What have you done to your other vehicles today.

I think 3 or 4. The muffler is toast, the DS loop that I built took a shot. And unsure if it hurt the transmission internally or not, I will have to get another driveshaft in it to find out.

Carnage picture...

More carnage pictures...

I am having trouble getting a u joint, I have another yoke. But, it's not exactly the same.

Getting the ol Dragon in shape for winter. Had leaking trans lines. Got the old ones off. Radiator came with the front part to the rubber lines.

I gonna save 250 bucks here I am good with that. I needed both lines and both rubber hoses they were wasted. I got a roll of tubing on the way. And it took hours to find but I also got the inverted flare fittings and nuts to join what I am making to the front lines.

I ain't with the quick leak fittings anyway. I prefer the flared ends. No leaks and if I ever got to take it apart they still work. As opposed to the 6 months the quick release got before they are junk and leak if you got to mess with them again.

Poor ol dragon(durango) is the snow car. So all it sees is salt and nasty. Taking it kinda hard on the lines rusting. Good ol truck tho she earns her keep.

Finished up installing headers on the motorhome. New iridium plugs and wires. Runs good and no more exhaust leaks.

Yea, I know headers are worthless with a full exhaust. At least that's what the 'EXPERTS' on the other side of the pond say. Maybe a set of electric cutouts is in the future for the motorhome. Don't want to waste all that money and effort installing headers if they won't increase performance.

I get puzzled looks from friends when they see the headers on my truck.

"Wait... you have headers on your truck, but not on the Chevelles?"

I was able to get my truck up and running again, found a u joint, had another driveshaft and a spare yoke. Been driving it, drivability is crap. I have been going back and forth with the tuner. I did my own research and trouble shooting, it seems like the segment swap for the transmission part of the tune didn't carry over. (He copied and pasted my old tune, then made adjustments) I had the notion to try the PCM from my old truck this morning. I'll be damned, it shifts and locks the converter now.

I am going to pay him a visit this week with my findings and see what happens. I didn't get over there today - I was busy with other things and honestly needed to cool off a bit.

This however is the push I needed to buy HP tuners and learn how to do this type of work myself.

[carpoor]

A good friend of mine stopped by Wednesday afternoon and helped me get the tune mostly sorted out. It runs strong.

After work today, I went over and put a stepside bed on my father's Sierra. Still need to finish the body work and paint it.

Got my truck on the lift over at my folks. The muffler has come apart... succumbed to the damage from the great driveshaft debacle. Have a new one on the way. Also replaced a section of crushed pipe from the same incident. Did a new transmission filter at the same time. Going to install larger transmission cooler too - trucool 40K.

The plugs are shot from detonation during tuning, have a set - just need to install. And the replacement MAF sensor is acting up, so I picked up a genuine GM part.

Lastly, I am going to take measurements and order a beefier driveshaft. The truck should be ready for a final tune at that point.
