On my 87 300D only when I have the kickdown switch fully engaged it will shift 1st to 2nd fine(4900rpm) then shift from second to third(4900rpm), then immediately back to second and shift into third at 5100rpm. It will then stay in third and shift fine into fourth. This is all with the pedal to the floor and never lifting my foot off the kickdown switch. It is doing it every time like this only when the kick down switch is engaged.

It shifts fine in all gears when the switch is not engaged. It shifts properly in all other ways.

I have replaced the klima kickdown relay, kickdown switch, and over voltage protection relay. The kickdown cable is just slightly tighter than nuetral and looser or tighter does not change this symptom.

Any ideas? B2 piston? K1 spring kit?

It does take a little longer to go into drive and reverse than normal but not that long. This trans does have 299K plus and is all original. The fluid and filter has been changed recently and the level is correct.

Thanks for your ideas and suggestions!
