Trasmission started pouring out transmission fluid the other day. was pulling a small trailer with my HD... I crawled under and it is coming out in the rubber plug area. So what is the worst..and or any ideas. I had resently replace all the fluid and filter. Another questioin I have located a used EOD4 that was suposed to have been rebuilt 20k or so ago. and special requirement to pull the trans and to replace it in my truck. Or is the repair to the leaky trannny something to consider. Thanks
