A couple of weeks ago I took my 300F to a local transmission shop to attempt to cure the titled problems. The manager is an old car guy (he owns a 60 Caddy) and was familiar with the problem. He kept the car in a bay for two weeks and wouldn't you know, the old beast didn't leak a drop, so the shop didn't want to tear into it with no obvious symptions. Can't blame them. But the manager did suggest a potential solution. He said he could put a one-way valve in one of the cooling lines, and that this would prevent converter drain back. He said that some later model Dodges had this valve installed at the factory to prevent this situation from occuring. Has anybody out there heard of this solution, and are there any opinions on whether it would work? Terry McTaggart in Dayton Oh.
