Do I need a gearbox oil cooler?
Hi everyone, I'm thinking of using my MK1, 2 litre diesel auto to pull a caravan round Europe. Do I need to fit a gearbox oil cooler? Is there any way of monitoring gearbox temperature through the existing instrumentation. Am I worrying unnecessarily? As always any advice gratefully received. Jim

Hi Kev, thanks for your answer, I did know about the cooler in the radiator, but read recently that this might not be up to the job if towing for long periods with an automatic, particularly for long uphill sections. Has anyone had a problem with this when towing? Jim

If your radiator electric cooling fan is working on all speeds you should have nothing to worry about. Its speed will increase if the ECU detects that additional cooling is required (source: RAVE). Simon

Correction: Think on the Volvo with factory fitted tow bar and when a load is hitched up, there is a signal to the ECU to set off in lower gear range. Last edited by rustymotor; 25th February 2018 at 06:57.. |

I`ve towed several vans over the last 10 years with a diesel auto 75 tourer with some very near max weight and never had a problem.As said above just make sure the autobox oil is changed at regular intervals.

My cdti auto is putting out 160BHP and has covered 3,400 miles all over Europe with air temps in the thirty’s never had any problem with the box getting too hot it’s own cooler works fine. My van when fully loaded up is close to 1460kg the four passengers made up another 380 kg and probably 80kg of junk in the car. When towing I just stick the box in sports mode and the car pulls it along like it was not there. Best combination I have ever had my 75s combined over the passed 20 years have probably pulled over 280,000 miles with out a hitch. Pardon the pun. Sent from my iPad using Tapatalk |

There is a post HERE shows variations in transmission oil coolers from air blast to fluid item (19 ) if it helps. To my mind the air blast looks the best.

No smell at all from the gearbox or from any other part of the powertrain. It perhaps should be noted that I change my ATF every 60,000 miles and the crankcase oil filter every 20,000, I use Land Rover. Crankcase filters you can usually pick them up for a fiver. Sent from my iPad using Tapatalk |
