Replaces the internal oil filter and pan gasket on the GM 5L40E and 5L50E five-speed automatic used in the Cadillac CTS, SRX, STS and BMW X5.
If you drive a 2001-2006 BMW X5 3.0, a 2003-2004 Cadillac CTS 3.2, a 2004-2008 SRX or a 2005-2006 STS and the transmission has started to hesitate into gear on a cold morning, flare on the 2-3 upshift, or smell hot after a long climb, the first job is a pan-off service. This kit is the in-pan oil filter and the oil pan gasket for the GM Hydra-Matic 5L40E and 5L50E five-speed, cross-referenced to 24117-510-011 and 96041844. BMW tags the same transmission as the A5S 360R or A5S 390R, which is why a GM part number turns up on a German SUV.
These are longitudinal, rear-drive five-speeds built by GM in Strasbourg, France. Everything the unit does runs through one pump at the front of the case: it feeds the clutch packs, the valve body and its solenoids, the converter clutch and the lube circuit. The filter sits in the bottom pan and is the only thing between the pump inlet and the sump. As frictions wear they shed fine material, and on a high-mileage unit that has never had the pan dropped, the filter media slowly loads up. Restricted suction lets the pump draw air, line pressure gets unstable, and the first places you feel it are cold engagement and the clutch-to-clutch shifts. GM lists dry capacity at about 9 quarts, but a pan drop only exchanges part of that, so a dirty fill takes more than one service to clean up.
Be realistic about what a filter can fix. On these units the valve body bores wear and the solenoids and accumulators get tired, and a cracked reverse/direct housing or worn pump sealing rings will not respond to a fluid service. If the trouble is mechanical, the filter is still the first thing you replace during the repair.
Check the fluid at the level-check plug with the engine running and the fluid at operating temperature; low fluid alone can produce every symptom above. Then look at what comes out when you drain it. Clean red fluid and an occasional flare point toward pressure control, and a gauge on the line pressure tap will tell you more than guessing; our line pressure testing guide walks through it. If the scan tool shows a gear ratio code, read the gear ratio code guide before spending money, because a slipping clutch pack sets those codes and a filter will not cure it.
The listing covers the BMW X5 3.0 inline-six from 2001 to 2006, the Cadillac CTS 3.2 V6 from 2003 to 2004, the SRX 3.6 V6 and 4.6 V8 from 2004 to 2008, and the STS 3.6 V6 and 4.6 V8 from 2005 to 2006. Do not choose between 5L40E and 5L50E by model year. GM documentation summarized by Transmission Digest says Cadillac used the 5L50E only behind the 4.6 V8, so a 3.6 SRX or STS carries the 5L40E. The ID tag is on the left rear of the case just above the pan rail; on a BMW, the tag carries a G or Z code. Match the old filter and the pan bolt pattern, or send us your year and VIN and we will check it. Every part we carry for this family is on the 5L50E parts page.
The filter is serviced with the transmission in the car. Drain the pan, remove the pan bolts, and lower the pan level so the fluid left in it does not spill. Pull the filter straight down so the neck seal comes out with it; if the old seal stays in the case bore, remove it carefully or the new filter will not seal and the pump will suck air. Clean the pan and the magnet, scrape both flanges clean without gouging the aluminum, and fit the new gasket dry. Snug the pan bolts in a cross pattern to the factory torque rather than cranking them down, which distorts the flange. GM specifies Dexron III for the Cadillac 5L50E; on the BMW, use the fluid BMW specifies for that transmission. Refill at the level-check plug until it just begins to run out with the engine running and the fluid at the factory check temperature. If the fluid you drained was full of debris, plan for the 5L40E/5L50E gasket and seal overhaul kit or a replacement valve body rather than repeated pan drops.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
Yes. The listing is built for both transmissions in the applications shown: 2001-2006 BMW X5 3.0, 2003-2004 CTS 3.2, 2004-2008 SRX and 2005-2006 STS. If your old filter or pan looks different, send your year and VIN before ordering.
Read the ID tag on the left rear of the case just above the pan rail. Cadillac paired the 5L50E only with the 4.6 V8, so a 3.6 V6 SRX or STS has the 5L40E. BMW units carry a G or Z code on the tag.
GM specifies Dexron III for the Cadillac 5L50E. BMW X5 owners should use the fluid BMW specifies for that transmission. Fill at the level-check plug with the engine running and the fluid at operating temperature.
GM lists about 9 quarts dry for a fully drained, overhauled unit. A pan-and-filter service only exchanges part of that, because the converter and cooler lines still hold fluid, so buy enough to fill to the level plug and top off after a drive.
Sometimes, if the slip came from a restricted filter or low fluid. If the fluid is burnt, the pan is full of friction material or the scan tool shows gear ratio codes, the clutch packs or valve body need work and the filter is just the first part of that repair.
