V6 pressure switch ATF

[xt600]

Does anyone know where I can get a new pressure switch, mine has started to leak fluid

[teenmal]

Is the item on the off side of the box.?

[xt600]

Yes, it's at the end close to the prop shaft. Assume it's a pressure switch, and it's leaking a little fluid...

[teenmal]

It sounds like the speed sensor, it should be held in by a set screw/bolt , probably needs an O ring, or check it for play.

It's leaking out around the wires so I think the leak must be internal. Are they easy enough to get hold of and replace?

Take that as a 'no' then!

Possibly a 'Don't know'.

Is it that speed sensor your talking about? There isn't any form of pressure switch on the auto transmission .
Have you cleaned it up and has the oil returned ?
Is it part 21-5H2 lower right corner ? If so that is the speed sensor.

[teenmal]

If the item is on the o/s of the box its the speed sensor, 17-400 on the drawing.

[xt600]

Yes, thanks, appears to be the speed sensor. I presume the petrol and diesel models are the same. Anyone know where I can get a new one, or do I need to visit the local scrappy for a second hand one?

[teenmal]

If it is the speed sensor drive .. the part number BV8217400..your local Mazda dealer is your best bet. It is not the same as the 2000/2.5td .


You could also try gear box repair centre.

Thanks for your replies, due to the rip off prices of new parts (and some used!) I think I'll wait until one becomes available second hand

Just remember to have it fixed for the next MOTT, its a fail otherwise .

It's only seeping, not dripping out so won't be a problem for the mot
