My 1988 560SL kickdown works at around 20 MPH and also on…

Hi there: My...

Hi there: My 1988 560SL kickdown works at around 20 MPH and also on the freeway if I am under 52 MPH. When kicking down at 50MPH, car shifts down to 3rd gear and does not provide a lot of passing power. Also, above 52 MPH, kickdown does not work at all. Any ideas?

Mechanic's Assistant: How old is the transmission? Have you checked the brake switch?

Transmission has about 79,000 miles. Don't know what the brake switch is.

Mechanic's Assistant: Are you fixing your 560SL yourself? What have you tried so far?

Just had it worked on; they replaced the fuel pump relay and kickdown switch and insist that the kickdown is operating as it should. Perhaps that's just the way it works?

I don't know if they did. If this is the way it is supposed to operate, then it is fine. I just thought since the car is capable of doing 70 MPH in second gear, that the kickdown would be a bit more aggressive. After all, I can always shift down manually if I need to.

Yes sir , that is true,Yes i believe that is how it supposed to work .

the trans could be a little weak, i suggest a trans service and tune up if not been done and retest

You are very welcome :)
