Loosen the bellhousing bolts and wiggle the trans while prying. I've met some pretty stubborn couplers, non stood against that trick tho. I only use a large screwdriver also. Sometimes a very minor variance in machining as far as the alignment dowels goes can be a problem. You'll get it. Good luck

My problem was that I had slid the coupler onto to the torque tube and somehow it had jammed. The tranny was still out of the car so it was easy for my just to use a 3 prong gear puller to remove it. The real problem was that since the splines are machine to such a tight tolerance that unless I could pry the coupler off perfectly straight it would not move. Once I used the gear puller though it came off with very little force.

Damn. Thanks for letting me know.
Do you guys think removing the piece of the transmission that is on the rear? If that could be removed easy I could pull the rest of the trans further back, right?
Thanks
Mike

Porsche deffinately did not leave a lot of room. Make sure the bolts are completely out of the coupler. If you are unable to slide it way back onto the transmission input shaft you will not have enough room to get the tranny out.
On my parts car I just used a sawzall and cut out a section of the spre tire bin so I had plenty of room to move the tranny back. Not Something I would recomend on your car though!

I got my old '83 transaxle out by:
1 - taking out all of the rubber bits that cover the holes to get to the coupler bolts
2 - took the bolts COMPLETELY out of the coupler
3 - used a screw driver with a 4 sided shaft so I could put a wrench on it and spread the coupler a little at each end to loosen the grip on the shafts
... and then it slid right back on the transaxle shaft. No problem. This is an '83 with 150K miles on it... doesn't get much older.
THEN I undid the transaxle from the car to get it out.
Today, I am putting my rebuilt transaxle back in... If I run into anything weird, I'll let you know.
Spreading the ends of the couple may have been the key. I learned to take the bolts completely out by removing my steering shaft for an engine swap.
I don't think it should be all that difficult if you follow the above.
Don't unbolt the transaxle from the car until you get the coupler moved.
I wont try to put it back on until the transaxle is back in and bolted up.

The rear of the trans will not come off as you think. There's alot to it, the gear sets and shafts are connected. That and the internal linkage locks them in. On the bench getting things lined up to pull it apart or put it together is a two person job and requires both of them to hold their toungs properly
