Car did go in flood but not to deep trans was under water could it be wireing in back trans
Try resetting your ECM.
Probably a faulty sensor on transmission. Which is why its going into limp mode
Sounds like the car is going into limp mode which does not mean there is a tranny problem. Take it and have it hooked to a code reader, you will need to find a garage or something because the cheaper ones that are sold in your local automotive supply stores dont read the trans codes. Another option is to turn head lights on with the key NOT in the ignition and take the negative cable off the battery, then remove the positive cable, wait 10 to 15 minutes then turn head lughts OFF, recinnect the positive THEN the negative battery cables. This will reset the on board ECM.

my friend had one that did the same and he replaced throttle positioning sensor and it fixed it. but when you put a new battery in them they wont idle until you hold at steady low rpm for almost a minute because it has to relearn its position. so check your voltage meter and make sure it is around 13-14 volts when running and not on 12 while running because it could be too low of voltage for it and would be the same principle as disconnecting the battery because it takes 12 volts to keep computer on. hope I wasnt too confusing but I just want you to check your voltage for free before you buy electrical parts.
SOURCE: Cruise control stopped working
if the fuses are ok then i would say that there is a distruption between the cruise module vehicle speed sensor and the computer(ECM). unfortunately this is something only a qualified tech with diagnostic equipment can correct. i'm sure there are stored fault codes that the tech needs to check and reset. it's been my experience that oftyen times when this problem happens it has to do with the transmission control module which dictates how the engine and the transmission sync up to shift properly and your speed is measured through the transmission circuit thus the cruise control circuit is slaved to that.anymore questions feel free to contact me . just click my user tab on this site

If you want to know the where the water is coming from, water is entering from the passenger side front cowl. ( the vent below the windshield that sucks the air in for your a/c and heat) there is a recall where chevy installs a plate under the cowl and diverts water out. There is your answer.

SOURCE: Problem with 2006 Chevrolet Impala --Windshield washer fluid
Sounds like the fuse blew out again. Look at the wiring that goes to the washer fluid pump and check for any place where it might have rubbed against something causing it to short out. Fix this 'short' before you replace the fuse again or you will continue to have problems.
