Transaxle Failure

I think cleaning the MAF is more important than cleaning the TB. I've already covered MAF sensor cleaning

 

Up to a point, soot on the throttle butterfly is just un-aesthetic. When it begins to interfere with motor control of the butterfly angle, then we need to get in there.

More praise for dpf for this thread and his brave mechanical worl!

Yes, of course. The Toyota MAF is very easy to remove and clean. For most on this forum, tackling the TB is a lot harder. I would expect a lot of folks to spray in way too much TB cleaner, and wind up with a no-start condition

dailyphotofix, where did you buy the transaxle oil pump? I have a VW and I'm looking to get myself a pump because I need to change my transmission oil as well. I can't help but to notice the pump fits the bottle of oil, did it come with the oils? Thanks.

 

I've seen those pumps at marine supply places. They're used to pump gear lube into the lower unit of an outboard or stern drive

 

Marine supply places are good for oil transfer pumps, as jayman says. Watch out for the cheapest West Marine model. The price is right, but it will only work for one season.

IMO its easier to use a funnel with a three ft long flexible tail, instead of having to pump the ATF into the fill hole.

 

+1 A funnel with a vinyl tube works well.

 

It so happen that your pump fit your oil bottle? what if I were to buy my pump and it doesn't fit the bottle? If it came with a bottle, the problem solved. wait, did you have to twist the pump tight against the atf bottle or did you just let it hang? is an air tight seal required?

Thanks,

 

That way the folks at the marine store get to see you every season

 

They're designed to fit onto quart bottles and I haven't had any problems yet. They don't need an air tight seal.

 

If you visit your local discount auto parts store, you should be able to buy either of two lubricant pumps. One will fit the narrow neck bottle that is typically used for quart bottles. The other will fit the larger neck bottle typically used for gallon bottles.

The Toyota ATF WS bottle is tricky because it is quart-sized but it has a large neck, therefore you will need the pump usually used for gallon bottles. Bring a bottle with you when shopping for a pump, if you have any doubt. You need to tighten the pump cap to make a tight seal with the bottle and to avoid spilling ATF everywhere.

I used a pump when changing transaxle and MGR fluid on my HiHy, because it was not feasible to use a funnel for that vehicle.

 

You haven't fully lived until you've had ATF run down your arm, into your armpit. It's a feeling I can't even remotely describe

 

Better still, put it on Ebay:

"Busted NHW20 Transaxle" - "The notorious broken transaxle recently removed from a Prius as described in PriusChat. Buyer pays for shipping, 300 lbs pickup near Bear Lake CA. Very, very broke and unusable but a great conversation piece or decrative table top piece for a gear-head. Alternatively, it could be mounted by a hybrid skeptic for their trophy case or disassembled to reclaim the significant scrap metal: copper, aluminum, steel and rare earth magnets."
