"Aggressive" transmission shifting
I have a '84 500SEL, which recently went through a "restoration" of sorts. During the process, the transmission was removed to replace a seal on the engine. I had the old transmission fluid replaced with synthetic fluid, and everything was put back together.
Now when I drive the car (around town, for example) the transmission keeps it in second after I'm done accelerating instead of upshifting like it used to. Only after I remove my foot completely from the accelerator will it even think of upshifting to third. If I'm really accelerating (on the freeway), everything works normal. I'm sure the mechanic will take a look at it for me, but this is an inconvience. My question is: could there be any "rigging" or adjustment that I could perform to remedy this problem -- or is the problem most likely inside the transmission itself? Seems to me that the transmission is acting like I'm trying to go fast, even when I'm not.

Make sure the bowden cable is adjusted right and moves freely. I've seen one pinched between the block and bellhousing once and it shifted weird, off the governor. (very late and very hard)

I bet Joe is right on. The bowden cable can also be referred to as the "control pressure cable". If the transmission was removed, then the cable had to be removed, and would likely need adjustment when re-installed.

Ok, 103 powered, look under the air cleaner behind it, black cable body, white "screw" adjuster, ball end on the linkage.
104 powered, 2 types, upshift delay type, green with a white end and a red boot under the intake more or less foward of the EA, non upshift delay, same general location, just a black body, green and and posibly a red boot. Both have ball ends on them. Joe

patkinson,
E-mail me tvpierce@hotmail.com and I'll send you the pdf file detailing the adjustment. It was originally sent to me by "haasman" -- a member of this forum. If you're out there haasman, thanks for sharing the knowledge. Jeff Pierce

You are welcome! That is what is great about this forum; everyone helping each other out.
Regarding the "Agressive" shifting, please be sure to check out the vacuum line, connections and the vacuum modulator on the transmission. Haasman
