My latest 1991 350SD shifts perfectly, but is a bit slow to go into reverse. There’s maybe a second delay. Going into the forward gears is instantaneous. I suspect that some piston seal is old and worn or shrunk/leaky.
I’ve never used a high mileage ATF, even in my much older MB cars. My understanding is that the valvoline maxlife atf is the gold standard for quality high mileage ATF. However, I also understand it’s on the low end of the viscosity range, so it can cover the LV type ATF/Dex VI.
I’m curious for recommendations on what would be the best bet for a standard viscosity Dex III/DM type ATF. Yeah I know all about how they shear down, even the Dex IIIH types. That’s ok. Mine won’t get there.
Is there one that is a better bet? Or do I just run either maxlife, or the Walmart brand high mileage version?
Thanks!
