Gear oil change question

I'm planning to change my tranny fluid soon using the following procedure:

Lotus Elise Maintenance, Drain and Refill Gearbox Oil

The instructions say to pump in gear oil until it starts to drip out. Is the assumption that the car is level on jack stands? How sensitive is exact level of the the gear oil? If I only have the rear of the car on Rhino ramps, will this procedure still give the right level of gear oil?

Thanks,
Mike

You want to level it out as much as possible. Put stands on the front and rear. It's not much more work to get it done right.

I got really good shifting:

5. The best transmission lube Iíve found is Redline MT-90 plus a little Power Punch Extreme Gear Oil Additive. (Note that it takes two changes to get rid of the previous lube.)

a) Early cars have wobbly shift towers. Look up Stanís Mod (bolt and spacer; http://www.billswebspace.com/ShifterReinforcement.pdf) and

Re-Enforcer long thru bolts that terminate under car and tie down the tower:

These (lube, mods) make a huge change in shifting.

I've changed the transmission oil twice now. Each time I had the rear on ramps but also the driveway had roughly the right slope so that the engine was level. Perhaps your driveway has a slope too?

I don't believe it's that important. Been driving 5 decades....

I will admit I am one of the OCD people that jacks up the car up front to be level for such things, but it probably doesn't matter, I can imagine the difference in fluid only being a few milliliters... Maybe on transmissions that are known to be sensitive to oil levels (I don't think ours is).
