Wow! If you have the ability to pull the heads get them to a machine shop, you can have them rebuilt. Get yourself a good cam and do an AFM delete. You won't have near $6K into it. Do a search on here as there are several posts about people who have had the same issue and replaced the problem...
Sounds like a battery to me. Sometimes batteries do what you described. Work one minute, not enough juice the next to crank over the engine. Especially if you are unsure of the age. Did you look at the date on the battery? Not sure why you still couldn't jump it.
Added a 20" spare tire so it will work with the front Brembos. And yes a 275/55/R20 will fit in place of the 265/70/R17. You just have to make sure you move it so it doesn't catch on the heat shield on the way up.
What's your recommendation if say a 6.2L with a 2.3L Magnuson was attached to this 6l80e? Same parts or would you change anything?
Thanks as I'm sure mine will need a rebuild in the not so distant future.
Well, after replacing the voltage regulator and the battery still draining down, I took the car to a shop which promptly told me the voltage regulator was bad. So lucky for me I had a receipt from them showing what they had to replace. Help my case with OReillys in getting the part refunded.
That's like asking if a bear poops in the woods.
GM sent out letters to owners saying they would cover condensers on certain vehicles that were identified to have been installed with the faulty units, up to a certain number of years or mileage. Of course mine tanked after that period.
