Expected life of a GS400 Engine and Transmission
What is the expected life of a GS400 engine and transmission (in mileage)?
Life of the engine defined as the mileage driven before a major rebuild needs to occur. Same for the transmission.
A lexus mechanic told me 300K miles for both; that seems way high to me.
Thanks

What did you expect?
....it's a Lexus
Seriously though, I've got a first gen GS and that 300K seems to be on the dot. I currently have almost 240K on my motor and it's still going strong. I've busted the tranny but that's because of the way I drive. Alot of us folks on the first gen forum have mileage well into the 200K range with no major problems whatsoever. If my memory serves me correctly, there's a member in the first gen forum who has well over 300K and I think there's a member here in the 2nd gen forum who has over 300K as well.
Here's a thread that might be of interest to you...

Believe your mechanic when he tells you that. As long as you're driving normally and doing regular maintenance, the engine will last at least 300k miles. The V8 engine is very well built.
The transmission can last as long, but due to complexity of an automatic transmission and the wear that it goes through, I would say 250k miles is when you might need some kind of repair done. But you also have to factor in how you drive. My car has 134k miles right now, but the transmission was acting funny. My daily drive is almost stop and go all the way. It heats up the transmission really bad and the clutch-pack started to wear out. My shifting was a bit rough. No signs of slipping however. I poured in a bottle of lubegard and now everything is fine
200k miles of heavy city driving will take more toll than 300k miles of freeway cruising.

I would say that is a conservative estimate. My 98 GS400 is barely broken in at 175K miles. My 92 SC400 now has over 380,000 miles on the original drive train. Only routine maintainance has been required. Probably a collision is more likely to end the car's life than a catastrophic engine or transmission failure.

300k is doable for sure. I just sold my '99 2nd gen GS4 with 150k and still own "old reliable", a '98 2nd gen gs with 253,000 miles on it. Original engine and transmission in both. Old faithful has had two starter motors, two water pumps, and every bit of preventative maintenance done as suggested. Other than a bit of pinging consistently around 2k rpm's, still runs strong and has always started.

I own a LS4 and found this article when i purchased it. Made me have full confidence in Lexus as well as my current GS4 with 145k on it.
Not sure if you guys have seen this or how many miles he has on it now but 555k is pretty crazy.
