4T65E Sprag Clutch 1996-2002, new and ready to install. Fits the 4T65E. Ships fast from the USA.
Searching for a fix on a 1996-2002 GM front-driver whose transaxle slips pulling away or goes soft in third? This is the A84658C dual sprag (industry 84724C), the input clutch and third clutch one-way assembly for the late 4T60E and the 4T65E up to the 2003 redesign. It suits the Lumina, Monte Carlo, Impala, Grand Prix, Century, Regal, LeSabre and Intrigue of those years.
Inside the input housing, two sprags sit one above the other. The lower one is the input, or low, sprag: it locks so the input clutch can drive the input sun gear in first, then freewheels when the second clutch applies on the 1-2 upshift. The upper one belongs to the third clutch and does its work in third before overrunning on the 3-4 upshift. Each sprag is a cage of angled wedges that bite between an inner and outer race in one direction only, so the condition of the wedges and both races decides whether the gear holds.
The C version covers the later run of the stacked-sprag design. GM dropped sprags altogether for 2003 4T65E production and went to pawl-type one-way clutches, so 2002 is the last year this part applies.
One caution: input clutch piston seal leaks on the 4T65E can also cause a no-first-gear complaint, so do not assume the sprag until the housing has been air checked.
Verify fluid level hot, scan for codes and look at the pan. Rule out a sticking pressure control solenoid with our EPC solenoid guide, and if the complaint is a slow shift into Drive, follow the delayed engagement guide. The common problems guide covers reading slip by gear. On the bench, hold the outer race and turn the input sun gear: free one way, locked the other. Then air check the input and third clutch pistons before you blame the sprag alone.
Listed for 4T60E and 4T65E transaxles from 1996 through 2002. That is the 1996 4T60E and every 4T65E from the 1997 introduction until the 2003 change to pawl clutches. The 1993-95 4T60E uses the earlier A84658B assembly, and 2003-up units use a different set entirely, so match A84658C, compare the old assembly's height and element count, or send us your year and VIN. A 32-tooth input friction confirms the sprag-era input housing. Browse the full 4T65E parts collection for the rest of the job.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
Both are input and third clutch dual sprag assemblies. A84658B is listed for 1993-95 4T60E units, and A84658C for 1996 4T60E and 1997-2002 4T65E units. Match the number or compare your old assembly before ordering.
No. GM changed the 4T65E to pawl-type one-way clutches at the start of 2003 production, and the parts do not interchange. Use the 2003-up input and third set for those years.
Yes. Leaking input clutch piston seals can also leave you with no first gear in Drive. Air check the input clutch before replacing the sprag, and replace the seals during any rebuild.
New input and third clutch frictions, steels and seals, plus a new filter and pan gasket. Inspect the races, input sun gear and input housing for cracks while it is apart.
Use Dexron VI. GM lists about 7.4 quarts for a 4T65E pan service on the 2008 Impala; a full rebuild with a drained converter needs more. Check the level hot.
