Sorry for the late update, customer is driving the truck and it's been "out of sight out of mind". So the programmer can be removed and the truck runs, it just says it will derate in "x" number of miles. Concern is still present. The biggest issue I have is you can't get the thing to do a crank relearn. I don't know. I'll post an update if I get something. I have basically washed my hands of it now.

Oh, I agree with you whole heartedly on that sentiment. The injectors are in the same spots and 3 and 8 were replaced and IQA's imputed accordingly.

Been a long time since I have posted, but I have head scratcher here. 2016 Chevy 3500 HD vin# 1GC4KYC80GF236554 MILES= 124,000 The truck has a tune on it and things weren't monitored as well as they should and it blew a hole in a piston. The owner drove it to the shop I work at instead of towing it. My man was dead set on gettin her there under her own power, (smokin like a freight train, about to shake the dash out the passenger window, top speed of 35 mph, you know) The engine was replaced with a long block and all was right with the world. Customer picks up and comes right back, says it has a vibration that will chatter your teeth. This is verified at 65 to 75 mph under light accel. Lots of chassis stuff has been checked and found ok, the usual wheels, driveshaft, ect. I noticed that if the RPM deviates too much, then the vibration goes way, like down shifting, or unlocking the torque converter. When the truck is acting up, the fuel trims for 3 and 8 max out at 25. Here is the kicker: if you do a crank relearn, it takes about 70 miles of driving to get the problem to reoccur. Hence the reason the truck was given to the customer the first time with no issues. I appreciate you guys reading this and any thoughts would be super! I am not a Chevy guy but I am convinced that GM hates their techs.

Did a ton of em in my area, real mess, lucky none of them caught on fire.

Looks like they missed a spot, riiiight around the 10:30 area.

up to 20 hours allowable "M" time, I second that!

What's the full repair going to be on that one?

I shop at Harbor Freight, that's where I get my zip ties and bungee cords......that's about it.

I bang the chrome ones on with my rubber mallet, but if they are black, I put the package they come in betwixt the cap and my rubber mallet, no marks that way.

Here in the South, we were shorts about 10 months out of the year and I can't stand to have a frickin' dirty ass air hose rub on my legs, looks like I got whipped with a hickory switch dipped in charcoal.

Oh how I dislike taking ASE tests. My boss at the college called me the other day and said some of my ASE's had expired. One of the requirements to teach is to be ASE master (A1-A8). Well come to find out, all of mine had expired! To say that I was in a bit of bind would be an understatement. I had till May 31st to get A1-A9, L1, L2, and G1 test recertified. So I took 9 ASE tests one day and the last 3 about two weeks later on one day. This required taking two mornings off from my job at the dealer and about 300 bucks. Taking L1 and L2 back to back was a....... exhausting. The bar was set pretty high for me as failing any test would require a 30 day wait before retaking and I had no time for that. I was quite happy with the results. A1-A9 ended up being 250 questions of which I missed 13 total! L1, L2, G1 was 125 questions and I missed around 10. I can say with some confidence that I will not let them expire like that again!!!!!!

I have always been a classic tool guy, you know not much for change. This would include red tool boxes and air tools. I had to pull the powertrain out of a salvage truck yesterday at a friends garage. About the only air tools to be found were air hammers and die grinders. I must say I was quite happy not having an air hose wrapped around my ankles and such, esp. in the interior (I was pulling the cab on a '99 Super Duty). All the tools I used had plenty of power and the batteries lasted the whole time I was there with no issues. The 1/2 impact was a bit heavy though. These were all Milwaukee Fuel units. My favorite item was the little light for the air ratchet, a definite plus! I have considered getting a set but I plan on retiring from the industry and I probably will pass on any new tool purchases.

Too much nitrous!

These things are like a turd that won't flush. I have lost count of how many clutches, TCM's, actuators and even transmissions themselves (cooked from being run low on fluid) that I have done this year. Not sure when it will end on a dealer level but soon it will be on the shoulders of the independents. The warranty extensions have got to run out and some point in time, right? One thing that I have noticed as these things have been in service for a long time now, is any coolant leak at the rear of the engine is a death blow to the clutch system. It sucks for the customer if not dealt with in a timely manner, what could be a relatively cheap hose repair turns into a multiple thousand dollar job. It doesn't help that any fluid that makes its way into the bell housing really has no way out. I have two such units in my bay now and I am sure many more to come before New Years day. I dread seeing what these things will like when low level I don't give a shit dirt bags get their hands on these things. Someone put the clutch snap ring on upside down on the one I did Saturday and jeez is it a pain in the ass to get back off.

I have the power probe version of this and it works great when needed, but I have only used or needed it 2 times in the past decade. Of course my main thing is powertrain work so I'm sure guys that are heavy on the electrical side would get more of a return on investment.
