Transmission could be adversly effected. Shifting problems can occur and worse case the transmission can be permantly damaged.
The whistling noise could be a belt but I don't know about the gear jumping. Something wrong with the transmission most likely. Teeth missing.
Mine is out of Freon.
Could be transmission bands are worn and require adjustment or replacement Try changing transmission fluid and filter
i belive it is but just check the model number on the tranny and make sure they match just incase im wrong yes so it the entire engine assembly
your transmission could be shot. if it will not shift at all, then you will need a new one.
it's probably the head gaskets.
No the transmission will not overheat, the wrong type of fluid could just ruin it the transmission. Same with also using too low or high amounts of fluid. That's why they recommend using the right type of transmission fluid.
You sometimes could get things wrong that's how it makes the question harmful
The cost of the repair of a transmission depends on the what is wrong with it. It could range from about $100 to several thousand if it needs to be replaced.
Could be anything from an engine management problem to the transmission failing
It could be a number of things going wrong. Try dropping the transmission pan and changing the transmission oil filter and transmission fluid.
