hi I have a 1990 ram w150 and It was running great and all of a sudden it lost power. I was stepping on the gas and the truck was barely moving forward but it will go on reverse without a problem. I got it home and it drove fine the next morning. I was told it could be the transmission breather vent or the transmission filter. But it stopped working when the truck got hot. If anyone knows what it is. Please let me know.
Thanks.
