There are dowel pins on each side of the block, that the transmission goes on to. You might try spraying some WD-40 between the block and bellhousing. You might try using a pry bar, or moving the transmission up and down to get it to break lose from the block.

Do u have to loosen torque convertor to remove the engine on a 5.2 and if so how?


The torque converter is connected to the flex plate by 4 or 5 bolts. There is an access plate or hole at the bottom of the bellhousing. So yes, you will need to rotate the engine by hand to access these bolts one at a time to remove them. Remove all the plugs from the engine put a half inch ratchet on the bolt on the front of the crankshaft and rotate the crank to position the bolts on the torque converter.

I have removed every bolt i can find and still cannot get the tranny seperated from the motor.


You did remove the starter, didn't you? If all of the bell housing to engine block bolts have been removed, then maybe the dowels between the two faces are just tight and have to be shaken or jarred loose. There should be probably 2 metal dowels (about 1/2 inch long) spaced around the bolt pattern, used to help hold the tranny in alignment with the block and the bolt holes. Rust or corrosion can make them pretty tight over a long period of time. You will see them after it is separated. Pry on it a little, jar it, take a hammer to it ! Then look for a bolt you missed if it don't separate !

Instructions on how to change out a transmission


You'll need to remove the starter, the inspection cover, remove the three bolts going thru the flywheel into the torque converter. Disconnect the driveshaft, support the transmission and remove the transmission mount and crossmember. Disconnect the downshift linkage, any electrical plugs, transmission cooling lines and the shifter linkage. Lower the transmission to get access to the 6 bellhousing bolts, becareful that you don't lower it too far, because of the distributor at the back of the engine. Remove the 6 bellhousing bolts and it should be ready to come out.

I need to seperate the engine and tranny on a 99 4x4 Dakota 3.9l. Seems to be a plate blocking access. Need to get to the torque converter bolts.


there is an inspection cover on the bottom of the bell housing you must remove to get to the torque converter bolts. you must rotate the fly wheel to access all the bolts. they make a tools for this, but a flat head screw driver works just as good, it just takes a little longer.

Engine removal 1997 monte carlo


For the torque converter bolts you will need to remove the starter and then you can spin the engine over till you see the bolts there will be three of them If I recall right they are 18mm headed bolts.
When I remove an engine I like to leave the top two bolts in the transmission to engine bellhousing. Then when you get the jack right under the transmisson and get your engine hoist all hooked up and ready to pull it they are right there and easy to unbolt rather than sliding under the car to try and get the last bolt out. There is no specific way to remove them, I just find that alot easier!

Need instructions for installing a 1994 ford tauras 3.0 transmission


have a shop do it? but if you absolutely need to do it yourself.

lift vehicle at least 30 inches off the ground and remove front wheels. detach balljoints and use engine support system to ensure engine does not change position. it will be necessary to use a system that is positioned over the engine rather than under.

remove the subframe from beneith the car. it should have 4 bolts and some minor brackets connecting it to the transmission.

remove electrical and linkage connections from transmission.

remove half axles

remove lower bellhousing cover. disconnect torque convert to flywheel bolts.

remove bellhousing bolts while transmission is supported and seperate from engine.

to install reverse proceedure.

if these directions are not sufficient for you then i would recommend spending the 20 bucks on a manual you cheap skate.
