Frictions, steels, oil filter, and a complete gasket and seal set to rebuild the SLXA and BMXA four-speed automatic in the 2001-2005 Honda Civic 1.7L.
The seventh-generation Civic sold in huge numbers, and a lot of the 2001-2005 cars with the 1.7L engine and the four-speed automatic are now past the mileage where the transmission gives up. The usual story is a slip or flare on the 2-3 shift, a bang into gear after a long pause, a shudder at light throttle, or a car that revs but barely moves once it warms up. If the fluid comes out dark and smells burnt, the clutches are worn through and the unit has to come apart. This master rebuild kit carries the friction plates, steel plates, oil filter and a complete gasket and seal set for that rebuild of the BMXA/SLXA automatic.
Honda's conventional automatics of this era are built differently from most four-speeds. Instead of planetary gearsets and bands, the BMXA uses parallel shafts with a separate hydraulic clutch for each forward gear, so a shift is one clutch releasing while the next one applies. Honda lists the 2001 Civic four-speed ratios as 2.722 first, 1.469 second, 0.975 third and 0.674 fourth, with a 1.955 reverse, and a lock-up torque converter. Because each gear depends on one clutch pack, a burnt pack shows up as a slip in that particular gear, and a hard or leaking seal shows up as a late, soft shift. The kit renews every friction and steel and reseals the pump, axle seals and internal sealing rings, so the whole unit starts fresh instead of fixing one gear and waiting for the next to go.
Start with the fluid. A low level or the wrong fluid can cause harsh shifts on its own, so check the level hot on the dipstick and look at the color and smell. Read any stored codes, since a shift solenoid or sensor fault can mimic worn clutches. If the fluid is burnt and the slip follows a gear, the clutches are worn out. A shudder at steady cruise points more toward the converter lock-up, and our guide on converter clutch shudder walks through how to tell the difference. If you are weighing a used unit against a rebuild, read our rebuild versus replacement cost breakdown first.
This kit is listed for the 2001-2005 Honda Civic with the 1.7L D17 engine and the four-speed automatic, coded BMXA or SLXA (the listing also references ES5). That covers the DX, LX and EX sedans and coupes with the automatic. Honda's 2001 press material shows the HX coupe was offered with a CVT instead of the four-speed, and the CVT was also added to the natural gas GX that year, so an HX or GX with a CVT does not take this kit. Check the code stamped on your transmission case before you order, or send us your year and VIN and we will confirm it. More overhaul sets are in our rebuild kits category.
Use Honda ATF for the soak and the fill. Honda's original ATF-Z1 has been superseded by Honda ATF DW-1, and a multi-vehicle fluid is not a good substitute in this unit. Soak the frictions in fresh fluid before assembly. Replace every seal and O-ring as you rebuild each clutch, and air-check each one before the case halves go together. Measure clutch clearances against the service manual using the selective plates. Hold small seals and thrust washers in place with an assembly gel such as TransJel, then torque the case bolts in sequence. The kit does not include the shafts, gears, valve body or torque converter, so inspect bearings, the pump and the converter before reuse. Flush the cooler lines, set the fluid level hot, and give the computer a few drive cycles to adapt; our adaptive relearn guide explains what to expect.

Only if it has the four-speed automatic. Honda offered the HX coupe with a CVT as its automatic option, and this kit does not fit the CVT. Check the code on the transmission case first.
Friction plates, steel plates, the transmission oil filter and a complete gasket and seal set, including the pump and axle seals and the internal sealing rings. Hard parts, the valve body and the torque converter are not included.
Honda ATF DW-1, which replaced the original ATF-Z1. Use it to soak the frictions and to fill the unit, and set the level hot on the dipstick.
Yes, if the converter passes inspection and there was no heavy debris. If the old clutches burnt up badly, friction material may be packed inside the converter, so many rebuilders replace or reman it at the same time.
It can be worn clutches or the converter lock-up clutch. If the fluid is clean and the shudder only happens at steady cruise, look at the converter and fluid condition before a full rebuild.
Yes. All three used the same 1.7L engine and the BMXA/SLXA four-speed automatic in 2001-2005. Confirm the code on your case if the car has had a transmission swap.
