Rough Idle

any opinions on whether I should drain the case and then put a quart of so in and re-drain in an attempt to get any "extra crud" out of the tranny?

I suppose you could. Unlike an automatic, there really isn't any passages or a torque converter to trap fluid in it. The fill plug is right above the drain plug. So, I'm not sure how much benefit would be realized.

I bought this truck for my son 20+ years ago when he was headed to college. About a year ago, I was literally popping open my computer to take a look at craigslist and truck trader to see if I could find something to haul shit around and have something to play with - and he texted me from up in the Bay Area (I'm in LA) and said " Hey Dad, this truck just sits out in front of my house and I almost never drive it - do you want it back? Pretty good boy, right?

All of that to say, I don't have the maintenance records on it, but I would venture to say that that fluid has NOT been replaced recently. I am confident of my abilities to drop it and fix whatever is needed - but swapping out the fluid sounds like GREAT place to start.

I will do that and keep you posted

Other than an annoying and shitty experience with a Harbor Freight transfer pump that didn't pump, the transmission fluid change went fine...used Castrol Mercon V (is that pronounced "vee" or "5" ?) There were only minor shavings on the drain plug magnet.

I would say that 80 to 85% of the shifting issues were solved. I drove it down to Santa Monica and back through ugly traffic....so I essentially rowed my through traffic using the gear shift - previously it did not like the first to second and back to first transitions.....I probably didthat 100 times today and it was pretty smooth.

I don't have any experience with the truck except for the last 10K miles......the shifting isn't exactly silky.....but is it pretty amazing for 202,0000 miles.

Draining a manual transmission will improve its performance ?

Having the correct level of fresh proper lubricant works wonders sometimes for shift feel. I know if fixed a couple by doing just that.
