If engine speed drops when you put the shift lever in manual low, or manual second, and take your foot off the gas...you have no engine braking.
I don't know why. Diesels maybe have engine braking removed from the ECM/valve body for some reason? No idea.
Now I'm gonna have to drive my '97 K2500 tomorrow, and throw the shift lever into the manual ranges to see what happens.
GM always disengages the converter when the throttle is closed/deceleration. Truthfully, I don't know how the converter clutch would react to that load. Might be fine.
I am thinking of putting a manual switch into the wire harness of my '88 K1500 700R-4; my converter clutch disengages above 72--75 mph; and I'd really like to have it engaged at highway speed.
