Thanks Todd, nothing like real world info.....I wonder then, say I drove 90 min. to my indie, and he got ready to do a drain/fill after my car sat for 15 min....keep in mind he stated how critical the temp is....logically, it would NOT be "too" hot, right? Because he was the one who explained how the overflow plug worked etc.

When I watched that special Toyota tool and how it's a straw that can vary its length based on the temp, I really thought wow, if only the vehicles had dipsticks, none of this would be necessary....then again I thought this Toyota guy said it's better if customers leave their cars overnight (sigh)

yeah it would be too hot. So I drove home today, 30 minute drive, outside temp 63 degrees, starting fluid temp of 99 degrees, fluid temp reached 164 degrees by journey end. I thought it would surely begin to cool off after getting home and shutting the engine off and waiting a bit. Not the case though, after 30 minutes the fluid temp had actually gone up to 172 degrees. You can speculate as to why this is so but the net is that it would therefore take several hours of cool off time before fluid could be accurately checked, AFTER a long drive. To be more specific, if you're driving more than 10 minutes or so to your mechanic and expecting to get an accurate fluid reading sooner than several hours of cool off time....it ain't going to happen. maybe if you're in the middle of winter in north dakota...maybe

My wife's coolant is that way, when you shut the vehicle off, the temp was correct. If you switch the ignition back on without starting, the gauge rises.

How about this....you have a vehicle driven for 90'minutes. If the check plug is opened, too much fluid will come out, and at proper temp, it is low. But you have no reason to check at this time. You drain hot fluid, replace with cold. Potential overfill.

What will the temp reach at this point? If it is below operating, it can be heated to proper temp. My indie was describing after refilling, pumping new, and letting it overflow, until temp was right, at which point it overflows until correct. It would seem some WS is wasted this way. Otherwise no shops could service vehicles unless left overnight...

yes this should work. In reality I wonder how many techs really go to the trouble of doing the drain/fill accurately. Or doing the flush/refil process accurately either, for that matter.

Next time I'll ask him more specifically...I know that when he decided to do a 2nd drain and fill on one visit, he was taking advantage of the fact that he dropped the car anyway and drove it for about a mile, looking for a clunk sound from the front end (he thinks it's brake pads shifting and demonstrated by tapping the pad lightly and creating the same noise, and stating that the shims are missing), which in turn saved me the labor of the drain/fill (they get $86 per time, so he only charged me for 2 more quarts of WS).

I think my guy has integrity as he explained how the check plug works, stated the temp is important, and said I might have a hard time simultaneously pumping in and letting it overflow and checking the temp all at the same time, but by no means is it impossible to do at home...then he said you have the challenge of keeping the vehicle level, which may require 4 jack stands....not to mention when I asked should I come back for drain and fill #4? He said no, just wait a year and we'll do another one....

p.s. after only one drain/fill at 83k or so, the fluid was still black on the 2nd drain/fill....

again imagine if the vehicle had a dipstick, how a lot of factors are no longer important and it is easier to accomplish...

hi, does anyone happen to know a specific person at a specific lexus dealership in atlanta (or even an indy shop that has techstream) that would properly perform this ATF filling procedure? i have the exact cold symptoms on this trans and i can't confidently get anyone to perform the service for me. i've attempted to get it done at my dealership but the morons keep telling me the level is fine and there's just no way it is. i'm pretty sure they are just removing the drain plug and seeing if some trickles out, so annoying.

Personally, I have always had good luck with Yelp (not just auto or home or restaurants, in general). I hear they have some secret algorithm that keeps the reviews valid....

So this is what they have for your area....I'd call these places and see what they say. On the phone call ask if they install customer parts, and if they do the tranny, can you see your car on the lift and have the tech show/explain the process....can you see the fluid which is drained out. imho an indie worth their salt has no issue explaining and showing you...this is their advantage over a dealership....good luck.

A guy stated he provided brake parts for his IS-F to this shop
