84 300 Turbo Transmission Not Shifting

Just Picked Up The Car For A Song. Apparently Working Well - No Problems- When Parked 2 Yrs Ago. Ammazingly It Started And Drove Fine, But Wouldnt Advance Past 2nd Gear. We Topped The Fluid But No Change. I Fear That A New (used) Trany Is Going To Be Required - Anybody Got A Good One?

Cheers, Andrew

Parked for two years?

Use trans-x. It sounds like goo in your valve body. Time to then replace the fluid and filter.

Maybe some tundra got in there

I'm suprised nobody else has offered any advice.

Looking through the archives, there are two possibilities.

1) Leaky valve body in trany. Putting some Trans-x in may help with this.

2) The kickdown switch under the accelerator pedal may be stuck on or defective. Disconnect the switch and see if it helps.

I'm hoping my problem is #2.

My problem WAS #2.

You should disconnect the kickdown switch under the accelerator pedal and try again.

Thank you mplafleur. It was the kickdown switch. I just removed it and the transmission shifts fine! The car is a real pleasure to drive. I now realize that I have spent too many years bashing arround in my triple weber TR6 (summer car) and GM diesel pickup(winter beast) and never knew what is is like to ride in comfort.I use this old mercedes as a winter car now. Thinking of doing some biodiesel home brew.

Thanks for your advice

Andrew.

Hey,
Glad you got it sorted out.
Now I'm wondering what does this kickdown switch do?
Besides preventing the transmission from shifting past second gear!

If you are driving along on a two lane road, need to pass someone, and have limited broken while line distance to do it in... then putting the throttle pedal to the floor should ' kick' the transmission into a lower gear which will give you faster acceleration for the passing.
