2Gen GS Trans Whining when shifting
What up CL, This is my first post but I have been CL for a while. I have a 2002 GS300 L-tuned model. I have been getting a whining sound coming from the trans while at high RPM shifts. While in normal driving I have no problems. At times it will also have a delayed shift engagement when going from 2nd to 3rd. Then when if finally engages it hits 3rd pretty hard do to high RPM. Again while normal driving I don't seem to have any problems that I have noticed. I was thinking it was the torque converter but want to make sure of what it is before making the jump. If any direction on this problem it will be a great help.

yeah, superchager it is not. but i did try and have the fluid changed and the places that I tried said no way with 157000 miles no one will touch it. I will have to attempt a method I found on an old post, multiple drains and fills until it looks clean. I will post with updates as they come.

^^So simple, don't pay anyone to do this. It's actually easier thank chaning your oil because you don't have to deal with the messy filter swap. You can get between 2-3 qts out of each drain. Most people get only two based on replies on this board, but I change mine with the car on steep incline ramps and I'm able to get 3 qts out of each change.

This is an old tale that's has traveled throughout the years. If you have super high mileage tranny and the oil has never been changed before, ONLY do a drain and fill. If you do a "power exchange", it could dislodge grime/shavings over the years and block something vital which will kill the tranny. That why you only do a drain and fill to renew some of the oil. This is the main reason why quick lubes won't touch it because they don't know the history of the tranny and most of those places have the exchange machine. I did 4 drain & fills every 5k when I first bought the car to renew the oil. I will now do drain and fill every 30-40k. I have 20k more to go.

I've changed tranny oil on a manual transmission but this^ is just confusing. You flush out the oil when you undo the plug. So how the heck can you avoid the flush? Lol. Do you guys just refill with the same old oil?

Drain the old fluid out and refill with new. This method is not called a flush. Makes no sense to drain out old and refill with old. A flush is a full cleaning of the transmission of ALL oil (converter included) then refilling it with fresh new fluid (about 11-13 qts maybe more). This method is not recommended on higher mileage cars. I recommend that you do some thorough research on transmissions.

Thanks for all the info. Till now I still have not attempted to do the drain and fill, in fear of crazy trans problems. I am in the middle of an LS brake conversion. Now this drain and fill method I have been doing some more research and it seems that this is the way I will go. Adam2562, you say that this was similar to the issues you had, and when the converter was changed did it solve all of the problems? Also what stall speed did you invest in.
