Wow, the turbo/ALDA works now, but now I need a little trans advice - PeachParts Mercedes-Benz Forum

I did a little expiriementing today, and yanked the overboost protector off. Wow, what a difference the proper amount of fuel makes!

I adjusted the trans for use with the power I was getting before, without the turbo. I had just ran a vacuum line directly from the vacuum source to the trans and adjusted it accordingly, it was working fine. Now that I have all this extra power, I hooked up the vacuum amp, and the vacuum control valve back up according to the diagrams. Now, 2nd and 3rd won't shift completely into gear unless I am barley on the throttle. They will wear into the gear, much like riding a clutch.

After doing some searching on the forum here, I unplugged the vacuum from the trans and tried...same problem. Does this sound like the K1 spring problem, or is it just that there is too much trans fluid in there? I am going to get some of it drained tomorrow morning, but if I am going to need the springs, I would like to get the order in as soon as possible.

Sounds like too much vacuum.

I don't know much about the alda, but my tranny does exactly what you described. I'll be keeping an eye on this thread for some helpful advice.

I unhooked the vacuum line, and I can feel it thumping into gear, but it still slips all the way through it. the RPM stays the same, but I speed up.

NY300SD, The alda adds fuel to the cylinder as the boost increases. The overboost protector cuts the alda off when there is too much boost present. Mine was so old and clogged, it wasn't letting any boost get to the alda at all...that's all I fixed. Now I have this trans problem.
