IDENTIFICATIONTransaxle may be identified by a group of letters and numbers stamped an a pad on top of transaxle. First 2 letters are transaxle type. Next 7 numbers are transaxle serial number.

DESCRIPTIONThe Honda 3-speed automatic transaxle is a combination of a 3-phase torque converter, dual shift transaxle and a differential-type final drive assembly. Transaxle consists of a mainshaft and a countershaft. Transaxle is controlled by the main valve body, regulator valve body and the servo valve. Countershaft is in constant mesh with the differential ring gear.

Pull steering knuckle outward until axle shaft is clear of front hub. 3. Pry Constant Velocity (CV) joint out of transaxle case approximately 1/2" (12 mm), this will collapse spring clip (on axle shaft inside transaxle case) and allow axle shaft to be withdrawn from case. 4. Pull axle shaft out of transaxle case and out of front hub assembly, Repeat procedures for other axle shaft.Disassembly
