Transmission worries...

Hi there,

I have a little (large?) problem with my precious...

My 2001 Yaris T-Sport (Echo RS) has 77.000 km on the clock. I had the transmission oil changed to synthetic (dealer recommended: Castrol TAF-X 75-90W) for the first time about 2 weeks ago. About a week ago my car developed a rather worrying loud grinding/clatter noise from the transmission area. I first noticed it when pulling away in 2nd, 3rd, and 4th gear from low revs. The sound is drowned out by the exhaust in 1st and by the wind in

5th. When I take my foot off the gas the noise seems to go away. The grinding accelerates with the cars speed. Shifting action is unaffected.

I drove the car in this state for another 600 km due to being abroad on holiday when it appeared.

Yesterday I took the car to my friendly mechanic and he took it for a drive... He wasn't too happy. We got her up on a lift, started her up and proceeded to go through the gears as if I were driving it normally on the street… It reproduced the sound. We then turned the engine off and just spun the two front wheels individually by hand, again successfully reproducing the grinding at both wheels.

I’m dropping the car off on Monday so they can take apart the tranny and look inside. I’m hoping for the best…

Anyone experience or hear about such a problem?

Any and all ideas and suggestions are welcome...

Thanks in advance.

Could be any number of things without being able to get my ear to the car and test it but i will say that you should be wary of running the car while its suspended as you can damage the driveshafts/CVs (inner) - they dont like to rotate while at the sorts of angles a fully unloaded suspension geometry allows - ive had a few make some nasty knocking/vibrations when in the air but be fine when on the floor - I dont do that anymore :)

Id be looking to check the simple things first - make sure theres fluid in the box and to the correct level, check to see whether the noise is from the transmission and not an external bearing/joint like the hub/disc area. Would seem odd to have noise develop from a transmission from a fluid change - i cant think of anything off the top of my head that could be disturbed during the process that might cause the noise you suggest.

You can check your owner's manual to see what the correct transmission fluid is. Some manual transmissions require automatic transmission fluid, and if yours is one of them, 75-90W gear oil would be too heavy, although the usual complaint is difficult shifting.

Also, when checking transmission fluid level, also check differential fluid level.

Your dealer was wrong.

Drain and fill, repeatedly, with the Toyota fluid until you've gotten all the Castrol out.

I would be conserned as to weather they filled the trans after draining it. Maybe they forgot to put oil in it

A manual transmission without any lubricant would make a tremendous noise and would probably self-destruct within 10 miles or so. An automatic transmission without transmission fluid would not move.
