4L60E [80-25] Automatic Transmission Solenoid Shift Valve Set for 1-2-3

When shift solenoids A and B wear out or fail electrically, the transmission loses precise hydraulic control over the 1-2 and 2-3 shifts, and no amount of adjustment elsewhere in the valve body will correct that. This set addresses exactly that failure point by supplying both solenoids together - the 1-2 (position A) and the 2-3 (position B) - in a universal style that fits 4L60E, 4L65E, and 4L70E automatic transmission units from 1993 onward.

The set contains two solenoids and nothing else. It does not include friction plates, steel plates, gaskets, seals, Automatic Transmission Filter, or any other components that a full rebuild would require. Technicians ordering for a complete overhaul should verify what their job calls for and source the remaining parts separately. The solenoid count is straightforward: one valve for the 1-2 shift and one for the 2-3 shift, both universal style, ready to install in the positions where the stock valves failed.

Each set is assembled at the REMCO facility by hand, counting and verifying components against the part list before the box is closed. A printed parts list ships inside the box, so the bench technician can confirm piece count on receipt before the teardown begins. REMCO has been working in automatic transmission parts since 1991, and this kind of check-before-it-ships process is standard across the catalog.

Before placing the order, pull the ID tag or casting mark on the unit and confirm it reads 4L60E, 4L65E, or 4L70E. Also confirm the build year is 1993 or later, since solenoid design changed at that point. Ordering against the wrong variant will result in a part that does not fit correctly.

• Restores accurate shift timing on 1-2 and 2-3 upshifts, addressing hesitation, harsh shifts, or stuck-gear faults tied to solenoid failure in 4L60E, 4L65E, and 4L70E units.
• This set does NOT include friction discs, steel plates, Automatic Transmission Filter, gaskets, or any other rebuild components. If your service requires those parts, check your parts list before ordering.
• Two universal-style shift solenoids cover both the A and B positions in a single order, so the technician does not need to source each valve separately from different listings.
• Contents: 2 solenoids total - 1 x 1-2 shift solenoid (position A) and 1 x 2-3 shift solenoid (position B), universal style, 93-UP application. Packaged weight: 0.5 lb.
• Before ordering, confirm the transmission code stamped on the unit matches 4L60E, 4L65E, or 4L70E, and verify the build year falls within the 93-UP solenoid application range.
