Ok where do I start? My overdrive light starts flashing off and on and when its doing that and I go to slow down it kinda has a rough feeling going back into first gear. I have had it rebuilt and it done this with the first transmio. It has a small leak from the front main seal. would this might have somthing to do with it or is it computer problems?

 

There are about 50 things that can go wrong and make the OD light flash. I can't tell which one it is until you have the codes read. It takes a high end Ford specific scan tool to read Ford transmission codes.

 

Ok Thanks man
