Does anyone have any info on changing the gearbox oil on a 964.

i.e.

type of oil ?
amount of oil ?
how to drain ?
how to fill ?

cheers

Tony
 
Tony,

Type: SAE 75W/90 Gear Oil (API class. GL5 (or Mil-L2105B)
Amount : 3.8 litres
Drain plug under gearbox
Fill/level plug on side of gearbox

NOTE: Please, please, please make sure you can undo the fill/level plug BEFORE you undo the drain plug!!!

If you've got a C4 the same oil (1.2 litres) is used for the front diff.

Regards

Dave

Wise comment Dave,
If you open the drain plug and drain the oil and you cannot undo the filling plug then you will be in trouble as you will have no oil in the gearbox.

Hi

Just changed mine.
wise words from Dave about the fill plug.
Make sure the allen key used is in good condition before attempting to undo the bolts.Mine were really tight and needed a bar to be put on the end of the allen key.

I used a hand pump which i bought from machine mart to get the oil back into the gearbox worked great and made little mess!!

Hope it goes well

Have decided to go for a new clutch, then I know all is well and should have trouble free motoring (cough . . .cough [8|]) for years to come.

Having trouble getting 1st, 2nd, crunchy in 3rd and no reverse. Even with the clutch fully down, and the car in gear it still tries to move away.

I`d love to believe that a gearbox oil change would change this, but even though It`s booked into Strasse for a clutch next week my local garage tells me that changing the oil will make no difference.

Should I just change it anyway and see if it makes any difference ?

thanks

Tony

 
Tony,

From your description it sounds more like the pedal/hydraulics/slave cylinder are not releasing the clutch properly. This is likely to be the roll pin problem on the pedal, air in the hydraulics or a problem with either the master cylinder or slave cylinder. If it were the clutch itself I would expect it to slip when power is applied - pretty much the reverse of what you seem to be experiencing.

If it were me I'd be having the hydraulics checked and bled before I committed to a major expense of having the clutch changed. Better an hour of labour than £1000 of clutch change.

Regards

Dave
 
Thanks for the call Dave, have drained the gearbox oil and on with bleeding the hydraulic system now [;)]

Harry, what are the seats in your sig mate ?

cheers

Tony
 
Tony,

Did you not receive my e-mail? They are Recaro bucket seats which were standard equipment for RS variants. Recaros make similar seats called SPG and Pole positions. Occasionally the original seats come up on e-Bay and they cost big £! If you are going to use the rear seats I suggest you don't put them in for safety reasons.

Harry
 
No mate, no e-mail. I`m not using the back seats anyway so I`m going to go for a set of these if I can get some.

I need to change my carpet and want to replace my doorcards so any info would be greatly recieved.

cheers

As Harry said, the RS seats are like Hen's teeth to find. I put new Recaro leather/suede PPs in mine. Including sliders and sidemounts they were probably half the price of used RS seats:

p.s. hope the slave bleed works - it did wonders with mine (but getting your arm up there is a bitch [:D]).

All bled now, new oil in the box so will see how it goes. Is changing gear now so definate improvement, still up on the ramps so have`nt tried it since slave been bled.

Have checked out the link, are the black seats in the main pic leather ??

Yes leather trim and suede cushions. I think you can get all leather but I've only found them for sale in Europe. Quite expensive too!

Leather Pole Positions at FVD
 
I don't think the suede cushions detract from the looks at all and it is probably warmer in the winter. When the time comes to replace the cushions you can get them reupholstered at places like Southbound trimmers and they can also provide and fit new carpets. As for the doorcards, if you want the RS ones you can go to OPC to buy them new, buy from Southbound trimmers or make them yourself - go to Rennlist site and search and there was someone who actually made his own.

Harry
 
I agree, would prefer sued seat area anyway. What about sub frame or `runners`, do they fit straight onto the ones already in the car ?

Been on this site : www.sportseats4u.co.uk and it`s showing £1313.00 for a pair in leather with suede insert, niot sure if this includes everything to fit them in the car.
 
Has anyone used Swepco in their 964? I used it in my previous 911. Worked a treat. Berlyn services recommend it for the 911.
 
I used swepco in my g/box from berlyn...

cant comment what it is like at the moment as I am still doing major surgery to my 964!. Just about to order the big red kit for front with 965 turbo discs and rear 965 turbo calipers in red. Rears are going to be machined to work with standard 24mm discs. Need to fit my new shock kit as well as finish the full service!. Should be good when finished!

Dave, I`ve noticed that the problem is worse as the car gets up to running temp. From cold its not really noticable, but half an hour later it`s really hard to get into gear.

Is there something I could check or replace, which is affecting the gearchange as the car warms up? Could I get Strasse to check the slave before replacing the clutch ?

thanks
Tony
