4L60E Shift Kit 1993-2015, new and ready to install. Fits the 4L60E. Ships fast from the USA.
If you own a 1993-2015 Silverado, Sierra, Tahoe, Yukon, Suburban, S10, Blazer, Camaro or Corvette with the 4L60E and you are tired of lazy 1-2 shifts, a 2-3 shift that flares when the fluid is hot, or a rebuilt transmission that cooked its 3-4 clutches again, this is the part that addresses the cause rather than the symptom. It is a TransGo valve body shift kit covering the entire 1993-2015 production run, so one kit handles the early 1993-95 trucks, the 1996-on units with the revised case connector, and the late 2009-2015 units with bonded separator plates. It is new, carries a 1-year warranty, and ships from the USA.
The 4L60E's computer picks the gear with two shift solenoids and sets line pressure through the pressure control (EPC) solenoid, but the actual quality of each shift is decided by hydraulics: accumulator springs, the pressure regulator and boost valve, checkballs and orifices. GM calibrated those for a soft feel, and the price is long slip time on every apply. A shift kit retunes the accumulation circuits and nudges line pressure up so the 2-4 band and the 3-4 clutch grab cleanly and quickly. The firmer feel is a side effect; the real payoff is less heat in the frictions. TransGo's kit also replaces the TCC regulator and isolator valve, because that bore wears and causes converter clutch slip.
Before you buy, check fluid level and condition and pull codes. A shift solenoid code such as P0753 or P0758, or an EPC code like P0748, is an electrical or solenoid issue first, and a shift kit will not cure it. If the codes are clean, or only point to TCC slip, and the complaint is shift feel, the hydraulics are the likely culprit. Our 4L60E harsh shift causes guide walks through separating a pressure problem from a solenoid or sensor problem, and the 1-2 accumulator and shift feel guide explains why soft or harsh 1-2 shifts so often trace back to the accumulator circuit this kit recalibrates. Burnt fluid and debris in the pan mean the clutches are already damaged; plan a rebuild with the kit, not the kit alone.
This kit is listed for the GM 4L60E from 1993 through 2015, which also covers the 4L65E and 4L70E variants that share the valve body layout. That span crosses several design changes: the early units, the mid-90s case connector change, late-model trucks with active fuel management, and the bonded separator plates used from 2009. TransGo includes TCC regulator valve options for vehicles with or without AFM, so follow the instructions for your exact build. Hybrid applications are not covered. If you are unsure which version you have, send us the year and VIN, or browse the full 4L60E parts collection to compare plates and kits by year.
This is a bench job: drop the pan, pull the filter and valve body, and follow TransGo's instructions in order, keeping removed springs and valves sorted so nothing ends up in the wrong bore. The kit includes drill bits for orifice changes, so read each step before you cut. The best time to install it is during an overhaul with a 4L60E master rebuild kit with filter, since fresh clutches and seals let the new calibration do its job. On a 2009-2015 unit the bonded plate cannot be reused once disturbed, so order the TransGo 46-PLT-09 separator plate and gasket kit with it. Refill with Dexron VI ATF, check the level hot and running, and clear adaptive values with a scan tool so the computer relearns shift pressures. Our TransGo vs Superior shift kit guide covers the install in more detail.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
Yes. It covers 1993-2015 4L60E, 4L65E and 4L70E units. Because late trucks may have active fuel management, use the TCC regulator option the instructions call for on your build. If in doubt, send us your year and VIN.
No. A shift kit corrects hydraulic calibration; it cannot restore burnt clutches or a worn band. If the fluid is dark and smells burnt or the pan has friction material, rebuild the unit and install the kit during the rebuild.
It addresses the most common hydraulic cause, a worn TCC regulator valve bore, by supplying a new regulator and isolator valve with longer lands. Rule out a failed TCC solenoid, wiring problem or worn converter first.
Dexron VI ATF. Check the level with the engine running and the transmission at operating temperature after the install.
Yes. Clear the transmission adaptive values with a capable scan tool and drive the vehicle through normal shifts so the computer relearns pressures with the new calibration.
