A 304 stainless drain plug with a high-temp rare-earth magnet that pulls the fine metal your filter can't catch, so it never ends up circulating back through the transmission.
If you own a Traverse, Acadia, Enclave, Equinox, Malibu, Impala, LaCrosse or SRX with the GM 6T70 or 6T75 six-speed, the drain plug is the only service access you really get to the inside of the transmission. This 304 stainless plug replaces GM 8654382 / 444613 and carries a high-temperature N48SH neodymium magnet, so every fluid change pulls out the fine steel that would otherwise keep circulating, and every time you pull it you get a look at what the transmission is shedding.
On most older automatics you drop the pan and change a filter. The 6T70 family does not work that way. ATRA's 6T70 seminar lists the pump fluid filter as non-serviceable: it sits inside the case and GM only expects it to be replaced after an internal repair. Routine maintenance is a fluid exchange through the drain plug, and GM service information puts a drain-plug fluid change at roughly 4.0 to 6.0 liters (4.2 to 6.3 quarts) of Dexron VI. Because the filter never comes out on a normal service, a magnet at the drain point is one of the few ways to remove wear metal from this unit between rebuilds. The listing rates this magnet to hold past 302 F with more than 2.2 lb of pull, well above the temperatures the fluid normally sees.
A drain plug does not fix a failing transmission, but it is the cheapest early-warning tool you can put on a 6T70. What you find on the magnet matters:
Check the fluid level the way GM and ATRA specify: level ground, engine idling, transmission fluid temperature between 180 and 200 F, then read the level. Pull the plug onto a clean rag so you can see the debris pattern. If you find large steel pieces or have a stored P0776, read our 6T70 common problems and fixes guide before refilling, because GM's repair for wave plate debris is a teardown with a full clean-out, not a fluid change. Owners of a three-row crossover should also look at the 6T75 Acadia problems guide, which covers the same family as the Traverse and Enclave.
This plug is listed as a direct replacement for the GM 8654382 / 444613 drain plug used on 6T70 and 6T75 transmissions in Chevrolet, GMC, Buick, Cadillac, Pontiac and Hummer vehicles, roughly the 2007-2019 model years. It does not cover other GM units like the 6T40 or 6L80, which use different plugs. Before ordering, compare the plug in your pan to the 8654382 / 444613 part number, or send us your year and VIN and we will confirm it. You can see everything else we carry for this unit on our 6T70 / 6T75 parts page.
If the magnet shows the transmission is already coming apart, the drain plug goes back in a rebuilt unit. The 6T70 master rebuild kit covers the overhaul, and a unit with harsh, firm shift complaints after the repair is often paired with the 6T70 shift kit. CNC machined in Wisconsin and shipped from the USA.
| Fits | GM 6T70 / 6T75 transmissions (replaces 8654382 / 444613) |
| Material | 304 stainless steel with N48SH neodymium magnet |
| Magnet rating | High-temp, holds past 302F, over 2.2 lb pull |
| Install | 7/16-inch wrench, aluminum crush washer included |
| Catches | Fine ferrous particles the filter misses (below 35 microns) |
| Ships from | USA (made in Wisconsin) |
Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
No. The pump fluid filter is inside the case and GM treats it as non-serviceable; it is only replaced during an internal repair. Normal service on a 6T70 or 6T75 is a fluid change through the drain plug, which is why a magnetic plug is worth having.
It is listed as a direct replacement for GM drain plug 8654382 / 444613 used on the 6T70 and 6T75. Those transmissions are in the V6 Equinox and Terrain, Traverse, Acadia, Enclave, Malibu, Impala, LaCrosse and SRX. Match your existing plug to that number or send your year and VIN to confirm.
GM service information lists about 4.0 to 6.0 liters (4.2 to 6.3 quarts) for a drain-plug fluid change on the 6T70/6T75. Refill with Dexron VI and check the level with fluid temperature at 180 to 200 F.
A light gray film is normal wear. Steel flakes or chunks usually mean a mechanical failure, and on early 6T70 units the broken 3-5-R wave plate is the most common one. If you also have no 3rd, 5th or Reverse with code P0776, plan on a teardown rather than another fluid change.
Use the aluminum crush washer included with the plug. Crush washers are designed to seal once, so do not reuse the old one, and tighten the plug firmly without overtightening into the aluminum pan threads.
