Silverado 10 Speed Spill and Fill?

[Yolo]

Would it be ok to do a spill and fill on a 2022 refresh Silverado 1500 ten-speed? I was going to do it every 30K.

I have a large graduated pitcher to drain the fluid into that from the pan, and then I’d just put back in the exact amount that came out. I would do it a second time after driving around for a few miles.

I think it’d be just fine to do a spill & fill.

That is never a bad idea if you are using the correct fluid.

The new fluid is very good so you may consider a 50k mile service over 30k as that fluid will be fine and it's expensive.

That's a "money flush" at 30,000 miles. Go out to 50,000 and you will be fine.
Go to a nice dinner instead.

FWIW I did a transmission service on a 10R140 in our boom truck @ 90k miles, regularly GVCW 30,000lbs and it looked just fine.

I’ll take it to 50k. Thanks guys!

10 speed transmission ?

Do these trans have to be at a certain temperature range to get correct fluid level reading ?

Long time GM owner - mostly LT’s but now Tahoe - I have always just done the pan volume and not the second time you mentioned - doing this 30k-50k is more than many get …
What kind of transmissions temps are you seeing? My 10 speed was just running only 145°F @75 mph - 93°F outside …
Let us know how much drains out please !

I'm also seeing low temps on my '22 Yukon XL. Very impressed with the trans cooling setup.

Would a vacuum pump a la Mityvac work well on these transmissions? Pulling the pan requires exhaust disassembly which isn't appealing to me.

Also, when would you replace the filter? 100k?

I tend to do filters at 50k … was able to put a B&M plug in the 2017 - bcs they sit proud I can only do a gallon - so do that once a year …
It still has the big tube/dipstick - so 15 minute job …
Have not studied the 10 speed enough - only 17k …

I watched a video - that’s allot of work and there must be something different bcs many pans run that close to cross over pipes.

When the time comes - might go see the muffler man about making a spool piece avoiding the O/S etc …

Not sure of the GM history with this trans. From what I’ve read and heard it has a different weak spot than the ford version … TC lockup clutch seems to be the primary complaint, and the first signs are shuddering sensations. A friend of mine who doesn’t do vehicle maintenance and drives mostly highway lost his TC clutch at 120k miles. Dealer said 3k for a new converter with no warranty on the work due to fluid contamination, or 10k for a whole new unit. Dealer told him this was about the mileage they start coming in and if it has problems, this is the pattern they see.

If you are towing, 30k might be wise. Otherwise, 50 is probably good, and every 30-50 after that.

Several of us with Fords have had good experiences adding a partial or full dose of lubeguard red. I use about 25% dosing in mine. @ctechbob runs a full dose in his I believe. Basically the same transmission, minor tweaks between both mfrs, different programming.

I wonder if the converter clutch durability can be helped by eliminating the small amount of converter slip they use for damping? Not sure if the tuner apps can do this or not? If it's friction material delamination due to fatigue then bad on them because we went through this problem at Allison on the 1000 series and they had a good number of transplanted Allison boys and girls up there who knew the story and the fix.

What I've read on the Fords is they have a bushing in one of their rotating drums that slips in its bore and starts to cut off clutch pressure feed passages, an easy design fix via a stepped bore but obviously requiring a complete teardown and replacement.

Ford’s HD transmissions have generally proven more robust than the other manufacturers. A few issues here and there, but less than others for sure when the trucks have been modified.

A 10R80/10L90 or whatever it is will never be worse off with cleaner, fresher fluid. I just changed my factory fill @ 86k on a 10R80 and the visual condition was horrible. If I hadn’t owned the truck for the last 60k+ miles and known the trans was operating fine, I would have been terrified of significant issues due to the color of the fluid and its viscosity. UOA will show me within a week or so how bad it was…

This has been addressed both on the production line and for warranty/replacement parts for earlier versions that failed.

I think getting the first transmission filter change done is more prudent before going to a "spill & fill" regime.

So 0.25oz per quart or 25% of total volume? LG recommendation is 1oz per quart so just trying to understand which ratio you’re meaning.

@meep does a tiny amount. I use the full 1oz per qt routine. I think he's using something like .25/qt.

 

[BrendanC]

unfortunately with the exhaust cross over it’s impossible to get the pan down breaking the exhaust manifold flanges loose.

Drain and fill sure
That's all I have ever done with a filter change every other
Won't do a flush
