Does the transmission pull straight off the engine?

I'm having trouble separating the transmission from the engine. I've removed all bolts I can see and it is clearly loose. Still I'm unable to slide it back to free it. The car is very low at the front so it needs to slide back and up. Pulling as hard as I can moves the entire drivetrain but the transmission is stil stuck on.

Do I need to mess with the clutch fork?

Hello,

i think that will be difficult, if the nose of the car is down. Would be much easier if the car is leveled.

You need definitely to support engine and transmission to get the transmission out. When you say the hole drivetrain moves, how did you support the engine? From the top via chains?

Try to support the engine and the transmission from the bottom too.

Also recheck if all bolts are loosened.

Regards, Markus

It should just slide right out if everything is disconnected and correctly supported, and all the bolts are out, but it would not be a fun job with the car on an angle as the weight of the gear box and gravity are working against you.

The engine is probably hanging on the trans shaft. The back of the engine must be supported or jacked up a little bit. The engine only has 1 support spot at the very front when the trans is pulled.

When I did the clutch IMS last fall, I made a small bracket to support the engine when the trans was out. You can see the trans is still in place as the bracket needs to keep the engine in a good position.

Get the car level & up on the tallest jack stands you can buy.I have these.They are almost 1m high.
12 Ton Jack Stands
Support the engine with a cross bar from above.If you ask specifically about the engine support bar someone will have a photo. I used the generic Harbor Freight bar .
1000 Lb. Capacity Engine Support Bar
You will need to fabricate some plywood 'pads' for the feet of the bar to rest on.
Make sure the bar takes all the weight of the rear of the engine by winding up the adjusters so the rear of the engine is at least 1/2"(12mm) above it's normal level.
Jack up the trans using a transmission jack or motor cycle jack. The trans is heavy and wobbly so be careful how you secure it.
Take your time and do not force it.
Hope this helps.

I followed the Pelican instructions and used a jack stand to hold the engine up and a floor jack to lift up the transmission.

The trans should slide off without too much difficulty. Be sure that you have all of the bolts removed. Refer to this photo for all of the locations: Boxster Transaxle Bolts

I agree with what has been said. My guess would be you still have a bolt that is not loose/out. In my 2004 there is/was one bolt that went from front to back. If you are looking from the back of the vehicle forward, it was at about 5 o'clock. This is a shorter bolt and was in the opposite direction from the rest. Perhaps you could check this? What year is your Boxster?

Below pic may help. The bolt/position I am talking about is seen clearly in this one...

Hope it helps... My car is still up on jack stands and I can send you more pics if needed...

Thank you all for your help. Thanks to your suggestions I found the missing nut. It was covered in almost a centimetre of gunk from the RMS or IMS cover. After literally digging it out the transmission came out a lot easier . Before I found it I jacked the car level, so I have no Idea if I could have slid it off with the nose pointing down.

Been there, done that.

Now, I'll give you a hot tip about re-installation - be sure that you have the dowels/pins aligned and that there is one on each side or you'll get it to within 3/8" and won't be able to close the gap.

Jon,

Good observation! Boat shoes, Yes. Steel tipped, No...

I know it is not safe but I keep out of the way of things dropping on me while the car is up on Jack stands...

I'm willing to bet his wife won't be happy about the mess he has made of the kitchen floor.
