4L60E Pump 1992-94, new other (see details) and ready to install. Fits the 4L60E. Ships fast from the USA.
The first-generation 4L60E is getting old, and on a 1993 or 1994 C/K 1500 pickup, Suburban, full-size Blazer, S-10, Sonoma, or a 1994 Camaro, Firebird or Corvette, a tired front pump is one of the most common reasons the truck sits in gear for a moment before it moves, flares between shifts, or whines in time with the engine. This OEM 4L60E pump is listed for the 1992-94 units, the original design before GM revised the converter clutch controls.
The 4L60E replaced the hydraulically governed 4L60 (700-R4) with an electronically controlled unit, and its first model year was 1993; a 1992 tag on early parts generally refers to that initial production. The hydraulic heart stayed familiar: a variable-displacement vane pump driven by the converter hub, with a rotor and vanes turning inside a pivoting slide. The pressure regulator valve in the pump cover moves the slide to hold line pressure, while the pressure control solenoid on the valve body tells the regulator how much pressure the computer wants.
On these early units the converter clutch was a simple on/off design. The pump still feeds converter charge oil and houses the converter clutch apply valve, but there was no pulse-width modulated clutch apply yet. That is why year matters on this part: the pump, valve body and wiring were designed together, and mixing generations creates problems.
Read real line pressure with a gauge at idle and under load in drive and reverse. A pump that is low in every range is worn internally; one that is fine at idle but falls off in reverse or at throttle points to the regulator and boost valve. Pull the pan and look as well: heavy metal and a burnt 3-4 pack mean the rest of the unit needs work too. Our guide to 4L60E pump rotor and bushing wear details what to inspect, and 4L60E common problems and fixes covers the failures that mimic a bad pump.
This pump is listed for 1992-94 4L60E transmissions. The 1993 and 1994 units share the same basic design and are generally interchangeable with each other, but they are not drop-in matches for 1995 and later units. In 1995 GM added a PWM converter clutch solenoid, and transmission specialists note that installing an early unit in a 1995-96 vehicle sets converter clutch and 3-2 downshift codes. If your vehicle is a 1995 or newer, do not use this pump; see the 1995-1996 4L60E pump instead. Compare the cover casting, converter hub bore and stator shaft with your old pump, or send us your year and VIN to check. The full lineup is in the 4L60E parts collection.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
It is not the right choice. GM added PWM converter clutch control in 1995, and early 1993-94 parts installed in later vehicles set converter clutch codes. Use the 1995-1996 pump for those years.
The 4L60E's first model year was 1993, and earlier GM trucks used the 4L60 (700-R4), which has a different pump. A 4L60/700-R4 has a throttle valve cable running from the transmission to the throttle body; a 4L60E has no TV cable and is controlled through a large round multi-pin connector. If you are unsure, send us the VIN.
It is listed as new other, meaning a new OEM pump that may not be in original retail packaging. It is covered by a 1-year warranty.
Yes. Dexron VI is backward compatible and is what GM specifies for servicing these older units.
Only if the 3-4 clutches are not already burnt. Low pressure from a worn pump often causes that failure, so check the pack while the unit is apart.
