The flood killed the tranny

Sometime last summer, my 190d2.5t was parked in a parking lot that flooded. I got to the car before it was completely submerged. The height of the water was probably close to the high side of the bumper.

Of course, when i opened the door, all the water flooded in. Surprisingly, the car started and I was able to drive away. I took the seats out and the carpet and dried all that out. The only thing inside that got fried was the kickdown switch. I also noticed that alternator was not charging so changed the voltage regulator (?..the white ceramic thing with the 2 magnets) and all was well (it was charging).

I thought all was well and I had acquired a minivan to drive around so i mothballed the 190 in the garage until this week. the motor was running rough so i diesel purged it (3 cans) and it is idling much better now.

So the problem was extreme sluggishness from a stop. I initially thought that the engine was the issue but now I think it is the tranny.

This was my test--
I wanted to see if the engine would rev freely and it does. It would rev to is max if i wanted it to. So why was the car so slow off the line?
The car will work fine in the morning (almost normal--it shifts by itself) but once it heats up the sluggishness returns. I experimented with manually shifting from 2 to 3 to D and down to downshift and it seems fine.

A second test was to rev the motor up then put it in D. the tranny did engage but damn it was slow.

However, from a standstill, a guy on a bike could pass me until i hit maybe 20 mph and i can put it in 2, then 3 then D to keep up with traffic.

So I have come to the conclusion that it is the tranny. It almost feels like it is starting at a high gear. In a manual drive car, it would be like starting in 3rd gear....it will get going but very very sluggish.

I bought some Dex3 atf and I plan to change the fluid this weekend but I am doubtful it will change anything even though the fluid in the tranny now looks perfectly normal and is at the right level. the fluid is not milky at all.

Is there something that sits outside the tranny that could have been damaged by the flood even if the water did not get into the fluid?

Have you checked to see if if the wheels spin freely? Maybe something with the brakes. Maybe something with the hubs/bearings.
