    I am getting ready to remove my 700r4. There are 3 bolts i can see holding the torque converter to the flywheel. Do I need to remove these or dose the converter stay on the flywheel?

    Remove the bolts, the converter comes out with the tranny.

    Take a pry bar on the flywheel or a 5/8's socket on the front balancer bolt and rotate the engine until you can reach the bolt.

    are you pulling this out of a blazer? if so, it's easiest to remove the transmission tunnel and then put a cherry picker in there to lower it down. this allows you movement in any direction to get it away from the block. also, it makes access to the top bellhousing bolts much easier. it will also help to support the weight of the engine w/ a floor jack and a piece of lumber under the oil pan.

    Are the tunnels removable in all years blazers or just certain ones? When I say removable, I mean by bolts, not by blue tip wrench.

    I'm going to be faced with a tranny removal soon so I figured I'd ask.

    i know for sure that it is for the '83 model year, which has the same body style as your 88, so i'd assume it wouldn't be a problem for you. easy way to check, if you don't want to pull your carpet up, would be to just get under your rig and look for the threaded part of a bolt coming through the floor where the tranny hump meets the floor pan.

    My 88 doesn't appear to unbolt either. It does look like it wouldnt be too hard to remove and replace and make it a bolt up item... the floor does look to be two peices but on mine it looks like its glued together...
