Stumped P1740
 

I just rebuild this trans in my truck. its a late model 2006 put in a transtar triple disc convter new alto clutches sonnas 2nd gear super servo sun coast billet band anchor and apply par used oem 5:1 lever new sonnax accumlator piston new gaskets oem front pump low rev band an superior shift kit.....everything shifted fine for the first 220ish miles then threw the code and now i dont have lock up in 3rd or 4th.....put in a new borg warner gov pressure solenoid and new tcc od solenoid an still same issue....


Anyone have any input on this????:argh:

You may have a bad connection? Did you check compatibality?

Its not any connection issues...spoke with converter company...transtar an gonna pull it out an maybe at this point try to get my money back n get a sun coast unit....so i dont gotta deal with pullin the trans again....an inspecting it all once more an praying to the diesel gods i didnt wipe out a clutch pack...or any other internals
:dang:

So to update the issue...pulled trans pull it apart the tcc cover plate had loosened an had no pressure to apply the converter clutch. Trans goes in tomorrow also added a new hd one piece input shaft from sonnax also a new DTT flexplate with arp bolts holding it in!:bat:
