To Anyone Who Can Help:

I'm having problems with my 86' 300E. It has about 150,000 miles. For the past month or so I've been having transmission problems. It would spontaneously downshift to 3rd, 2nd and sometimes neutral! At first I thought it might be the automatic transmission filter and fluid so I changed them.

Everything seemed fine, then the problem occured again a few weeks later. This time I notice the problem occurs when the automatic transmission oil has been warmed up. For example it'll shift fine for the first 5 minutes of driving, but after the engine and transmission has been warmed up, the spontanous downshifting occurs again. But this time won't upshift either.

To summarize my problem...now when the engine's warm, it'll downshift spontaneously and won't upshift anymore. What's going on? Any advice would be greatly appreciated.

Sincerely,
