Hey guys,

Having a few problems getting my box back in my GTST. Any tips? We're doing it on stands so access is limited :(

Had to change the pivot and did the thrush bearing while I was in there. Haven't touched the clutch so it shouldn't be out of alignment.

Any tips on getting it in?

If you know the right angle to put it in it will go easy takes me 5-10min to slide it back in on my own doing it on the ground basically tip is get the box positioned as close as you can without the spline hittin the pressure plate jack the box up keepin it on a angle and as you get closer you will have to slightly tilt it to clear the starter motor part once shaft is at right level push it in a little then you need adjust the jack to make the box at the same angle as the engine, if your using a tranny jack you can do it if not then youll need another guy playing with the angle from back of box and you play from front. With a bit of wiggling and twisting will go in no problem.

The angles have to line up in all planes or it won't go in. A couple of things we did that helped:

1. Suspend a length of timber or steel on top of jackstands inside the car (we had the passengers seat out, so 1 stand sat where the seat normally is & the other was in the driver's footwell), over the shifter hole, then use a cam-buckle strap over the timber, through the shifter hole, and around the gearbox. Use a trolley jack under the front of the gearbox. Now you can adjust the angle of the gearbox in relation to the engine. To get the angle right look closely at the gap between gearbox & motor all the way around - should be the same. Use a small block of wood or similar to confirm.

2. Put the gearbox in gear (4th) - now you can rotate the rear spline slightly as you push it towards the engine, thus also rotating the input shaft to "line up" the spline.

We found it much easier with 3 people - one adjusting the strap from inside the car, the other 2 underneath manipulating the gearbox.

      Old Son, did you re-use the Holden ABS in the new shell or try a different module?

      Another little story of weird shit happening

      Yeah, nah. I had the actuator rod off it today. The arm will not move at all. Neither out, nor in. Yeah, you'd think so, but I've been thinking about that. Even when the actuator rod fell all the way off at the beginning of this saga, it would build more boost and faster in lower gears than it would in higher gears, and you'd think that that was the opposite of what should happen. But I strongly suspect that there is a thing with the gearing getting the revs to rise faster, that there must be some transient effect with the gas flow rate rising quickly, that you don't get with the more steady state case of the higher gears. Keep in mind - the gate is not shut in either of my weirdnesses. So things are not "normal". We normally think about a turbo spooling up (below the wastegate target) with the gate shut. I have all sorts of mental models running now where the gate is a little bit open, and having it stuck open allowing gas out while it should be going through the turbine has all sorts of weird effects (in these mental models). I'm thinking in the higher gears, the ex mani pressure builds to the point where enough gases spill out the wastegate to just prevent the pressure rising much more at all, or just creeping up, all the whole the revs are increasing and getting closer to the point where a gear shift becomes necessary.

      Is it possibly wastegate actuator itself is sticking, or even the rod to flapper? Otherwise I reckon things are getting a bit rusty/worn   Also odd it won't boost in 3rd to 5th, but will in 1st, I'd expect the other way around with it slightly open as there's more time on your way to redline for it to spin up

      Does anyone know ow what these two plugs are for and if they should be unplugged? Just put the dash back together and can't remember if these were plugged in before or unplugged! (Blue and white plugs) 🤦🏽‍♂️

      Looking for a part number for this part here

      Did some FASTing ...got the impression that the actual part# was a moot point ; seems all of these hardlines for coolant are discontinued/NLA... like, I take it you're after the hardline that bolts onto to the manifold...that's NLA according to amayama & nengun .... ...just to clear up some confusion, they typically mounted the AAC valve to the intake manifold somewhere near a coolant passage, so the body of the valve heats up & holds it open when engine's up to temp - no coolant flows through the valve, it's a mechanical, thermal connection.
