OK Ladies and Gents, I have my 95 F350 Dually, and this truck is my baby, I always wanted a Crew Cab 7.3. and after years of searching, i finally found it. Anyway, I spend the first ande second of the Year Hauling Older Fords out to a friends house for him. and Now, i have my O/D Light flashing and she is a gutless wonder. anyone ever have these issues before? where can i start?

 

The only place to start on that is to get your codes read. The OD light means you have a transmission code and your local autozone most likely can't pull it. You need to go to someone with a real scanner.

Honestly there's only two options here, well maybe three. It's something stupid simple, an electrical problem (loose/dirty connection), or an internal transmission issue requiring the trans to come out and gone through.
