915 gearbox issues
Discussion
as above,
I let a friend have a drive last night, he kept forcing it into gear instead of waiting until it was ready. I actually stopped him driving it after about 2 miles due to it.
Now I have an issue which literally started straight after.
It changes great as usual all the way up to fifth, however once in fifth I cant get it out. Its locked in and until I force it it wont come out - and I really have to force it.
There is no crunching in any other gear and reverse works fine.

I'll keep an eye out for you in the news ("Man shoots friend for damaging Porsche")! Make sure you pass him the bill, I bloody would.

Hi may be just the shifter coupler slipped, it's behind the seats, pull back the carpet and there is an inspection cver to remove to get at it.

Get your self across to impactbumpers.com-loads of advice on this.
Before you start stripping things down try twisting the gear lever straight again. What can happen is the gear lever rotates in the receiving socket. You need to hold the base of the lever below or just on the curve then rotate straight using the gear knob. You are looking to get it aligned fore and aft with the car.
I have bought 4 speed cars which suddenly become 5 speed cars again once the lever is aligned properly
I'll bet you a bottle of something cold that is your problem.
Good luck.

The 915 gearbox is fine on early cars. It has a slower gate than the G50 and is best not rushed. Fitting a short shift reduces the gate but generally worsens the change quality.
The 915 actually feels better (more natural) in lhd 911s, where only 5th is a reach.
It is lighter, and Dr Konradsheim apparently had a pre-production 911 'Club Sport' with a 915 gearbox that benefitted from less weight and parasite drag.
Personally, though, if I were looking for a 3.2 Carrera, I'd rather have the G50 and hydraulic clutch.

My old Targa had a rebuilt 915 gearbox and aside from being a little bit stiff going into 2nd from cold it was faultless for the 3 years I owned the car.
I had read that the G50 was the stronger of the two however I grew to enjoy using the 915 box and always treated it with mechanical sympathy. Anyone using or having a go in your car really should be treating it with utmost respect IMHO.
Good luck OP!

Henry is bang on. Mike Chadwick, with all due respect is confusing the issue and has clearly not tried a 915 with a correctly fitted FACTORY shortshift
- actually, my 915 does have a correctly adjusted factory s/s, fitted by Jeff Moyes. The guys at JZM pointed out the problems with a s/s, so I had it removed temporarily, but later had it re-fitted, and now understand the differences.
Agree, the whole selector fork, actuator mechanism needs to be correctly adjusted and lubricated, but still pays not to rush it.

I noticed yesterday the gear diagram was at an angle - I will try this as soon as I get home. thanksI have bought 4 speed cars which suddenly become 5 speed cars again once the lever is aligned properly

I have spoken to the only garage here in NT that deals with Porsches, He is telling me its the bushes.
Is this correct (he has exactly the same info as posted on here). I dont trust the guy but there is absolutely nowhere else I can take it.
If it is the spot weld thing, is this easy to do? how do I access the gear levers to have a look?
sorry to be a pain but I have never worked on anything like this before and I am a little worried about making it worse (undrivable)
thanks

You need to lift the gear shift rod gaiter to have a look at your gear lever. There is also load of advice on pelican about checking and changing if needed the various bushing in the shift linkages.
fixed with spotweld - the mechanic was telling me bushes needed doing etc etc.
30 minute job with a mate who is a welder - 29 minutes 35 seconds to move upholstery and 25 seconds welding.
cost = 1 beer
quoted cost by mechanic - (teeth suck noise) its gonna be expensive.
wonder why alot of mechanics have a bad rep??

I'm always a little wary with this attitude. Yes he could quote zillions, but then he could have got a welder out like you have and quoted a few quid. But if he quoted a 30 minute job and it wasn't, then what happens?30 minute job with a mate who is a welder - 29 minutes 35 seconds to move upholstery and 25 seconds welding.

I make furniture for a living, and that 10 minute quick job a punter believes it is, can easily become an all dayer if there's more than meets the eye when you start.
Not trying to cause trouble, just sometimes it's easy to imagine that someones trying to rip you off, when in fact they are either not, or covering for the unexpected.
Saying that, if he charged for an all dayer and it only took 30 minutes. Well he's a ripping off slime ball.

I agree normally but..... previous experience dictates he is a ripping off slimeball. I vowed never to go to him again but needed work done fast so thought I would give him a second chance. I fully explained along with advice from other owners. mechanic kept stating I was wrong and definately bushes. I let him go for ages. It concluded with him telling me he was ordering the bushes despite me saying- 'don't you want to have a look first'?? I repeated the symptoms, the fact up until this sudden problem the gears were 100% fine and bushes had not long been changed.

If he had a look (and I would be more than happy to pay for his time) and then said 'bushes' I might of listened.
this is the same mechanic who charged me nearly $1,000 for a two hour labour job (single person) with all parts supplied!!!!!
