db9 transmission cooler

[ian448]

Ive an early DB9 and have noticed that the two rubber transmission cooler hoses have started to weep slightly. I know its a common fault and Aston brought out a kit comprising of upgraded lines and a new cooler.
Has anyone had the job carried out recently and if so which garage did the work and how much was it ?
I know the kits around £800

Ask a farmer, they use companies for oil coolers and hoses etc, think JCB.

I replaced my rubber lines myself last year, I used these -

Just a couple of meters is all you need, just £20.

Or, HWM have a genuine Aston set for £404, without the cooler -

After the rubber hoses have been replaced the very important job is to top up the ZF gearbox fluid, this needs to be done using ZF lifeguard 6 fluid and the top up procedure is quite complicated.

Did wheeler dealers not do this when they refurbished one. Big Ed had trouble separating the hose from the cooler and burst the cooler. Probably why AM supply both as a kit

thanks Paul , The hoses appear to be crimped onto the pipe on one end, Im presuming its just a matter of cutting the crimped end off with a dermel or similar , replacing the hose and securing with jubilee clips ?

Yeah that's right, get genuine jubilee clips
