Ford Repair Questions? Ask a Mechanic for Answers ASAP
hello, did you use a used transmission and what problem did you have with the old trans which lead to replacement?
Ok and all you are getting is a code P0735 for a 5th gear ratio fault or you have other codes as well?
Ok, then here is the issue. The used trans you installed has a problem with the overdrive band servo piston that applies the band. The case bore the servo piston slides backin forth in is messed up. There is a repair kit out to drill out the old bore and install a wear sleeve to fix this, but it requires removal of the trans like an overhaul to do so. The servo piston gets stuck inside the bore and cant apply the band properly.
No, if you had an issue with a speed sensor, it would set a seperate code for it and would have more than one gear ratio fault. Since its one gear only, the problem is in the trans.
