hello, did you use a used transmission and what problem did you have with the old trans which lead to replacement?

Customer: replied 1 year ago.
i did use used tranny and the old one was skipping to get into 4th and the rpms would go real high and skip to get into overdrive so i called a specialist and he told me it wasnt worth fixing and to get another one and this one wont go into overdrive and overdrive off light keeps blinking and when i shut it off it resets and does it all over again

Ok and all you are getting is a code P0735 for a 5th gear ratio fault or you have other codes as well?

Customer: replied 1 year ago.
I dont know about any other codes i took it to advance and they put their gun on it and that is all that came up was incorrect 5rh gear ratio
Expert:  HDGENE replied 1 year ago.

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.

Will it mess up anything if i drive it like that
Customer: replied 1 year ago.
is it possible that one of the sensors are bad
Customer: replied 1 year ago.
He did not change the sensors
Expert:  HDGENE replied 1 year ago.

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.
