Leaking/Seeping Transmission Lines
Hi all, I was underneath my car yesterday (09 ES 350, 60k miles) doing an oil change and noticed oil and grease caked to the back of each side of the firewall and running down over the axles. I also found a small pool of transmission fluid in the splash pan beneath the transmission fluid cooler. It appears fluid is escaping past the factory "pinch clamps." I was wondering if anyone else has noticed this as a problem or has had this problem. I plan to replace the pinch clamps with the screw/bolt style adjustable ones, but I was really curious if anyone else has noticed this. My thoughts are that maybe the WS ATF is too viscous for these pinch clamps, or that maybe under heavy load there's too much pressure for them to withstand leaking/seeping. I'm estimating I may have lost up to 1/3 of a quart up to this point, but can't be for sure. I thought it might be engine oil, but found the back of the engine to be dry and my VVTI return line is metal and not leaking. I'll definitely be checking the fluid level soon, although the car is running and shifting fine.
