CEL on 1995 E320

[kranje]

Hello.
CEL came on today, pushed the built in button it blinked 26 times.
The codes that i have says (Upshift delay faulty).
Can someone tell what that means?
I also checked pin #8 and #14 whith the code reader i built my self and no faults. The car has the 16 pin connector and 149k mi.
I replaced the engine wire harness last Fall that i bought from Fastlane from Phil.
Any advise is appreciated.
thanks.
