Nothing like a day off to bond with the Benz
Greetings Guys,

Among other things, seeing as the day was somewhat warm and I really needed to adjust my valves anyway. I tinkered with the throttle downshift cable. I found that screwing out the plastic threaded cable end causes the tranny to delay it's shift points to some degree as well as downshift on uphill grades where rpms are needed to maintain a preset speed. Yes, it takes some tinkering and readjusting to get it to shift right, and also feel right, but I think I have found a happy medium. I also did a bad thing and plugged the vacuum line going to the EGR valve. Don't know if there will be any benefit to this, but we'll see.

Charles
