no i just has a mechanic put the new tranny in from a swap, he put in the broken torque converter and just put the whole car back together. now im out 350$. i was going to attempt this myself tonite.
 


How bad is the torque converter? If it's torn up inside it might be spewing junk into the valve body.

On th sticky suggestion, I guess we would mention it to Bio?
 
The torque converter has a broken missing weight. so there are only 2 of the 3 on it atm. i havnt even bothered starting the car since the swap. i figure it would be a bad idea. i have a question on holding the engine. i have a 4x4 piece of wood going across the whole engine. do i just need to tie a chain around the engine to the wood to keep the engine from moving? or do i need to lower the engine to unbolt the tranny.
 
I put the 4x4 across, run a chain to both engine pull brackets over the 4x4 and then use some 2x4 or small stock to take the slack out of the chain. The trans comes off after the engine/trans is supported by the 4x4 w/o having to lower the motor at all.
 
So the 4x4 i used snapped and the engine almost hit the ground :O. i resupported it with a cumalong. i just took the cradle off the car. what would be my next step?
 


Stop listening to me if you snapped a 4x4. I've seen a 2x4 used, always use 4x4's myself and can't imagine how you can snap a 4x4 with less than 1,000lbs of weight on it. Were you supporting the motor or the whole car?

What do you mean, what's your next step? I posted pictures and text saying what should be done to lower a motor and swap a converter. Somehow you already did the impossible.

Was this 4x4 older than you? How in the holy hell did you snap a 4x4 when it's supporting a motor/trans?
 
Hey there.. I'm new to this forum and am contemplating getting a 2004 or newer Grand prix. I read the trans removal write-up and it is excellent. I've always owned Fords and they have to have the engine/trans removed as assemblies with the subframe. My question is the transmissions on these cars can be removed without a hoist and the engine can be left in the car?

Thanks.
 


Is there anyway to get the bolt that goes in backwards from engine to trans while it is still in the car? Its the one you show the pic of the impact and long extension. Also the bracket that holds trans to engine i removed the 2 bolts on trans but is it necessary to remove the 2 on the engine also?? Any help would be greatly appreciated as i have the cradle and everything laying on the floor....
 
Why did you drop the cradle>? Pulling it out the top is way easier. Yes you have to unbolt that bracket from the engine and then that will allow you to go threw the passenger wheel well with long extensions and get the bolt out.
