A recent post about the potential percentage of failues got me thinking. I'm curious to gather a data sample from anyone who has gotten high mileage on an original '99-'01 AWD tranny. My '01 AWD RX has 86k miles. Knock on wood I'm still running the original transmission.

For what it's worth, mine has a production date of July 2001. I'm holding out hope they phased in some of the '02 changes later into the '01 production year.

 

Mine is a 2000 awd rx. I have 115,000 miles....I have maintained mine starting at 50,000. FIRST DRAIN AND FILL TRANNY FLUID WAS VERY BROWN...Drain and fill until cherry red, then every 20,000 miles drain and fill again. At 105,000 pulled pan and installed new filter and cleaned magnets....shifts as good as the day I bought it.

 

I have an 01 4WD With 130k with the original tranny and it is still going strong.

 

blueridger,

Mine is a 2001 AWD with the factory towing package. Got 119,000 miles. I've had the Toyota folks (no Lexus dealer nearby) flush and fill the tranny three times in the last six years. No tranny problems thus far. Have had some minor stuff go bad; cruise control, door chime, cabin air actuator. Overall we love the RX!

 

125K+ on '99 AWD and so far so good. No problems and no signs of problems. KNOCK KNOCK on wood !!!

 

2001 Good So far 158,000 km

 

1999 AWD with towing package (transmission cooler), 135,000 miles. No problems yet, flushed and filled at 30,000 (Type IV) and 90,000 (Mobil 1 synthetic). Fingers crossed.

 

2001 AWD with 114,000 miles on original transmission. Next door neighbor has a 2000 with 145,000 on original transmission.

 

2001 AWD with 87K....I am second owner....getting ready for timing belt in the next 10K...

 

99 (3rd owner) with 125K miles. Recent flush and fill. OK so far....

 

2000 AWD w/ 168k miles - recent flush, pan drop, filter and new transmission lines - also no issues to report. prior to this flush, the previous owner had the dealer do it at 90k miles, tho it did not appear they ever dropped the pan or replaced the filter.

 

second owner. just broke 100k. did my timing belt. first owner was an older guy didn't really drive the car that much. i bough it with 50k. i'll be the first to say i drive like a complete ***. but i have had no problems with the car at all. tranny still shifts as smooth as when i got it.

 

I have a 2000 RX300 with about 109,000 miles on the odometer and have the original transmission. My maintenance record involving the automatic transmission consists of:

0 miles – April 2000
26,900 – replaced AT & differential fluid (Lexus dealership)
43,300 – replaced AT & differential fluid (Lexus dealership)
72,500 – drained and refilled AT fluid (DIY)
80,300 – drained and refilled AT fluid (DIY)
83,200 – drained and refilled AT fluid (DIY)
89,000 – drained and refilled AT fluid (DIY)
99,100 – drained and refilled AT fluid (DIY)
100,000 – hit 100k in May 2009

 

We have an 01' AWD with tow package okay at 98K, and an 01' AWD with 115K and so far so good. I have no idea if they are original tranny's or not. Both were bought used 3 months ago, and have no idea how to tell if either was replaced. Aside from the annoying CEL and VSC lights on all the time now in my RX, we are happy with them.

 

I have a 1999 rx300, 192K miles, original owner.
Original transmission
Trans & differential fluid changed at 16, 60, 90, 130
