Clutch/Transmission problem

I cant remember which one the mechanic said but he said since he was taking out the tranny he suggested I might replace the slave cylinder, and he said if I look to get an aftermarket pressure plate or clutch that it would handle the extra pressure, so I would just get it out of the way now

First rule of maintenance - if it ain't broke, don't fix it. *shrug* To me, that's strike one against this 'mechanic'.

P.S. I've seen the mount point for the clutch fork get broken in the past, and could fit with your description of symptoms. This problem can be verified via the inspection port (i.e. without transmission removal).

So what ended up being the problem were a few things, I needed a new drive shaft because i think the U joint was bent, so I got a stock replacement from horsepowerfreaks. The second was pressure plate failure, so I got the rps pressure plate. And then I am replacing the tail shaft seal because of seepage, and he said that there was something with the slave cylinder, i cant remember off the top of my head, but he suggested I replace it, and so thats why we were doing that. All in all its going to cost me between $2000 to $2500 with parts and labor, and I bought all the parts online, the mechanic was a big help. And hopefully if all the parts come in ontime I will have my car back running perfectly by Thrusday Friday next week!

I'm glad you got everything diagnosed. Seems like a lot of $ (I know 'yota labor isn't cheap). Also the problems you're describing are very, very rare (eg. mkiv TT driveshaft u-joints just don't bend - never seen this happen even at high boost with wheel hop - I've seen several driveshafts that look like licorice in the middle, but no bent u-joints). Although the problems are rare, it seems they did happen - to your Supra. Good luck with all of the repairs and I hope it all runs great when they're done.

Oh, and the bent u-joint doesn't fit with the symptoms you described above *shrug*.
