Hello!
I own a 99 Rx300 with around 211,000 miles on it.
I had two long trips (greater than 3 hours) where my A/T temp light came on. If i pulled over for 5 minutes or went below 60 mph the light disappeared. Does anyone know what is happening?
I am about to take it to pep boys. It has been running fine since then

Couple Side notes:
- Mechanic told me to use regular conventional with lucas oil stabilizer with my high mileage car. I feel like this has something to do with it since I first saw this light appear after I used Lucas oil stabilizer

- Car has been giving a burning smell for quite some time but I attribute that to the oil being burned off.

-Catylitic and O2 sensor light is on but i Dont think that has anything to do with the current problem

- Car struggles with changing gears especially from RPM 2- 3
Also does a kick back sometimes when I go into reverse. Please let me know! Thanks!

 

AT light is automatic transmission temperature!

Check the level & condition of the transmission fluid NOW. When was the last time it was changed? Would highly suggest several drain & fills.

 

Yep check tranny fluid and do not under any circumstance do a flush.....I repeat do not do a flush, drain and fill only.

 

I think this is the first time I have ever heard of this light coming on? LexMex used to race his in Mexico, and never had his light come on?

 

Correct, I've never seen it come on.

 

Well Lex, at least he know`s his temp light works! : P But as far as the symptoms, I would start where the others have mentioned^^. And the codes might be affecting the transmission performance.

 

I would check the the tranny fluid immediately upon getting home if I got one of those.

 

when i took it to pep boys (they dont do tranmission)
the guys said sometime the computer will trip the light to come on especially if I have unmatching tires (which I do). I dont know how legit that is but it sounded pretty good lol. Ill be taking it to a transmission shop soon. TY everyone

 

Well, how hard is it to check the condition of the fluid? I have a feeling we'll be seeing a new thread asking for recommendation for a good place to rebuild transmissions.

 

...No
