Dropping the pan???


Recommended Posts

Posted

Getting ready to change filter and fluid on my 02 z71 with a 5.3. Read on hear that to drop the pan you need to remove the shift cable assembly. Is this correct or can you leave it in place.

 

If it has to go...how do you do it? Also...don't use and impact to try and remove the drain plug. :loser: Don't ask how I know. :chevy:

 

Once the pan is off I'm going to drill out the old plug and put a new plug in place. Has anyone else run into these issues?

I'm taking it you used an impact wrench to take out a drain bolt, which caused a lot of damage, and now you want to take the pain off to drill out the hole.

 

WHich pan are you speaking of anyhow? I imagine the oil pan but then you said shift cables. I'm really lost.

 

You sould restate what your questions if you want some help on this one.

Sounds like the transmission pan. Isn't the pan plug a wierd size or something? If so my guess is he completely obliterated the plug and needs to drop the pan to change the filter and to drill the old plug out... retap it and put a new one in?

Sorry, should have been more clear. Trans pan. I tried everything to get the drain plug out.

 

I rounded off the head...not stripped. I will have to drill it out to get the dern thing loose. Some knuckle dragger at the factory thought it would be a good idea to tighten it so tight that a normal individual can't get it loose.

 

Back to my question...Does the shift cable bracket have to be removed to drop the TRANS PAN? If so, how is it removed

With the 5.3, you're gonna have a 4L60E trans. I KNOW on the 80E that you DO have to remove the shift cable, not 100% sure on the 60E, but I'd guess yes.

 

On mine, the pan bolts are 8 or 10mm (pretty sure) and the linkage has one 10 or 12mm bolt and a torx, maybe 45 or 55 ?? I can double check when I get home, but again, we have different trannies, so it may not be applicable to you :chevy:

 

In any case, have you looked to see what it looks like under there ?? You should be able to tell immediately if the linkage needs to come down.

 

Oh- and I didn't do anything with the cable or it's adjuster, just remove the bracket as an assembly. I also seem to remember having toput it in neutral to access one of the bolts.

 

Hope that helps.

Yes, I was under their for quite a while trying to remove the plug. It doesn't look like it needs to come off. The black stamped steel bracket is mounted to the trans housing above the pan bolts. I was under the impression that it caused interference when removing the pan.

 

maybe I'm wrong - but I swear I can't see any Torx head bolts anywhere on that bracket.

 

FYI - a new plug for the trans pan was 5.37 at the dealer.

The torx bolts can not be seen. You have to do it by feel. They are easy to find. just feel around above the shift linkage and you will find them. I had 2 torx holding mine on and I believe they were T45 but I can't remeber. I'm having trouble with the search function but I thought it was on this site that I found that before. Mine is the 4L60e. Quad is right I didn't disconnect the linkage just unbolted the bracket to move it over a little.

 

Good luck with the drain plug. Messed with mine 3-4 times before I got it loose. :chevy:

Right, you couldn't see the torx bolt w/out an inspection mirror.

 

Just run your fingers around on top of the linkage bracket and you'll feel a *button-head* bolt- that'll be your torx.

 

Mine only had one torx, the other was a hex.

 

 

About the linkage coming off, I could be wrong. Again, mine's an 80E.

Thanks for the info on the Torx...If they are above the pan mounting surface and you can only see them with an inspection mirror...how in the he!! are u supposed to get a bit on them???

 

I have the deep pan and the cable runs along the passenger side of the pan. This still sound right?

My torx bit was a 3/8 inch ratchet bit. I could feel the bolt and stick the bit in the bolt head. The bit will stay in the bolt head on its own. Then I would put the ratchet in the bit. It wasn't too bad you just have to do it by feel instead of sight.

 

I really thought mine was on the drivers side but I may be wrong. It has been awhile. Seems to me there was a heat shield up close to the passenger side pan mount and the shift linkage wrapped around the driver side pan mounting surface. Maybe the 02 is different.

Man I sure hope so. Hey since this is my thread...anybody know off the top of your head what the capacity is of the auto transfer case. Going to do that as well and bought 2 quarts. Think that will be enough?

Posted

It will be close. I just went to the dealer and said what will it take and they sold me 3 quarts. I didn't use the entire 3rd quart but I did spill some (allot- kicked bottle over) so I'm not sure if 2 will do it. If 2 is enough it will be just barely. Also did you get it from the dealer? I've heard it is a dealer only fluid.

 

Tip - Don't take the lid off the bottles until your ready to pour. You will kick it over when your trying to get the dang creeper to roll over a pebble. :chevy:

Yep bought the factory stuff...when I asked the "gentleman" at the parts counter how much it would hold he just looked at me and said...I don't know...I work in parts!

 

I said "no chit! I thought I was in the mens room" He didn't laugh. But I did...inside that is.

I just pry the shift cable mounting bracket aside and then back into place, if you don't want to pry, you will have to remove the bracket and push it all aside. Last time I did a transfer case change it took almost exactly two quarts, but I'd buy three, wouldn't want to come up 1/8th a quart short or something!

 

Also, be careful on the transfer case bolts, the d**n thing is made out of magnesium (I think) and strips EASY! Remember, it only has to be snug. On that note, be very gentle on the transmission bolts, putting much more than minimal snugness on the bolts can split the gasket and cause a leak.

10-4. I got this thing in the bag. I'll let you all know how it goes Monday. If you don't hear from me then it musta went really bad. :chevy:

    • This is a 1/2 ton thing ONLY.  All HDs 2020-2026 have the two speed transfer case, with Autotrac as an option.     1/2 tons 2019-2026, regular 4x4s come with a single speed case (no 4LO!), and trucks with Z71 ordered, or all Trail Boss trucks come with the 2 speed case.  2 speed case is also an option on WT, and is also standard on High Country.  
    • 2013 5.3 still to this day calls for the PF48 filter.  Which as a 15psi bypass pressure.     There is a TSB, 17-NA-157 that talks about the PF-63 and PF-64 filters which have a higher bypass rating of 22psi.    TSB HERE - temp.xml   "Beginning in 2012, the oil pumps began to regulate main gallery feedback instead of pump out pressure. This means that the oil pump now does not begin to regulate until pressure is built up to the main gallery. This change reduces the amount of time it takes to provide oil to the engine bearing and lifters during extreme cold start conditions.  Main gallery feedback oil pump control systems are present on the following engine families which use Spin-on oil filters: Small Gas Engine (SGE), Large Gas Engine (LGE), High Feature (HFV6) Gen2 and Small Block Gen5 gasoline engines. These engines with the main gallery feedback oil pump control systems are factory built with an ACDelco® oil filters"   It also calls out what engines use those filters.  The gen 4 small blocks were not on that list (LMG, LC9, L9H, L92, L94, L20, L96).  Gen 5 small blocks use the higher pressure filter.          That all said...   Your 7045 Napa filter is the PF63 equivalent, with 22psi bypass.  You are already using the higher bypass pressure filter.  You CAN keep using it, you don't technically have to use it though.  
    • Do you know WHY the filter relief setting was increased to 22 psig?    When the new system goes into the second stage the pump volume ramps up considerably. It was found that the 15 psi filter bypass setting put the filter in bypass on a warm engine when the second stage was activated. Raising the filter bypass setting forced the filter to do what it designed to do. Filter. Preventing debris from circulating during high load, high rpm operation.    So next question is how did GM find this out? VLOM/lifter failures and a deep dive by Melling Corp.    Last question. Is it required? Look at it like this; a motor may be equipped with a rev limiter. But it only works if the set point in reached. That 22 psig setting only matters if the pressure differential across the filter media exceeds 15 psig during normal warm operation. Second stage kicks in around 3000-3500 rpm.    I can't answer your question because I don't know you and how you use the truck. But I think there is enough information here to let you decide for yourself. 😉
    • Probably not their first rodeo, so it should go as planned most likely.  Typically the service manager or tech doing the swap will put some seat time to shake it down after they get it all put back together.  We usually put 50-100mi before we hand them back so if something happens, its not after you get it.  A coolant leaks, oil leaks, a ground left off or loose, vibration, etc.     The new engines so far have been good?  There's been a couple that have popped out there again (the replacement engine) but most have been okay.
