I have experienced the same problem. I have also sometimes had it grind into 2nd too. It's not that I havent been pressing the clutch in all the way, I always make sure i feel the floor when i press in the clutch.

Like Kris5597, i have only had this problem on colder days, and after the car warms up or it is warmer, the problem disappears.

 

man thats weird $hit that really bothers me. what is this problem we are all having. I DEMAND WE SPEAK TO A TOYOTA TECH lol.

 

My third always grinds as well ,, but only when im driving if im at a stop and i put the clutch n it let s me shift into third no problem..

 

I think the problem definatly is a result of colder weather, like others have mentioned - once it warms up the problems go away. I'm going to change my fliuds tomorrow and I'll post back with a response.

I've also heard from quite a few people that royal purple makes their car grind. I have RP now and I'll be changing it out for something better.

 

check this out...my buddy with the 400+whp tC grenaded his third gear last night after a pull....scion tc tranny=weaksauce...

 

i was having the same problems with 3rd gear, this isnt relation with weather. I live in Puerto Rico(here cold weather is not cold) and my car when cold engine was doing the grind when shift to 3rd. I talk with my tuner friend about the problem and told me "OIL" I was around 41,000 miles, the Scion manual recomends 36,000 m/t I changed and the problems is gone since that and now I do it every 25,000m.

 

I forgot to mention that Im using Royal Purple Max-Gear 75-90. They make more m/t fluids like SycroMax, that one would make tC to grind shifts..

 

So its ok to replace tranny fluid with gear oil???

Because now my car is gettin stuck in first gear at low rpms

 

Its ok to change your oil, with the Royal Purple Max-Gear 75-90 that I mention you still in the same oil weight that is recomended by Toyota. You can use your preference brand. If you never change your m/t fluid this is the first thing you need to do. If you have a major transmission problem, probably you will notice in the used oil.

 

I've been turbo'd for a while and have never experienced grinding gears only late at night comnig home from work when i get lazy that's when i start to accidentally grind gears

 

ok i just changed the tranny oil it was pitch back i drove it around and atlest my gears arent gettin stuck but my 3rd still grinds!!!

 

Well, you have a major problem. Maybe syncros.

How was the used oil, have metal particles or what did you notice???

Sometimes the used oil can tell you the transmission conditions.........

 

Ok --- I have changed my oil... WHAT A DIFFERENCE!!

Problems:
#1. I was getting stuck in 1st geat at low RPMS
#2. Couldnt put it into any gear on a cold start
#3. Hardest time shifting into 3rd, had to wait for RPMs to completetly drop to get into gear.

These were the conditioins of an 08 turbo tc with a comp clutch and light weight flywheel after bout 20k miles on it. The last 10k Miles were running Royal Purple Max-Gear 75-90.

A few days ago i switched to Motul Gear Oil (http://customizemyscion.com/store/in...roducts_id=265)

Day 1. Smoother shifting, still not much better
Day 2. Can get into geat on a cold start, no longer sticking in second
Day 3. Tranny is working normally again. Happy as can be!

I used 3 Quarts of this oil, and along with the purchase of Motul Synthetic motor oil i got free shipping (coupon code freeoil). What a deal! I reccomend this to anyone who is having tranny problems!

 

well my third gear problem just cam to a head. I was accelerating in third and BOOM, no more third but my other gears work and the tranny sounds like a bucket of bolts
