When I did my tranny... valve body only... I used rhino ramps under front wheels... and used two old 2.5 ton steel jack to raise rear end only for filling up tranny.

Good deals on jacks are Costco, Sam's... BJ don't carry them. Costco has aluminum good one if you can get em. So damn light! And fast going up (double pumps)... Good control down on the aluminum jack.
