it was slipping.

Also It makes a loud noise whenever i press in the clutch...
Throw out bearing?
Slipping in every gear even reverse, no smell or smoke.

Sorry just kind of ranting, I really want to get this car running again, I just want to have all the transmission work done right at once, Should I replace all the bearings? Had a bad mechanic take 5 months to replace my transmission, should still have my old oem replacement exedy clutch and pressure plate only has about 15k on it.

Bump, I guess because of the lack of responses I may need to just take it in to a shop and redo everything, but if anyone can help me with what is causing the noise *ONLY* when the clutch is pressed in, that would be amazing.

Should only use OEM throw out bearings.
Your description of a loud noise is also not very helpful... Banging, scraping grinding clucking?
Was the flywheel reused? was it stepped to the proper 0.608--0.612?
what clutch was used? what pressure plate? what flywheel? what throw out bearing?
Just need a little more info...
And on another note, if you have minor wrenching ability you can do this yourself... save your money.

My buddy works at mobil 1 so Ill hopefully take it in there, then drop the transmission and replace everything, ignore the blue tape and lack of a power steering cap. Replaced the blue tape with another filter, and got a new Power steering reservoir cap... (Yes I'm on speed density tune with gm 3 bar, and not using a MAF)


Exedy clutch and pressure plate P/N 05071 stock flywheel, not sure about step, I've yet to do the transmission myself, was paying people to do it before. The Clutch was working before fine on my old transmission with more power then I have it at now. Had a similar noise before but more grindy. Now I have a 94 transmission, and clutch is slipping, I know its all properly adjusted, did that myself. Bled it as well.

Was the fork shimmhed? Sounds like fork is hitting the pressure plate. Can you push the slave back in by hand?

The input shaft seal could be bad in the new trans causing the slipping but not the noise. The noise could be from loose pressure plate bolts, quite when under tension from the pp and loose when clutch is pressed. Only thing I could think of is the disk got misaligned during the trans install, he loosened the bolts to align the disk and didn't get them tight when finished. Since the pressure plate bolts are loose the clutch isn't fully squished which is why its slipping. A fork pivot ball that needs shimmed would cause improper clutch disengagement not problems with clutch engagement. Paul is right, if the pivot ball needs shimmed it could offset the angle of the fork causing the fork to make contact with the pp but usually this happens when ppl accommodate an unshimmed pivot ball with an extended slave cylinder rod.

I would check the obvious.. sounds like a shoddy mechanic I would check the trans mounting bolts. Second I would make sure the water pipe support isn't in between the block/trans and is on the outside of the trans or the bell housing is prob cracked.

As far as he told me, There was no actual problems installing or anything, and I had the car running for 1 day with this new transmission no clutch slip, So The two aren't related issues imo. Yes i can push the slave by hand but I couldn't get it to lock up when adjusting.

Check the slave again. Just because it didnt slip on day one doesnt mean anything. What were are trying to determine is that the clutch is fully engaging. If its fine that leaves step height ( you did check?), worn clutch or contamination. The noise is obviously mechanical and will require a trans drop.

One other posibility, awd bad viscous or an axle that pops out of place will feel like a slipping clutch.

Ive checked the slave again it still goes in and I haven't ever seen the flywheel yet. I followed jacks trans guide for adjusting and with the rod under the dash fully adjusted it didn't lock up the slave like he said it should. It will still push in, does that mean its not working properly? Sorry I'm a ricer. .

It should push in. It just means that the clutch is engaging. Slipping in reverse is wrong. Sounds like something other than clutch. Did you check axles? Was this Trans from a running driving car or unknown?

it was running and driving and its slipping in every gear.

In jacks video he adjusted until it locks then backed it out a turn so it would push in. I couldn't get it to lock so mines just adjusted all the way out, clutch petal feels like normal, slave will push in.

If car wont move even at light throttle its either driveline as mentioned or a contaminated clutch. Cant think of anything else given what youve already stated. Check that axles are seated. Any chance that trans was in a car that was towed? Do you know the whole history. Im assuming youre awd.

it moves, juust slipping badly, barely makes it up my slanted driveway.

Check what I mentioned

Wow okay, I checked out the axles and was surprised to see...

The axles mount isn't even mounted on the drivers side, not one bolt, tried to line it up and its more towards the drivers side wheel, any tips on moving it back over, or should I just wait till I pull the trans? also its leaking badly, all over the oil pan.

Stuff it back in the trans and see if the problem goes away

Good that was my thoughts, tried to do it with everything still connected and no luck. haha Gonna drop t case and get it back on there. thanks for all the help everyone. Ill update asap.

Anyone know what size bolts to use? Couldn't find it in the 1G fasteners list.
It went back in, should fix the slipping problem

If your not running AC(ac bracket removed) you will need a spacer on one of those two bolts. If the spacer isn't close to the correct size it will get the mount in a bind and the bolts will either break off or come loose. I machined my own spacer but you used to be able to buy them.

2G:

Front Axle Halfshaft Bracket to Block Spacer MD748352
Front Axle Halfshaft Bracket to Block Spacer B MB297732
Front Axle Halfshaft Bracket Bolts MB297860
Front Axle Halfshaft Bracket Bolt Washers MF450406

Are those 2g parts? Every 1g I've worked on only had 1 spacer and the 2 bolts are different lengths.

1G:
M10x1.25mmx41.5mm pilot point bolts (x2) = MB297860
M10 lock washers (x2) = MF450406
Halfshaft spacer = MB297732

So they are the same bolts... Hmm Thanks Tim!
