A question of '05 4RUNNER

[benbison]

Hi

A '05 V6 4WD 4runnner, Auto, bought new, and didn't do much for maintenance except change oil on schedules, and changed the 4 tires in this past summer. It ran about 43k miles so far.

Recently I can feel very obviously when it changes gear on the road at 20s and 40s MPH speed, like going through a small bumper, and also feel not as powerful as before. It runs fine and has no any other symptoms like engine warning light etc.

I went dealer and asked, they suggested 60k maintenance including transmission oil change, that I learned from this forum that it doesn’t need.

I hope it is just because of weather change here in NE. It becomes very cold below freezing point. It is a little bit better if I warm up before get on the road.

Any suggestions on diagnoses and maintenance I should do?

Thanks a lot
- Ben

do what the dealer recommends. Should be running tip top in no time

Maybe I can offer a little more "help" ^^ :flamethrwoer2: haha......If your at about 43k then your due for some new spark plugs (30k intervals), fluid change in front and rear diffs and transfer case, and maybe think of switching to synthetic. Up to you

In the cold most oils get "thicker". A thicker oil will also deliver higher pressures in whatever it is pumping through. Higher pressures in the transmission will give it a harder, sort of faster shift. The diffs, x-case, trans, and engine all have oil. The resistance adds up when all these oils get thicker. Your engine has to work that much harder so it may feel a little sluggish. Depending on how cold it is it should go away with 10-30 minutes of driving time or let it warm up a while before driving. Have you ever driven an old stick shift truck? Most of the oldies used 90w oil in the transmissions. When the temps drop below zero you could really feel the difference when trying to shift on those oldies.

Many thanks techmen17. I guess I have to quote around to get these done soon.

Thanks,

Well explained Ron. I guess this is why sometimes it is more obvious than other times.

Many thanks!
