Need some suggestions on what the problem may be with shifting hesitation on my 87' 300E. There is a definate second to 3/4 of a second pause between every gear shift. Tranny oil does not smell burnt and is at the correct level. Looked for vacuum lines running to it, unless there something on the top. Read something earlier about a teflon part in the transmission that can be replaced for approx. $300. Help!

Spencer,

I am having a similar problem with my 86' 300E, except after that 3/4 second when the car does shift into gear, it makes a loud "clank" noise as if it is shifting into whichever particular gear. My fluid levels are also fine.

Is this a flex disc problem...?

Any ideas anyone???

Thanks,
Jerry

Jerry, I replaced the transmission filter and it fluid and it shifts just wonderful now. Note I said, I replaced the fluid and not flushed, as I had a very reputable transmission man tell me he has more vehicles come back with transmission failures after a flush rather than return to him after a change. Hope this helps, if you have a operaters disc/manual it has a very good description of the filter change and fluid drain (more than one spot to drain).

Also Jerry, yes I did replace the flex couplings on the driveshaft, fairly inexpensive and easy to spot, just slide under ther car and look for wear in the holes.

Spencer,

Thanks for info...

I have already had the complete trans. service done by MB 2K miles ago. That was a great improvement...

I have heard that there is a front AND rear flex disc, are both visible from underneath the car? How do I know which one?

Thanks!
Jerry

It will be evident when you get under your car to look. Mine was the front coupling, I could easily see the wear in the holes, as they were worn much too large for the bolts. Also simply by twisting the drive shaft back and forth you can phisically feel the loosness. Hope this helps.
