A440F line pressure port thread size (1 Viewer)

[metro55]

Does anyone know what the thread size is for the line pressure port?
I'm looking at fitting an in cab pressure gauge.to my HJ61.
Sender units come with 1/8 NPT. Not sure if I will need an adapter.

My last transmission re-builder has stuffed the recon twice in 12 months
With this second fail he is now blaming on the TC he insisted that I sourced, but the converter builder is now blaming the
transmission builder because the kick -down cable was set with 4mm of slack his claim is that was causing low line pressure.
Wholesale automatics recommend 3mm tension. Yes I have one of their Valve Bodies.
Since the cable was adjusted to Wholesale's specs lockup if fine until the trans gets hot.(100c)
This happens very quickly once a caravan is on the back.
Lock up is not noticeable when hot and revs @ 100KPH are about 200rpm higher, then temps can climb to 120c

I am looking to test line pressures whilst towing, testing both cable adjustments to see if there is a difference.
Thanks for any help...

Hey mate, have you had any luck with this issue ? Cheers

I’d find another transmission guy

Ok fair enough man. Would you know where is the pressure port on the transmission? I'd like myself to connect a pressure sensor.
Thanks

After several months of getting the run around I finally have another shop that is helping me with this.
The fitting of the transmission pressure gauge helped diagnose a pump fault.
Line pressure is well below specs and therefore not enough pressure to maintain lock-up
TC over heats. We are now looking for a pump.
fitting the gauge was easy, port here: FJ62 A440F Trans Rebuild - https://forum.ih8mud.com/threads/fj62-a440f-trans-rebuild.678364/post-8277590
I fitted an 80 series pillar pod to house the gauge.
Having a 24v import mad it easy to wire up , just google Transmission Clutch Oil Pressure Gauge 24V with matching Sender . veethree gauges
you need two adapters.

My line pressure in drive was SUB 100psi and sub 150 in reverse @ stall speed.
I have a low stall 1500rpm TC

That's awesome mate, I reckon it is definitely a great essential tool of the same rank as any other fluid and gas pressure ! Well done man !
