ok now as i am free for the writing down the points briefly.
1: As you had described the Engine Breaking at 30 / 40 Km/h is actually not a key feature in this transmission any transmission which doesn't coast well when the throttle is released is known as a faulty transmission. which is unable to coast well at lower ratios. So this is a wrong statement Plz correct the concept of yours. The Coasting helps to improve the fuel economy and if the coasting valve is stucked then the severe engine braking is feel-en when throttle is released in between 40 KM/h and suddenly it releases the vehicle in the range of 10KM/H range. And in S Mode there will be excessive engine breaking.
Yes it is annoying that there is no support available openly regarding these transmissions. BUT YOU CAN GET THAT INFORMATION BY REGISTERING AND PAYING SOME $$$$ TO TOYOTA GLOBAL WEBSITE REMEMBER TO REGISTER THERE FIRST AND GET THE PREMIUM USER ACCOUNT. AND YOU WILL KNOW EVERY THING YOU WANT TO KNOW ABOUT ANY TOYOTA AND LEXUS VEHICLE RANGING FROM SERVICE MANUALS TO PARTS CATALOG.
Regarding your experience about TOYOTA CVTF TC Fluid I had mentioned on some other thread about the UNFIT TOYOTA BADAMIBAGH Packed CVTF TC Oil.YES if you had used that cheap oil than no doubt you are saying well BUT MY DEAR always choose the TOYOTA CVTF TC according to your Region Climatic condition there are 3 different type of CVTF TC are available with different Climatic region.
The Oil supply is only reduced when the oil pressure gets lower than normal. If the oil pressure is too low than normal point the Oil Cooler By pass valve doesn't open hence causing the oil to overheat and deteriorate. the oil cooler Bypass valve Open's at 260PSI and if the pressure is lower than 260 PSI for example 250 PSI the valve wont open. SO this AAAANNNNNNNN LIKE SOUND KICKS IN AND YOU THINK THE OIL IS NOT DOING ITS WORK THIS HYPOTHESIS IS COMPLETELY WRONG. i HAD FIXED A LOT OF VEHICLES WITH THE SAME ISSUE LIKE AEEEENNNNNN AAAAAANNNNNNN LIKE NOISES AND UPON TESTINGS THE FAULT WAS LOW OIL PRESSURE.
OIL Doesn't reduces the Acceleration or increases it. The whole game depends upon oil pressure the more pressure The More torque feeling. Lower pressure and you will feel like driving an Turtle........
I am using liqui moly products from a long time and ATF 1400 is not recommended for the BELT DRIVEN CVTS LIKE TOYOTA's as the viscosity is very lower as compared to the standard's. If you are a fan of liqui moly then the usable oil is TOP TEC 1600 or TOP TEC 1800.
Plz read the Article again. ONLY OIL CHANGE WILL NOT HELP YOU TO RESOLVE THE LOW OIL PRESSURE PROBLEM IN ANY CASE. AND THE ABOVE SERVICE IS NOT A CRAP IT PROLONGS THE TRANSMISSION LIFE AND HEALTH. AND IF YOU THINK TOP TEC 1400 WILL HELP YOU BETTER THAN KEEP ON DRIVING AND WHEN SUMMERS ARRIVES PLZ LET US KNOW ABOUT THE CONDITION.
WE CAN ONLY SAVE THE TRANSMISSION FROM WEAR BY MAINTAINING A GOOD OIL PRESSURE BY FOLLOWING A STRICT MAINTENANCE SCHEDULE.
