Car keeps slipping out of fifth gear.

[Ext User(Some Guy)]

Howdy,

I drive a 1987 Nissan Pulsar Q (which has been a great little car). Lately
when im on the freeways the car kees slipping out of fifth gear into
neutral. I either have to push it back into 5th or just hold it in place so
it doesn't slip back out. This is getting really annoying :/

Obviously I have gearbox problems. Anybody have any idea what it's going to
take to fix this? Im assuming i'll need to have a reco gearbox fitted, what
sort of $$$ am I looking at if I want to drive it into a mechanics and have
the old gearbox taken out and the reco one put in?

Any other solutions? ie. repairing the current gear box?

unless you are confident about removing your engine and gearbox and
pulling the box apart to replace the bearings then leave it to someone
who knows what they are doing

maybe go see a wreckers, they will even install it for you for a fee

Octapus strap $1.95. ;-)

But seriously, I had a similar problem on an rx5 gearbox. If it's a rear
wheel drive car then removing the box isn't too difficult and you might be
able to get at 5th gear bu just taking off the extension housing. If you're
not confident in doing it yourself most likely you can get a mechanic to
just fix 5th gear and avoid the cost of a full reco.

I'll mention that to my 25 yo girlfriend. When I show her your photo she
should get a good laugh.

unless your competent it means getting assistance , prolly a selector
fork but I am not familiar with the car so it might be a syncro or
bearings ... grab a manual and find out how hard it is to remove the
motor and box and split them , it was easy on a mini but this car I cant
help .

Haynes don't list a manual for this year Pulsar in the list at
http://www.haynes.com.au/category156_1.htm

But you can buy one for the European version, called the "Nissan
Almera". There are differences, especially to the engine inlet
manifold and associated peripherals. I got mine from
http://tinyurl.com/ylz5gj

It lists 3 possible causes of jumping out of gear: worn or
damaged gearchange linkage, synchro units, and selector forks.
It suggests the first is within the capabilities of a
"competent DIY mechanic" whereas the others are not.

I had an old Sigma that did that.

It would hold 5th under power, as soon as you back off, out it came.

It was apparently due to a sheared bolt holding the 5th gear sprocket on
the end of the layshaft.
The helical gears would hold under load, but throw out when the load
reversed (backing off)

5th gear was inside the extension housing as someone else suggested, so
did not require a full strip down.

As for doing it on a front wheel drive, dunno, the Sigma was RWD.

You haven't indicated its mileage or service history but you'll
almost certainly have damaged synchro dogs on that particular gear
(read rooted). Sadly such damage can often be avoided if you're able
to recognise the onset of the problem, which usually has another
cause, such as linkage adjustments. Whatever the initial cause, if
you've kept on driving it when it won't stay in gear then the damage
is done.

Assuming that's the only fault, it isn't likely to be particularly
difficult to fix once the gearbox is apart... if you could find a
mechanic who's prepared to approach it that way. Most won't. A large
number of them won't have the necessary experience to assess the rest
of the box, and those that do probably won't be bothered (they'll also
be far too busy looking after their regular customers).

Expect big dollars for a major rebuild, and you'd also need to be
very, very careful who you entrust the job to. Unless the rest of the
car's in exceptional condition (and very few cars its age are) it's
probably time to replace it.

Them's the sad facts in 2006.

I don't know about the Pulsar specifically, but in a lot of
cars, prolonged holding or pushing against the gear lever while
driving causes the wear which does the permanent damage. It's
a bad habit a few people have.

Could be something as simple as a detent spring......may not even
require dismantling the box.

Which causes the selector forks to wear so that the synchro dogs
don't then fully engage when selecting the gear. Once it starts to
slip out of gear the end result is the same -- the synchro dogs (the
teeth that do the driving) rapidly develop a taper... at which point
fixing the original problem (which is usually a relatively simple
repair) won't eliminate the fault.

I don't know much about the Pulsar specifically either, but it's a
common enough fault across a wide range of makes, both front and rear
wheel drive.

In fact, very few cars ever wear out... they're driven to destruction!

mate you have done the rear engine mount whats happening is the engine is
sitting back not allowing to engage fitfh properly and why its jumping not a
big job just somthing thats easier done on a hoist for acess.

Hi,
I'd be checking engine mounts first, esp the one to the rear of the
engine. Can cause exact problem you have. If it goes back into gear after
jumping out normally, without crunching and without too much force, you are
in with a chance of it being a mount.

Very true, the cost of a gearbox rebuild would be more than the cars worth.
Buying and fitting a sh gearbox is a risk but will be a lot cheaper.
