too much tranny fluid?

[Ecomoda]

1989 240 DL auto.

Can any damage occur from having 1 quart too much transmission fluid in there? I'm not sure if it is low or not and I don know what would happenn if I over fill by just that one quart.

Cheers,
Hector

You might get "foaming" with too much transmission fluid. Foam does not compress like liquid and will make the transmission feel like it's slipping. I just bought a '87 760Ti "bad transmission" for $200 (hehehe). Took 1.5 quarts out of the overfull trans, freed up the kickdown cable and it shifts just fine now.

Similar story: Just bought an '85 245DL for $50. Some holes in the floor, but runs like a dream.
