ok here is the questions... I have a 2001 silverado rcsb with 5.3L and auto. Is it a 4L60 or 65??? I am looking for rebuild kits and want to make sure I buy the right one. MOnster transmissions says its a 65E. I thought I would ask yall the question.. I was looking at buying a tci master overhaul kit... for 512 buks looks like it has everything and also pick up their beast sun shell and a yank tt converter. My brother is ASE certified so we are going to do the rebuild at home. I can save alot of labor money that way and i can dyno test it at his school Lincoln Tech.. Any input is welcome thanks guys.
