#1 of 88 2007 1.5 Liter YARIS Manual Transmission Gear Oil Change by yaris46 Jul 31, 2006 (2:05 pm)
Anyone change the gear oil on their 1.5 liter? I had a hell of a time doing it and wonder if any Toyota Mechanics are out there. DO YOU FILL THE TRANNY TILL IT COMES OUT THE FILL PLUG? I HAVE HEARD YOU ARE SUPPOSED TO LEAVE A FEW MM BELOW THE PLUG OR YOU CAN BLOW SEALS. Anyone QUALIFIED have an answer? Replies to this message: girlcarbuilder (Jun 01, 2007 2:10 pm)

Replying to: nippononly (Jul 31, 2006 3:53 pm) The gear oil from the factory is dino. Synthetic oils are far superior in terms of shifting AND longevity of components. My car has 2000 miles and I have Mobil 1 and a Mobil 1 oil filter on it PLUS I changed the gear oil to REDLINE MT90 which is a vastly superior lubricant compared to whats in the car when it comes from the factory.
#4 of 88 oh, I see by nippononly Jul 31, 2006 (6:09 pm)
well, to answer your question a bit, yes, the manual transmission oil is supposed to be pretty much up to the hole. You should be able to put your finger in and feel the oil level just below your finger. This is a general answer based on my past experience with many other cars where I have changed the gear oil, NOT specifically related to the '07 Yaris. So if you want to be sure, read the manual.

Replying to: nippononly (Jul 31, 2006 6:09 pm) So would you go ahead replace the factory lubricant like Yaris 46? If not, when would you replace it? I get the feeling that you are holding back your knowledge from the rest of us. Replies to this message: nippononly (Aug 01, 2006 6:20 am)
#6 of 88 Manual Tranny Gear Oil & Engine Oil by yaris46 Aug 01, 2006 (2:18 am)
I contacted several service techs, As I had thought, the level is FAR FROM CRITICAL. You can have a little more or a little less, its not THAT IMPORTANT. What IS important IMHO is the QUALITY OF LUBRICANTS used in your car. Thats why I ALWAYS put REDLINE MT90 in all my manual transmissions after break-in period. As for engine oil I PREFER REDLINE but its 9 bucks a quart, so I use Mobil 1 AND a Mobil 1 filter. FRAM IS PROBABLY THE WORST OIL FILTER MADE so if you decide to go synthetic make certain your using a top quality oil filter. Replies to this message: girlcarbuilder (Jun 01, 2007 2:51 pm)

Replying to: lhanson (Jul 31, 2006 6:15 pm) Nah, I wouldn't bother. I have seen Toyota manual transmissions go out to 200K miles with dino oil changed once halfway through, without a problem.   Now as for synthetic vs dino ENGINE oil, well that's the age-old debate on these boards isn't it? I don't bother myself, but I won't say the folks who do it don't gain some benefit from it. It probably provides better lubrication at cold start-up, although Toyota engines seem to be able to go the stretch (200K) without it, so why go to the extra expense? Just change your dino oil every 5000 miles and save some money.
#8 of 88 Not Just Longevity: REDLINE MT90 Makes Shifting ALOT Easier by yaris46 Aug 01, 2006 (9:19 am)
Its not just longevity, For example my Roadster is a 2006 MX-5. The 6 speed was a bit tough to handle for me since I am disabled and have only partial use of my right hand. BEFORE installing REDLINE MT90 I had to reach over with my left hand to shift to 5th and 6th gear. AFTER MT90 the tranny is sSO MUCH EASIER that I no longer need to reach over. NOW THINK, IF A LUBRICANT CAN MAKE SHIFTING EASIER THEN THINK WHAT IT CAN DO FOR KEEPING A HEALTHY HAPPY TRANNY!!

Yeah, I hear you, but my original point stands, as personal opinion ONLY: if the tranny is going to be happy and healthy to 200K anyway, I can't be bothered to change from the manufacturer's spec.

Replying to: nippononly (Aug 01, 2006 12:07 pm) Your absolutely correct. That train of thought also applies to using cheap dino oil and low budget Fram oil filters. They will do the job and as long as you change your oil every 3K you should be OK. As for MY ENGINES I prefer to know I have TOP QUALITY FILTERS AND LUBRICANTS in my engine. Your approach is certainly more cost-effective. My approach wastes money BUT probably adds significantly to drivetrain longevity AND gives me peace of mind. I haven't used a FRAM filter and Dino oil in 10 years! Replies to this message: lhanson (Aug 01, 2006 6:03 pm) yaris46 (Aug 02, 2006 2:19 am)
