OK, so I now have two vehicles with this exact same behavior so its time to figure out what is going on. Tranny's are a weak point in my knowledge base so hopefully someone out there can help!
Both with a TH400 and a TH350 I'm having mass tranny fluid leakage. It ONLY happens after the car has sat about three days. I'm guessing what is happening is the tranny fluid is draining from the torque convertor, back into the transmission, making it overflow and its coming out the area around the dipstick tube. My question is WHY? Is there something failing in the torque convertors themselves or is there a mechanism in the tranny that keeps the fluid from backwashing into the trannies? THIS IS REALLY FRUSTRATING! No other noticable behavior as far as the trannys working - they appear to work fine as long as the fluid is in em!
Thanks!
