Torque converter lockup refers to the engagement of the clutch in the torque converter. When it's engaged the clutch locks both sides of the torque converter so that they rotate together. When both sides are locked together the transmission is rotating at the same speed as the engine. It provides better fuel economy at cruising speed.

As said above it can feel like another gear has engaged particularly if your line pressure has been increased or if the restrictive cap at the end of the input have has been removed.

Ahh wicked, cheers.

I ordered a new PCM hose... does that sound right?
Anyway its the hose from the throttle body to the rocker cover.
quite thick with some weird metal thing on it.
Mine has a small split in it, would this cause many issues ???

Id say you mean the PCV=Positive Crankcase Ventilation hose.It will cause the engine to run a bit crook if the hose is split and it is sucking air in through it.

Ah cool, I guess replacing it's gonna be a good thing then

Okay PCV, TPS and IAC fitted, seems to have fixed all the issues I was having around the ####ty shifting and varying idle.

Car still does a random 1 off idle fpm increase then decrease and then it's fine. Not sure if this is standard, but I can deal with it nevertheless.
