Don't drive it! Have it towed to a garage that can flush the system, replace the radiator and hope that the transmission is not damaged.
not always, but most times, yes. it will ruin the trans fluid pump.
When coolant and or water gets introduced to an automatic transmission. It can and will cause failure. The material "clutches and bands" use as friction are attached by a water soluble glue. The glue dissolves and the transmission will no longer go into gear. It may happen fast are slowly over time.
Where is it leaking from? Could be front or rear seal or coolant lines Did you change gasket when you changed fluid?

Probably the thermostat is sticking.
To replace the AT coolant hose on a 1999 Jaguar XJ8, first, ensure the engine is cool and disconnect the negative battery terminal. Drain the transmission fluid and coolant, then locate the AT coolant hose, which runs from the transmission to the radiator. Loosen the clamps and carefully remove the old hose, then replace it with the new one and secure it with the clamps. Refill the transmission and coolant systems with the appropriate fluids, and reconnect the battery terminal before starting the engine to check for leaks.
First undo them at the radiator, then follow them to the transmission and remove there. After fitting new ones,check for leaks then fill trans fluid to required level.
No. Transmission fluid lubricates the transmission. Coolant is used by the radiator to cool the engine.
Coolant should not be leaking from your transmission the only fluid in your transmission is transmission fluid. A faulty transmission seal can allow transmission fluid to leak out.
The coolant leaks out.
It leaks coolant.
Only if the sensor is malfunctioning.
