I dunno, maybe I'm weird, or I've got a more handy fluid pump than y'all do. Here's how I do mine:
1. Put car up on ramps.
2. Remove drain plug to drain oil fluid.
3. Replace drain plug, remove fill plug.
4. Pump in fluid 'till it runs out.
5. Quickly replace fill plug.
Seems a lot easier than...
1. Put car up on ramps.
2. Remove shift knob.
3. Remove shift boot trim and boot.
4. Remove shifter.
5. Scrape off old RTV silicone sealant.
6. Crawl under car and remove drain plug to drain old fluid.
7. Replace drain plug, crawl out from under car.
8. Pour in new fluid.
9. Reapply bead of RTV silicone sealant to shifter base.
10. Reinstall shifter.
11. Reinstall shifter boot/trim.
12. Reinstall shift knob.
I mean, either way, you've gotta crawl under there to remove the drain plug, so why not refill it while you're still under there...?
I use a groovy little fluid pump I scored at Checker Auto for less than $10 (Valvoline brand). Kinda like the above mentioned one, it screws onto the top of a gear lube bottle, and you pump the thing on top until you run outta fluid. Take the remaining last few drops, pour it into the next quart before putting the pump onto that one, and repeat. Takes me about 30 minutes total, and only one time crawling under my car.
