Degreased Engine - transmission shifts hard

I am the new owner of a 1990 300D 2.5 turbo. Against my friends advice, I decided to degrease the engine to see where diesel was leaking from.

I used the spray on type foam on the cold engine, and covered the alternator. I used the least amount of water possible from the garden hose.

After hosing it off, I started the engine and ran it around the neighborhood until it got nice and hot, but I noticed that the transmission is now shifting very hard through all the gears. It almost clunks into the higher gears.

Any ideas? Have I fouled something up?

you probably knocked a vacuum line loose. Go over your vac line connections

Thanks for the advice - you were right...

I knocked one loose when I was checking the air filter. All fixed!

Thanks again.
