Can someone tell me how to identify what transmission I have. I have a 4.8 V8 4x4 with a 5 speed transmission. I am trying to replace the clutch, throwout bearing, and possibly replace some tranny parts. From rockauto.com there are several options and I have no clue which ones to choose. I would appreciate any help.

I was thinking NV3500 but I am not certain.

 

Yes, it should be the NV3500 in that year.

You could also use this VIN decoder if you want too.

So my next question is this:

Are all NV3500'set the same? Same input shafts size? Throw out bearing diameters, clutch sizes?

 

Bump, have '03 with nv3500 new clutch coming soon
