300SDL Hard Shifting only well cold
Greetings to all --- First Post Here..........
We are the proud new owners, or should I say 2nd owners, of a 1987 300SDL. Brief background - Summers only, 10k per year, garaged in the winters, original owner is 70. I've been working through some minor issues with quite a bit of success. Here's the tough one...... The tranny shifts hard during the first 5 to 10 miles, or so, of the day. After that things seem to smooth right out. I have had the transmission fluid and filter replaced - no difference. I have purposefully not gone after the actuator because of how it shifts when warm. I look forward to your additional questions and advice. Thank You Stephen

Welcome Stephen!
I feel your pain. As you probably know there is 3 days worth of reading in the search feature using "shifting" or "transmission". Just a couple of the ground questions. Have you checked for vacum leaks? Do you have a Miti-Vac or similar tool? Oh Your are going to love this car

Probably a vac leak, isolate all the internals by removing the feed line going to the dash and plugging it at the vac side. Test drive the car and see if it shifts the same. If that fixes it then you have some work to do under the dash.
Old vacuum pods (piston actuators) used to switch air flow flaps tend to leak when the rubber diaphragms crack. Also, you should verify or have someone experienced with this engine verify that you have the upgraded vacuum pump, that is an invitation for a disaster if it fails.

Thanks!!!!!!!!!
Mighty-Vac is on the list for sure. Thanks for the idea of seperating the dash on the Vacuum system. Stephen

What's the issue with the vacuum pump? I have an '87 300SDL that shifts fine. The mileage is only about 76000. Should I be changing the vac. pump on the front of the engine for some reason?
