Ok, so have the box ready and a ramp lined up. few things I'd like to know if anyone would be willing to give advice.

 

Is there a guide on here which shows removal and re-fitting , cant seem to find one

 

Is there any extra bits I would need? like gaskets? obviously ATF III which I have already.

 

The filling part, im going to assume theres still some oil in it as when I moved it some came out of the end. so what is the best way to drain and re-fill the torque convertor? is there a filler hole for just the torque ? and the total amount of oil is 7.7 litres ?

 

Thanks for all your help ive had recently with my problems with the box, never would have got anywhere if it wasn't for you!

Use this tech to the point of not changing to a manual lol http://www.300zx.co.uk/forums/showthread.php?117000-Auto-to-manual-conversion

 

Auto out to auto in is pretty straight forward, you will need to drain the oil from the old box, remove starter motor and exhaust from down pipe to mid section, remove prop by removing centre bearing bolts and the 4 bolts at he diff, it will then slide out of the box.

on the Z is not that bad. The torque converter needs to be disconnected from the flex plate prior of removing the transmission. The torque converter needs to be removed with the transmission. You can disconnect the converter from the flex plate via the lower transmission shield that goes between the transmission and the engine. Make sure you remove the converter with the transmission. You do not want to leave the converter attached to an engine like you would with the clutch/pressure plate on the 5spd.

Drain the fluid prior and disconnect the cooler lines from the radiator. If you do not drain it, when the drive shaft is removed, and the engine tilted backward, it will create a mess.

Make sure all the electrical connectors are disconnected. Remove the top two bolts first.

If doing this on a flat harbor freight transmission jack, make sure you secure the transmission very well. I do not know about the 5spd transmissions, but the auto transmission likes to slide around on the jack and if it is not secured properly it will slip and fall. Also, you will need another adult person to help you take the transmission off the jack and on the ground.

Installing the torque converter in the bell housing is not that difficult also. Refill the converter with the correct amount of ATF, than slide it on to the input shaft gently. Make sure there is no binding and you will need to hear two clicks.

Reinstalling it will be a pain. Stabbing it will be difficult. It's best to have it sitting leveled on the transmission jack, with the engine leveled also and going straight in. Prior of this remove the dipstick tube so it dose not interfere with the transmission tunnel, it can be installed later. If you have any old tensioner pulley studs, those can be used as guides for the transmission stabbing.
