My failsafe trick I invented? (i've never seen a video of it or mention of it) 
is to get fish tank bubbler hose or clear hose from bunnings etc (not sure what it's used for, but i'd call it one man brake bleeding hose)   basically get s bit of rubber hose that fits over the bleed nipple and also the clear hose fits in..
make sure the brake reservoir doesn't get too low in the process, but basically crack the bleed screw and gently push the brake pedal down and slowly up and watch the air bubble go the full length of the hose and even back to the master cyl if you have a long enough length (2meters is enough to watch the bubble/s until there's no more from the drivers seat.     

Its now officially on the road! Even I still dont get how it passed with some of the rust and bushings but its now registered. Tomorrow ive got a bag of bushings to install ready for a 2hr trip on Sunday, Im also gonna try an idea for a power bleeder to try and get a pesky air bubble out in the rear brakes, so if it works Ill post a photo of that too.

Hey Everyone! Good to see you all again! Back at it with the XF and having fun.   Hope I've got the right thread (forums not being my strong suit ha!)   Anyone know where I can get a fuel sender for this unit or has anyone brought an equivalent/universal that would fit?   I cleaned up my old one, did the dance with making sure it worked but stuffed if I cant find anyone selling another.   Please and thank you as always, I've learnt so much from all of you.

Well its been a while but I have good news. With the seat I just zip tied the springs back together and shes good as new, Im keeping the ea seat untill I get done with the roadworthy but then Ill switch back to the xf seat. Took it to the mechanics today and all he knocked it back on was some bushings an oil leak on the fuel pump and the exhaust so I ripped the exhaust out of an xg that was in a car graveyard near me and turns out apart from needing to die grind out the holes on the cat pipe it bolts right up (looks better too) so that was a success too! Ill get the bushings done tommorrow and hopefully thursday Ill be able to post a photo with plates.

ok thank u

Don't think the stator is supposed to turn freely in both directions.   https://www.youtube.com/shorts/-JWQ7sx0HsQ   https://www.youtube.com/shorts/pqmpbsFpQPk  

We haven't had any made for a long time. If you are lucky, SPArKy_Dave might have one left but I think they might have gone a while back.

TCI Saturday Night Special -  1600-1800rpm Only when the car is on the ground but while off the ground it changes through all the gears fine.   Hose not long enough.

Is it maybe a really high rpm stall converter? Lack of 3rd, could be a sticking actuator in the valve body, or a sticking governor in the extension housing.   Can you monitor line pressures, whilst driving it?

So found one problem, don't know how I did it but I managed to break the vacuum hose going from the steel tube to the modulator while installing the transmission. Didn't expect that. So fixed that problem, tested line pressure @ idle 175psi - reverse, 112 - 1st & 2nd and 92 - 94 for drive and neutral. While on stands, car changed gears properly in auto and manually, so I thought "great problem solved" However, when on the ground the lack of power is still there when reversing and driving down the road, getting 2000rpm @40kph. Changing gears manually was getting 1st and 2nd but no 3rd. Put the car up on stands again and the gears change normally as before.   So I'm at a loss here, could the new TCI convertor be faulty? or there is there something else to look for.
