The correct way to bleed the clutch hydraulics Question..
Whats the best way to bleed the hydraulics?
I was told to pump 5 or so times.. on the 5th pump crack the bleeder valve, let some fluid out.. Close and pull the pedal up.. Then check the fluid.. Does that sound right? And the pedal isn't supposed to come up on it's own correct, after cracking the valve and closing it that is..?
Thanks

Sounds mostly correct.
Pump pedal, open bleeder, close bleeder, pull pedal back up, repeat.
However, you need to be careful when pumping the pedal. If you pump it too quickly or abruptly, you can cause any air pockets to break up and separate, making the bleeding process take even longer.
Pumping it is good, but go easy and try not to let the pedal pop back up with full force.

This bulletin is being revised to add model years. Please discard Corporate Bulletin Number 01-07-31-002A (Section 07 - Transmission/Transaxle). This bulletin is being issued to inform dealers of an improved procedure to aid in the ease of bleeding the clutch hydraulic system for the above listed vehicles. This procedure can be used anytime air is introduced into the hydraulic system. Following this procedure may also reduce the number of unnecessary parts replaced for low clutch pedal reserve and high shift effort.
Verify that all the lines and fittings are dry and secure.
Clean the dirt and grease from the reservoir cap in order to ensure that no foreign substances enter the system.
Remove the reservoir cap.
Fill the reservoir to the proper level with the required fluid.
Attach the J 43485 (Adapter) to the J 35555 (Mity Vac), or equivalent.
Brake fluid will deteriorate the rubber on J 43485. Use a clean shop cloth to wipe away the fluid after each use.
Place and hold the adapter on the reservoir filler neck to ensure a tight fit. In some cases, the adapter will fit into the reservoir opening.
Apply a vacuum of 51-68 kPa (15-20 hg) and remove the adapter.
Refill the reservoir to the proper level.
Repeat Steps 6 and 7.
If needed, refill the reservoir and continue to pull a vacuum until no more bubbles can be seen in the reservoir or until the fluid level no longer drops.
The vehicle will move if started in gear before the Actuator Cylinder is refilled and operational. Start the vehicle the first time in neutral to help prevent personal injury from vehicle movement and see if the transmission will shift easily into gear.
Pump the clutch pedal until firm (to refill actuator cylinder).
Add additional fluid if needed.
Test drive vehicle to ensure proper operation.
