crauch Posted June 28, 2005 Share Posted June 28, 2005 My 99 forester overheated today. It started shifting crazy and then it over heated I found transimission fluid in the radiator. I am sure that the water mixed in the tranny. I have never had a problem like this. Does anyone know what needs to be done next.? Quote Link to comment Share on other sites More sharing options...
Strakes Posted June 28, 2005 Share Posted June 28, 2005 There is a transmission fluid cooler built into your radiator with two little lines attached to the bottom driver's side of the radiator. The top little line flows transmission fluid to the radiator/cooler and the bottom goes back to the transmission. I bet that somehow that this is what busted and has leaked transmission fluid into your radiator and possibly sucked coolant into your transmission. Replace the radiator and flush out the cooling system and transmission and fill both up to the appropriate levels and then see if you've got any transmission problems. Hopefully the problem was caught early and didn't cause transmission damage. Also, you may want to replace your thermostat while you're at it. To flush out the transmission, take top little hose to the built in transmission cooler in your radiator and put it in a large container, and put the bottom little hose into a large container of fresh transmission fluid (about 10 quarts). Start the car in park and the transmission should empty most of the contaminated fluid out into the bucket and suck the fresh transmission fluid in. When the fresh fluid starts coming out of the top hose, turn off the car and reconnect the hoses and check the fluid level after starting it again. Good luck!
