Yeah, unbolt the shifter assembly from the top of the tranny. My lever was rusted tight to the tranny "nub" and had to be removed with an air chisel. You are supposed to be able to thread two bolts into the sides of the shifter with nuts on, then tighten the nuts and pull the lever off, but if its rusty, it won't budge.

Just an update. Spend the better part of thursday night and part of Friday installing the new clutch. Those reverse torx bits on the top of the transmission were a huge PITA to take out. Who ever invented torx bits should be taken into the street, beaten with a rubber hose, and shot.

When we finally got the transmission de-coupled from the engine I took a look at the throwout bearing (or what was left of it). There were ball bearings rolling around in the bottom of the housing, and the bearing itself was split in half and shredded. I can't believe the clutch actually even worked. The destroyed bearing had done battle with the fingers on the pressure plate and about 5 of them were broken off.

So we bolted the new one on, then I spent about 2 hours trying to get the tranny docked with the engine again (buddy was at work). Finally got it docked and bolted back on, replaced the crappy reverse torx bolts with normal 6 point bolts and re-attached all the sensors, driveshafts, etc.

When I fired it up it worked flawlessly, the squeal is totally gone. ALthough now that it's gone, I can hear another squeal coming from under the hood that is throttle related. I also got some codes after driving it for about 15 minutes - P0136, P0031, P0051 which are all O2 sensors.........bleh anyone know how much these cost to replace?

What I will say that if I can do this replacement.........ANYONE with half a brain and some time can do it. It's definintely helpful to have 2 people as it greatly speeds things up but I did manage to do a lot of the work myself, including re-docking the transmission. Thanks again to all that helped with advice!

The cheapest place I have found is www.oxygensensors.com and get the OEM fit not the universal fit.

Especially since the OEM fit will usually have the correct electrical plug and the universal fit will just have bare wires.

When you have a choice, buy American.

as for the oxygen sensors Napa downtown has them in stock I already checked with them about a month ago I think the most expensive one was about $120 to tell you the truth it wasnt that much cheaper than the dealer on Gregoire
