I got this done last week and holy cow the shifts were smooth as hell. We have the exact same car (08 sportshift roadster) so you will notice a nice difference.

I actually have an 09 6 speed coupe, but glad to hear you're noticing a difference. Did you go with the OEM BOT oil?

Have you guys experienced the same noise? Is it just supposed to be that way?
I've yet to notice any bearing type notices from the 6-speed nor 7-speed, not saying it'll never happen but being your on a 2nd transmission..I'd be thinking it's not trans related.

I've had a few driveshaft front and rear bearing go. Which this also wears out the pilot bearing. Not sure if the pilot wears first and then the shaft bearing or vise versa. So pilot bearing gets replaced along with sending the shaft out for replacement of shaft bearings...btw, this noise actually echos and sounds like it's inside the transmission.

Not saying this is your issue, but what I've had in the past.

So main questions.. "I have a V8V (ASM or Manual same thing), what gear oil do I replace it with"

From the factory, back 2006 the gear box was being filled with Shell 75W90, under testing in cold climates at -25C, the gear boxes were stiff shifting.

To correc the stiff shifting , SB0236 was released and BOT 270A was of the SB to replace the gear fluid. Castrol BOT 270A was used for it's a 70W, lighter fluid for colder weather. The Castrol BOT 270A is now ONLY available from your Aston Martin Dealer..(unless sourced from places like eBay).

The AM GT4 team suggests Castrol BOT 270A or Shell SAE 75W-90. In my area, Shell 75W-90 is hard to find in bulk for a dealer. being we have a Contract with Castrol, are reps advised us the best similar fluid to Castrol 270A and Shell 75W-90 is Castrol SynTec/SynGear 75W90 in Canada, in the USA this SynTec /SynGear is known as Castrol SynTrax 75W90. We have used the SynTec gear fluid in V8V's with no problem other than stiff when cold. This SynTec fluid is a choice we give to the client to reduce the service cost. If the vehicle is never going to be driven on cold morning/nights/fall/spring(below +10C), the client will usually favor in the SynTec..But price isn't a concern and the client doesn't want to deal with any hassle of stiff shifts, BOT 270A which is the correct fluid is used.

"I have a ASM vehicle, so I am not concerned about stiff shifting" ..True, but a missed shift can cost you $17,000-25,000. The ASM was been built and calibrated with 70W fluid in mind..if the fluid is thick/heavey and cold, a miss shift can happen..the ASM can't adapt for the possible stiff fluid like we can in person, after 3 attempts(strong forced hydraulic attempts) the ASM gives up and flags a fault..and now your stuck at the side of the road cycling the key to get the car moving again, only to realise you now have a bent synchro or linkage or ASM shifter unit...aka $$$$$$$$$

What I have found out from members on the board, the Castrol SynTec/SynTrax is not available over the counter..only sold to dealers via Castrol and possible available to the public if overed in bulk(5 Gallon bucket).

There is a Kendall additive available from A.M, this can also be sourced online. It has come to my attention that it is NOT REQUIRED FOR V8V, you can add it if you wish to use a 75W90 gear oil(don't apply to BOT 270A)..but is not required. It is however required if you change the diff fluid in a Automatic DB9 and decide to use a 75W90 gear fluid WITHOUT a LSD additive already mixed in. I have said in the past to use the Kendall additive in V8V's, if you have applied the additive..no worries, no damage, you can sleep at night..if you ever change the fluid again, it's really just a waste to apply for it's been noticed not to make any difference in V8V.


The gear fluid is replaced every 4 years or 64,000km(which ever comes first). So which fluid you decide really depends on you:
1: Do you mind the high cost in fluid, if this is not a question, put the BOT 270A
2:If the BOT 270A is hard for you to get, weither it be due to cost or area, you can use a 75W90 grade oil, but this is entirely your choice. You can try to source the SynTec/SynTrax, but it's all your choice again, if you drive the vehicle in cold and something does get damaged..you made the coice
3:People have used Royal Purple 75W90, the original Shell 75W90, Castrol 75W90..etc ..and have all had no problems. The gearbox in V8V's is used in Lambo's, Ferarri's..etc. They all don't use BOT 270A from Aston Martin. Aston Martin just had a concern to deal with(cold climate shifting), part of this was solved by using Castrol BOT 270A..you could always try sourcing the fluid from Ferarri or Lambo and input your results..I don't have any further input from that point of view


If I notice any faults in information, or if something you think I should add/edit to this information, let me know and I will edit my post.

Here is a picture of BOT 270A from Castrol so you know what your looking for, or trying to match:

Ruslan Batumelia Welcome to the 6speed community. I retired from the dealer life and now I'm part of the team @VelocityAP.

For your concerned issue, it's always best to open a new topic. Often the community has the answer or one of us as already touched the topic and answered in detail..someone might be able to link a reference.

I try to view all threads that haven't been answered, but my time lately has been getting packed at VAP with new projects. If you really need me to me look into an issue, just tag me in the post or feel free to contact me by email or DM.

Remove the drain plug bolt(14mm hex) and collect fluid to recycle waste oil

Once at a drip fit back the drain plug (washer can be reused if it's not oval)..

Remove the 8mm's that hold the filter screen in place(on LH back lower section looks like a small flat plastic cap, thats the filter screen) ..once bolts are removed wiggle the screen out but do not pry, it will break, its just a o-ring keeping stuck up...clean screen with brake cleaner and refit..you can replace the seal is you wish, filter is always reused unless it's coming apart..

From the fill port, fill diff with gear oil(see beginning of topic for spec').. till fluid starts to drip out, fit back fill port bolt..

Fit back the undertray and your good to go!!
I replaced the transaxle oil in my 2010 manual 4.7L V8 Vantage last week. It was last done in Dec 2014 by an authorised dealer. Just as I was starting the job and removing the fill port bolt, I had a bit of a nervous moment - quite a lot of oil (maybe 300 mL) came out of the fill port. I was working with an experienced BMW mechanic, and we were looking at each other like, "was that supposed to happen?"

Then when we refilled the transaxle, It took about 4.4L before overflowing from the fill port, the amount Irish mentioned in an earlier post. We left it at that, but weren't sure whether we should've squeezed some more in, before quickly popping the bolt back on.

Has anyone else had a similar experience with a significant amount of oil coming out of the fill port?

Maybe last time someone did it they were not on level ground... I did mine last year and it was just to the fill port maybe a few drip came out... Mine is an 09 Vantage with 4.7L and Manual trans
