The title pretty much says it all. I'm 90% sure that the convertor in my 4R100 is heading south. Ford won't cover it under warranty, silly me I assumed that was included in the 100K drivetrain warranty. 70,000 miles on it, and it's slipping real bad, especially when towing. I don't think it's the lockup because it slips under acceleration when it's not supposed to be locked up. The tranny feels fine, shifts real hard. I use a hypertech prgrammer on it, and tow about 12K I'd say 40% of the time. It's in for other warranty work right now, but I'm going to have it looked at whenever I get it back, but I'm shopping now for convertors just in case. I will not replace it with OEM garbage. 2002 F250 2WD. I've searched the forum and not much on the subject.

 

How about a Stallion....i hear they're pretty tuff.

Thanks PSNut, you spent some time on that post. Can anybody verify that the base warranty does or does not cover torque convertors? This is a subject Ford will keep hidden as well as possible. I asked the service manager about this and he claims that it only covers the motor after 36,000 miles. I was told the base warranty had a 100,000 mile drivetrain warranty, but I am still searching for a detailed list on their definition of "drivetrain".
