Can sub-frame be dropped without disassembling engine and transaxel

Hi Carl this should be possible if it don't work out open the two engine mounts on top and lift the motor up a few inches. Regards Jim.

It is a pretty involving process to remove and replace the transmission on a Honda Odyssey and not recommended for the home DIY mechanic. Without a vehicle hoist or lift, it is a daunting task to undertake. This will be a brief description of what may need to be removed. The engine and transmission sits on a sub frame cradle. The engine will need to be held and supported by an engine support bar. The sub frame is then unbolted from the bottom. All things necessary must be removed before the sub frame can come out. For example, the rack and pinion bolts, sway bar, lower front ball joints, front and rear engine mounts, and any and all brackets and hard lines. After the sub frame is completely out, the flywheel bolts will have to be removed from the transmission. The cv-axles will have to be removed along with the transmission fluids being drained. Then the harness/connectors disconnected from the transmission, and then the bolts to the engine and bolts for the transmission mount. With a floorjack, the transmission can then be dropped out from underneath. Installation is the reversal.

Transaxle always comes out the bottom

If your doing both- then drop the sub frame

Drop the entire sub frame-- then work on the parts you need to
repair or whatever

If your doing the engine-- usually the transaxle comes out first

Your going to have trouble supporting it and the drive axles your way

You must remove the air cleaner assembly to get to the plugs. It is still VERY DIFFICULT to get your hand in there unless you have very small hands. The windshield comes nearly all the way down on top of the engine. What I do at the shop is to remove the bolts from the sub-frame and lift the body up and let the sub-frame drop down and basically hang by the suspension struts. This drops the engine assembly away so there is clearance to get your hand in to get to the coils/plugs.

Good luck!

NO.you must remove the transmission from the subframe,or drop the whole drivetrain from underneath(the reverse of factory fitting,this is not recommended as the body is too heavy to move around)

cross member yes you do haveto remove it

Buy a Haynes repair manual it is an extensive job requiring the disassembly of the front suspension and in some cases the disassembling of the sub frame to drop the tranny down I wouldn't recommend the undertaking to the average layman mechanic.

have you smashed the sump ??never seen one leak yet?? sure its not the front or rear end oil seals ??..sounds like you have the sub frame in the way ,evan if you remove this bolt you will not be able to drop the sump without removing or lowering the sub frame assembly as the oil pick up pipe stops you from removing the sump in situe.Its not difficult to drop sub frame just time consuming

The sub frame is also known the engine cradle assembly, if it is damaged get another from a wrecting yard, without allot of special equip and tools you are wasting your time trying to repair the old frame, of course I don't know how badly it is damaged so this could be incorrect.
