H6 Applications

• 5 shafts • Input shaft, Main Shaft, Secondary Shaft, Third Shaft, Idler Shaft • Gears on the shafts are in constant mesh with the gears on the countershaft (Output Shaft) • 6 Clutches, 1 One Way Clutch • Valve body consists of: Main Valve Body, Regulator Valve Body, Secondary valve body, Manual valve body and the stator support • Solenoids: 4 PWM solenoids (CPC A/B/C/D), 3 ON/OFF solenoids (A/B/ Line pressure) (The first Honda to utilize a line pressure solenoid)

Introduction

Introduction • CPC solenoids Directly control the clutch shift feel/apply.

This unit does not use CPC valve like other Honda’s • Line pressure solenoid is a pressure reduction solenoid

(Similar to Chrysler) • Pressure Switches: Mounted on the solenoid body, Close

at 36 Psi, Open at 31 Psi • Pressure Switches: A=2ND Clutch, B=3rd Clutch, C=4th

Clutch, D=5th Clutch, E=6th Clutch • Torque Converter consists of: Impeller, turbine, stator,

Multi plate Clutch and the starter ring gear. TCC capable in 1st through 6th gear on accel, 2nd through 6th on decel.

Repair *Take Care not to Damage the 11 Tubes. *All the Tubes are The same size *The end with the O-ring Closest to the end, faces OUTWARD *Tubes have Screens In the ends, Keep the Screens Clean

Tubes

Repair Some LEFT HAND nuts are Used, Be Careful Washers mounted under The nut has an X on it The X faces the Nut

Repair

Some washers are STEPPED The Baffle extends under All the gear sets

Repair SHAFT REMOVAL Step one — Remove the second gear from the countershaft. Step two— Remove the mainshaft. Step three — Remove the third shaft. Step four — Remove the 2nd and 5th clutch drum from the secondary shaft . Now all that’s left to do is grab the secondary shaft and countershaft and out of the case they come, along with the idler gear shaft. All the shafts are out of the case, with no strained muscles or busted knuckles.

Repair

Do not pull The bearing By pulling on The gear

Repair

Use a bearing splitter To pull the bearing

Repair

Do not pull the gear And press fit sleeve By pulling on the gear Use a puller to pull the Sleeve from the Shaft. The gear will Then slide off.

Repair Remove the shafts When removing the Components from the Shafts, some will Require you to use a Hydraulic press

Repair

The TAPER on the Reverse Collar Should Face the 4th gear

1st, 5th, TCC and Line require no special tools

other than an adapter to hook to your gauge

3rd and 6th gears are “Allen” head bolts

mounted to the solenoid block

2nd and 4th require your gauge to be “Tee’d into

the pressure switch ports for that circuit
