Probably not, did you refill with fluid to the proper level and still have an issue?


Tom is most likely right, Lexus is known for transmission issues. If you want to take a chance you can replace the trans filter and fluid leave enough room for a can of TransX, add the can and start engine make sure it is full, put it in reverse then neutral then drive, put it back into park and shut it off, let the car sit for 24 hours then start it up and make an attempt to drive it. If it does go into gear and drive it won't last long, so get ready to put some cash into a tranny. As it is with your engine, tranny lube is vital, it needs to be clean and changed at proper intervals.


I appreciate these answers I might get ready to buy a new lex. A rebuilt tranny is $3500 lol

Another lex


Just remember all you are buying is a rebadged Toyota.


Yea it’s made by the Company that makes Toyota’s ,Just Like Acura is Made By Honda ,Just about everything is owned by someone else until you get into your High end 175K and up. As for your Lex trans ,Drop the pan ,take out the filter. Disconnect the lines at the Cooling radiator, Blow the Rad. and Lines out with air,There is a Flush solvent for Auto Trans,You’ll have to Gog it. Flush everything with This! Then with new filter in or no pan and no Filter and catch it in a Big Oblong container.Then Drain and blow out all of that if you put the pan and filter in,and Put new filter again and cheap Trans Fluid (Type for GS) and fill it ,let it idle for 15 minutes .Try Shifting through gears Try Moving Forward very little, if you can great. Do not run longer than 25 Min. Drain, New filter and either redline or Lexus trans Fluid.And you just saved $4000! If it doesn’t work with cheap trans Fluid you lost $50 to $70 .I have Brought back 7 Transmissions like This on various cars and a truck ,including an ES and a GS!!! Use common sense ,Your trying to get as much of the Black junk Out, Then putting a Cleaner in to get as much as possible out and any leftover ,then cheap tran fluid to get cleaner diluted and everything lubed, you can even run cheap through twice. Then The Good stuff and Run it Mild for 1 or 2 thousand miles no more and change again, You Should be good to go for 30-40K then,All depends on how bad clutch plates are ,how gummed up springs ,balls,solenoids etc.
