Just had an additional auto transmission oil cooler fitted so auto oil should have longer life towing the three ton van.
The auto trans oil has been changed three times now and that's with 203K total 70k approx was with van on behind. This time we added Dr Trannys and an ATF supplement to the ZF Lifeguard oil.
In an earlier post, I wrote that I had an intermittent injector problem, I was wrong, it was just the auto oil needed changing and adding the Dr Trannys etc, car is once again real sweet to drive and it probably has the cleanest injectors, if not, it should be with all the cleaner I put in with each tankfull over the last few months
Thanks for info. Google does not show so will give them a call.
Do you know if there is a thermostat installed in your install or cooler ? or do you have a temp gauge to say what it is ?
With this cold weather (10-15C) and not towing would think the fluid would find it hard to get up to operating temp maybe unless on a long run.
Some coolers only let a few cores to have flow until oil temp rises and then the full cooler opens.
