It sounds like the clutch is completely gone, you will need to look and see if the clutch release bearing is moving, if it is then the transmission must come out and the clutch replaced.

it sounds like you need a clutch

The transmission is worn. The cheapest fix is changing to a high quality synthetic fluid. This will allow for easier shifting when it is cold.

sounds like a bad tranny. Gear shifter may be locked, have you checked the tranny fluid?

check the abs pump fuse .the abs pump or a sensor could trigger it. get a scan done...the code will tyell you what is wrong

I had the same problem. A spring in the gear change selector had broken making it impossible to get into reverse and very difficult into first to fifth. Simple repair. Might be similar to your problem

Hi mate. I'm no Porsche expert but the most common diagnosis would be clutch failure. If you can shift (even some) gears with the engine off then this would be plausible. Before looking at the complete clutch, try the master and/or slave cylinder, it's more likely to be the master. Pop the bonnet and check the level of brake fluid in the reservoir, there is no "clutch fluid", it's just brake fluid. If it's below the minimum line, top it up then see if it engages gear. Get it checked out, but tell the mechanic your theory, he'll soon confirm it if it is.

I build turbo 350 transmissions. Can you give me more info? Almost always you will have a reverse as long as you have 9 1/2 quarts of transmission fluid. Now if you do not have reverse or a drive and it is full you have one of two problems. A bad (blown convertor) or the pump gear is broke. The pump usually goes out over a coarse of a week until it can not build pressure. The Convertor is usually the stronger piece and makes a shotgun BANG when it goes out. I really need to know how it was acting a week or two before you just had NOTHING. Can I have the style Lock up / non lock up? The year model would help too.

Refill and bleed the clutch master cylinder.
