    I have 44,000 kms on my 2007 Tacoma 4cyl, manual, access cab. I have owned it since new. The Toyota dealer wants to change the fluids in the transmission and the differential. Can anyone advise me about whether or not this is necessary?

    Literally JUST did this last week, I will tell you what I've learned:

    The American Petroleum Institute (API) creates lubrication standards. Our Manual Trannys are rated to take API GL-4 or GL-5 Lubricants. I used A Synthetic GL-5. It works well but because of the higher additives in the API GL-5 Lubricant. Shifting can become slightly stiffer but the gears feel like they are running smoother. I would suggest just a Synthetic API GL-4 for your manual tranny.

    For the rear diff, It requires no less then an API GL-5 oil. I used a Synthetic gear oil 75W-90 with a GL-5 rating and added in the LSD (Limited Slip Differential) Additive. IT RAN LIKE SHIT, the clutches weren't engaging and it was grinding to hell. I had to go to the dealership and get the proper LSD Premixed Toyota certified stuff. Afterwards, it ran perfect.

    Any other questions just asked. So glad I did the switch overs to synthetic.
