Hello I am new to the Forum. Please take a short breath.
I have a 2001 Disco II with 49K miles bought used. Not having the service records, I decided to change all the fluids pronto. The engine Oil seems quite dark and seemed to be at about or past its intended limit of use. I replaced it with AMSOIL Synthetic 20/50 (which I have used in my BMW M5) a good oil with a good record…just expensive at 7.50 a quart. I changed my tranny fluid draining it into a basin of 7.5 quarts capacity. The basin was full almost full to the brim with the drained fluid. My estimate was that it was at least 7 quarts. Now common sense tells me that I have to replace at least the volume of fluid that I removed. I followed the procedure to replace the fluid, using “Penzoil Dexron III Mercon ATF”. Try as I might however I did not seem able to replace all the “removed” ATF fluid. I followed the procedure running the truck thru the gears a number of times and by my measurement was only able to replace what seems to be about 5.7 quarts (measuring what came out of the “Penzoil” bottles). I even turned the Vehicle around to make certain it was on level ground…..still fluid continued to drain out the refill hole as I try to pump in more. I finally gave up. Full is full. I have to assume my measure was not exacting and that the tranny was at its full capacity. Since that maintenance the truck has been driven 150 miles with no problem…..the one exception was that after hitting some bumpy highway construction the “TC” the “ABS” and the “Hill descent control(HDC) failure” simultaneously came on with 3 chimes. I pulled over after driving another 300 yards, shut off, waited 5 minutes, restarted, lights went away….so far so good.
Just curious as to if anyone else has had this experience. I also have a question relating to the use of synthetic ATF. I had actually purchased AMSOIL ATF synthetic with DEXRON III for the tranny, but after consulting with two local LAND ROVER “DeEYElers”, I was dissuaded from using it. They stated that ZF (the tranny manufacturer) was not keen on synthetics being used in the tranny. Would someone please give me the scoop on this? This is probably some of the best synthetics money can buy…but of course not being an hydraulics/chemical engineer, I don’t know what the issues are.
Regarding the rest of the fluid change; I will be replacing the existing Transfer Case and Differentials fluids with AMSOILS Synthetic Gear Lube, 80W/90 this week end. Does anyone see an issue with using this Fluid? I will then move on to the Coolant, Power Steering, Active Cornering and Brake fluid next. I have some ATE TYPE 200 brake fluid “extra long replacement intervals” DOT 4, out of Germany. The boiling point is 200 C (536 F). Is anyone familiar with or see a problem using this?
Can someone please fill me in on the type of fluid for the Active Cornering?
Thanks and sorry for the long post. Great Forum!
