So at 273K miles on the '01 clock, should I feel fortunate that I've had no issues with my trans? I've been doing drain and fills since about 125K miles, more recently every 25K miles. It shifts like butter throughout all 5 speeds and accelerates dropping down a gear on the expressway like it did when it had 19K miles.

 

Thanks...Ruh roh....well, at 87k, I wouldn't think the original owners (2) would have serviced it yet...will just have to see what happens, don't want to invent problems for myself....I believe the tech who worked on the drain and fill knew what he was talking about, he was telling me it would be hard for me to do it properly at home....and they said they will never perform a flush, only drain and fill which would ideally replace 3 quarts at a time....

edit this thread seems to also say it's hard to do properly at home

Hello everyone...So this week I had the original TB/WP finally replaced after 238K miles!! I know some folks wanted pics, so I saved all the parts like I said I would, I just am not sure of how to post pics?? (maybe someone can walk me through it?)...But while in there, I decided to go the extra mile for her (since she seems to be doing the same for me), Had the camshaft seals and fresh plugs done in addition to the extensive items replaced with the TB/WP service...I went with only oem toyota, aisin, denso, etc...Every original part removed would have probably went much further (bearings, pump, seals, tensioner, etc)...However, from the looks of things, only the timing belt was in need of replacing after 14 years. The teeth were fine, the edges were fine , but on the smooth outer side of the belt, you could see "checking" or as it would pertain to a tire, looked a bit like "dry rot"....It was consistant, and basically around the entire belt...It may have lasted many more miles, but then again, old rubber is nothing to mess with. (Thats why I have to swap my class A RV tires out after 7 years even though they might only have 5K miles on them)...So from what I see, when it comes to the LS timing belt, I dont think the mileage is as important as the time (especially if its a lot of highway miles since most stress is applied at start-up). Belts/rubber degrades over time. And after 14 years my timing belt had developed "checking" ....Again, I saved all the parts, but not sure how to add a pic to this site.

 

Well, since there were 2.6 times the number of miles driven on the belt vs 2.3 times the standard replacement time interval I'm going to say the wear was attributed more to mileage than age.

I'm sure you're glad you got it done regardless. Drive on...
