I'm starting to have a few concerns about the longevity of my stock Mk I auto 'box if I get a fairly high power custom tune done. The car will be limited power wise by its otherwise stock components (only other change are a Typhoon CAI and BMC filter, but exhaust, injectors, etc, are all standard) so I guess I'm 'only' looking at something up to, say, around 260rwkw?

I have a fairly conservative driving style, but will still occasionally give it some stick (WOT) both from rolling and standstill starts. I'd be interested to know what sort of power others out there with completely stock autos are running, how long for, how they drive, etc, etc. I know the easy/obvious answer is to just strengthen my gearbox, but it's something I'd rather not do if at all possible.

Would I be mad to ask for one of Dynowog's 'mad' 98RON tunes that packs in a heap of torque down low, even if it was only used on special occasions? Or should I steer clear and not even be able to tempt myself with something like that?

I'd also probably be getting a 95RON 'power' tune and a 95RON or 98RON milder tune.

Best speaking to the Wog direct, I asked him the same question and got an informative and sensible response.

In short it is possible for your stock auto to survive with one of his "big" tunes but you will need to adopt a more controlled driving style I.e. no WOT from 2000 rpm in 4th for example.

I would recommend a trans cooler as the bare minimum regardless.

There is no such thing as too much ................

How did I just know somebody was gonna say that?!

My T was was running 280rwkw for the last 30k I had it . Auto was good as gold

with a valve body mod and tranny cooler. It also made several trips to WSID and was driven reasonably hard most of the time

That said I may have been lucky

Well with my driving style and gearbox completely std mine let go at 20,000k's with 250 rwklw(uni-jip)

Hi Bugster,

Ive done about 18000km in total, 13000kms of those at 247rwkw with no trans mods, not even a trans cooler, but the cooler was on my to do list. I drive quite enthusiasticly & have had no problems at all, even after about 20 hard laps of Winton & a day at heathcote. I think with good trans fluid & a trans cooler 260rwkw should be okay if you have the line pressure & shift duration set up with your edit.

Cheers,

Steve.

Thanks guys, very helpful stuff. It looks like I may have to consider at least a cooler, I do need the car to be reliable (I know, I know, why go the Edit then?! ). But it also seems that it's a bit of a case of 'luck of the draw'.

I think the problem with the Wogedit is not so much the peak power, but the bucketful of torque it'll be pushing out at low revs - that puts an awful strain on the transmission, more so than high peak power. But yes, will certainly go for the firmer line pressure, etc, to try and ensure the 'box at least has a fighting chance of surviving!

What sort of fluid is "good fluid"? or just use the standard ford stuff and replace more frequently.

my trans started to get a bit doughy at around 240rwkw and i had the valve body mod done and it survived to around 270rwkw. having said that my trans was one of the early ones that didnt have the kevlar clutched and bands and my right foot is made of lead so its pretty heavy. im not really sure how high u can go now with the new edit software being able to increase line pressure.

best way to go would be to keep cranking up the hp and torque till it fails then get it rebuilt at least then u know exactly what it takes to kill it......
