Dear Experts,
A number of months ago, I made a posting about a strange faint noise in my car. Search for:
Strange, faint noise in Camry, and How long do CV joints last in Camrys?
The noise started after I had the transmission fluid changed last winter.
I had the CVJ joints, and the wheel bearings checked. They were fine. The best they could say was perhaps the tires had too aggressive a tread. The tires and wheel balancing was perfect.
The car has continued to run fine, albeit with this noise.
Recently I called an alignment expert. He said it could be the differential might need rebuilding.
So I looked this up on the net, and found that Camrys require ATF TYPE IV transmission fluid. Confirmed by the dealer. Dextron III is not recommended.
I called the shop who change the fluid. They said that they used "transmission fluid", meaning Dextron III.
Does it make sense that the wrong fluid is the cause of the noise?
Now, I'm wondering about the fluid in the torque convertor. What percentage of all the transmission fluid is in the torque convertor?
I'm told that flushing the system, like Jiffy LUbe and Aamco does, might just flush debris around the system. If I just do a regular transmission change, with no flush, it will leave some fluid in the torque convertor. The problem I have with Aamco and Jiffy Lube, is that they don't stock Type IV. They use Dextron III, and then use additives to change the properties of it to TYPE IV. So, I'm thinking for the Aamco price ($190.0, I could get two services from the dealer, and get rid of most all of the fluid. Ideas?
Thanks
