    Well my friend / mechanic has not come by to remove the 455 out of the rivi. We picked up the engine hoist and i have a. Liftplate and engine stand ready. The starter has been removed, the compressor, etc the mount bolts are out too. Well hes taking his sweet time while i need this car for school so i am going to pull the engine myself.
    I have to double check for ground straps.
    Here is what im not sure of. Before unbolting the transmission i will have.to leave a jack. Under it to hold it up right? And another thing is that the car is in my driveway at.slight uphill angle. I have blocks behind the wheels. It should be a simple pull right? The torque converter will stay on and the flywheel also?

    The transmission is staying in the car? You need to unbolt the torque converter and push it back away from the flexplate. Otherwise you'll have an EPA disaster on your hands! The flexplate stays on as you can't remove it with the trans in the way.

    Having the car not on level ground is not good, but I guess it could be done if its just a slight grade:Do No: .

    really be carefull with that car on a incline.... be sure to use jack stands and get the weight of the car on them so it will not move,,,,, then vigorously shake the car before you get under it to be sure it wont fall on you.... a car doesn't fall on you but once,,,, then there is slow walking and sad singing followed by some spade work.... First, mark and remove the hood.... then,
    remove the radiator/fan shroud/fan,,,unbolt the motor mounts, all the lines to the engine,,, wires,fuel line, alternator/ power steering with those brackets...and the starter and the exhaust pipes from the exhaust manifolds.... then remove the inspection cover from the bottom of the bell housing and unbolt the torque converter from the flex plate,,, there should be 4 bolts ....then remove the bolts from around the bell housing,,, next put a floor jack under the trans oil pan with a 2x4 block between the pan and the jack... and put a little pressure on the pan to hold the trans up just a little.... hook the engine lift to the engine and pick it up and then gently rock it to make it come loose from the bell housing...,it will lift up about 6 or so inches and then you should be able to take it out....

    PLEASE!!!!!! Securely apply the parking brake!!!!!!! Take the trans. out of park to make sure the e-brake holds while slowly removing your foot from the brake pedal.

    If your friend isnt going to help you, find someone else to lend a hand that has done this before. Pulling an engine for the first time IS NOT a do it yourself job, get some experienced help to do it along with you:TU:

    Not a simple pull by any means. Any incline at all, and as soon as the engine hoist is holding the weight of the motor, it (the hoist) is going to want to roll downhill. The higher you have the engine, the more the hoist will want to tip over. Sounds like a recipe for disaster to me. Level ground is a must with a hoist.

    before you unbolt the trans from the block....
    remove the inspection cover
    remove the 3 bolts holding the converter to the flywheel

    as mentioned above push the converter in tight to the transmission.

    Now unbolt the trans

    If the converter comes out you will spill fluid.
    Then when you put it back in, you need someone experienced to engage it properly and to know when its fully seated. if not, its bye bye trans - ask me how I know... live and learn..

    That's a lot of weight to be swinging on the end of an engine hoist.....by yourself......on an incline.
    Like a previous post mentioned not for a first time job.

    Thanks for the replies, I didn't think about the hoist tipping, I'd rather wait in that case. I figured I had to make sure the converter didn't fall but I wasn't sure how, seems simple enough. If I could, i'd do this inside the garage but the car is out on the drive way, on the opposite side.

    By the way, does anyone know what size bolts hold the engine to an engine stand? I can measure just seeing if anyone knows of the top of their head so I can pick some up on the way back from school.

    Thanks!

    I believe they are 3/8" (hopefully someone else can confirm)

    If its a regular engine stand like this they need to be 2 1/2 or 2 3/4 long
    Get a good washer for them too.

    Good call. My worries exactly. Even if it didnt tip over, rolling that thing uphill away from the Riv with an engine swinging from it would be murder.

    use grade 8 hardware when you hang that thing on the stand....

    be sure to get Grade 8 bolts. Dont trust the weight of that motor to cheap bolts that could shear or snap.

    when i pulled the engine in my gs, we used a chain fall and three of us guided the engine out with the tranny attached.
    when we removed the engine from my brother's camaro using an engine hoist, it took three people - one to hold & manage the engine hoist and two to guide the engine + tranny, out.

    You've gotten good info on the procedure for removal, but I have
    a couple of thoughts. First off, unless you *don't* have a garage,
    I would get that car in the garage to do this - you want a nice,
    level surface to pull the engine - it's enough of a battle without
    having to deal with an inclined surface.

    Secondly, it is *way* easier to just pull the tranny with the engine.
    Why? cause it's more difficult to stab the tranny/bolt the torque
    converter back on - it's way easier to do all that with both the
    engine and tranny out of the car.

    What year Camaro? On mine (and others I've worked on - 4th gens),
    we take the engine out the bottom with the subframe - i.e., you lift
    the car up and pull the engine/tranny straight out :)

    Sorry for going a bit off-topic here.
