Well you learn something new every day!

Thank you very much for those links, that is GOLD for a guy troubleshooting the system or learning its theory.

I am really amazed how SLOW the car is off the line with a 2nd gear start. Of course, the most basics still need to be addressed like the tune of the motor.

I still have a bad solenoid so hoping that will at least give me a passing gear kick down when requested with the pedal.

Make sure that the banjo bolt that connects the ALDA line to the intake manifold is clean and clear, the valves are adjusted, and that the you are getting full travel on the accelerator linkage from the accelerator pedal at the IP. Also new fuel filters are a must.

Will do. I have not messed with an ALDA in a few years but probably like riding a bike.

Now I am off to the dealer to see if the Unicorn kick down solenoid still exists.

If not I'd bet more than a few members have a spare transmission sitting around that would sell you a solenoid.

Something is not right though.

2nd gear start is working to get me around.. but I was leaving a friends steep driveway today and car would not even move an inch unless I shifted into low to get up the incline.

I keep reading on other forums where people replaced the solenoid and repaired the relay in the passenger footwell and 1st gear starts returned.

I need to just stop being lazy and read the manual and see if it has anything on it.

1st gear was meant for steep hill starts, or when the car was loaded down. You should be able to engage it with the accelerator using the kickdown switch.

2nd Gear Start

I also have a 1979 300sd w116, and it shifts into 1st gear when you release the brake pedal. With the engine off and key on in a quiet place, you can hear both the relay and the solenoid actuate when press and release the brake pedal. I have also read (maybe the FSM, I cant remember) it was due to the brake creep previously described. If you put the shifter in the "1" position, it would stay in 1st all the time, and it did cause an increased brake pedal effort. Just another data point. Maybe the 1979 300D and 240D were different because they have the lower power NA engine, where the 116 had the turbo. All I know is I released the brake, it dropped into 1st and I leapt off the line. I imagine there are a lot of w116 300sd driving around with either an inoperable solenoid or relay.

Another forum member is shipping me a Solenoid for me to toss in and see if it is the issue.

I re-soldered the relay box as it had a burned out lead ( apparently very common).

I will report back my findings if this is the fix.

I realize this has been re-hased over and over but I also think that w116 info is much more scarce as not many were produced compared to other series.

And even fewer are still on the road, mostly due to rust and the god awful climate control system.

Just to update this thread.

I received a used solenoid from a forum member here and bench tested it. Worked well.

Installed into transmission and I now have 1st gear starts back. Very thrilled about that.

Now I need to tackle the kick down switch and part throttle downshift issue.
