auto wont engage reverse

[Wornoutwoolclasser]

my 2004 patrol 4.8 petrol auto is slow to engage reverse. can take a few minutes. When it does engage it runs perfectly, just takes so long. Seems like a wire or switch or solenoid. Any hints

Any loose wires at the tcu in the passenger side kick panel?

when did you last have the Auto serviced???

Slow to engage sounds more like a hydraulic issue.

Thanks for the reply Mike02Ti
I jiggled all the wires like you suggested to no avail. It seemed like a good idea at the time. Alas
I took it to GV Autos who said it had coolant in the transmission.
I put a new radiator in it and i'll refill the trans after lunch
Think of me then
Cheers

Good question threedogs.
I have had it for 2 years and never had it serviced.
I took it to GV Autos who said it had coolant in the transmission.
Not good.

Thanks for the reply Turtle_au
Your diagnosis was close. Just not the hydraulic issue I was hoping for
A new radiator and fresh oil might fix it.
I'll find out this arfternoon

I have heard of a few 3 Litre Di Autos with the same Coolant in the Trans Fluid problem when the radiator gives up internally, and in most cases, the coolant kills the Auto.

I hope yours will be OK ..... if the plan is to keep the truck for a long time, it may be best to add a separate trans. cooler to keep the fluids totally separate, to prevent it happening again.

Thanks happygu.
I thought of that and decided that the radiator was probably well worn and a new one was $350.00. It was an easy fit, saved time and I could try it today.
New radiator, new coolant, new oil, same old problem. Auto knackered. Ah well

So the filter accessed by taking the bottom sump tray off the auto was changed out as well?

EDIT, for futiure reference, the transmission runs a strainer not a filter.
