Ok here is my story, my 97 Dodge Avenger with 150k miles is starting to mess up. I know my tramission fluid is leaking, but not sure if this is my problem. Here is my problem. When I'm driving, along and any speed really and slow down just a tad sometimes, my transmissions slipps and I end up with high rpm because its like the car is in neutral but its still in drive. I then have to accelrate to help the car get over 4rpm and that sometimes fixes the problem or it will click over itself sometimes.
But here is the kicker, if I put tranny fluid in it wont do this for a couple of days?

WTF???
Any help would be greatly appreciated.
Thanks
