You replace the radiator
Some have an internal transmission cooler & extra small internal radiator for that purpose.
This is a sealed transmission. It does not have a dip stick. Read the manual. sometimes that sealed transmission leaks by way of the radiator
Check your transmission fluid levels. Look around for leaks...you'll see a reddish fluid around the drive axle on your transmission or around the radiator.
The coolant leaks out.
on the ground, if it tranny leaks
repair the leak
You've probably got either a bad head gasket of a cracked head.That's the only place where the oil and coolant come in close contact. It may be transmission fluid if you have an automatic transmission - check your trans fluid level, and check for milky looking appearance to the trans fluid. The transmission cooler is integrated into the radiator and leaks can develop between the two.
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.
The fluid level in a transmission will not change unless it leaks.
lack of care and maintenance in the radiator dept.....how about checking your radiator fluid? checking the radiator itself for leaks, and replacing your thermostat. if this does not work then the problem could be lack of changing the oil....or burning of your transmission check your oil and tranny fluid.....flush the transmission....also if you tow stuff with your tracker you could easily burn out your transmission and that could cause the vehicle to over heat as well.
Probably a radiator leak or a split radiator hose.Check coolant levels in the radiator.
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.
