I purchased a 2001 Toyota Celica for my daughter. It came with a 5 speed manual transmission.

It had about 145,000 miles on the odometer. Four months later, the tranny refused to move the car. There was a lot of gear noise. Removed the tranny and opened it up, and found several gears with teeth missing (gear teeth).

I also noticed, from the markings on the tranny, that this was a replacement tranny from some unknown junkyard.

Purchased another transmission off of eBay. Now 6 months later, I have a lot of whining noise from the transmission. While traveling on the road at about 60 miles an hour, in 5th gear, when I let up on the gas pedal, I will at times, all of a sudden, get the sound of gears grinding together, and a temporary loss of forward movement of the car.

I suspect the problem could be the tranny gears again, and quite possibly the bearings within the tranny.

At times, I will also get a squeal noise, for no apparent reason.

When I installed this tranny, I used 80w-90 gear oil, as recommended from the seller of this tranny, and also the parts store. So lubrication should not been a problem.

I should also mention, that I had to replace the shifting cables, as for one of them had broken. Afterwards, it shifted fine, up until two months ago.

Supposedly this tranny I purchased off of eBay, only had 117,00 miles on it. I would say that I've put maybe 5,000 miles on this tranny since installing it. Anyone have some thoughts on this problem?

I suspect I will hear it's time to replace the tranny again. I should mention all of the other gears, except for 5th gear, work reasonably well.
