Quote, originally posted by krace »djkeev, valid questions.there was no irresponsible driving involved -- to my (35 y.o. guy's) judgment, knowamsayin' but the road was pretty harsh -- not too bumpy (not enough to kill the pan hitting the rocks underneath, which i was careful about anyway), but occasionally soft and very steep, so the car was definitely using a lot of torque (hence my suspicion that it's the clutch).if you're curious, here's a maps link, check out the terrain in question:
http://maps.google.com/maps?f=...&z=13 -- Forest Route 18S02 & Tassajara Rdand of course, could've just been a sh tty transmission.Ok, honest enough answers, thanks, sorry for the suspicions. Did you pull the dipstick? What is the visual color of the trans oil and the smell of the oil. Good Oil is a bright red color and smells almost sweet.Bad oil is BLACK and smells of a harsh acid burnt smell that can send chills down your spine.If it is black and burnt, you could try to change the oil, drop the pan and filter to get all out that you can, and refill with T4 toyota oil. Use theirs, don't go experimenting with one size fits all crap.IF it works, run it for a few hundred miles and change it again, do this again. After about 4 times of this you'll have come close to a complete change of oil being done. If this works jump up and down and praise God. You are lucky and He has smiled favorably upon you!If it doesn't work, shop for a used one or price out a rebuild. I imagine from what you say that you essentially pulled an overloaded trailer for an extended time period with the transmission overheating. That will kill an auto trans in no time flat.Clutches out? Yeah, probably. But the clutches going out hot burned the drums and pack assemblies, the contaminants got into the valve body and hydraulic pistons and you've got a major mess. Even the oil cooler is full of crap and MUST be cleaned / replaced when repairs are made. Don't overlook this, failing to do so will take a good trans and kill it quickly.Let us know what you find.Dave
