If you mean does the Transmission Fluid level rise, the usual problem is a leak in the trans cooler built in to the radiator. Depending on engine temperature fluid will transfer back and forth between the radiator fluid and the auto trans fluid changing the level and color of both.
Because there are lines running from the radiator to the tranny, this lets the fluid flow through and be cooled so that it does not over heat in the tranny and cause damage to your bands inside your tranny.
NO.
It can over time, it is not meant to be a lubricant.
there is no radiator cap only an over flow cap on the pass.side straight up from the pass.wheel
Transmission fluid. Many cars have a transmission cooler built into the radiator to cool the transmission fluid. Sometimes there is an internal rupture in the system spilling transmission fluid into the radiator thus mixing with the coolant.
doesen't have one. Have to do everything from the over flow.
The 1999 Ford Taurus does not have a radiator cap. Coolant is added by using the over flow bottle instead of a radiator cap.
It might be clogged, thus not allowing enough flow It means that the excess coolant is going where it is supposed to. The coolant expands when hot and goes to the over flow reservoir.
There is not a raditor cap. Only the cap on the over flow bottle.
possible hole in hose
The plow blocks the flow of air to the radiator for cooling.
CHECK YOUR RADIATOR CAP MAKE SURE IT ISNT BAD OR HAS A BAD SEAL MAKE SURE OR MAKE SURE ITS ON OR YOU MIGHT NEED A THERMASTAT
