Trans Service What A PITA

I did the differentials and my transmission today. The trans was a PITA. With the exhaust cross over pipe in the way, I had to undo rear trans mount, jack up trans and pry exhaust down for pan removal. :happysad:

I remember doing my 2006, I actually did it while the engine was out, but it was still a pain and I still somehow managed to break the shift cable.

lol.. I was just gonna search the forum for "transmission filter" because I wanted to do this as well. But i watched a few videos and they all say the exhaust cross member is in the way.

Personal decision. I know it was done right. Retired so I have the time. I have always done my own maintenance. :happysad:

I hear ya. I did all my fluids last summer, but my research on that one had me open the wallet. I wish I had a lift in my garage...

Do all my own maintenance too but this is too much for the driveway for this oldster. My dealer won't even do it, they use the exchange method.

I tried to raise the trans and still couldn't get it. got nervous I was going to damage something in the internals so I finally cut the cross pipe got it done and got the exhaust welded back. the 100 it cost me to get it welded back may be cheaper to just let the dealer do it. I never called them to get a price

Now I can't say for sure about OP's with (presumably 6L80), but with my '12 and 6L90, there was plenty of room to drop the pan out without doing anything else. On any older truck with a 4L60 (<2008), pan removal is easy. Take a prybar and gently tweak (not bend) the shifter bracket to the side as you're lowering the pan. It'll clear and you won't have to remove anything else.

My trans is the 6L80. My 93 was easy.

Prices in my area for both differentials and trans filter and refill were dealer -$600 + shop add on's, $500, independent shop.

I bought trans fluid on sale and got a 20% off coupon for diff. fluid.

Cost me just under a $100 for fluids, trans filter and 5 hours of my time.

I just do a passive flush on the trans & don't bother with the pan. Much less of a pain and a better way to service the trans, as it fully replaces all the fluid, not just part of it. The filter can stay in for a long time with no ill effects. The fluid is the critical part & should be fully changed.

That's what I did when I couldn't get the pan off no matter what I tried. I'm at 52k now and figure I can go awhile before messing with the filter

Used to have fluid exchange done at Jiffy Lube on our vehicles. I thought I would replace the filter after break in. I will now remove fluid every 10k miles through trans dip stick tube with vacuum pump and replace what comes out. Time will tell. :happysad:

How is this done??

      What a wonderful result! Great story telling to. You are quite multifaceted sir.  I'd keep it. Four is my limit too and yet we have five as well. One assigned the 'salt car' to do all those tasks you hate to ask of your 'Save for Good" crowd. 😉    Don't forget the antifreeze.    The Iron 4.3 is a favorite of mine.

      Ancillary parts to the lower intake and connections went together without issue.   There was a brief pause when I leak-tested the fuel lines and injection system. Fuel was spraying all over. Lovely. O-rings weren't sealing the fuel lines to the spider, and inbound line was leaking at schrader valve, leaks at both flange nuts. It's moments like those when you just want to set fire to the whole shop, and be done with it. I was mostly enjoying the project up until that point, and was tracking to an agenda of having a running Blazer and a cold beverage in hand by dinnertime.    I found some larger Viton o-rings for my spider and some grease to get them to seat. One leak solved. Swapped fuel line Schrader core for old core. Still leaked. Swapped entire valve for old valve. Leak solved. Nudged the flange nuts a little tighter on the connections. Another leak solved. I could cycle the key / prime the pump and the intake was staying dry.    Reassembled the upper intake, with 10,000 vacuum lines, and filled the cooling system with water* (this is temporary, I'm not done with the cooling system yet).   Showtime!!   Cranked it over and smoke billowed, it was running rough. CEL illuminated and began flashing. P0300 and I somehow tripped a code for the TPS sensor, voltage low.    There's nothing as unrewarding as a vehicle that won't run (and produces the same code/problem) after hours of research and work.   Clearly I was in over my head. Was the timing off, did I stab the distributor incorrectly? Is the new distributor bad? With my limited OBD 1.5 data stream I really don't have a lot of parameters to see. The engine was pulling mad timing again (flooding?).   Think, Atlas, think.   1-6-5-4-3-2. One, six, five.....four, three, ....two. Wait a second. That makes no sense. 1 is the forward cylinder on the driver's side, so 2 should be the forward cylinder on the passenger side, not 6.    I can't believe it, but I'm looking right at it. Swapped 2 and 6 on the distributor and turned the key over, and...   It fired, coughed and stumbled, smoked, and then settled into a smooth idle. The scanner showed no codes, no lights on the dash, and the throttle was nice and responsive to gentle revs while it warmed up.   It's working!!! IT'S WORKING!!!   I paused for a late dinner, no cold beverage yet. I was determined to do my shakedown run. Did a basic safety and fluids check one more time and then went out and put almost 70 miles on it last night. She's a runner, runs good.   Came home and did a post-trip, post-mortem. The underside is dry *except* for where the last owner RTV'd the snow out of the intersection of the timing cover and oil pan. He said he had replaced the timing cover seal, but, my dude had clearly done it incorrectly and then tried to hold back fate with black RTV. Never works.   Yesterday morning I replaced the broken driver's door mirror. As much as I hate cheap Chinese parts, thank goodness for cheap Chinese parts. I think an entire new power mirror assembly cost me like $30, and it works perfectly. Replacement tail lights (faded, and one was busted) ran me about $12/side. I have a door pin kit ready to go in because the driver's door sags just a little and I want to fix that because there's nothing sadder than a saggy door.   I don't know what's next for this rig. Half of me wants to take some nice photos (there's a park nearby with a HUGE American Flag that always seems to be catching wind) and throw it up on CL/Marketplace for a couple grand and see if it flies. The other half of me... I've got a sweet running S10 Blazer that's been keeping my mind off of whatever I'm going through right now, and it's bringing some joy, and is cheaper than therapy. Maybe I'll keep it around for a little while. However, this is my 5th vehicle, just for me. 4 is really my limit, but they are not junk, so need very little attention. I don't know...there's a point where it's just too much and I don't see owning this truck long term. But I solved its major problem, got it running, so I'm going to stick a feather in my cap for now.   Sometimes we just need to get our hands dirty and fix something in the physical world to gain some satisfaction.
