At oil overheating

[ElleBritton]

Hi, our 1997 land cruiser struggles to tow our horse. The AT oil light comes on and it loses drive especially uphill. Has anyone got experience with fixing this?

what colour is the fluid is it at the correct level ? What's the mileage ? Has it has a fluid and filter change in its life ?

Agree..^^^...could be the ATF is well past its best...check the ATF level...if it's black and has a burnt odour about it then it's ready for change.

Fluid like golden honey over the full mark but it does smell

ATF is usually cherry red in colour, i think you have checked the oil dipstick

 

Just to make 100% sure it's definitely an automatic ?

[ElleBritton]

Yes, definitely automatic - for towing is it best to have overdrive off?
