1987 saab 9000 turbo transmission

So you installed a new transmission and a whole new clutch kit? Did the kit include the pressure plate, clutch, throw out bearing and slave cylinder? Did you bleed the slave cylinder? The low and soft pedal is a clear sign that there is air in the hydraulic system. The loud noise after that tells me you're either grinding the gear trying to shift or there is a problem inside the transmission itself. If you installed everything correctly and torqued all the bolts correctly in the clutch assembly and transmission, then try bleeding the slave cylinder again, sometimes air gets trapped in the cylinder and it's hard to get out, If you let the clutch master cylinder run dry while you either had the clutch apart or while you were bleeding the clutch, then you have to start from scratch and re-bleed the whole system.

sounds like you still have a hydraulic problem with the master or slave cylinder air getting in the system or perhaps the clutch pressure plate is packing up

Check the hydraulic clutch operation. This is a clutch master cylinder with a reservoir on the firewall, and a clutch slave cylinder down on the bell housing of the transmission, with a steel tube running from the master to the slave cylinder. When clutch pedal is depressed, hydraulic fluid (brake fluid) is forced from the master to the slave. The slave cylinder should push out a little plunger that contacts the clutch fork lever-pushing it forward to engage the clutch.
Add brake fluid to the reservoir if needed. Watch the plunger on the slave cylinder: if it moves little, or not enough, try bleeding the slave from the bleeder valve. They are bled just like brakes. If bleeding doesn't help, your clutch master or the slave may need replacing. The master cylinder, like a brake master, has internal seals that hold hydraulic pressure, so force can be applied to the plunger on the slave cylinder.

Hi, There is a bleed nipple on the slave cylinder which is located on the underside of the bell housing. Cheers Ralph

Could be your clutch slave cylinder is bad,check your clutch fluid,if real low or empty then it is bad,it's located on the side of the transmission with a hydraulic hose connected to it,I have a 85 Nissan 720 4x4 5- speed,had to replace mine a few times.Here's a link on how to do.

Get the clutch slave cylinder and master cylinder looked at.One of the 2 has failed.If the pedal goes to the floor or is very loose,this is very likely the cause.Not an expensive fix.Hope this helps

Sounds like you either need to bleed the clutch slave cylinder, or you need to rebuild or replace the clutch master cylinder and slave cylinder. You might want to check with the shop that replaced the clutch and rebuilt the transmission. It may be covered under their warrantee.

Jack up the car with adequet support have someone work the clutch in and out,obseve the slave cylinder when the clutch pedal is realeased--is it free or hanging up -still tight then problem with the master or slave.If not then the clutch plate may be stickly on the splines when cold,

Clutch pressure plate might be coming apart but be sure to check the clutch pedal pivot and mounts. I've seen firewalls break and cause this problem.

I would first bleed the tranny lines, if that doesnt work then your tranny is out and need to get it replaced. FYI with Jeep Wranglers, It is better to get a new transmission then to rebuild them
