I just got quoted $1000 from my dealership and just around $1000 from a local mechanic to do above job. I am relatively handy and do most maintenance myself, tranny’s just scare me. How hard is the 8-speed to do with dropping the exhaust etc? Any way around not having to drop it or other information such as torque specs, reuse bolts, etc would also be appreciated by guys that have done it themselves.

It's not hard. The biggest thing is getting the exhaust out of the way.  There are video's on YouTube.

$1000 seems excessive.  About 2.5 to3 times more from the estimates  i seen..  the low end about $250 and the high end $350.    At least here in the Midwest  flyover country of Central Illinois

You don't have to drop the exhaust to do it.  A slight pull on the crossover pipe with a pry bar will lower the exhaust enough to get the pan out.

The lower end quotes that you guys got I think are just for a fluid flush. They don’t touch the pan or filter with that. I want to change out my filter and not do that flush. I’ve looked online and on you tube and haven’t found a good video yet of how to do it. Gangly- do you have a good reference or process that I could look up on how to do it?

I found the size of the fill plug in the case for my 10spd in my HD. I bought a 1/2" hose nipple with that thread on it and bought a length of clear tubing. To fill the trans after a service all I need to do is screw the nipple in to the case and run a length of hose up to the traditional space for a dipstick and then pour in the same amount that I just drained out when I dropped the pan. This way I dont have to pump the fluid UP into the side of the case and I avoid the screaming hot cat while filling it. 

I get the feeling that the lack of familiarity with these transmissions is causing some price gouging. The filter isnt a big deal and the ULV fluid for mine is under $5 qt at Rockauto.

      2007 Silverado classic Cooling fan running

      By Mistycool · Posted

      I am having similar issues.. 08, 4.8L granted I did had a fender bender and minor damage up front passenger side but I don’t think it had anything to do with it.. I had the high and low pressure checked and my fan for my radiator keeps coming on.. replaced the pressure switch and don’t want to keep throwing parts at it. I did have some minor problems here and there like on long road trips sometimes the ac would get a little warm and then on the highway as soon as I give it a little gas or get a little heavier on the petal it started running cooler. Never had an issue with the ac besides the here and there.. but I also started having issues when I fuel up now it takes a bit to start ( super embarrassing) it runs fine and once started ( only happens after fueling up) starts fine any other time. Could they be related?

      Spent a small fortune on fuel this weekend.   $6.69 diesel, 18 gallons of that. $6.99 92-octane ethanol free, 10 gallons of that for yard machines $5.59 87-octane for one of the cars, 11 gallons.   $250+ and I didn't even get a tug.   Hormuz ain't Hormuzin again, did not see that coming...LOL

      Appreciate the advice. I've watched multiple videos. Most showing the most complex for those that have a center console, to one that showed maybe 2 pieces of trim being removed, like 6 screws, pulling back the screen and switch assembly, and installing the inline module. And this was a new/newer Silverado. That didn't look too bad. All the others show alot of trim pieces that need to be removed. I've broken those kind of tabs/clips on my C8 Corvette trying to get to the battery, and that was a lot less clips than what I think is involved here after watching multiple videos and looking at my dash today. I have one on the way. Called a reputable stereo place about installing it and got a "minimum" price of $175. Ouch! Looking forward to seeing what the instructions have to say.

      Ac not keeping up

      By Atlas · Posted

      Hard to say what the issue might be. Anything from the ability to cool the AC condenser up front, to blend door issues in the HVAC unit, to refrigerant charge, to compressor issues or issues in the lines.   Report back what the techs find on the 29th.   GM has service publications which list acceptable vent temperatures and AC pressures at given ambient temps and humidity. They probably won't touch the system if it's operating within those ranges.   I'm also surprised to hear your 2024 with the L8T is still using R134a? I was pretty sure the HD's had switched to the new refrigerant around 2020.
