2005 Chevy Silverado Z71 4X4 automatic 5.3 liter 75,000mi. Transmission slipping and vibration noise. I have changed all transmission, gear oil, and filters when this first started to happen and double checked all fluid levels this did not correct the problem.
Do you

Has the check engine light come on? ALso, have you owned the vehicle since it was new? When you changed the trans fluid, was the old fluid dirty or have a burnt smell to it?

That wouldn't have anything to do with the trans. If no warning lights came on and the trans is slipping, chances are the clutches are worn or there is a pressure problem in the transmission not fully engaging the clutch pack.

A silly question would the output of the alternator if it is below 14.5 volts cause the transmission to slip based on the signal this provides to the electrical system that would cause a valve to operate incorrectly and if this was a cause would it send a diagnostic code error?

As long as the power remains above 12.0 volts, it won't affect anything.

Any idea on what the cost range would be to replace the clutches or is this a complete rebuild? And how long this normally would take?

Another question would be this is the original alternator how long do they normally last under normal wear conditions.

Basically, the trans needs removed and a basic overhaul is completed. I would estimate around 1500.00 if no hard parts are needed. As far as the alt, it should last over 100K with no problem.

Well to make a long story short I took the truck in and my problem is the troque converter is bad and needs to be replaced. Approx 600.00 much better than a rebuilt transmission cost. Thank you for all the input to all.

That will do it. It isn't building enough pressure to fully engage the clutch packs. I just hope the clutches haven't been damaged from slipping.

Let me know how things work out for you, and take care.

PS: That is a good price for the work.
