[W126 Coupe] Transmission Problems with upshifting

[Mark Reimers]

The car has 105000 mile and no I did not check the kick down switch. I
will in the morning. What can I use to flush the gunk from the valve
body?

Did anyone check to see if the kick down switch is stuck?

I'd unplug it just to be sure.  Also might check the linkage make sure
it hasn't slipped Way out of adjustment.

Typically when I see mod's fail you still have all your forward gears.

Could also be some gunk has made its way into the valve body.

How many miles on the car?

Hi all,

 

3 days ago I'm driving my 91 560 SEC and everything is great. I get on
the freeway and punch it to get to speed. The car shifts to second and
stays there. Checked the fluid level and it was low so I put some in.
Problem remains. Took the car into a local tranny shop and had them
replace the fluid and filter including draining the torque converter.
Problem remains. I've got reverse, 1st and 2nd and nothing else. Did
some searching in the archives and concluded it might be the modulator.

 

Any ideas?
