Looking at buying a used '97- seller said that when he puts it into fifth, nothing happens, no grinding, no nothing, just revs freely like it's in neutral - is this the symptoms of the fifth gear nut having backed off or something more serious? What's it cost to get the fully splined shaft to repair? Thanks!

Thats it. Happened to me on 2 of my 3 dodge trucks.

 

If the shaft/splines and gear are still in tack than it would be as cheap as a new updated nut( maybe $50) and taking the back of the tranny apart and installing it.

If the shaft/splines are not good than the entire tranny needs disasembly to replace the shaft.

Go to quad 4X4 and read about it there. Looks like a good shop and good products.

It sounds like most of the time you can just put a new updated nut on and its fine.

 

Go to Quad 4x4 5th gear problems and fixes to get all the info you need and learn the RIGHT way to fix it.

 

Could also be the snap-ring that holds the 5th gear synchros on the shaft. BT,DT.
