Installing A Transmission

[J9000]

I guess I am one of the few lucky ones to have a bad transmission.. my 1999 996 2rd gear simply keeps failing.. hard to engage..etc. Rector said I had a bad transmission and the repair cost will be enough for me to buy a 997 instead..

So I found some from 911pcar.com, a junk yard that sells parts. They have the whole transmission, and even engine) but I need some guidelines/thoughts regarding how to do this cost effectively.

Unfortunately, Porsche does not sell parts to repair the G96 tranny. so replacing it is the only option when something fails. The tranny on my 1999 also failed for its new owner but fortunately I had transferred my extended warranty to the new owner.

I think your options are to get a factory fresh tranny from the dealer or to buy the used tranny and hope it lasts. You probably want to consider how long you plan on keeping the car. You can probably save a little on labor by using an independent Porsche shop instead of the dealer but this is not a cheap job to do in any case.

Buy either a used or rebuilt. If it is a used one see if you can determine how many miles are on it. A used one should cost somewhere between $1500 and $2500 and a rebuilt $4-5K.

I broke my tranny (1998) 2 years ago and found a used tranny off of a 1999 that only had 2000 miles on it. I figured it was just broken in. I then had an independent shop put it in. You will hear all kinds of numbers as to how long this takes. Anywhere from 3-10 hours. (I think it should take about 8 including replacing the clutch.) Multiply by the hourly rates in your area. I have 20,000+ miles on the tranny now without any problems.

While you are in there you may want to have the clutch and/or flywheel replaced.

Be advised that a rebuilt one from the factory only comes with a 2 yr warranty (I do not know how many miles) and in my case the dealer would not warranty it at all because I track my car. So it made no sense to get the rebuilt one. The used tranny only had to last 2 years (which it has) for me to be ahead dollarwise. YMMV.

Some parts for the Getrag G96 gearbox are avaialble from the parts counter. In particular the bearings, main shaft, seals and even some of the gear cogs. But by and large only a fraction of the parts are available from Porsche parts. The other thing to do is to find a good independant who has a stock of duff gearboxes which he can maybe

pilfer the parts from to fix up your gearbox. This is what I am doing.

My independent Tech9 Motorsport in Liverpool, UK specialises in building race cars. They take the standard gearbox out and replace it with race spec versions. They have a small mountain of used gearboxes....none of which are complete....from which they will be attempting to rebuild my gearbox from. There is no guarantee of course that they will be able to get the part(s) I need from their gearbox collection but the chances are extremely optomistic.....and besides, if they can't get the bits then he will source a good used one and replace it in whole.....which is what I would have had to do anyway. It's worth asking around.

Thanks guys.. Does anyone know a good shop in SF bay area that I can try? I was thinking about getting a used trany from LA and have someone here install it. But Scouser could be right. I may just need some parts here and there (save money).

Anyone knows how to switch 1 -> 3 -> 4 -> 5 -> 6 and still maintains the 5 seconds take-off to 60 mph

The problem with trying to fix your tranny is that the tear down and rebuild will probably cost about the same as just buying a working tranny. Obviously the removal and installation cost is the same. If you repair your tranny the shop has to disassemble it, figure out what is broken, try and find the parts and then put it back together. Talk to some shops and see if they can give you an idea on how long/how much this will be.

The Racers Group in Sonoma is a good place to start. Depending on where you are in the bay area there are a number of other places.

Hey

If your looking for a transmission you might want to consider these guys.

In Los Angles, these folks have lots of take off's.

It's sort of sad that with an expensive car like the 996, the transmission cannot be repaired by anyone other than the factory. I hope this changes in the future, as the 996 cars get older the demand for replacment parts will be tremendous, and I know there will have to be parts released for internal engine and transmission repair. Would'nt it seem So?

I do not think that it is a question of being able to repair the transmission. It is more a question of can I get part XXX. Eventually it will happen, just may be a while.
