Problems after changing oil & adding additive

I have a 1999 Toyota 4-runner with 68,000 miles. I just changed my oil and filter a few days ago. When I added my new oil, I decided to add some STP oil treatment along with it. Ever since I have done this, the vehicle is not running properly. The transmission is not going into gear right away when I put the vehicle in drive or reverse. Eventually it does engage, but it has never done this before and started since I changed the oil. I noticed on the oil dipstick that the oil level was a little high, so I decided to drain some of the oil out of it. I was able to drain some (1/2 quart) oil, but now, I cannot get anymore oil to drain out which is very strange becuae it is still showing that the oil level is above the "full" mark on the dipstick. What should I do now? Why would this effect the tranmission?? Any advice will be greatly appreciated.

 

Sounds like you drained the trans and not the engine oil.

 

No, I drained the engine oil. I'm sure of that. I have changed the oil myself on this vehicle several times in the past without issue.

 

may have been a coincidence..... though the stp oil treatment.... have used it before, its good if you want to add loads more zinc (anitwear agent) thats already found in the oil your using, and good for a engine thats got alot more wear and tear on the engine. (basically thickens the oil alot more) valvoline synpower oil treatment has shown to be alot.... better.

i'm sure you use the wipe off the dipstick and recheck method? well you say you can't get any more oil out of the engine? may sound stupid but the drain plug hole isn't clogged up? because if the engines full, and you've in fact taken the oil drain plug out, you should be getting alot more then a half a quart. also check the trans fluid (auto right?) make sure its to the full line.

 

I just realized.....you may have drained the front diff.

 

I don't claim to be a trained mechanic, but I am sure I drained the OIL. I am not a rookie when it comes to draining the oil.

 

double check everything stick a wire in the drain hole there should be no reason your oil wont drain.
Toyotaman is always been right on the money I am stumped let us know what you find.

 

Oh gosh! I feel like a moron! Just realised I drained the auto. tranny fluid. I had driven the vehicle this weekend to. I refilled the tranny fluid and did the oil the right way this time. I suddenly remembered where the oil plug was when I took another look. Shame on me! The vehicle is driving better now, but is still heitating from time to time when going from a complete stop and then trying to accelerate, but it's not nearly as bad as it was. I'm hoping that will go away as the fluid gets re-cirulated. I'm praying I haven't done irreperairable damage.... any thoughts?

 

i hate to say it, but it does sound like you did some damage to the trans, they can stand being only so low on fluid...., and you said no more came out?...

 

no more came out today. there was still a little in while I was driving it thise weekend, but I didn't drive it today which is when it completley emptied it.

 

well, half a quart in a auto trans.... is low to the point it barely got any lubrication, if any.

 

If that was my vehicle, I'd be trading it in ASAP!!!!!!!!!!

 

Uhm, how much total oil would you say came out of your transmission ?

Mabey you didn't add enough back.
I don't know that much about import tranys but domestic transys will drain ALOT of fluid about 11 quarts not counting the torque converter.( rear whl drive)

I can only speek for myself but I did something like you did to my car along time ago. Don't feel so bad we've all done dumb stuff.

I drained my engine oil and trany fluid in the same day and mistakenly added 5 quarts of motor oil to my automatic trany then didn't realize I left the check valve from the valve body in the bottom of my waste oil pan.
NOT a good day ! " Gee, why won't it shift into 2nd ? "

Good luck.

 

If there was only a half pint of tranny fluid that came out of the tranny, that's a problem... How much tranny fluid did you add overall?

We all do dumb stuff. I didn't realize there was no dipstick on a standard tranny and proceeded to fill my power steering pump with 80W90 tranny fluid while it was -30 celcius.
