It looks like I need a transmission rebuild

[husker boxster]

I've got an unusual 3-2 downshift crunch in my CSS 6-spd that I suspect is a 2nd gear synchro. I've been snooping around to see what it would cost to fix and like you have found no one wants to work on it. The only place I found that would was in CO but it was going to cost at least $5K. With my engine rebuild going to cost an astronomical amt, I haven't pursued spending more on top of that. I'm sure I kept the info on the name of the place in CO if you're interested, but it will take me a while to find it.

No, it made no noise before I pulled it. The trans shop I took it to (local place that's done good work for me, but not a Porsche specialist) is thinking something came loose when I pulled it.

Here's what it sounds like running: https://www.youtube.com/watch?v=EWWvBP2g1T4

For the record, I get that noise with the clutch out, and when the car is moving (clutch in or out). If the car is stationary with the clutch in, it's nice and quiet. Hence why I have pulled it 3 times looking for clutch/flywheel/release bearing issues.

I used Porsche OEM gear oil I got from Pelican. This stuff: https://www.pelicanparts.com/More_Info/00004330549.htm?pn=000-043-305-49-OEM

I filled it according to the instructions in the 101 Projects book.

Husker, taking my car (987CS) to the track for two seasons with the POC, I ruined my pinion bearing, perhaps for not installing a transmission cooler and sent the gearbox to GBox in CO, while it was that shop I decided to install an OS Giken LSD as well, but when I received the gearbox I noticed that they stripped the head of one of the bolts of the input shaft flange, and the shop didn't bother to replace it..,

This shop also didn't return the open differential when they shipped the transmission back to me and after I complained they simply told me that they could not find it and I could not do anything about it.. however the worse came a few months later after I lost the ability to engage fifth gear (..!!)

After removing the transmission I decided to bring it in person to CMS (California Motor Sports) in Lake Havasu, AZ and they kindly open the case while I waited, and reveal that the selector fork for 5th gear had lost it's locking pin, and that pin was loose inside the gearbox for the few days I was using the car without been able to engaging 5th gear

Needless to say I would Never consider sending a gearbox to GBox for their poor craftmanship and terrible customer service.. In the other hand many of the SoCal speed shops praise the quality and professional support they get from CMS, give them a call and you will be surprised that you may not need more than 2-3k to rebuild your gearbox https://californiamotorsports.net/

Good luck!
