Hey guys

Contemplating removing my auto transmission from my 4wd mighty max on the garage floor rather then finding hoist time.

Who has done it and how much of a pain in the ass is it??

Any tips or tricks??

Take out trans and t case as one?

Thanks

Mike

I have. It's a pain in the butt, more so one handed. If you are alone, go on northern handyman or the like and find one of those tranny jack adapters, that installs on you floor jack in place of the normal lift cup. Two can do it without the adapter, but you need the jack.

I think it's too heavy and tippy with the tcase attached. It comes off easy, one man.

Buy two extra bolts like the outer bellhousing bolts, except about an inch longer. Cur off the heads and use them as guide pins to align the engine/tranny on removal/install, mostly the latter. Lots of extensions and wobble sockets will reach the upper BH bolts. Remove the torque converter with the tranny, and remove it to the side as soom as the tranny is out, or you'll warp the tranny front seal. One very important trick. The converter has to sock in in three stages when you stick it back in the tranny, and ends up a tad over an inch behind the bellhousing flange. The three stages are two spline engagements, on one where the two slots on the backmost end of the converter slig over the two inward tangs of the tranny oil pump inner gear. Be camn sure you get it right. Too short and you break the cast iron oil pump gear, pieces of which then tour the valve body.

Hey thanks for all the tips, i really like the one about the bolts for line up pins.

a few other questions, what do you do with the manual shift lever for the t case?

also the trans i am putting in is from a v6 montero how hard is it to swap bell housings? will there be gears and springs flying out or is every thing contained in the main housing?


thanks again

mike
