Question:

Transmission leaking into radiator?

I have a 2001 Dodge Neon, and lately it seems as if everything is messing up And we are short on money. The radiator was leaking, so we put some stop leak in it, and it works, temporarily Now the transmission is leaking. The car slips in and out of gear The heater stopped working, and I could hear the water bubbling, but the car wasn‘t overheated. So I replaced the thermostat. Heater started working again. Then the next day heater stopped working and water is boiling again.Took it in for an estimate today, well my hubby did They said the radiator needs to be replaced, the transmission is leaking into it and that‘s causing the problems Does this sound right? And does that affect the thermostat? Its our only vehicle, so he said we can drive it, just to keep tranny fluid in it But as soon as we put fluid in it, its leaking out I will see a little puddle $250 estimate Just wanna know before we spend the money

Answer:

cheap fix: take the cooler lines off the radiator that come from the tranny. you need to plug/cap those holes. you now just need to connect the 2 cooler lines together. a decent auto parts store can get you what you need for $20 or less. you'll need to add tranny fluid as the water evaporates out. you should take it easy with the car.no towing or trips up hills until this is properly repairedbut it'll work a long time as a daily driver.
I have a Honda Sportrax 250 and I ride trails. I prefer trails to the track or desert because there's so much more to see and it's so beautiful, especially if you ride in the mountains. Hope I helped!
i ride everything dunes trails track and desert i have a kx 250 and stock suspension
sounds like you have A bad Radiator to me, there are Transmission lines that connect to the lower half of your Radiator to cool the Transmission fluid, hot fluid will cause the tranny to slip. Gotta flush the coolant system, after replacing the Radiator you should also service the tranny just my opinion
Absolutely the right answer from the mechanic. The transmission has a cooling line that goes to the radiator and back into the transmission again. The radiator has corroded (it is 11 years old and they usually have to be replaced after 10 years or so) and it is leaking into the transmission, replacing the fluid with water, which will ruin the transmission if you don't get the water out of it, especially if you live in a cold state where water freezes in the winter. Get the radiator changed, the transmission drained (and a new transmission filter installed) and you should be good to go, those are great little cars and will last a long long time outside of normal wear and tear like this
