98' B4000 5-spd Tranny Fluid Replacement

[ndccpf1]

205,600 current miles and 75K miles since the last drain-fill on the 5-spd tranny. Drained this week and fluid was BLACK. pumped in just under 3 quarts of Mercon V. Immediately felt the difference as I shifted to pull back down the ramps. And quick drive around town proved the same. Nice and smooth shifting.

I'm pretty sure tranny and or t case fluid is something almost nobody ever checks or changes. Unless the rebuild it or replace it.
