    I just bought an 00' TRD SR5 3.4L with a 5MT, with 102k on it. It is blemish free and rust free, looks like it has been extremely well cared for, and a 1 owner. However, the trans whines whines as you accelerate, 1-3rd, and eventually gets drowned out by road noise. Its not deafening, but definitely pronounced. Also, no whine in neutral. I come from the Jeep world, and those 5MT's whine in every gear, just the nature of the beast. Same situation here?

    Also, I'm going to change all my fluids, and I'm sure there is a favored type of fluid amongst the enthusiasts, just like in the Jeep world. What do you recommend?

    Finally, at 102k, is it too late to change to synthetic motor oil? the windshield was replaced by the dealer, so there is no oil change tag, so I don't know what has been used. Thanks!

    Any good synthetic 5w-30 would be fine. Mobil 1 seems to be the fave here, but I use castrol syntec. Same goes for gear oil, 75w-90 i believe.

    I hope a fluid change will cure your noise but from the sound you describe (assuming it doesn't go away) sadly sounds like a input shaft bearing getting ready to sign off.....:eek::eek::eek: sorry dude...:eek::eek::eek:

    The whining noise is just what the 1st gen MTs do, mine does it too. Congrats on the new truck and welcome to tacomaworld :D

    Thanks for the welcome guys, I plan to spend alot of time here, just like I do over at JF. :D I hope 4WD is wrong, I hate to pull the trans already! I am going to get ahold of some MT90 and see if that quiets her down a little, it doesnt bother me, it doesnt whine near as bad at my '46 CJ2! What is the best place to buy MT90? No stores in town carry it.

    Brother, you don't even know HOW bad I want to be wrong, thats a clean 2000 you've got, I know that some trans. make inheritingly more noise than others, but when you said a "whining noise in 1st & 3rd." it instantly reminded me of that same problem I had with my old '83 SR5 4x with the 5 spd, its only about $15 part, problem is it sits on the CENTER shaft amongst all those gear clusters, & basically you dissassemble the tranny (no thanks, been there done did that shit ) Lets just pray for a couple noisy synchro's er something !! :D:D

    Back to square one after the 2001. So...
    I put the same in mine right after I got it at about the same mileage as yours, betard. Before I changed it, the truck was whiney in reverse (and sort of surge-y when backing up my driveway). I know reverse is a square-cut gear and is whiney anyway, but the MT-90 made it a fair bit quieter and stopped the surginess, so I am impressed by it. Also made gear changes a bit smoother in general.

    Yeah, mine shifts a lot better as well. I didn't notice any difference in reverse although I don't back up on pavement very often so its going to be jerky on rough terrain.

    My last company truck was an 04 with 5speed. It was definitely losing the input bearing when we got rid of it. I was hearing a distinct whine in neutral, and in all gears. 5th was loud. My current company truck is an 09 with 5speed, it whines like you are describing. I think that if you have an input bearing wearing out, you have a ways to go before it HAS to be fixed.

    BAD NEWS. Although I can't hear it in neutral at idle, I sat and revved the motor, and the whine goes up and down with the motor, without the trans spinning. Gotta be that bearing. My dealer does a 1 month 50/50 warranty, but I assume they wont want to do anything if there is no obvious failure? What are your thoughts?

    Im thinking you can go a while. I still think you should get a second opinion though just to make sure it isn't normal. idk, its up to you.

    Oh I'm going to take it to the shop for sure, and giving their opinion to the dealer. I want to handle it tactfully, as it is a small dealer that does carry very clean cars, and they have been extremely nice. Owner is friends with my boss, so I'm sure we will figure something out. Just frustrating. I was always told Toyotas were indestructable, and my first one has issues!

    Take it in, see what they say. But it will probably go for awhile. I had been listening to my work truck make noise for 25K miles. If it was my own truck, yeah it would piss me off, but it never popped out of gear or anything like that.

    I had a '96 4 cyl 5MT a coupe years ago that had the same whine. Not intolerable but noticeable. I just picked up an 01 4cyl 5MT this month and it has the exact same whine. Funny enough though, as I was leaving my dads house after showing it off, he called me to ask me why it whines so much when accelerating. I kinda huffed it off, but this discussion has me wondering. I'll check my tranny with the same steps the OP took to see if mine does it too. But literally, both trucks, same exact sound... both having around 125k on the clock.
