P38 Range Rover 4HP24 connector leak Fix

I fix transmission leak by removing 30mm Nut on electrical connector to the 4HP24. I emptied the fluid from Sump. (5 litres or more). Then cleaned thread on the connector with brake cleaner. I observe no fluid coming from the thread area. I then apply Hi-temp sealant to thread and nut.
I waited 2 days then reconnected the loom to the connector and drove vehicle for a month. The leak is no more!
I should remove valve body, replacing o-ring from inside. However this is a safe solution. Sealant is outside and not going to enter sump. It'd not be safe to put sealant inside the connector (for example where the O-ring is). You don't want broken down sealant in the fluid mix of sump. For this reason I decided to try the job I did. It has worked for me.
This won't work if you have a leak coming in through the actual wires on this connector (some have had this). In that case a new inner loom piece will be needed and are available still.

Good repair. My problem was that it was leaking at the pins, preventing the car to start at times

@@kalani1987 oh bother! with valve body off did you change anything else for example the o ring? or just the wiring section?

[@kalani1987]

@ESlashP well I was told I needed a new valve body altogether. I haven't done anything yet as I'm contemplating how to fix. I have to unplug the connector now and then to prevent it from soaking too much to prevent the car from starting

So you need to remove the valve body to get to the loom and work out a way to fill the wires going thru the connector from the inside to outside. Id probably fill the area behind the wires at that stage but it would be something that cannot break down, as this silicone like I used would not last long immersed in trans fluid. It would end up in little pieces all thru the gearbox and destroy things quickly. Perhaps new loom and valve body u less a filler that wont break down can be sourced, to stop your wires getting fluid on them. Let me know what you did to solve that one. Im sure mine will start leaking there eventually too.
