2000 tacoma whines when I put it in gear

It whines when you put in in gear. Its loudest when you’re just idling but you can hear it up to around 30 mph then I guess road noise muffles it. Just wondered it anyone else had a similar issue. It doesn’t seem to be affecting how it drives.

 

Auto or manual?

 

Either way my first suggestion would be to do a fluid/gear oil change, especially if it hasnt been done in awhile

 

It's just your unknown supercharger.

Might be your transmission pump if the hum is coming from mid chassis.

 

Ok thanks, I’ll look into it this weekend

Did you every figure out the issue? I think I might be having the same problem, when it’s not in gear it’s not as loud when I have it in gear mine is a 5spd.

 

I didn’t have a chance to check it out. It doesn’t seem to have any effect on driving it. Mine starts whining when you put it in gear. Mines an auto

 

I went through this already. If it shifts normal and only whines in gear it’s the torque converter. I replaced mine about 9k ago and has been quiet since. I used a transtar recon torque converter, got it through a friend for $140.00 as apposed to the $900.00 factory one.

 

Will it cause damage if I don’t replace it?

 

Yes.

 

Bummer, did you replace yours yourself?

 

Yes I replaced it myself. I replaced the front pump seal and rear main seal at the same time. I would replace it sooner rather than later.

 

Im pretty sure my RMS is bad too. Had an oil leak since I bought it. It drips off of the bell housing.
