I've got an old Toyota pickup that's been leaking ATF out of one of the fittings for my oil cooler hard lines going to the radiator. Seems to only happen after highway driving and letting the tranny go into overdrive.
I just did a highway test with OD turned off and it does not appear to be leaking.
Would it be reasonable to assume the oil pressure going to the cooler lines changes based on the gear selected or overdrive?
Also, how much does it cost to get custom cooler hard lines made if mine can't be fixed? There are no parts available anywhere on the planet that I, or my wizard mechanic, can find. It's a rare model and trim that is not popular (2WD) and even finding one in a junk yard is dubious.
My cooler hard lines are not corroded or anything, so the tech replaced an O ring on the fitting, yet it still leaks in OD on the highway. Any ideas on common reasons ATF would leak from the fitting that goes to the tranny from the hard line? Maybe the tech didn't tighen it enough? I'm afraid to strip it trying to nudge it tighter, but that seams like the only logical thing to try considering it doesn't leak in all use cases, possibly just at higher pressures.
