OEM separator plate for the GM 4L60E valve body, with the paper gaskets and filter screens already bonded to both faces so you skip loose-gasket fitment.
If your Silverado, Sierra, Tahoe, Yukon or Suburban with a 4L60E has started shifting soft, flaring into 2nd or 3rd, or feels lazy even after a fluid change, and you already have the valve body on the bench, the steel plate behind it deserves as much attention as the valves themselves. This is the GM Genuine Parts 24241783 spacer plate, sold with the paper gaskets and filter screens already bonded to both faces, so the plate drops onto the case as one piece instead of three or four loose parts.
On the 4L60E the valve body bolts to the bottom of the case with this plate sandwiched between them. Every passage that feeds the 1-2 and 2-3 shift valves, the accumulators, the TCC circuit and the line pressure circuit crosses the plate through a sized hole, and those holes act as orifices that set how quickly each clutch and band applies. The check balls sit in pockets on the case side and seat against the plate. When the plate is right, the solenoid commands the computer sends turn into the shift feel GM calibrated. When the seats around the check balls are hammered out or a gasket has cracked, fluid bleeds from one circuit into its neighbor and the shift goes soft or overlaps.
The bonded construction matters here. With a loose-gasket plate, a gasket that shifts a few thousandths while you lower the valve body can partly block a feed hole. Here the gaskets and screens are fixed to the steel at the factory, which takes that variable out of the job.
Pull the pan, drop the valve body and look at the old plate under good light. Check-ball seats that have gone oval, a shiny wear ring around a seat, torn or blued gasket material, or a screen that is collapsed or missing all justify a new plate. The plate is only half of the hydraulic story, so vacuum test the valve body bores before you spend on parts: our 4L60E valve body wear guide explains which bores fail and what the readings mean, and the pressure regulator and boost valve wear guide covers low line pressure that a plate alone will not cure.
The listing covers the GM 4L60E (and the earlier 4L60 naming) by OE number 24241783. The 4L60E ran from 1993 into the 2010s in the Silverado 1500, Sierra 1500, Tahoe, Yukon, Suburban, S10, Sonoma, Blazer, Camaro and Corvette, and GM changed the plate hole pattern more than once during that run; the aftermarket splits 4L60E plates into separate 1993-94, 1995, 1996-06, 2005 Corvette, 2007-08 and 2009-15 versions. That means this plate is not universal across every 4L60E. Match the number stamped on your old plate, or compare the hole and screen layout side by side, and if you are unsure send us your year and VIN before ordering. Every other plate and valve body we stock for this transmission is on our 4L60E parts page, including the lower-priced GM 24241782 plate for applications that call for it.
Most people doing this job also replace the filter and pan gasket and refresh the solenoids while the valve body is out. A 4L60E solenoid kit with harness, filter and pan gasket covers all three in one order. For the full bench procedure, see our 4L60E valve body rebuild walkthrough.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
No. The upper and lower paper gaskets are bonded to the plate, along with the filter screens. Install it dry with no extra gaskets or sealer.
No. GM revised the 4L60E separator plate several times, and plates are generally grouped as 1993-94, 1995, 1996-06, 2005 Corvette, 2007-08 and 2009-15. Match the number stamped on your old plate or send us your year and VIN to confirm.
Both are genuine GM 4L60E separator plates sold with gaskets, but they carry different part numbers for different applications. The 24241783 has its gaskets and screens bonded on. Use whichever number matches your old plate or your VIN lookup.
Sometimes it is part of the fix, but in the 4L60E a P0741 or slip complaint is very often caused by worn TCC regulator and isolator valve bores in the valve body. Vacuum test the bores before assuming the plate is the only problem.
Fill with Dexron VI ATF and check the level hot. After the job, clear any codes and run the transmission adaptive relearn with a scan tool, or drive through repeated gentle full upshift cycles so the computer resets its shift pressure tables.
