I have had my 84 300d for a month or two, but only now am getting around to working on its problems. Two such problems were (of course) a leaky vacuum system and (probably related) a hard 1-2 shift and a very quick 2-3 shift (meaning it stayed in 2nd for only a few seconds before going into 3rd).
So in digging through my vacuum system I noticed that the line to the transmission was plugged with a bb. I have heard of plugging the EGR that way, but never the line to the trans. I replaced all the rubber hose connections in the trans/vacuum system (basically everything in
this diagram) and replaced the plugged up 3-way connector with a new one. there are still some leaks in the 3/2 valves on top of the valve cover even after replacing all the hoses, but it's ok for now.
Anyway, the transmission now shifts much much better. The 1-2 shift is very soft and it stays in 2nd for as long as I think it should before going to 3rd.
Have any of you ever heard of plugging the line to the transmission? I dont want to trade one problem for another. Maybe there is some reason why that bb was there. I bought this car from a little dealer who couldn't tell me anything about it's history.
Also, not related, but I might as well ask. Does anyone have a hint for getting the pressure line onto the banjo bolt nipple. My pressure line was split right next to the nipple so I removed the bolt, and cleaned it out, but for the life of me I can't get the damn line to go more than a little way onto the nipple. The line is really hard and doesn't want to budge much. Am I just a wimp?
Thanks.
