4L30E Solenoid Kit 2000, new and ready to install. Fits the 4L30E. Ships fast from the USA.
If your 2000 Isuzu Rodeo, Trooper, Amigo, VehiCROSS, Honda Passport, Acura SLX or Cadillac Catera has started shifting late, banging into gear, dropping into a fixed-gear failsafe or flashing the check-trans light, the electrical side of the 4L30E is the first place to look. This kit replaces the solenoids on the 4L30E valve body in one job: the five pieces pictured include the tan-connector shift solenoids, the long cylindrical pressure control force motor and the black-body torque converter clutch (TCC) solenoid. Doing all of them while the pan is off costs less than dropping it twice.
The 4L30E is a four-speed, rear-drive automatic that GM built in Strasbourg, France for BMW, Opel, Isuzu, Honda and Cadillac. It has no throttle cable or governor deciding shift points; the transmission control module does all of it through these solenoids. Shift solenoids A and B are on/off valves, and the combination of the two being on or off selects first through fourth. The force motor is a variable solenoid that sets line pressure, so it decides how firmly every clutch applies. The TCC solenoid sends signal oil to the converter clutch valve to lock the converter in the upper gears.
On the 4L30E the TCC solenoid also matters in reverse. Transmission Digest's TASC Force notes that TCC signal oil acts on the reverse-lockout valve so the unit cannot go into reverse with the converter applied. A TCC solenoid that leaks feed oil into its signal circuit can cause slipping or neutraling in reverse, especially on cold mornings.
Pull codes first, then check the solenoids at the transmission connector with a meter. Each coil should read inside its service manual resistance range and show no short to the case. Our guide on testing a transmission solenoid with a multimeter walks through it. Check fluid level and condition too. Burnt fluid with heavy clutch material points to a worn unit, and a rebuild with our 4L30E master rebuild kit is the better fix. If only one circuit is faulted, the single 2000 TCC solenoid or 2000 pressure control solenoid may be all you need.
This kit is listed for the 2000 model year 4L30E. Vehicles that used the 4L30E around 2000 include the Isuzu Rodeo, Trooper, Amigo and VehiCROSS, Honda Passport, Acura SLX, Cadillac Catera and the BMW Z3. The 4L30E changed many times over its run, and the BMW/Opel and Isuzu/Honda/Cadillac versions use different gear sets and housings, so compare the connectors and bodies in our photo with your old solenoids. If you are not sure, send us your year and VIN before ordering and we will check it. Other 4L30E hard parts are in our hard parts section.

It is listed for the 2000 4L30E, which those vehicles used. The 4L30E changed between applications, so compare the connectors and bodies in our photo with your old solenoids, or send us your VIN and we will confirm it.
The five pieces shown in the product photo: the tan-connector shift solenoids, the cylindrical force motor that controls line pressure, and the black-body TCC solenoid.
Yes. TCC signal oil acts on the reverse-lockout valve. A TCC solenoid that leaks into its signal circuit can make reverse slip or neutral, mostly when the transmission is cold.
If the transmission has high miles and you are already dropping the pan, replacing the set saves a second teardown. If only one circuit failed on a low-mileage unit, a single solenoid may be enough.
Refill and check the fluid level hot, clear the codes, then road test through all four gears and converter lockup. Shift quality can take some driving to settle as the control module adapts.
