I've been playing with the bowden cable and it is shifting better. There is still an issue with it shifting from 3 directly into 4 when i do a hard acceleration. If I drive very easily she seems to shift alot easier. Any more ideas?

I believe there is a kit available to stop the stacked shifts. Search on Superior shift kit.

I've never heard of that. I just checked it out and its not something I'm interested in. It looks like you have to actually go in the tranny or pull it to work on it and thats WAY beyond my capabilities. I'll just manually shift it if it gets that annoying to me. I didn't know if it was now a vacuum issue or modulator?

Yes, to help with old transmissions, sometimes you need to dig in.

I have her adjusted just about right. There is definitely an issue with the 3/4 shift. It shifts well from 1/2 and then when its time for 3 it jumps and goes right into 4. I'll probably start off in 3 all the time and then when its time just shift her into 4. If it wasn't a bear of a job I'd try the 3/4 shift kit, but I think its more headache than its worth.

After everything I've been going through I finally found out there was NO vacuum at all going to the Trans. The front of clip of the switchover valve was cracked. I somehow still had vacumm coming from inside the car though? She shifts smoother and I'll find out tonight when I take her to work if the 3/4 shift is better.

In the SD you have two vac systems. The vac that goes to the tranny is not the same as the one which runs your door locks; the pump for door locks is in the trunk. No connection between the two.

Maybe this is just a different line then. The pump in the trunk is disconnected. Can't figure out why it won't work still. The was no vacuum to the top of the valve cover or the trans,but one of the vacuum lines at full suction. It was one of the larger air lines like the ones to the ALDA.

Did you measure at the rubber connector with arrows pointing to it?

Make sure the rest of the system is connected.

Not bad, 12 inHg is ideal.

little round roller

FYI, in this picture I am moving the linkage so that all the slack is removed and any further I pull will move the pump throttle. With slack this gap will be a little bit bigger (which can be seen in the first photo).

When I got the car, that round bushing was halfway through that slot, and the transmission was shifting a bit later than it should. After making these adjustments, the car feels "correct".

Sorry if these pictures are too large, I am at work and have no software to resize!

How would one adjust that little round roller? When at rest (300SD '84) mine looks like the one in the second picture not the top picture, it's not fully seated in the crook of the slot. And I've felt that the shifting is a little late but nothing too crazy... Is the adjustment to the round roller made my tinkering with the throttle linkage assembly?

Thanks in advance folks
