improving/strengthening qtronic

Hi All,

So I have my 2.4 qtronic remapped by the ever patient and helpful team at Autolusso.

And the queries in the alfa community over the strength of the qtronic come and go, and I did a bit of reading around and things.

It seems there are two ways to improve the torque handling ability of an auto. more friction surfaces (i.e. more clutch plates in the box to engage the gears and transfer the torque from torque converter to cog) and adding pressure to more forcefully engage the plates to reduce any potential slipping.

Now the former seems rather complicated and prohibitively expensive and probably not possible, which leaves the second. As I understand it how the gearbox fluid moves and engages bits is controlled by a computer and a solenoid and something with many valves and flaps, and these can be upgraded to work by presumably more fluid operating at a greater pressure.

Am I on the right lines with this, and does anybody have any thoughts on the matter? it doesn't need to happen often for a slipping plate to ruin your gearbox I don't think....

No thoughts, but mine very often slips or rides the gears even after changing the gearbox oil at consecutive services. I know it doesn't all get changed each time, but trying to find someone who proclaims to be an autobox specialist who can do the "Gibbons method" of a total flush doesn't seem to exist in the North West.

One day perhaps...
