Hello,
Last week my 1990 560-SEL would not upshift into gears 3 and 4. Reverse is fine, N is fine P is fine. Trans is quiet. Never a problem at all before. Had this beautiful car for 2 years. Fluid level is fine. Vac is hooked up fine to Modulator. 208K miles on her. Disconnected kick down on trans, still nothing. I am stumped. Really hope it is not the trans needing replacement. Can they go that fast without warning? Its still very quiet, just wont upshift, stays in 2nd gear always. So fustrating. Any had this before in there 126? Wondering if its worth fixing if it needs a news trans too? . . . thanks all for your help. Could it be the vacuum modulator?
This breaks my heart and wallet too . . .
