Disconnecting A340e

I've searched the TRSM and the forum but haven't found what I'm looking for. I pulled my engine today with the tranny attached. My question is, where do I go to unbolt the torque converter? I can't see a place to expose it. I'm used to older GM's that have a dust cover that you can remove and expose the converter. I admit I did not look at it too long since it was getting dark and the mosquitos were invading. Suggestion or advice. No I'm not swapping to a 5-speed. I've got my hands way full as it is.

The dust plate on the bottom is held on by 4 screws I believe. Take those out and loosen the rest of the tranny bolts and you should be able to slide the plate down and get to the bolts.

No need to unbolt the converter, just unbolt the tranny from the motor and the tranny will slide off and leave the torque converter attached to the flexplate. Then it is a snap to unbolt the converter.

The flexplate is bolted to the block. That's why you have to unbolt it from the torque converter.

right, but the converter itself just slides on and off the tranny shaft.

So just remove all the bolts and slide it off like a manual tranny? That easy huh?

Just unbolt the bell housing from the block, slide the tranny off, then unbolt the converter. Much easier that way. Remember the converter will have fluid in it

Ohhhh yea, I forgot when I unbolted one, the engine and tranny were still in the car. I'm retarded :nono:

yep that easy. actually a little easier since you dont have to screw around w/ clips and clutch fork. the hardest part about the whole deal is getting to the top bellhousing bolts. if you jack up the back of the tranny to tip the motor forward a little it helps. and like jdub said, a ton of fluid in the converter. more than the rest of the tranny! btw, now would be a good time to pick up one of suprarich's converters

Anyone know what material the Pump gear is in the front of the trans?

Reason I ask is there have been a few pump failures here from people installing the trans without properly engaging ALL of the splines and the Pump Drive dogs so I suspect it's Sintered and prone to fracturing.

The reason I bring this up is I'd hesitate to leave the Convertor bolted to the drive plate in case the Tranny hangs up for some reason pulling it out and breaks the pump.

May not ever happen but it's a concern to me.

I always unbolt the convertor and then the tranny housing bolts.
Safer that way.
I heard that too...incorrectly installed convertor breaks the pump.
I checked my convertor several times before I bolted everything up.
