I have an 06 Tacoma 4 cyl 5 speed with 31000 miles on it. Do I need to change the gear lube in it ? Changed to synthetic in the rear end at 15,000 miles. If I do what do you think of GL4 redline synthetic ? Thanks for the help

Redline is supposed to be one of the best. You could change it or not. I never changed my old Mazda transmission fluid at all in the 115k I had it and my truck got changed at 238k for probably the first time. I'll probably change the oil on my new Mazda at 100k miles.

you dont need to change it...but i would have changed it fairly soon after new, just because of break in. i would install redline of the correct weight for sure. seems they really have it together for gearbox lubes. 50k-100k is probably a good interval afterward.
ive installed the appropriate redline in my fusions and my f150s gearboxes...been very impressed.

WOW, you don't drive it much?

I change often, but only because all my manual transmissions are operated at peak torque rating about 50% of the time.

Gear oil doesn't go bad sitting idle in the gearcase. Myself, I wouldn't drain it now unless it had water contaimination or was pulling a heavy load all the time.

I would drain it and replace it with:

Does it look like oil or is it grey from wear particles? If grey and yucky, drive and get it hot for better drain then refill with the redline

If it has gray wear particles present in 31k miles, there's bigger issues going on other than gear oil.

Excellent choice. thumbsup

I didn't answer the question: Changed differential fluids, transmission & transfer all at 15,000 & again at 90K. 15K rear end fluid was nasty, front end certainly ready for a change, trans. & transfer fluids looked new. All 4 components' fluids looked fine at 90,000, but were changed anyway.
