1983 300d Slow initial acceleration

Kent,

We just moved from Seattle to Colorado. 6200+ altitude. My 1983 300d accelerates very slowly from a stop, but once it is going about 15-20mph, it seems to perform just fine and cruises at highway speed very well. It has been a little slow to start and once and a while idles rough at the start. On my trip here, on some mountain passes, I had it to the floor, but it still could go 70-80mph up the mountain.

So, what would be the order of steps you would recommend to improve this situation? I just got it and have not purged, adjusted valves, or anything yet.

1986 300sdl Transmission problems

HI, Ive got a 1986 300sdl that I have fixed some vaccum lines on and changed transmission fluid in. Transmission shifts perfectly in all gears when cold but after driving awhile it gets stuck in either 2nd or 3rd gear. Most of the time shifting it back into N and back to drive will get it to upshift back to 4th. Would like to know what to look at and how to test. I have 5in vaccum at transmission at an idle. Any help Please and thanks.

1979 300SD windows and interior

Kent:

Just purchased a 1979 300SD with a great engine and body, but a trashed interior. Windows are not moving, switches for windows have been removed and just dangling (someone was obviously trying to diagnose the problem).

I have ordered your interior manuals about dashboards, etc. However, where can I find good replacement parts. Suggestions for sites? Also, how about exterior parts (i.e. like trim, etc.). Any suggestions on where to find those types of parts.

Also, do you have any guidance on troubleshooting the 116 windows?
