Gary,
I was thinking about that too.
There are people who swear by Dextron III and have never had a problem and then there are those people who
Say that they had problems with Dex III that vanished when they switched to MB Trannie fluid.
Consider also that an automatic from an 86 is not the same internally as an automatic from a 91.
I also would like to know the differences in lubricity, viscosity, temperature expansion and whatever other specs
Pertain to these fluids.
I have a 91. I switched to Dex III at 130,000 miles and I didnt notice any performance difference.
I also dont drain the torque converter when changing trannie fluid.
In every trannie fluid change that I have done on many vehicles, GM, Ford, to foreign, draining the torque converter has always seemed to lead to problems for me. I think that the bearings and seals in the torque converter dont get lubricated properly for too long a time when the converter gets drained. The torque converter also acts as the only oil pump in the trannie. If it aint full and pumping properly, there could be a lot of metal on metal wear until it fills properly and all of the air bleeds out.
But hey, Im only guessing.
