Thread: Discovery II TD5 Automatic gearbox

I got the sensor off the cooler through the drivers side access panel this afternoon. No gunk or build up around it. Do these play up at all?

Local mechanic quoted me $100 for a new sensor. I might be better off putting a temp gauge on instead to see exactly what its doing.

New Q's

Whats the best/easiest to install gearbox temp gauge?

Does anyone know where I can pick up a reconditioned gearbox at a reasonable price if it is the gearbox?

Hi mate I can see your new this section is for emergency break downs only so I will move your thread to the techincal section your questions will be answered in there

Hi there

A reconditioned auto is a gamble from an automatic reconditioner. I personally have just ordered a factory rebuild from zf automatics in Sydney. The cost is about $3200 change over. It comes with a new torque convertor and 50,000 klm nation wide warranty.

First of all I would be making sure your trans is doing what the sensor says its doing. You could buy an engine watchdog for $150 off ebay and bolt it to the trans instead of the cooling system.

Regards.
Michael.

Thanks Michael,

What did they sting you for the box?

Have you got the contact details for ZF autos?

I have just ordered a twin sensor watchdog. Has anyone fitted one of these and where did they attach the sensors?

Mine is fitted with a hoseclamp to the tube that carries the ATF from the torque converter to the ATF cooler(s).D2, td5, extra cooler fitted.
Been there for years, towing . On lock up it sits at 56 deg, in city traffic or normal hills around 86 deg, changes very quick.The hottest it has ever shown was towing about 2.5 tons on the Great Ocean Road on a 43 deg. day.

Thanks heaps mate, that is all very useful information.

Ashcrofts in the UK have beefed up units, shipped costs are around $5000- incl new TC.

The stock cooler is pretty good, never had an issue with it but the fittings are a nightmare. Either way with the sensor you'll need to replace it as if it's just faulty it'll keep logging faults and may limp mode it and show the light even with the new unit. Maybe find a known working 2nd hand one to swap over to try. If the autos stuffed then it'd stuffed, won't do much more to it by testing the sender.

Also what fluid are you running?

When I had the auto flushed and serviced, the mechanic said the fluid looked good and there were no codes stored. Is this possible if the light has been coming on?

Took it for a drive today and light came on after fueling up. I put my hand on the sensor and it was hot but not too hot to touch. The second cooler at the front was A LOT cooler. It makes me wonder whether I have a blockage on the factory cooler or the pump isn't working as it should.
