Not sure I understand the benefits of adding the 1LE pan on the A10...are we still at 7qts & do we have a p/n / cost??

Thanks.

The 1LE trans pan apparently helps cool the A10 better for track use, from what I was told.

This procedure is shrouded by doubt & obscurity because this transmission is fairly new. I couldn't find a decent DIY so hopefully this will help some of you guys.

You will need 7qts of tranny fluid (GM only) as this A10 requires a special ULV (ultra-low viscosity) fluid. Don't get fancy with any other fluids. GM part #19352619. No drain plug on this pan so be prepared for a little mess. You can remove the little 10mm plug on the driver's front which may drain a quart or so. Proceed to removing the transmission pan bolts (10mm) in a logical way to minimize mess. Be prepared for 6-7 quarts of fluid to drain or spill.

OK...pan is now removed and the filter is retained by two 8mm bolts. The filter will easily come off and be ready for another small rush of fluid. The new filter comes with a new seal which can be installed with finger pressure.

Filter # 24291343
Pan gasket # 24269333

Lube the inside of the new filter seal with a little dab of fresh tranny fluid. Press new seal in place and reinstall the new filter and the two 8mm bolts.

Clean the transmission pan with a little brake clean and remove the two round magnets and clean them too. Replace the gasket (not entirely necessary) and reinstall the pan & 10mm bolts.

OK...here comes the fun part which is adding fluid. No dipstick, no rubber plug to access where the dipstick would be...what to do? You have to add fluid through the little 10mm plug via a pump & small orifice tip. There is a GM tool/fixture for this to thread into the hole. Sorry, this guy isn't buying a special tool. I rigged a pool float inflator to a rubber tube. A simple hand pump from Advance Auto and all is well. The fluid is really thin so it is quite easy to pump. 7 quarts later and the procedure is done.

OK...how to check the fluid to ensure it is correct? There is a procedure to get the fluid to a specific temp and open the plug until fluid stops dripping. I had done this fluid check already so I precisely measured what was drained and replaced. 7 quarts was my number.

Here is some inspiration for you do it yourselfers. I got the A10 fluid change completed at the dealer today and it costs $352.00.

Hey Stephen, I thought you were at VIR this weekend?

How/Why does less fluid cool better? not meant to troll, really curious.

Me too! Perhaps it has external cooling fins.

There is an allen plug back of the trans to fill just an FYI. The fluid doesn't need to be changed and for those of you doing it, don't be surprised if it comes out dark, that's just clutch material suspended in the fluid which is totally acceptable in a clutch to clutch transmission. Also you get the trans to 200 to 210 degrees for the fluid level check.

This depends on the year, 2019 and 2020 10l90 have a fill plug in the rear, my bad on the misinformation.

Stephen, what filter did you use?

something else:
ZLE pan 24298919
ZL1 pan 24290872 (stamped on the pan of my car)
I still don't know the difference between them

[Stephen12ZL1]

This one in the first post of this thread...

[h018871]

thx for the clarification Stephen, you have a '17 correct?
24291343 crosses to ACDelco TF933

hmmmmmm, I had ACDelco TF937, GM 24294355 in my notes for my car. I wonder if they are year specific.

My car is a '17. I don't see any changes in the A10 through the years unless the A10 in the ZL1 1LE has a different pan depth requiring a different filter (doubtful). I see no listing for a TF937 through a quick online search. I would be willing to bet the filter I listed is correct but a quick call to your dealer with your VIN can confirm this part #.

That’ll be the plan for the morning.
