I did some fruitful research, these are the following viable options: I will be going with option 2 unless I find out there is an LSD in play. TOYOTA GENUINE HYPOID GEAR OIL “SX” API : GL-5 SAE: 85W-90 200L DRUM, 20L PALE CAN 08885-00503 Mineral oil.

Thanks for your reply. Have you changed out the oil in your transfer case or rear differential? Im interested in knowing what oil the community chose to perform the service. For our information: TOYOTA GENUINE HYPOID GEAR OIL “SX” API : GL-5 SAE: 85W-90

Hi All, is there a possibility of limited slip differentials in the 3.0L MNH15W drivetrain? I want to know as I will be replacing the transfer case / rear differential gear oil and need to know if I will need to use an oil that contains a limited slip differential friction additivie.

Hi All, Some lessons learned from the recent transmission oil change at 90,000km with unknown history: Compatible Type-IV ATF fluids with the correct viscosity (7.3 @ 100c) **Caution** None of the lube shops I contacted had the correct fluid in stock, although they assured me it was compatible. The universal fluids (regardless of brand) they had in stock had a viscosity of around 5.5 @ 100c, closer to the ATF-WS used in newer vehicles. They finally looked it up when I started talking numbers and realized they had to special order compatible fluid (JWS 3309 spec) Synthetic: Motul Multi ATF - viscosity of 7.6 @100c ( I chose this) Pennzoil Platinum High Mileage ATF fluid has a viscosity of 7.2 @100c (hard to find in Canada) VALVOLINE IMPORT MULTI-VEHICLE (ATF) FULL SYNTHETIC AUTOMATIC TRANSMISSION FLUID: 6.9 @100c (hard to find in Canada) Non-Synethetic: Mobil™ ATF 3309 (research in forums indicate that this is the exact same manufactor as Toyota branded T-IV fluid; easy to find in Canada but not synthetic). Regarding method: Drain and fill method was selected due to: ease/cost do not trust technicians from lube shop to do a flush (requires disconnection of clamp by ATF oil cooler). the oil pickup filter is a coarse filter which typically shows no buildup at this KM (source: car care nut, licenesed toyota mechianic) therefore dropping pan, replacing filter, scraping old gasket, replacing gasket is not necessary at this point. Other information: The Toyota Type-IV will quickly discolour, not indicating degradtion in performance... however, the synthetic fluids seem to hold their color as reported on internet forums.

Thank you for letting me know. Given how expensive they are, any thoughts on purchasing these used vs new? https://autoparts.beforward.jp/detail/Cooling-Components/Other-A-C-Parts/PA98133944/?buynow=1

Hi all. My first gen hybrid blew up. The 2nd gen hybrid re-appeared in 2011, Im trying to get a sense if they are as problem prone as the 1st gen, or if they are more reliable. Are there many reports of malfunctions? Its hard to tell on this forum as there is no subforums for 2nd gen alphard hybrids. 1) 1st gen had a belt type CVT. I've heard that 2nd gen uses the standard toyota planetary gear type CVT. is that correct? I've seen pictures of 2nd gen CVT teardown which make it look like they have a belt type CVT 2) Are they underpowered? the first gen definately had issues with large hills. 3) 1st gen hybrid battery packs seem to go flat and develop issues in a matter of weeks of non use, such as when you go away on vacation 4) 1st gen inverters seem to be a common problem. Cheers, Mark

Heads up. The used option is an option as well. The inverter themselves are very affordable. Shipping is expensive so look at all options; my exporter can buy this part and ship for about 1/3rd the cost.

My 2003 2.4 Hybrid blew up after a month of use. metal in engine oil. Got it towed to a japanese shop where I saw another Alphard Hybrid of the same generation getting worked on, apparently its transmission failed. Comically, we were on the same stretch of highway for both failures. I wrote mine off, now I own a gen 1 V6 (gen 2s aren't available to use for import yet). So steep incline at motorway speeds killed both our vehicles (120km/h). Id like to try a gen 2 hybrid if I can confirm that they are more reliable.

to be precise. is there any reported issue with the 2AZ-FXE?

I did a bit of research: 1) Entire battery pack: can be bought, with high capacity options thats moves away nimh from overseas. hybrid experienced shop should be able to replace one of these without issue. 2) cell by cell repair: really requires a specialist. looks at voltage of each cell and replaces cells as necessary. ATH10w cells match gen 1 prius cells, and also gen 1 estima hybrid cells. Look to cab companies. THey may have developed this know how in house. Our cab companies use prius vehicles.... replace battery packs 200-300thousand km driven if i recall correctly. Engines at around 4-500k km.

Interesting. I thought that alcohols allowed for higher compression, without actually increasing the octane rating.

Regarding engine braking; yes I used that in the past. I did not know about engine braking issue until literally this week. breakdown occurred last summer, and finally diagnosed a week ago. Engine oil was fresh full synthetic with new denso filter. Notable observations at time of import: visible valves under the oil cap showed darkened / hardened build up; I have never seen this in any of my other previous toyota's (all 5-6 of them), which were generally remarkably clean. one of the valve cover bolts was different in appearance; is that standard? or evidence of previous repair work? fresh off the boat, the vehicle stuttered due to an extremely dirty MAF sensor. problems went away engine seemed "loud", unrecognizable sounds that I attributed to hybrid system when vehicle was apparent. only occured sometimes.

Follow up. My engine is blown. metal shards in oil. game over.

If you read my threads, I suffered an engine failure and no start. Japanese mechanic found evidence of blown engine. This occurred up a steep incline @ highway speeds while stressing the engine. Good luck. I roughly had my vehicle for 2 months. It is now being shipped off to the wreckers with approx 110 thousand km. I will not be buying another ATH10W; nothing to support their repairs in north america.

old thread, but just wanted to point out that the original OEM is an AGM battery as well. Its completely sealed which is what i consider the main benefit as our batteries are inside the cabin. I've seen a lot of regular unsealed batteries leak,vent, etc...

Picasso, thank you for your reply. Appologies, no offense intended. I appreciate any help/sourcing/info that you provide. The documentation I have states that my vehicle identification is ATH10-0003548. Is that the number you are looking for? The vehicle is at the mechanics currently. I am awaiting battery diagnostics/reconditioning. I am trying to source cells in event that I have bad cells. So far, these are my leads: 1) I have heard that gen 1 prius cells may be compatable with our ATH10 Alphard hybrids; I have not cross referenced the Part numbers yet. 2) I may be able to buy a complete gen 1 rebuilt AHR10 estima hybrid battery pack; I do not know if this unit is useful, again I have not been able to cross reference any part numbers yet. I am open to any suggestions for any solutions that you provide. Cheers, Mark

0003548 Why do you ask?

If theres a scenario where we need to replace individual cells rather than an entire battery for the sake of cost savings, I've heard Gen1 Prius has hybrid battery cells. Im wondering if the Estima Hybrid has compatiable battery cells as well. Has anyone already performed such homework?

Thank you for the Replies. Were you able to pull any specific codes that hinted at what part of the hybrid system was failing? In my case, I don't get any dash lights. My ready light is on. Cheers, Mark

Our Alphard Hybrids have a belt based transmission, unlike 99% of the other toyotas which use a planetary gearbox. Perhaps the nissan mechanic can help you, as their CVT transmissions are notoriously bad...

Thank you. I need more information. I just purchased a "washinglee" brand ODB2 lead to work with tech stream Verion 14.30.023 PaulE shows that it can grab full codes about the hybrid battery system in this thread here:

That sounds super sketchy. Is it charging the battery the whole time as you descend to the bottom of the tunnel? What is the battery level according to the display on your the hybrid information system on your display? I wonder if it is cutting out to prevent overcharge; something to do with that?

Can you tell me which version of techstream you use? It is good news that you found a version of techstream that has full readings for the Alphard hybrid. It might be visible under the menu: Help > About *EDIT* I see that you are using version Ver 14.30.023 - 21084 from your screenshots. I am going to purchase the same washinglee lead. Cheers, Mark
