4T65E Pump 1997-01, remanufactured and ready to install. Fits the 4T65E. Ships fast from the USA.
This listing carries a pump title, but the part is a remanufactured first-design 4T65E valve body supplied with its oil pump and the oil pump shaft sleeve, reference number 84740GD. It is catalogued as the Volvo version of the 1997-2001 unit, with a Holley-built pressure control (EPC) solenoid and a 90-degree corner on the casting, and the listing names the Volvo S80 and XC90 as possible applications. If your 4T65E-equipped Volvo is slow into gear when warm, flares between shifts, has stored P1811 or will not lock the converter, and a pressure test points at the pump or valve body, this assembly replaces both in one job.
In the 4T65E the pump is a slide-type vane pump that bolts to the valve body and channel plate under the side cover, turned by a pump shaft from the converter. On first-design units the rotor support sleeve lived in the valve body rather than the pump, which is why this assembly comes as a matched set with the sleeve. The pump creates all the oil; the valve body regulates it. The computer pulses the EPC solenoid to set line pressure, the shift solenoids select the gear, and the AFL valve in the channel plate limits feed to those solenoids. Transmission Digest reported that in June 2002 GM went to a three-piece pump, moved the sleeve into the pump, changed bolt lengths and shrank the pressure switch and PC solenoid, and that first- and second-design parts do not interchange. The Holley EPC on this unit marks it as first design; the later 2003-up Volvo kits are listed with a Bosch EPC.
Check the fluid hot and look at what is in the pan. A level problem makes a good pump whine, and heavy friction material means the clutches are already gone and a valve body alone will not save it. Run a hot line pressure test several times. Low idle pressure that stays low points at the pump; good idle pressure that will not rise points at the EPC solenoid, boost valve or AFL bore. Our 4T65E delayed engagement guide and 4T65E common problems guide walk through the order of tests.
This is listed for 4T65E units from the 1997-2001 first-design years, in the Volvo configuration. Volvo ran the 4T65E with its own TipTronic-style manual shift control, and this valve body is catalogued separately from the Buick and Chevrolet units, so GM owners should not order it on the strength of the transmission name alone. The XC90 named in the listing arrived after the June 2002 design change, so XC90 owners in particular should compare the casting, the EPC solenoid and the pressure switch with their old unit, or send us the year and VIN before ordering. GM 1997-2001 cars that only need a pump should look at our 1997-2001 4T65E pump with rotor support, and the rest of the early parts are on the 4T65E collection page.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
No. It is a remanufactured first-design 4T65E valve body supplied with the pump and the oil pump shaft sleeve, reference 84740GD. The pump title on the listing undersells it.
It is catalogued for the Volvo version of the 1997-2001 4T65E. GM car owners should not assume fitment; send us your year and VIN, or use our 1997-2001 4T65E pump if the pump is all you need.
It identifies the pressure control solenoid fitted to the valve body. First-design units in this family use the Holley-built EPC; the later 2003-up Volvo kits are listed with a Bosch EPC. It is one of the details to match against your old unit.
A new filter and pan gasket, a side cover gasket, and fresh fluid. If the fluid showed friction material, plan on a clutch rebuild as well, because a new valve body cannot fix burned clutches or a broken band.
Yes. Reset the transmission adaptive values with a scan tool or the method in your service manual so the computer relearns shift timing on the new hydraulics.
